Subject: [PATCH 011/345] Release 2.1.0, and say that the Home Assistant floor
moved
v2.0.8 is the last release; sixteen commits of v1.0 schema work have landed
since with no version to file them under, and `pyproject.toml` had drifted a
patch behind `manifest.json` besides. Both now read 2.1.0.
The entry leads with the Home Assistant requirement because it is the only
change here a user can be hurt by. 2026.8 replaced the two device-registry
calls this integration depends on and the replacements do not exist in
2026.5-2026.7, so no single release runs on both; anyone older stays on 2.0.8
and HACS will not offer them this. That is worth a sentence in a changelog
rather than a silent failure to update.
Everything else is additive or an improvement, and is written for someone
reading release notes rather than a diff: the MID device and its Grid State
entity, self-reload on a firmware schema change, `DSM Grid State` becoming
sensed rather than inferred, `Grid Islandable` surviving on MID presence, and
the enum sensors that used to advertise only "unknown". `battery.model`
changing value is called out, because it is the one existing entity whose
reading moves.
Emphasis in the new section uses underscores to match the file. MD049 is
first-wins, so an asterisk above the existing `_must_` lines silently made
every one of them a violation.

All notable changes to this project will be documented in this file.
+## [2.1.0] - 8/2026
+
+Support for the eBus v1.0 (parent/child) data model your panel moves to on firmware r202633 and later, and a clean transition when it does.
+
+### Requires Home Assistant 2026.8.0 or newer
+
+This release raises the minimum from 2026.5.4. Home Assistant 2026.8 replaced the two device-registry calls this integration relies on — the old forms stop
+working entirely in 2027.8 — and their replacements do not exist in 2026.5 through 2026.7, so there is no version of this release that runs on both. If you are
+on an older Home Assistant, stay on 2.0.8 until you can update; HACS will not offer you this release.
+
+### Added
+
+- **Your panel's Microgrid Interconnect Device appears as its own device** on the new data model, carrying **Grid State** — the health of the utility supply
+ itself, which the previous firmware never reported. Everything about it is additive; no existing entity moves or changes id.
+- **The integration notices a firmware upgrade and reloads itself.** A panel that becomes v1.0 while Home Assistant is running used to keep reading the tree
+ with the old parser, reporting every circuit as missing until you reloaded by hand. It now detects the change, reloads, writes a log line, and raises a
+ one-time notice explaining what changed.
+- **Grid-forming device name** as an attribute on the GFE sensor.
+
+### Changed
+
+- **`DSM Grid State` is now more trustworthy on the new data model.** It keeps its entity id and all of its history. Previously it was _inferred_ — from the
+ battery if one was fitted, otherwise from the dominant power source and whether power was crossing the grid connection. It now reads the islanding state the
+ Microgrid Interconnect Device actually senses.
+- **`Grid Islandable` keeps working** across the upgrade. v1.0 publishes no panel-level islandable property, so the entity now reflects whether a Microgrid
+ Interconnect Device is present, which is how v1.0 says backup capability is detected.
+- **Battery model** may read differently after upgrading: the new data model separates the human-readable designation from the SKU, and this entity now shows
+ the designation. This is a library-level normalisation applied to both data models, so it happens once, at this release, rather than unpredictably during a
+ firmware update.
+
+### Fixed
+
+- **Enum sensors advertise the states they can actually report.** Nine sensors declared only `unknown`, so `DSM Grid State` sitting at `On Grid` showed
+ "Possible states: Unknown". The lists are now derived from the translations and checked against them by a test.
+- **The GFE override button reads the right signal** for deciding when it applies, so it is no longer permanently enabled on the new data model.
+- **Sub-devices link to the panel by registry id**, replacing a form Home Assistant deprecated in 2026.8. No user-visible effect; required for the version bump
+ above.
+

Subject: [PATCH 012/345] feat(mid): show the firmware and hardware revision
the MID publishes
r202633 documents model, firmware-version and hardware-version on the MID's info
node. mid_device_info could set a model and a serial and nothing else, so a user
saw a Microgrid Interconnect card with no firmware row beside a battery that had
one -- the battery's identical property having been mapped from the start. The
library now carries both (span-panel-api SpanMidSnapshot.software_version /
hardware_version); this reads them.
Passed through unguarded, exactly as bess_device_info does. DeviceInfo omits a
None field and renders an empty string as a present-but-blank row, so `or ""`
would invent a firmware row reading empty for a panel that published nothing --
worse than no row, because it asserts the panel answered and the answer was
nothing. A test pins that distinction.
No schema conditional, deliberately: flat publishes no MID at all, so has_mid
keeps every caller of this builder off a flat panel and a branch here would be
unreachable code implying a case that cannot arise. The comment saying so
originally used the DUAL-SCHEMA token and was caught by
test_every_schema_conditional_is_findable, which asserts the exact set of modules
that branch on schema -- util.py does not, and the marker is a grep target rather
than prose. Reworded rather than widening the list.
Corrects a stale comment in the existing card test. It read "the producer
publishes no MID model today", which stopped being true when panelbench started
valuing info/model; that case is the fallback path now, not the only path.
PV is deliberately not included. The integration has no PV device -- PV metadata
reaches a user as three diagnostic sensors on the panel -- so consuming
SpanPVSnapshot.software_version would mean adding a fourth, which is a new
user-visible entity and a product decision rather than a mapping change.

Subject: [PATCH 014/345] chore: pin span-panel-api 3.0.0b4 and both schema
adapters
Sources point at the span-panel-api-p3 worktree so this branch develops against
the field-metadata changes without disturbing the baseline pair.

Subject: [PATCH 015/345] chore: pin b4 in project dependencies and document
fixture provenance
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The earlier pin commit updated manifest.json and the uv sources but left
[project] dependencies on b3 — inert locally because the sources override it,
operative on a clean resolve. requirements_test.txt is read by nothing; uv sync
reads [project] dependencies, so that is the file that had to change.

+# Adapter fixtures
+
+Real schema-adapter inputs, used by the field-path conformance tests via
+`tests/adapter_fixtures.py`. They are **committed rather than generated** so the
+test suite has no cross-repo dependency and CI needs no checkout of the library.
+The cost of that choice is that they go stale silently — hence this file.
+
+## Provenance
+
+Both are byte-identical copies from the `span-panel-api` repository:
+
+| File here | Source in `span-panel-api` |
+|---|---|
+| `schema_zero_types.json` | `tests/fixtures/v2/homie_schema.json` |
+| `schema_one_tree.json` | `tests/fixtures/parent_child_tree.json` |
+
+Refresh by copying them again. If a copy changes shape rather than content, the
+loader in `tests/adapter_fixtures.py` is what needs updating — note that
+`schema_one_tree.json` is a **dict keyed by device id**, whose `$description`
+value is a **JSON string**, not a parsed object.
+
+## Derived variants
+
+Both are produced from `schema_one_tree.json` by dropping every device whose
+parsed `$description["type"]` contains a marker. Regenerate with:
+
+```bash
+uv run python - << 'PY'
+import json, pathlib
+
+tree = json.loads(pathlib.Path("tests/fixtures/schema_one_tree.json").read_text())
+
+def drop(marker: str, out_name: str) -> None:
+ kept = {
+ device_id: topics
+ for device_id, topics in tree.items()
+ if marker not in json.loads(topics.get("$description", "{}")).get("type", "")
+ }
+ pathlib.Path(f"tests/fixtures/{out_name}").write_text(json.dumps(kept, indent=2))
+ print(f"{out_name}: {len(tree)} -> {len(kept)} devices")
+
+drop(".bess", "schema_one_tree_batteryless.json")
+drop(".pv", "schema_one_tree_no_pv.json")
+PY
+```
+
+Each must remove **exactly one** device (13 -> 12) and must retain the panel and
+both lugs devices. A variant that removed more would make the conformance tests
+pass for the wrong reason. Note `bess-mid` is typed `energy.ebus.device.mid` and
+correctly survives the `.bess` filter.
+
+## Why these exist
+
+`schema_one_tree_batteryless.json` proves a panel with no BESS produces **no**
+`battery.*` entries — hardware absence, not degradation.
+`schema_one_tree_no_pv.json` proves the same for a panel that has power-flows
+telemetry but no PV device, which is the case telemetry-based capability
+detection gets wrong.

Subject: [PATCH 016/345] refactor: declare snapshot field paths on entity
descriptions
Retires SENSOR_FIELD_MAP. The declaration now lives on the object that reads
the field, so the two cannot drift. Also drops the key-based dedup, which
silently discarded descriptions sharing a key across device classes.

Subject: [PATCH 017/345] refactor: return a frozenset of producible field
paths
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
declared_field_paths() returned dict[str, bool] whose value was always False —
derived descriptions are skipped before the assignment, so no key could map to
True. It is a set, so return one.
Also splits the residual readers by empirical producibility against both
schema adapters. Readers both adapters produce join RESIDUAL_FIELD_PATHS;
$target echoes, topology-derived values and schema-conditional fields go to
RESIDUAL_DERIVED_PATHS and stay out of the producible set.
Adds the enumeration test that was missing: a description inheriting the
declaration mixin but setting neither field passed silently and was dropped
from every gate.

straight off a snapshot field that one adapter publishes and the other does
not — so "derived" misdescribes why they are exempt. The docstring now names
both reasons a path lands here.

Fourteen further snapshot-field reads outside any entity description were in
neither bucket, including three in the same DeviceInfo call as bucketed mid.*
paths and one in the same availability property as battery.connected. That
adjacency is how the next reader concludes the constant is complete when it is
not.
All fourteen are exempt — none is producible by both adapters — so
declared_field_paths() stays at 46 and the gate is unchanged.

Subject: [PATCH 023/345] test: introspect binary sensor declarations and fail
on unmapped classes
The gate in declared_field_paths() walks the binary sensor collections too,
so their declarations were producible-checked but never checked against
their readers. Cover them, and pin the introspected description set against
the gate's own so a new platform collection cannot be gated without being
verified.
An entity description class absent from the root-prefix map is now reported
as a failure rather than skipped -- a silent skip is the drift this test
exists to catch.

Subject: [PATCH 029/345] fix: excuse the known-bad schema_0 circuit power unit
label
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
SPAN firmware declares the circuit active-power property as kW while publishing
watts. The sibling lugs device declares W for the same quantity, the library
consumes the value unscaled, and our sensor declares W — so the label is wrong
and the reading is right. Left unhandled, every schema_0 panel would raise a
permanent unit mismatch its owner cannot act on.
KNOWN_BAD_SCHEMA_UNITS excuses only the exact declared unit, so a future
firmware declaring anything else for the same field is still reported.
Also: exclude RESIDUAL_EXEMPT_PATHS from `unread` (they are read, just not
required of both adapters — 10 of schema_0's 17 were mislabelled); drop the
`| None` arm of evaluate_field_metadata so the sentinel cannot be answered with
"healthy"; and evaluate both real adapter fixtures in the tests rather than only
synthetic single-entry dicts.

Subject: [PATCH 030/345] feat: raise Repairs for unresolved fields and unit
mismatches
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
One issue per (entry, class, field path) so a dismissal cannot swallow a later
finding and one panel cannot clear another's, re-raised idempotently so
reconciliation never clears a dismissal. Issues are non-persistent: derived
from live state and re-asserted at startup from the tombstone that carries the
dismissal forward.
A produced field nothing reads stays a sanctioned addition — debug log only.
Adds async_remove_entry, which core does not provide, so a removed panel does
not leave its notices behind. Entity enumeration in a payload is a count plus
three examples, matched by the description's user-friendly suffix rather than
the snapshot field name.

Subject: [PATCH 031/345] fix: record affected entities from the entities
themselves
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The Repairs named the entities a dead field takes down by re-deriving
unique_ids from entity descriptions through get_user_friendly_suffix. Only
circuit sensors build ids that way. Panel-data sensors use
get_panel_entity_suffix, whose mapping deliberately disagrees for six keys
(instantGridPowerW is current_power, not grid_power), and binary sensors use
the raw camelCase key, which a lowercasing helper can never match — eight
declared fields resolved to nothing, so the notice read "0 entity/entities are
affected" while the sensor was dead. endswith("power") also claimed every power
entity on the panel.
Entities now record field_path -> entity_id on the coordinator as they are
added to hass and withdraw it as they leave. Both halves come from the entity,
so no unique_id builder is consulted and nothing can drift from them.
Reconciliation moves out of the first-refresh path into
async_sync_schema_repairs, called after the platforms are forwarded: setup
awaits the first refresh well before any entity exists, so reconciling there
reported zero affected entities on every fresh install regardless of the
suffix bug.

A derived entity reads several fields or none, and the circuit switch carries
no entity description at all; attributing either to a field would blame it for
a loss that may not have taken it down.

Subject: [PATCH 033/345] fix: retry schema validation while the answer is
unknown, and name residual readers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Two defects, both surfacing as a Repair that tells the user nothing.
The once-only guard was set before validation ran, so a first pass landing in
the metadata-not-ready window — which an ordinary reconnect opens — spent the
guard on a pass that answered nothing and left findings at None for the life of
the entry. The guard now sets only once findings exist, and a pass that first
succeeds after setup reconciles itself rather than waiting for a reload.
Five field paths are read from entity code rather than a description, so
nothing registered them and a dead circuit.relay_state reported "0 affected"
while every breaker switch was out. The switch, select and circuit sensors now
declare those reads; a test pins the declarations against RESIDUAL_FIELD_PATHS
in both directions.
The unresolved-field notice no longer promises the entities will go
unavailable: losing a circuit's name or tabs degrades naming and attributes
without taking the entity down.

Subject: [PATCH 034/345] feat: mark entities unavailable when their field is
unresolved
An entity whose declared snapshot field the adapter cannot resolve now
reports unavailable instead of publishing a parsed default. The probe lives
on SpanPanelEntity so binary sensors are covered too, and runs ahead of the
grace-period branches in SpanSensorBase and SpanPanelBinarySensor, which
return True on their own.

Subject: [PATCH 035/345] fix: evse_ev_connected declares evse.status instead
of claiming derived
It reads exactly one field that both adapters produce, which is a
declaration. Classified derived, it was skipped by _declared_field_paths:
the Repair for a dead evse.status never named it and the availability probe
never fired for it, while its sibling evse_charging got both from the same
field. The derived docstring now states the rule as a countable test, and a
new introspection test fails any derived description that reads exactly one
producible field.

Subject: [PATCH 037/345] fix(repairs): do not raise a Repair nothing the user
owns is affected by
Both schema Repairs claim something the user owns is broken: a sensor is
dead, or a reading may be wrong. A field path no enabled entity reads
supports neither claim.
`vendor_cloud` is `entity_registry_enabled_default=False`, so it is
registered and never added to hass and never self-registers with the
coordinator. A fresh install against the flat simulator therefore raised
"`panel.vendor_cloud` ... 0 entity/entities are affected (for example:
none)" beside two genuine notices, which is how a category of Repair
gets ignored.
Both classes now look up the affected entities first and skip the finding
when there are none, logging the suppressed path at debug. The unit
mismatch class did not look them up at all before. A suppressed path
never enters `wanted`, so the existing reconcile sweep deletes an issue
whose last affected entity has gone rather than leaving it orphaned.
The unit mismatch notice now carries the same count and bounded examples
as the unresolved one; every locale already had the fragment translated
for the other message. The `span_panel_schema_issue` payload now lists
the paths that actually raised, so a partly suppressed pass cannot name
a path that a fully suppressed pass omits entirely.

A third condition, a produced field nothing reads, is a sanctioned addition and
stays in the debug log.

+Every Repair here claims something the user owns is broken, so a finding whose
+field path no enabled entity reads is not raised at all. Disabled-by-default
+descriptions are registered but never added to hass, so they never self-register
+with the coordinator and a finding against one has nothing to name; telling the

Subject: [PATCH 038/345] feat(repairs): notice entities that were added
disabled
A release that adds a diagnostic with entity_registry_enabled_default=False
grows nobody's entity list uninvited, which is the point -- and is also why
the addition reaches the user through nothing at all. battery.part_number
shipped that way and was only found by opening the device's disabled-entity
list on a hunch.
Setup now snapshots the entry's registered unique_ids immediately before the
platforms are forwarded and, once they are up, raises one Repair naming
everything that is both newly registered and disabled_by INTEGRATION.
Silent on a first install: with nothing registered beforehand every entity is
new, so the notice would name the whole integration.
Keyed on the entry AND a digest of the exact set of new unique_ids, for the
reason that forced per-field ids on the degradation Repairs --
async_get_or_create's update branch preserves dismissed_version while
replacing placeholders, so an entry-wide id would rewrite a notice the user
put away instead of raising a new one.
An event rather than a condition, which needs three things together: it is
persistent, because the diff cannot produce it twice and a tombstone would
vanish unread at the first restart after the upgrade; the defect reconcile
pass cannot reach its ids, so the startup that raised it does not then delete
it; and raising is skipped outright when the id already exists.
IssueSeverity has no informational member -- CRITICAL, ERROR, WARNING -- so
WARNING is the mildest available, the floor panel_upgraded_to_ebus_v1 already
settled on for the same reason.

A third condition, a produced field nothing reads, is a sanctioned addition and

+One further notice lives here and is not a defect at all: entities that this

Subject: [PATCH 039/345] fix(repairs): state the observation, not a cause the
trigger cannot establish
The new-entity notice fires on any entity newly registered for the entry with
disabled_by INTEGRATION, but the text asserted one specific cause: "This
update added data your panel was already reporting but this integration did
not yet expose."
Three ordinary paths fire it with no update involved. A breaker added to an
established panel brings a per-circuit CIRCUIT_BREAKER_RATING_SENSOR, which
is disabled by default. Enabling solar in the options flow is the user's own
deliberate action, reported back to them as something an update did.
Attaching a BESS brings BESS_METADATA_SENSORS with it.
A feature whose purpose is telling the user the truth about an addition must
not tell some of them something false. The text now states what was observed
and offers the causes as possibilities. Rewritten in strings.json and all
five locales in the same pass -- a partial edit would leave some users with
the false claim.
Also from review, both cheap:
The already-raised guard was unobservable and its comment oversold it. It
does not prevent duplication -- the shared id does that. It prevents a repeat
of the same set from rewriting the text of a notice the user has already
read, via async_get_or_create's update branch. A test now pins that through
the one path where the diff can repeat: an entity removed from the registry
and later re-registered under a different name.
_ours and _new_entity_notices were the same function twice, now one
_scoped_issue_ids taking the prefixes it may see. The reconcile pass passes
the defect prefixes only, which is the reason the scope is a parameter at
all; removal passes every prefix.

Subject: [PATCH 040/345] test(field-paths): assert every exemption's reason
against both adapters
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
`RESIDUAL_EXEMPT_PATHS` was 26 entries whose reason for being exempt lived in a
prose comment that nothing executed. An entry could be mislabelled from the day
it was written, go stale when the library changed what it publishes, or become
producible by both adapters — at which point it should be promoted to a
declaration — and no test would notice any of it.
Make the reason part of the data: `Producibility` (NEITHER / SCHEMA_0_ONLY /
SCHEMA_1_ONLY, with no BOTH member because such a path is not exemptible), and
`RESIDUAL_EXEMPT_PATHS` as a Mapping from path to that annotation. Four new
conformance tests build both adapters' metadata from the vendored fixtures and
check each annotation against it, demand promotion for anything both adapters
produce, pin the inventory so an entry cannot quietly disappear, and check each
exempt path still has a reader in the package source.
Bookkeeping only: `declared_field_paths()` returns the same 47 paths, verified
by diffing the dumped set against the previous commit's. The sole runtime
consumer needs the key view (schema_validation.py:110).

+`Producibility.NEITHER` for values no adapter publishes a metadata row for —
+Homie `$target` echoes, values the library assembles from panel topology, every
+`mid.*` field; `SCHEMA_0_ONLY` / `SCHEMA_1_ONLY` for schema-conditional fields

-**Produced by only one adapter** — schema-conditional fields. The gate requires
-a path to be producible by *both* adapters, so a field present on one schema and

-these are read straight off a snapshot field, that field just is not on both
-schemas.
+The annotations are not documentation. `tests/test_field_path_conformance.py`
+builds both adapters' metadata from the vendored fixtures and asserts every
+entry's annotation against what those adapters actually produce, so a stale
+reason fails the build instead of misleading a reader. A path that becomes
+producible by both fails there too, demanding promotion to a declaration.
Deliberately **not** returned by `declared_field_paths()`. Recorded here so the

Subject: [PATCH 041/345] refactor(field-paths): derive residual paths from the
entities that read them
`RESIDUAL_FIELD_PATHS` restated, as a module constant, exactly what the four
entity classes already declare in `_residual_field_paths` -- the same fact in
two places, kept coherent by a bidirectional test that was itself a third copy
of the class list.
The entity's copy is the one that has to be right: it is what
`async_added_to_hass` registers, so it is what a Repair names when a field
dies. So the constant goes and `residual_field_paths()` collects the paths off
a recursive `SpanPanelEntity.__subclasses__()` walk instead, with the platform
imports deferred for the same cycle-avoidance reason `declared_field_paths()`
already defers its own.
A walk sees only what has been imported, which is a hole where a residual could
go missing silently -- the derived set would just be smaller, and everything
downstream of it is monotone in the direction that hides that. Closed the same
way the conformance gate closes it for `field_path=`: an AST scan for
`_residual_field_paths` tuple literals over the package source, asserted
against the walk in both directions.
`declared_field_paths()` returns the same 47 paths.

Subject: [PATCH 042/345] test(field-paths): derive the recorder prefix from
the value_fn annotation
The class-name map had to be edited for every new description class -- ten
entries and growing -- and a class missing from it was the original silent
skip, patched into a recorded mismatch but not removed.
Resolve the snapshot type from the value_fn annotation instead
(get_type_hints, so the stringified annotations resolve) and map the five
snapshot types to their prefixes. A new description class over an existing
snapshot type now needs no map edit, and its prefix cannot be wrong: it comes
from the annotation mypy already checks the value_fn body against.
An unresolvable annotation or an unmapped snapshot type raises, and both
callers record it as a mismatch naming the description -- never a skip.

Subject: [PATCH 043/345] feat(field-paths): say why a description is derived,
and verify the reason
`derived: bool` conflated four situations -- reads nothing, reads several
fields, reads one field only one adapter produces, and the mistake of marking a
single producible field derived. That last one is how evse_ev_connected went
unnoticed: it declared no path, so the Repair never named it and the
availability probe never fired for it.
Replace it with `derived: DerivedReason | None`, three variants, each a claim
the recorder can check: NO_SOURCE_FIELD reads nothing either adapter publishes,
MULTIPLE_FIELDS reads two or more, SCHEMA_CONDITIONAL_FIELD reads exactly one
that only one adapter produces. There is deliberately no variant for "reads a
field no adapter produces" -- the recorder cannot tell that from reading no
field at all, and an unverifiable variant is what this replaces.
test_derived_reasons_match_what_value_fns_read asserts every one of the 11
declarations against what its value_fn actually reads, alongside the existing
single-producible-field check.
An enum member is truthy and None is falsy, so every consumer -- field_paths,
entity.py's declaration and probe gates -- is unchanged. The
declares-exactly-one pin needed the comparison made explicit: bool != enum was
true for every description, declaring and derived alike.

Subject: [PATCH 044/345] test(field-paths): pin the residual read no other
entity class claims
circuit.relay_requester is declared by one class alone. If that class stopped
declaring it the path would leave residual_field_paths() entirely and the
producible gate would quietly stop covering a read that is still happening.
Asserted through the Repair's own output, so it fails on the observable
consequence rather than on one list disagreeing with another.

span_panel_api, the parent/child tree to span-panel-api-schema-1, since a
retained-topic tree needs the vocabulary that interprets it.

Subject: [PATCH 046/345] feat(sensor): surface the shed forecast as two
duration sensors
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The panel has published `energy.ebus.capability.shed-forecast` since r202633 and
nothing read it. Its two live estimates are the highest-value unread properties
on a v1.0 panel — how long before the panel starts shedding circuits, and how
long before the battery is spent — so they land as sensors that are enabled by
default and not filed under diagnostics. Surfacing them behind a disabled
default would be surfacing them in name only.
The two hypothetical-full-charge figures and the confidence enum ride as
attributes on the sensor each one refines. They answer "what would this
installation give me from a full battery", which moves when the hardware does
rather than as the battery drains; separate entities would put a near-constant
on a graph beside the countdown it qualifies. Which twin belongs to which sensor
is carried on the description, not compared against `description.key`, so a
rename cannot silently swap two plausible-looking durations.
Creation is gated twice, because absence has two shapes. `has_shed_forecast`
answers whether the panel publishes the capability at all — false on every flat
panel — and joins `detect_capabilities`, so a panel that gains it on a firmware
upgrade picks the sensors up on the reload the coordinator already performs. The
per-description gate then asks whether *this* estimate is among what the node
publishes: the catalog marks all four times SHOULD rather than MUST, so a
partial node is legal firmware and the half it omits must produce no entity
rather than one permanently unknown. The presence test is the description's own
`value_fn`, so the gate cannot drift away from the read.
Both descriptions are `SCHEMA_CONDITIONAL_FIELD` rather than declaring a
`field_path`: the producible gate demands a path both adapters emit and no flat
panel publishes this capability. The two live estimates join
`RESIDUAL_EXEMPT_PATHS` as `SCHEMA_1_ONLY` — schema_1 maps them, which buys unit
validation against the panel's own `$description` — and the three refinements as
`NEITHER`, matching the `mid.*` attribute reads.
Tests build a real snapshot through the real schema_1 adapter over the vendored
capture, and read every expected value out of that capture rather than writing
it as a literal. Each reading is then proved by republishing it, deleting it, or
dropping the node. Hardcoding the captured 3037 and crossing the two full-charge
twins fails seven of them.

+## [Unreleased]

+### Added
+
+- **Backup planning, in minutes: two new sensors on panels running the v1.0 data model.** **Time to Priority Shed** is how long before the panel starts shedding
+ circuits, and **Backup Time Remaining** is how long before the battery is spent. Your panel has been publishing both since firmware r202633 and nothing read
+ them; they are the numbers you would actually set an alarm on, so they are enabled by default and sit beside the power and energy sensors rather than under
+ diagnostics.
+- **Each forecast sensor carries the refinements that qualify it** as attributes: `full_charge_time_to_priority_shed` / `full_charge_total_time_remaining` —
+ what the same estimate would be from a full battery — and `forecast_confidence`, the panel's own `LOW` / `MEDIUM` / `HIGH` assessment of the estimate. They
+ refine a number already on screen rather than adding two near-constant entities to your entity list.
+- Both sensors are created only where the panel publishes the estimate behind them. A panel on the older data model, or one whose firmware publishes only part
+ of the forecast, gets no entity for what it cannot report rather than one permanently unknown — and a panel that gains the capability on a firmware upgrade
+ picks the sensors up on the reload the integration already performs.
+
## [2.1.0] - 8/2026
Support for the eBus v1.0 (parent/child) data model your panel moves to on firmware r202633 and later, and a clean transition when it does.

Subject: [PATCH 047/345] feat(field-paths): degrade a schema-conditional
entity like any other
A `SCHEMA_CONDITIONAL_FIELD` description named no field, so the two halves
of the degradation apparatus both skipped it: `_reads_an_unresolved_field`
required `not description.derived`, and `evaluate_field_metadata` only ever
asked the adapter about `declared_field_paths()`. Such an entity therefore
kept publishing a parsed default when its field went unresolved, and the
Repair for that field could name nobody -- which the suppression rule turns
into no Repair at all. That is the `evse_ev_connected` failure reached by a
second route, and Task 1 had just shipped two entities down it.
The exemption is from the *producible* gate, which is a claim about the
other adapter. The adapter that is running still publishes a metadata row
for the field and still reports whether the panel resolved it. So the
description now names its source field alongside `derived`: `field_path`
answers "what is this entity's value", `derived` answers "why is that path
outside the both-adapters gate", and only the first is what the Repair and
the availability probe need.
The deliberate exclusion is untouched and now has a test of its own:
`circuit.name` and `circuit.tabs` are residual reads that decorate a
reading rather than being it, and a circuit's power is still true when they
are gone. `evaluate_field_metadata` widens to the descriptions' source
fields, not to every non-NEITHER exemption, for exactly that reason --
device_info fields and circuit attributes stay out.
`panel.dominant_power_source` joins RESIDUAL_EXEMPT_PATHS. The
`grid_forming_entity` sensor read it while it was enumerated nowhere, so
the evaluator logged it as produced-but-unread with an entity reading it.
`test_schema_conditional_descriptions_name_an_exempt_field` is what makes
that omission impossible to repeat, and the introspection proxy now checks
the named path against what the value_fn reads.

Subject: [PATCH 048/345] test(declarations): fail when the panel declares what
nothing reads
The producible gate asks whether an adapter produces what we declare we
read. It cannot see the converse: a property nobody reads is absent from
every list the gate consults, so it is invisible by construction.
`panel.wifi_ssid` is what that costs -- flat surfaces it, v1.0 declares it,
schema_1 maps nothing to it, and its exemption said SCHEMA_0_ONLY, which
was true. Every check agreed and a user upgrading lost an attribute.
Consumption is decided by experiment rather than by a list, because a list
is what made a new property invisible to begin with: republish one declared
property with a legal different value, rebuild the snapshot through the
real schema_1 mapper, and see which snapshot fields moved. Nothing here
restates `_PROPERTY_FIELD_MAP`, the lugs direction tables, the topology
readers or the device_info builders -- the probe sees all of them, and sees
them the way a user does.
Stricter than "mapped by `_PROPERTY_FIELD_MAP`" on purpose. A property the
library reads into a snapshot field no entity, attribute or device card
touches has reached nobody, so `circuit.is_240v`, `evse.part_number` and
`pv.software_version` are baselined rather than counted as read.
Two enumerations, both exact sets so neither can absorb a new property
silently. `_INTERNAL_ROUTES` has three entries for what the snapshot cannot
express -- adapter dispatch, a fallback tier this fixture shadows, a
topology branch no producer reaches -- and fails the moment one of them
becomes observable after all. The baseline has 39 lines, one reason each,
and fails in both directions: an untriaged declaration and a resolved one
are equally loud.
39 is 44 from the gap inventory minus the five shed-forecast properties the
forecast sensors and their attributes just took. Each catch-up task now
deletes the lines it surfaces, so the burn-down is a diff rather than a
claim.
`mid.grid_state` joins RESIDUAL_EXEMPT_PATHS: the probe found the
`mid_grid_state` sensor reading a field enumerated nowhere, the same hole
`panel.dominant_power_source` was in.

Subject: [PATCH 049/345] feat(sensor): surface what the BESS reports about
itself
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
`meter/active-power` and `status/communication-state` have been declared and
published on the BESS device since r202633 and nothing read either. The battery's
own charge/discharge figure lands as a sensor enabled by default; its own link
health lands as a diagnostic, off by default, because a fault signal is
interesting when something is wrong and noise on a device card the rest of the
time.
**The sign was the whole problem, and it is now normalised in one direction.**
The two properties arrive in opposite conventions: the enclosure's
`power-flows/battery` is discharge-positive per the capability catalog, while its
meter of the BESS is charge-positive-negated — it meters the battery the way it
meters a circuit it feeds. `BATTERY_POWER_SENSOR` has always negated the first;
the library now negates the second into the snapshot's charge-positive frame, and
`bess_meter_power` passes that through. Both sensors sit on the same device card
and both read **positive when charging**. A sensor whose sign contradicted the
one beside it would be worse than no sensor, so the agreement is asserted on the
two states rather than inferred from the two definitions, at two operating points.
The charging premise itself is derived, not assumed: the four power flows balance
(`pv + battery + grid == site`, grid positive when importing), and solving that
identity says which way the battery is going without appealing to any convention
this codebase chose. Reading the direction off the sign would be circular, since
the sign is the claim under test.
**The README said the opposite** — "Battery Power ... (+discharge, -charge)" —
and had since before the v1.0 work. The shipped behaviour is charge-positive;
only the documentation was wrong, so the documentation is what changed.
`bess_meter_power` deliberately does not replace `battery_power`. One is the
enclosure's arbitrated figure and one is the battery's own meter; on a healthy
panel they agree, and where they disagree that is a fact worth seeing.
`bess_communication_state` likewise does not replace `bess_connected`: the binary
sensor is the panel's view of the link and the new sensor is the battery's, and a
BESS can report its own link lost while the enclosure still claims it.
`BESS_TELEMETRY_SENSORS` is a separate tuple from `BESS_METADATA_SENSORS` because
the creation rule differs. Every metadata sensor exists on any commissioned BESS,
filled or empty; these two come from capability nodes a BESS may not have, so
absence has to mean no entity rather than a permanently unknown one. Gated twice
like the shed forecast — `has_bess_telemetry` for the capability (a new
`detect_capabilities` member, so a firmware upgrade that adds the nodes reaches
the reload), then the description's own `value_fn` for the individual reading.
Both descriptions are `SCHEMA_CONDITIONAL_FIELD` *and* name their `field_path`,
per the rule Task 1b established: flat's BESS device class declares neither
property, so the both-adapters gate cannot be satisfied, but the entity still
needs its Repair mention and its unavailability. The paths join
`RESIDUAL_EXEMPT_PATHS` as `SCHEMA_1_ONLY`, which schema_1's metadata rows earn
them and which buys unit validation against the BESS's own `$description`.
Their two lines leave the unread baseline, which is what the burn-down looks
like: 39 to 37.
Tests read every expected value out of the capture and prove it by mutation.
Flipping the new sensor's sign fails five; removing the per-description creation
gate fails four; dropping either exemption fails seven across four modules.

### Added
+- **Your battery's own meter and its own link health, on panels running the v1.0 data model.** **Meter Power** is what the BESS itself reports it is charging or
+ discharging at, as distinct from the panel's **Battery Power**, which is the enclosure's arbitrated figure. Both have been on the wire since firmware r202633
+ and nothing read either. Meter Power is enabled by default; **Communication State** — the BESS's own `OK` / `DEGRADED` / `LOST` / `UNKNOWN` report on its link
+ — is a diagnostic and is off by default, since it is only interesting when something is wrong.
+- **Both battery power sensors read positive when the battery is charging.** They come off the wire in opposite sign conventions and are normalised to one, so
+ the two sitting side by side on the BESS device can never point opposite ways.
+- **Communication State is not the same thing as BESS Connected.** The binary sensor is the _panel's_ view of the link, from the enclosure's connection record;
+ the new sensor is the _battery's_ view of it. A BESS can report its own link lost while the panel still claims it, and now you can see that.
+- Both sensors are created only where the BESS publishes the reading behind them — a battery on the older data model, or one whose firmware publishes only one
+ of the two, gets no entity for what it cannot report rather than one permanently unknown, and a BESS that gains the capability on a firmware upgrade picks the
+ sensors up on the reload the integration already performs.
+
+### Fixed
+
+- **The README described Battery Power's sign backwards** (`+discharge, -charge`). The sensor has always reported charging as positive; only the documentation
+ was wrong. No entity changed.
+
- **Backup planning, in minutes: two new sensors on panels running the v1.0 data model.** **Time to Priority Shed** is how long before the panel starts shedding
circuits, and **Backup Time Remaining** is how long before the battery is spent. Your panel has been publishing both since firmware r202633 and nothing read
them; they are the numbers you would actually set an alarm on, so they are enabled by default and sit beside the power and energy sensors rather than under

+"""What the BESS reports about itself, surfaced as two sensors on its own device.
+
+`meter/active-power` and `status/communication-state` were declared, published
+and read by nobody. They are the battery's own view of its power and its own view
+of its link, as opposed to the enclosure's view of both.
+
+Every assertion runs against a real snapshot built by the real schema_1 adapter
+over the vendored capture, and every expected value is read out of that capture
+rather than written as a literal — a test that pins the same constant the code
+pins passes whether or not the wire is ever read. Each reading is proved by
+republishing it, deleting it, or dropping the node that carries it.
+
+**The sign is the hard part, and it is what most of this module is about.** The
+capture is of a *charging* battery, published as a negative `meter/active-power`
+because the enclosure meters the BESS the way it meters a circuit it feeds. The
+snapshot negates that into its charge-positive frame, and `battery_power` — the
+sensor already on this device, reading the enclosure's discharge-positive
+`power-flows/battery` — negates too. Two negations of two opposite wire
+conventions, landing on one convention in the UI. A sensor whose sign
+contradicted the one beside it would be worse than no sensor, so the agreement is
+asserted directly rather than inferred from the two definitions.

Subject: [PATCH 050/345] feat(sensor): surface the panel's power control
system
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
`energy.ebus.capability.pcs` 0.3 is the largest capability the enclosure
publishes — sixteen properties on the panel and two on every circuit — and
nothing read a byte of it. It is UL 3141 import limiting: the panel's Firm
Service Rating, plus the arbitration that reconciles every active import
constraint to one enforced current limit.
**The capability decides the entity/attribute split, not taste.** It says
outright that `pcs` does not re-publish the other regimes' constraints and that
"what `pcs` publishes is the **result**: the effective `import-limit` and the
`binding-constraint`". So the result is the entities: `pcs_import_limit` in amps,
enabled by default because a panel throttling the user's supply is a fact about
their electricity rather than about the integration's health, and
`pcs_binding_constraint` beside it, which is what makes the number
interpretable — "limited to 40 A" versus "limited to 40 A *because the utility
sent an envelope*". `pcs_active` is the third, a binary sensor, because it is the
only property here that changes on its own and therefore the one an automation
triggers on.
The twelve amps-native inputs and `pcs_enabled` ride as attributes on the limit
they explain. They are working, not readings: eleven of the thirteen move only
when somebody reconfigures the panel, and a dashboard with twelve near-constant
amperages on it is not a dashboard. Circuit-side `pcs/managed` and `pcs/priority`
land the same way, as two attributes on the circuit's power sensor — a 40-space
panel would otherwise gain eighty entities carrying two facts. `pcs_priority` is
deliberately not the existing `shed_priority`: two policies on one relay, and the
catalog keeps them apart because a circuit may take part in one, both, or
neither.
**Creation is gated once, on the node, and that is the one place this capability
differs from the shed forecast and the BESS telemetry.** Both of those gate a
second time on the reading, because a declared-but-unpublished property would
become a permanently-unknown entity. That reasoning does not transfer: every
`pcs` property is legally `0.0`, `false` or `UNCONFIGURED`, and the reference
capture is exactly that — a PCS which exists and is switched off. A per-reading
gate would create the entities on a configured panel and delete them the moment
somebody turned the PCS off, which is the state most panels are in and the state
a user most wants reported. The library carries the distinction as
`SpanPanelSnapshot.pcs is None`, from the capability's own rule that absence of
the node means the device runs no PCS, and `has_pcs` joins `detect_capabilities`
so a panel that gains the node reaches the reload.
All three descriptions are `SCHEMA_CONDITIONAL_FIELD` *and* name their
`field_path`: no flat panel declares the capability, so the both-adapters gate
cannot be satisfied, while the entities still need their Repair mention and their
unavailability. The three result paths join `RESIDUAL_EXEMPT_PATHS` as
`SCHEMA_1_ONLY`, which schema_1's metadata rows earn them and which buys the
limit unit validation against the panel's own `$description`; the fifteen
attribute reads join as `NEITHER`, matching the shed-forecast refinements.
Eighteen lines leave the unread baseline, 37 to 19 — the whole PCS block, panel
and circuit.
**The capture cannot prove a reading on its own, so no test asks it to.** All
sixteen panel values are zeros, `false` and `UNCONFIGURED`, which means an entity
wired to a neighbouring property reports the identical value and an entity
hardcoding a zero agrees with the wire by accident. Presence is asserted against
the capture; every reading is proved against a republished PCS where each value
differs from the captured one and from every sibling's, with the attribute
dictionary compared whole so a wrong wiring shows as a value under the wrong
name. On top of that, each of the sixteen is republished individually and exactly
one observable may move. Crossing two attribute families fails four tests; making
the presence gate value-based fails thirty; deleting the circuit attribute block
fails four; dropping one exemption fails three; pointing `pcs_active` at
`enabled` fails eight.

+publishes `energy.ebus.capability.pcs` at all, so the both-adapters gate cannot
+be satisfied; the paths are enumerated in `RESIDUAL_EXEMPT_PATHS` as
+`SCHEMA_1_ONLY`, which schema_1's metadata rows earn them and which buys
+`pcs_import_limit` unit validation against the panel's own `$description`.

+"""The Power Control System, surfaced as three entities and fifteen attributes.
+
+Thirteen of the attributes are on the effective-limit sensor and two are on
+every circuit's power sensor.
+
+`energy.ebus.capability.pcs` 0.3 is the largest capability the enclosure
+publishes — sixteen properties on the panel, two on every circuit — and nothing
+read a byte of it. The capability itself says what to surface: it reconciles
+every active import constraint to one enforced current limit, and "what `pcs`
+publishes is the **result**: the effective `import-limit` and the
+`binding-constraint`". So the result is the entities, and the arbitration behind
+it is their attributes.
+
+**The capture is a PCS that is switched off, and every test here is written
+around that.** Every limit is `0.0`, every enablement `UNCONFIGURED`, every
+boolean `false`. Uniform data makes an assertion cheap to satisfy for the wrong
+reason — an entity wired to the neighbouring property reports the identical
+value, and an entity hardcoding a zero agrees with the wire by accident. So no
+state or attribute here is asserted against the captured values. Presence is
+checked against the capture; every *reading* is proved by republishing a value
+that differs from the captured one and from every sibling's, and the sensor's
+whole attribute dictionary is compared at once, so a wrong wiring shows up as a
+value under the wrong name rather than as a value that happens to match.

Subject: [PATCH 051/345] test(pcs): pin that only one PCS sensor carries the
arbitration
The attribute set is carried on the description rather than decided from
`description.key` inside the entity, and nothing asserted the half of that claim
that matters: `pcs_binding_constraint` must publish no attributes at all while
`pcs_import_limit` publishes thirteen. Without it the default reader was the one
line of this feature no test reached.

Subject: [PATCH 052/345] feat(binary_sensor): surface the panel's link to each
DER it feeds
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
`bess_connected` has shown the enclosure's view of the link to the battery since
v1.0 landed. The identical fact for a solar inverter or a charger reached
nothing, and the reason is where the panel publishes it: `connection` 0.1 states
the enclosure/DER relationship on the **circuit**, so the battery's record
arrives on the upstream lugs — already read — while the inverter's and each
charger's arrive on the circuits that feed them, and that half of the capability
had no reader. One of three device classes had a link sensor because of where its
record happened to sit.
`pv_panel_link` and `evse_panel_link` close it. Connectivity, diagnostic, on the
device the link describes: the charger's on its own sub-device, the inverter's on
the panel beside `pv_vendor` and `pv_product` until the PV becomes a sub-device
of its own.
**The names are the point, not a detail.** `evse_ev_connected` sits two
definitions above the new charger sensor and reads `evse.status`: a vehicle is
plugged in. `evse_panel_link` reads the feeding circuit's connection record: the
enclosure can reach the charger. Those diverge exactly when it matters — a
charger mid-session behind a lost link reports a plugged-in vehicle and a dead
link at once, because the last session state the panel heard is still the last
session state the panel heard — and a test produces that state rather than
asserting the distinction in prose. `PLUG` against `CONNECTIVITY`, primary
against diagnostic, and neither key is a prefix of the other.
**Creation is gated on the record existing, never on the circuit.** The spec is
unambiguous: `connection.md` makes an unpublished property the "unknown" signal,
`distribution-enclosure.md` makes a mixed-load circuit publishing no `feeds-*`
normal, and the enum is `OK,LOST,DEGRADED` with no UNKNOWN member — so absence
is the only way a panel can say it does not know, and reporting it as a broken
link would invent the one reading a user would act on. Two of the capture's five
circuits publish nothing, and they create nothing. The gate is per DER, not per
panel: two chargers can be fed by two circuits of which only one publishes a
record, and only one sensor may exist then. `has_der_link_health` joins
`detect_capabilities` so a panel that starts publishing reaches the reload.
Both descriptions are `SCHEMA_CONDITIONAL_FIELD` *and* name their `field_path`:
flat firmware publishes `connected` on the BESS and on no other device class, so
the both-adapters gate cannot be satisfied, while the entities still need their
Repair mention and their unavailability. `pv.connected` and `evse.connected` join
`RESIDUAL_EXEMPT_PATHS` as `SCHEMA_1_ONLY`, which schema_1's metadata rows earn
them — `battery.connected` sits beside them as `SCHEMA_0_ONLY`, which is the
whole shape of the gap in one place.
One line leaves the unread baseline, 19 to 18:
`circuit/connection/feeds-device-status`. `feeds-device-type` stays, and its
recorded reason is still true — the library resolves a DER's class by
dereferencing `feeds-device-id` against the tree's declared `$type`, so the echo
is read by nothing and would be redundant if it were.
**The capture publishes `OK` on all three records, so no test rests on it.** That
value is satisfied by an implementation returning a constant, one reading the
wrong circuit, and one handing every DER the first record it finds. Every
expectation is read out of the capture, the enum's members come from the
circuit's own `$format`, and each reading is proved by republishing values that
differ per DER and then swapping them — two chargers are in the capture precisely
so cross-wiring is falsifiable. Conflating the charger's link with the EV plug
fails nine tests; removing the record gate fails four; making it a value gate
rather than a record gate fails five; landing both chargers' records on one
charger fails four; dropping one exemption fails three; restoring the baseline
line fails one.

Subject: [PATCH 053/345] fix(coordinator): derive capabilities once, so an
upgrade actually reloads
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
`_detect_capabilities` was a second, hand-rolled copy of the derivation the
platforms gate on. It knew four capabilities — bess, pv, power_flows, evse —
and `helpers.detect_capabilities` knows nine. `mid` had been missing since it
was added; this catch-up took the count to five, since `shed_forecast`,
`bess_telemetry`, `pcs` and `der_link_health` all joined the helper and none
joined the copy.
The copy is what `_check_capability_change` reads to decide whether to request
a reload. So a panel that gained any of the five on a firmware upgrade
published the properties, matched a creation gate that was never re-run, and
asked for no reload — the entities appeared only when the user next restarted
Home Assistant. Two of the commits in this branch claim the opposite in their
own messages, because the helper is where the capability was registered and
the copy is not visible from there.
Delegating removes the class of bug rather than the instance. `has_evse` gains
the circuit-typed-evse signal the copy carried and the helper lacked, so
converging loses nothing: creation still iterates `snapshot.evse`, so a
commissioned-but-not-yet-published charger adds no entities and only brings the
reload forward to the moment the panel first admits it exists.
The test asserts the two sets are equal on a capture that exercises the five
missing capabilities, rather than asserting the two names are the same object —
the latter would pass again the moment someone re-inlined the logic.

Subject: [PATCH 054/345] feat(sensor): give the panel its own identity, and
give the SSID back
The metadata sweep: no new entity classes, four surfaces, and one of them is a
regression rather than a feature.
`wifi_ssid` is the regression. Flat published it and this integration has shown
it as an attribute since; on v1.0 the library read nothing into the field, so an
upgrading user's attribute quietly emptied. With the library reading it, both
adapters produce `panel.wifi_ssid` and the producible gate refuses to let it
stay exempt -- `test_no_exempt_path_is_producible_by_both` named it and demanded
the promotion, which is the ratchet working as designed. It is declared on
`SpanPanelStatus`, the entity that reads it, so a Repair can name what a dead
field takes down.
The panel's device card now shows the manufacturer, model and hardware revision
the enclosure publishes. The fallbacks are the compatibility guarantee, not a
courtesy: flat declares none of the three, so every existing installation lands
on "Span" / "SPAN Panel" exactly as before, and `hw_version` is absent rather
than blank where no revision is published.
`shed/policy` reaches `dsm_state` as `shed_algorithm` plus the two SoC
thresholds -- the numbers that make the panel's shed behaviour predictable. An
algorithm this integration does not recognise keeps its name and carries the raw
document beside it, because the policy schema is versioned in its own `$id` and
a user can read a document a parser could not.
`evse.part_number` becomes a diagnostic sensor shaped like `bess_part_number`,
promoted out of the unread baseline by the schema_1 metadata row the library
gained.
Baseline: 18 -> 13. `pv/info/firmware-version` stays, reworded to name Task 7 --
the library reads it, but PV has no sub-device for a `sw_version` to land on
until that device exists. MID firmware needed nothing: `mid_device_info` has
carried `sw_version` and `hw_version` since the MID landed.
Fixtures resynced from the library, whose reference tree caught up with the
producer: eight identity properties it had never published are published now,
including the SSID this all turns on.

+Four surfaces, no new entity classes, and one of them is a regression rather

+the panel has published all along that nothing rendered, so a test asserting a
+constant the code also holds would pass whether or not the wire is ever read.

+than through the `DeviceInfo` dict, because the dict is what the code returns and
+the registry is what a user sees.
+
+**`panel.wifi_ssid` is the regression.** Flat published `core/wifi-ssid` and the
+integration has surfaced it as an attribute since; v1.0 declares
+`status/wifi-ssid`, schema_1 mapped nothing to it, and the path's exemption
+annotation said `SCHEMA_0_ONLY` -- which was true, and sanctioned a user losing
+an attribute on upgrade. With the library reading it, both adapters produce the

Subject: [PATCH 055/345] feat(number): give each charger the charge-current
limit its panel declares
The catch-up's only settable property, and the integration's first `number`
platform. One entity per commissioned EVSE, on the charger's own device card
beside the sensors it already has.
Every part of the control is described by the panel rather than by this
integration. The value and the maximum come from whichever node the charger's
`$description` declares -- `config/{max,user-max}-charge-current` in the
reference tree, `charge-limit/{installer-max,owner-limit}` in the eBus catalog,
resolved in the library so nothing here names a wire property. A charger
publishing the catalogued spelling produces an identical entity, asserted field
by field against one publishing SPAN's.
`native_max_value` is the installer-commissioned ceiling, read off the wire.
That is the whole reason this is not a hardcoded slider: the maximum is a
derating from the breaker and J1772, it moves when a charger is recommissioned,
and Home Assistant checks a service call against it before this platform sees
one. The library checks again against what the panel is publishing *now* and
refuses rather than clamping -- a clamp would report a limit the charger is not
enforcing.
Two gates, both from the declaration and neither from a value:
- `$settable` creates the entity. A charger publishing a perfectly readable
limit it does not declare writable gets no control, the same distinction
`never-backup` already draws for a circuit's priority. Asserted through
`async_setup_entry`, because an entity that must not exist cannot be observed
by asking an entity for its state.
- An unpublished ceiling makes the entity unavailable. A number must report some
maximum and Home Assistant's default is 100, so the alternative is putting a
plausible-looking amperage in front of a user that no installer commissioned.
A write the panel has acknowledged and not yet applied shows as a
`charge_current_limit_target` attribute while the state stays the limit the
charger is still enforcing -- the rendering the priority select already gives
`circuit.priority_target`, rather than a second pending-command mechanism.
Field paths: the limit and the ceiling are `SCHEMA_1_ONLY` -- schema_1 resolves
a metadata row for each from the charger's own `$description`, and flat's `evse`
type declares no settable ceiling at all -- and the description is
`SCHEMA_CONDITIONAL_FIELD` naming the limit, so the entity keeps its Repair
mention and its unavailability. `$settable` and the `$target` echo are `NEITHER`:
facts about a command rather than readings.
The two `evse/config/*` lines leave the unread baseline, 13 -> 11.
Proof, beyond the assertions: nine deliberate breakages of this platform and its
gates -- the creation gate ignoring `$settable`, a hardcoded maximum, the value
reading the ceiling, the write addressing the wrong charger, the refusal
swallowed, the platform unforwarded -- each failed the tests that name it, and
dropping either read from `RESIDUAL_EXEMPT_PATHS` put its property straight back
into the unread baseline.

### Added
+- **A charge-current limit you can set, on panels running the v1.0 data model.** Each commissioned SPAN Drive gets an **EVSE Charge Current Limit** number on
+ its own device — the ceiling the charger offers your vehicle, which you can lower to charge more slowly and raise back. It is the first control this
+ integration has that changes something on a charger rather than on the panel.
+- The maximum you can ask for is the one your installer commissioned, read from the panel rather than assumed: the box will not accept a value above the
+ charger's rated current, and neither will anything else — a value beyond it is refused before it is sent, not quietly rounded down to something you did not
+ ask for. If the panel has not yet published what the charger is rated for, the control reports unavailable instead of offering an invented range.
+- The control appears only where the panel says the limit can be changed. A charger that publishes its limit as read-only gets no control, which is the same
+ distinction **Circuit Priority** already makes for a circuit commissioned never-backup.
+- While the panel is acknowledging a change it has not yet applied, the requested value shows as a `charge_current_limit_target` attribute and the state stays
+ the limit the charger is still enforcing — the same way Circuit Priority reports a priority change in flight.
+
- **Whether your panel can reach your solar inverter and each of your chargers, on panels running the v1.0 data model.** **PV Panel Link** and **EVSE Panel
Link** are the same fact **BESS Connected** has always shown for the battery: the panel's own report of the link to a device it feeds. The battery's version
worked because the panel publishes it on the main lugs; the inverter's and each charger's are published by the circuit that feeds them, and nothing read that

+"""Number entities for the Span Panel — today, one per commissioned EV charger.
+
+The charge-current ceiling is the only settable property v1.0 puts outside the
+panel and its circuits, and the only control this integration has ever offered
+that carries a physical bound: the installer commissions a maximum from the
+breaker rating and J1772 derating, and nothing a user does may exceed it.
+
+So every number this platform builds is described by the panel rather than by
+this module. The value, the maximum, and the fact that a control exists at all
+come from the charger's own `$description`, resolved in the library
+(`span_panel_api_schema_1.charge_limit`) because the node carrying the limit has
+two spellings in circulation and the `$description` is the specification's
+authority on which one a charger publishes. Nothing here names a wire property.
+
+**A control is offered only where the panel declares one.** `$settable` on the
+limit is what creates the entity; the commissioned ceiling is what bounds it.
+A charger that declares neither gets no entity, which is the honest rendering of
+`charge-limit.md`'s absence semantics — "the EVSE has no adjustable
+charge-current ceiling (it charges at a fixed rate)".
+
+**A pending write shows as an attribute, not as a state.** The panel echoes an
+accepted command on the Homie `$target` topic and republishes the property when
+it takes effect, and the priority select already renders that pair exactly this
+way (`circuit.priority_target`). Reporting the requested value as the state
+instead would show a limit the charger may never have accepted.

+"""The EVSE charge-current limit, as the integration's first number entity.
+
+The only settable property the v1.0 catch-up surfaces, so this is the one place
+in the catch-up where being wrong reaches the panel rather than the dashboard.
+The tests are shaped around that.
+
+**Nothing here names an amperage.** Every expectation is computed from the
+capture, and where the capture publishes the same value on both chargers — it
+publishes 32 on each — the test republishes differing values first, because an
+assertion satisfied by reading one charger twice proves nothing about two.
+
+**The write is proved to the wire, not to a mock.** `test_the_write_reaches_the
+_wire_as_one_publish` drives the entity through the real client and the real
+schema_1 adapter and asserts the exact topic and payload the transport hands the
+broker — including that the topic is addressed by the charger's *device id*
+while the entity holds its serial-harmonised snapshot key, which are different
+strings and would both look plausible in a log.
+
+**The control exists only where the panel declares it.** `$settable` is the
+gate, so a charger whose limit is not declared settable gets no entity at all —
+asserted through `async_setup_entry`, because an entity that must not exist
+cannot be observed by asking an entity for its state.

Subject: [PATCH 056/345] feat(device): give the solar inverter a card of its
own, and move its entities to it
PV was the last DER on a v1.0 panel with no device. Its vendor, model and
nameplate capacity were rendered as three diagnostic sensors on the *panel's*
card -- beside the panel's own manufacturer and model, so the card whose job is
saying which enclosure this is read as if the enclosure were an Enphase
inverter. The firmware version the library has read all along reached nothing,
because a version has nowhere to go but a card; `pv/info/firmware-version` was
baselined saying exactly that, and that line goes.
`SUB_DEVICE_PV` and `pv_device_info` follow the BESS and the MID, and the four
kinds now sit under one classifier: `classify_sub_device_identifier` tests the
EVSE *infix* before the three suffixes, because a suffix rule cannot tell a
charger whose node id ends in `_pv` from an inverter.
The identifier is `{panel serial}_pv` and deliberately does not mention the
inverter's serial. Every PV description declares `info/serial-number` and no
producer publishes one; an identifier preferring it would change the day
firmware started publishing, and a device identifier is what a consumer keys its
registry on -- so that day would read as the inverter being replaced. The serial
stays baselined, with the reason reworded to name this second thing that would
have moved.
Five entities change device: `pv_power`, `pv_vendor`, `pv_product`,
`pv_nameplate_capacity` and `pv_panel_link`. Home Assistant re-homes an entity
itself when it re-registers with new `device_info`, so there is no bespoke
migration and deliberately none written. What it does not do is re-derive an
`entity_id`, and it derives a new one from the *device* name -- so a fresh
installation would have landed on `sensor.span_panel_solar_pv_vendor` where
every existing one has `sensor.span_panel_pv_vendor`, two shapes for the same
entity decided by install date. `construct_panel_scoped_entity_id` pins the
panel-scoped id on both, which is what `construct_single_circuit_entity_id`
already does for the circuit sensors that live on an EVSE.
`tests/test_pv_device.py` seeds a registry in the released shape, sets both
platforms up through real entity platforms, and reads the registry back: every
entity keeps its `entity_id` and its `unique_id`, lands on the inverter, and
leaves no duplicate or orphan behind. A fresh install is compared against a
migrated one on a second Home Assistant instance and must match entity for
entity. A user-renamed `entity_id` still wins over the pin.

+PV was the last DER on a v1.0 panel with no card. Its vendor, model and

+device — beside the panel's own manufacturer and model, so a panel card read as
+if the enclosure were an Enphase inverter — and the firmware version the library
+has always read reached nothing at all, because a version has nowhere to go but
+a card. `pv/info/firmware-version` was baselined naming exactly that.
+
+**The identifier is the decision worth writing down.** `{panel serial}_pv`, and
+deliberately not the inverter's serial. Every PV `$description` declares

+preferred a serial would be `_pv` on every panel today and
+`_` on the first panel whose firmware starts publishing one — and
+a device identifier is what a consumer keys its registry on, so that day would
+read as the inverter being replaced. `test_a_serial_arriving_on_the_wire_does_not_move_the_device`
+produces that day and asserts nothing moves.
+
+**The migration is the risk.** Existing installations have these entities on the
+panel device with panel-scoped `unique_id`s and panel-scoped `entity_id`s. Moving
+an entity to another device must change *only* the device: a changed `entity_id`
+breaks a dashboard, a changed `unique_id` orphans the entity and mints a
+duplicate. Home Assistant re-homes an entity by itself when it re-registers with
+new `device_info`, which is the mechanism used here; what it does *not* do is
+re-derive an `entity_id`, so a fresh installation would otherwise get
+`sensor.span_panel_solar_pv_vendor` where every existing one has
+`sensor.span_panel_pv_vendor`. `construct_panel_scoped_entity_id` pins that shut
+and `test_a_fresh_install_and_a_migrated_one_are_the_same_shape` is the proof.
+
+Every expectation about what the card shows is read out of the vendored capture
+and proved by republishing or unpublishing the property, never by a literal. The

Subject: [PATCH 057/345] docs(changelog): record the two catch-up tasks that
shipped without an entry
The metadata sweep and the PV sub-device landed with commit messages and no
user-facing changelog, and the capability-reload fix landed with neither. The
changelog is what a user reads to decide whether an upgrade affects them, so a
restored attribute and a reload that did not happen belong in it more than most
of what is already there.
Two of the four are fixes rather than additions, and are written as such: the
SSID emptied silently when a panel upgraded, and a panel that gained a
capability while Home Assistant was running created no entities and asked for
no reload. Both are the kind of thing a user cannot report usefully, because
nothing appears in a log and the symptom is an absence.

+
+- **Your panel's own card now shows what the panel says it is** — manufacturer, model and hardware revision, read from the enclosure rather than assumed. A

+ blank where no revision is published.

+- **Circuit Priority's shed policy is readable.** The `dsm_state` sensor gains `shed_algorithm` and the two state-of-charge thresholds that decide when circuits
+ shed and when they come back — the numbers that make the panel's shed behaviour predictable rather than surprising. A policy this integration does not
+ recognise keeps its name and carries the panel's raw document beside it, so you can read what a parser could not.

integration has that changes something on a charger rather than on the panel.

### Fixed
+- **The Wi-Fi network name came back.** Panels on the older data model report the SSID they are joined to, and this integration has shown it as an attribute on
+ the panel status sensor for as long as it has existed. On the v1.0 data model nothing read it, so the attribute quietly emptied when your panel upgraded — a
+ value you had, silently gone, with no error and nothing in the log. It is read again.
+- **A firmware upgrade that adds a capability now actually reloads.** The check that decides whether new hardware warrants a reload knew about four capabilities
+ where the rest of the integration knew about nine. A panel that gained the shed forecast, the power control system, battery telemetry or DER link health while
+ Home Assistant was running published the data, matched every rule for creating the entities, and asked for no reload — so the new entities appeared only the
+ next time you restarted. This affected the Microgrid Interconnect Device before this release too.
+
- **The README described Battery Power's sign backwards** (`+discharge, -charge`). The sensor has always reported charging as positive; only the documentation
was wrong. No entity changed.

Subject: [PATCH 058/345] Revert "feat(device): give the solar inverter a card
of its own, and move its entities to it"
This reverts 85ca619. The change moved four PV entities off the panel device
onto a new sub-device, and the brief that asked for it was wrong about who has
those entities.
`create_power_flow_sensors` gates PV on `has_pv()`, which is schema-agnostic,
and schema_0 populates PV vendor, model and nameplate capacity. So every
existing installation with solar has `pv_vendor`, `pv_product`,
`pv_nameplate_capacity` and `pv_power` on its panel device *today*, on current
firmware. The move was scoped as a v1.0 gap; it would have reached the whole
installed base on an integration update, with no firmware change involved.
Entity ids, unique ids and history survived a re-home -- that much was built
and proved. What does not survive is everything keyed on the device: an entity
with no explicit area inherits its device's area, so PV entities in a panel
assigned to an area would have fallen out of it and stopped matching
area-based automations and filters, and any dashboard card populated from the
panel device would have lost its PV rows.
Adding sensors cannot break an installation. Moving existing entities between
devices can, and this bought nothing but consistency with the BESS and the
charger. `pv/info/firmware-version` returns to the unread baseline, which is
the honest state: the library reads it and no card carries it.

Subject: [PATCH 059/345] feat(device): give the solar inverter a card of its
own
Reinstates 85ca619 without the part of it that was wrong.
PV was the last DER on a v1.0 panel with no device. eBus models it as a device
beside the BESS, the MID and the EVSE, and it was the only one of the four with
nothing to render on. Its vendor, model and nameplate capacity were three
diagnostic sensors on the *panel's* card, beside the panel's own manufacturer
and model, so the card whose job is saying which enclosure this is read as if
the enclosure were an Enphase inverter. The firmware version the library has
read all along reached nothing, because a version has nowhere to go but a card;
`pv/info/firmware-version` was baselined saying exactly that, and that line
goes. `pv/info/serial-number` stays, with its reason intact.
`SUB_DEVICE_PV` and `pv_device_info` follow the BESS and the MID, carrying
manufacturer, model and sw_version off the wire. The identifier is
`{panel serial}_pv` and deliberately does not mention the inverter's serial:
every PV description declares `info/serial-number` and no producer publishes
one, so an identifier preferring it would change the day firmware started
publishing, and a device identifier is what a consumer keys its registry on --
that day would read as the inverter being replaced. The four kinds now sit
under one classifier, which tests the EVSE *infix* before the three suffixes
because a suffix rule cannot tell a charger whose node id ends in `_pv` from an
inverter.
Five entities change device: `pv_power`, `pv_vendor`, `pv_product`,
`pv_nameplate_capacity` and `pv_panel_link`. Circuit entities do not move, the
PV circuit's included -- those belong to the circuit model.
**What is different from 85ca619.** That revision pinned all five to their
panel-scoped `entity_id` on every installation, so a new install matched an
upgraded one exactly. The pin is gone. `async_get_or_create` honours a suggested
object id only at first registration -- for a `unique_id` it already knows it
returns the existing entry, updates `device_id` and leaves `entity_id` alone --
so the pin never protected the installed base at all. All it did was give every
future installation an entity id derived from the panel rather than from the
device the entity sits on, permanently, to match a history that installation
does not have. So an existing installation keeps `sensor.span_panel_pv_vendor`
and a new one gets `sensor.span_panel_solar_pv_vendor`, both correct, and
`construct_panel_scoped_entity_id` and the `entity_id_override` parameters that
existed only to serve the pin are removed. `construct_single_circuit_entity_id`
is untouched -- it serves the circuit sensors on an EVSE sub-device and is not
this.
No area is seeded on the new device: `suggested_area` is deprecated with
`breaks_in_ha_version="2026.9"` against a 2026.8 pin, and an explicit registry
write cannot tell an area a user cleared from one never assigned, so it would
re-assign the card on every reload. The reasoning is recorded on
`pv_device_info` rather than left to be rediscovered.
`tests/test_pv_device.py` seeds a registry in the released shape with literal
legacy ids, sets both platforms up through real entity platforms, and reads the
registry back: every entity keeps its `entity_id` and its `unique_id`, lands on
the inverter, and leaves no duplicate or orphan behind. A user-renamed
`entity_id` still wins. `test_a_fresh_install_and_a_migrated_one_differ_only_in_entity_id`
replaces the test that asserted the two were identical: it pins both sets of
literals, asserts the five have the same unique_ids and the same device across
the fork, and asserts every *other* entity is identical between the two -- and
its docstring says why the asymmetry exists, so it is not read later as a bug.

### Added
+- **Your solar inverter gets a device of its own, on panels running the v1.0 data model.** Its vendor, model and nameplate capacity used to render as diagnostic
+ sensors on the _panel's_ card, beside the panel's own manufacturer and model — so the card whose job is telling you which enclosure this is read as though the
+ enclosure were an Enphase inverter. It now has a card like the battery and the chargers already do, carrying the firmware version the panel has been
+ publishing all along.
+- **If you already have these sensors, nothing about them changes.** The five entities that move to the new card — PV Power, PV Vendor, PV Product, PV Nameplate
+ Capacity and PV Panel Link — keep the entity ids and unique ids they have today, so dashboards, automations and history follow them across untouched. Only the
+ card they appear on changes.
+- **New installations get different entity ids for these five, and that is intended.** Home Assistant derives a new entity's id from the name of the device it
+ sits on, so a system installed from now on gets `sensor.span_panel_solar_pv_vendor` where a system installed before this release keeps
+ `sensor.span_panel_pv_vendor`. Both are correct and neither will change again: an existing system must never have an id renamed under it, and a new one gets
+ the id Home Assistant would give it. If you are comparing two SPAN systems and their PV entity ids differ, install date is why. The unique ids are the same on
+ both, and both sets of entities sit on the same new card.

- **Your panel's own card now shows what the panel says it is** — manufacturer, model and hardware revision, read from the enclosure rather than assumed. A
panel on the older data model publishes none of the three and keeps exactly the card it has today; the hardware revision row is left off rather than shown
blank where no revision is published.

+"""The solar inverter gets a device of its own, and takes its entities with it.
+
+PV was the last DER on a v1.0 panel with no card. Its vendor, model and
+nameplate capacity were rendered as three diagnostic sensors on the *panel's*
+device — beside the panel's own manufacturer and model, so a panel card read as
+if the enclosure were an Enphase inverter — and the firmware version the library
+has always read reached nothing at all, because a version has nowhere to go but
+a card. `pv/info/firmware-version` was baselined naming exactly that.
+
+**The identifier is the decision worth writing down.** `{panel serial}_pv`, and
+deliberately not the inverter's serial. Every PV `$description` declares
+`info/serial-number` and no producer publishes one, so an identifier that
+preferred a serial would be `_pv` on every panel today and
+`_` on the first panel whose firmware starts publishing one — and
+a device identifier is what a consumer keys its registry on, so that day would
+read as the inverter being replaced. `test_a_serial_arriving_on_the_wire_does_not_move_the_device`
+produces that day and asserts nothing moves.
+
+**The migration is the risk.** Existing installations have these entities on the
+panel device with panel-scoped `unique_id`s and panel-scoped `entity_id`s. Moving
+an entity to another device must change *only* the device: a changed `entity_id`
+breaks a dashboard, a changed `unique_id` orphans the entity and mints a
+duplicate. Home Assistant re-homes an entity by itself when it re-registers with
+new `device_info` — `async_get_or_create` returns the entry it already holds for
+a `unique_id`, updates its `device_id` and leaves its `entity_id` untouched — so
+there is no bespoke migration here and deliberately none written.
+
+**The fork in entity ids is deliberate; do not close it.** Nothing pins an
+`entity_id`. Home Assistant derives a new entity's object id from the name of the
+device it belongs to, so a fresh installation gets
+`sensor.span_panel_solar_pv_vendor` where every existing one keeps
+`sensor.span_panel_pv_vendor`. Both are correct: an existing installation must
+never have an id change under it, and a new one gets the standard Home Assistant
+assignment rather than a legacy shape invented to match history it does not have.
+An earlier revision pinned the panel-scoped id on both to keep the two identical;
+that was reversed, because the pin bought uniformity by giving every future
+installation an entity id derived from the wrong device.
+`test_a_fresh_install_and_a_migrated_one_differ_only_in_entity_id` is the record
+of the decision.
+
+Every expectation about what the card shows is read out of the vendored capture
+and proved by republishing or unpublishing the property, never by a literal. The
+registry-shape expectations *are* literals, on purpose: they record what a
+released installation carries, and deriving them from the code under test would
+make the migration assertions vacuous.

Subject: [PATCH 060/345] fix(strings): say what the new-entity count actually
counts
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The notice reads "1 new entity/entities have appeared for your SPAN Panel",
which scans as a total. It is not: the notice only ever reports entities
created with `entity_registry_enabled_default=False`, because those are the
ones that reach the user through nothing at all. Everything added enabled --
the shed-forecast sensors, the PCS entities, the battery meter -- announces
itself by appearing, and is deliberately outside the count. A user who reads
"1" after an upgrade that added a dozen entities concludes the upgrade did
almost nothing.
The count now follows a label that names its scope, and a second sentence says
what it excludes.
`entity/entities` goes at the same time, along with `entidad(es)`,
`entité(s)` and `entidade(s)` in the three Latin locales. The parenthetical is
there because the string has to read for one or many, and Home Assistant's
issue translations have no plural forms. Putting the number after a label --
"Entities affected: 3" -- removes the agreement problem instead of papering
over it, and removes it in every language rather than only in English. Japanese
never had the problem, since it counts with 個 and does not inflect; it gains
only the scope sentence.

Subject: [PATCH 061/345] feat(binary_sensor): put the Wi-Fi network name on
the Wi-Fi link
`wifi_ssid` has been an attribute of the Software Version sensor since the
integration existed, for the historical reason that `panel_size` was already
squatting in that attribute block. A network name on a firmware-version sensor
is incoherent. The coherent host is the Wi-Fi Link binary sensor: both values
come off the same node on the wire -- `status/wifi` and `status/wifi-ssid` on
v1.0, `core/wifi` and `core/wifi-ssid` on flat -- and the entity that reports
whether Wi-Fi is up is the one that should report which network it is up on.
It stays on the Software Version sensor as well. That copy is what a user's
`state_attr('sensor.span_panel_software_version', 'wifi_ssid')` template reads,
and a template reading a missing attribute returns None rather than erroring, so
moving it would break those silently. One duplicated attribute string is the
price; the old location comes out at a future major version.
The Wi-Fi Link gets an entity class of its own rather than a branch on
`SpanPanelBinarySensor`. `_residual_field_paths` is a `ClassVar` and that base
class serves every panel binary sensor -- door, both links, panel status, PCS
activity, PV link -- so declaring `panel.wifi_ssid` there would claim all six
read the SSID. That is not cosmetic: the declaration is what a Repair consults
to name the entities a dead field took down with it, so an unresolved SSID would
name the door sensor. Which class serves which description is a named map keyed
by description key, so the setup comprehension goes on saying only "one entity
per description".
Two classes now declare one residual path, which the apparatus was built for and
is now verified: `residual_field_paths()` unions a frozenset and the coordinator
maps a path to a set of entity ids, so the Repair names both readers.
`residual_field_paths()` also imports `binary_sensor` now -- the subclass walk
sees only imported modules, and the path being declared twice is exactly what
would have hidden the omission.
No exemption counts move: `panel.wifi_ssid` was already a declared residual
rather than an entry in `RESIDUAL_EXEMPT_PATHS`.

Subject: [PATCH 062/345] refactor(sensor): move the Wi-Fi network name rather
than duplicate it
The previous commit left `wifi_ssid` on the Software Version sensor as well,
on the argument that a `state_attr('sensor.span_panel_software_version',
'wifi_ssid')` template must keep working. That argument does not survive
checking: at v2.0.8 `STATUS_SENSORS` held four descriptions -- `dsm_state`,
`dsm_grid_state`, `current_run_config`, `software_version` -- so the attribute
appeared on all four. The other three have since moved to
`SpanPanelDataSensorEntityDescription` / `SpanPanelPanelStatus`, which narrowed
it to one sensor without anyone recording that it had happened. This finishes
that narrowing and writes it down instead of restoring half of it.
So the SSID is on the Wi-Fi Link binary sensor and nowhere else. `panel_size` is
untouched. The residual declaration moved with the read: it is what a Repair
consults to name the entity a dead field took down with it, and a copy left on a
sensor that no longer reads the field would name the wrong entity.
That leaves `panel.wifi_ssid` declared only in `binary_sensor`, which made the
subclass walk's import list load-bearing for the first time -- and nothing held
that list to anything. `test_source_residuals_match_the_subclass_walk` cannot:
under pytest every platform module is imported many times over for other
reasons, so an omission still walks and the test passes. Dropping `binary_sensor`
from the list was a green mutation. It is now pinned in both directions against
the modules the source scan finds declarations in, which also caught `sensor_panel`
becoming a stale entry the moment its declaration left.
Tests that asserted the attribute on Software Version now assert its absence,
against a snapshot that does publish an SSID so a restored read fails rather
than passing on a panel that carries none.

+ the Wi-Fi Link binary sensor instead. `panel_size` is unaffected and stays where it is.
### Fixed
- **The Wi-Fi network name came back.** Panels on the older data model report the SSID they are joined to, and this integration has shown it as an attribute on

Subject: [PATCH 063/345] docs(developer): explain the declared-but-unread gate
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The gate is new and its mechanism is not obvious from reading it: it decides
"read" by experiment rather than by inspecting a map, republishing each declared
property with a legal different value and checking whether anything a consumer
reads moved. That is why it sees consumption `_PROPERTY_FIELD_MAP` cannot
express, and it is worth writing down before someone reads the map and concludes
the gate is redundant.
Also states the two limits, because both are easy to mistake for coverage. The
gate reads the vendored fixture, so it cannot see a property a real panel starts
publishing in the field. And it asks whether anything moved, not whether
everything did — a property read on the first PV child and discarded on the
second still counts as read.

+## Knowing what the panel publishes that nothing reads
+
+The panel declares more than this integration surfaces, and the gap is tracked mechanically rather than by memory.
+
+### The gate
+
+`tests/test_declared_but_unread.py` asserts that **every property declared in a device's `$description`** is one of three things: mapped to a snapshot field by
+an adapter, consumed by a known internal route (topology, dispatch, device_info, role resolution), or listed in
+`tests/fixtures/unread_declarations_baseline.json` with a one-line reason.
+
+It decides "read" **by experiment**, not by inspecting a map. For each declared property it republishes a legal different value derived from the property's own
+`datatype`/`format`, rebuilds the snapshot through the real adapter, and checks whether any field a consumer reads actually moved. That is why it sees
+consumption the `_PROPERTY_FIELD_MAP` cannot express, and why it caught a case where a metadata row existed while nothing read the value.
+
+It fails in **both** directions:
+
+- A newly declared property that reaches nothing fails the build until somebody triages it.
+- A property that becomes read fails until its baseline line is deleted.
+
+### Working with the baseline
+
+When you surface a property, delete its baseline line in the same change. The test will tell you if you deleted one you did not surface, or surfaced one whose
+line you left.
+
+When you decide a property should _stay_ unread, add a line with an honest reason. The reasons are load-bearing — they are what stops the file becoming a list
+of things nobody remembers deciding. The current entries are all permanent: deliberate skips (`status/postal-code` copies location into recorder history; Home
+Assistant owns `status/time-zone`), values held for identity reasons (`pv/info/serial-number`), redundant echoes (`connection/*-device-type` dereferences to a
+declared `$type`), and properties no producer publishes (`connection/count`).
+
+### What it does not cover
+
+The gate reads the **vendored fixture**, so it answers "what does our capture declare that we do not read". It cannot see a property a real panel starts
+publishing in the field. That is the purpose of the runtime discovery work on `feat/discovery-and-catalog-validation`: the same question asked of a live panel
+and surfaced in diagnostics, so a maintainer triaging an issue can see what that fleet declares that this integration ignores.
+
+Note also that a property can be _read on one device and not another_ and the gate will not see it — it asks whether anything moved, not whether everything did.
+`snapshot.pv` keeps the first `energy.ebus.device.pv` child and discards the rest, so a second inverter is invisible while the property still counts as read.

Subject: [PATCH 064/345] feat(diagnostics): carry what the panel declares and
this integration ignores
`test_declared_but_unread` answers "what does our capture declare that we do not
read" by experiment, and it is fixture-bound: a real panel that starts
publishing a property fails nothing until somebody recaptures. schema_1 now asks
the same question of the live tree and returns the answer as namespaced rows in
its metadata map. This is the consumer half.
**The partition comes first, because a discovery feature that breaks the
catch-up's gate is a net loss.** `schema_validation.partition` splits an
adapter's map on the `discovered.` namespace before any other question is asked
of it, and every inventory downstream -- the producible gate, `unread`, the
exemption annotations, the unit vocabulary -- sees the curated half only. All of
them read "in an adapter's map" as "this integration could read this", which a
discovered path is not: one landing in `unread` would bury ten deliberate
entries under whatever a firmware release added, and would make the count depend
on the panel in front of the user. `test_the_unread_inventory_is_deaf_to_
discovery` proves it by mutation -- a synthetic discovered row moves `unread`,
`unresolved` and the unit mismatches not at all. The test fixtures follow the
same rule, so no other module can be perturbed by accident.
**Diagnostics ships paths, datatypes, units and retention -- never values.**
`TO_REDACT` is key-based over the config entry: it knows nothing about wire
property names and could not protect a value added here, so the block is safe by
construction rather than by redaction. The row shape is a `TypedDict` so a fifth
key is a type error rather than a review comment, and the privacy claim is
asserted against the capture's own published values.
Nothing user-facing: no entity, no Repair, no notification. That line is the
one between this and automatic adoption, whose costs -- notice aggregation, an
exclusion denylist, the accumulator register -- are unsettled, and
`test_the_discovery_block_creates_nothing_a_user_sees` holds it.
**Pointed at the library worktree this branch belongs with.** `[tool.uv.sources]`
named `-p2`, which has neither half of this change, so the branch was being
tested against a library four commits behind it. Repointing at `-p3` surfaced a
stale annotation the conformance gate caught immediately and correctly:
`pv.software_version` is `SCHEMA_0_ONLY`, not `NEITHER`. It was annotated on the
claim that flat's `pv` device class declares no firmware version; flat declares
`software-version` on it, and the library grew the mapping row once a producer
valued the v1.0 half. The exemption stands -- schema_1 still carries no row,
because a version string is identity rather than a reading -- but the reason it
stands has changed.
Against the vendored tree the report is nine properties, which is the ten-entry
unread baseline less `circuit/breaker/poles`, whose value the library does read.

Note also that a property can be _read on one device and not another_ and the gate will not see it — it asks whether anything moved, not whether everything did.
`snapshot.pv` keeps the first `energy.ebus.device.pv` child and discards the rest, so a second inverter is invisible while the property still counts as read.
+### The runtime half: what the panel in front of the user declares
+
+The schema_1 adapter asks the same question of the live tree and puts the answer in **diagnostics**, under `schema_discovery`:
+
+```json
+"schema_discovery": {
+ "available": true,
+ "count": 9,
+ "properties": [
+ { "path": "discovered.circuit/connection/count", "datatype": "integer", "unit": null, "retained": false },
+ { "path": "discovered.distribution-enclosure/status/postal-code", "datatype": "string", "unit": null, "retained": true }
+ ]
+}
+```
+
+`available: false` means the adapter has not reported metadata yet — a real state on a reconnect, and not the same as an empty report. `retained` says whether
+the panel has published a value for the property, which is the declared-but-never-valued signal; it never says what the value is.
+
+**Paths, datatypes, units and retention only — never values.** Diagnostics leave the house into issues and forum posts, and `TO_REDACT` in `diagnostics.py` is
+key-based over the config entry: it knows nothing about wire property names and could not protect a value added here. `test_schema_discovery` asserts that
+against the capture's own published values rather than leaving it to review.
+
+This is **maintainer-facing only**. Nothing creates an entity, a Repair or a notification from it. Automatic adoption is a separate, unbuilt step whose costs —
+notice aggregation, an exclusion denylist, the accumulator register — are not settled.
+
+### Why discovered rows cannot reach the curated inventories
+
+The adapter returns both kinds of row in one map, keyed by the library's `discovered.` namespace. `schema_validation.partition` splits them **before any other
+question is asked**, and everything downstream — the producible gate, the `unread` inventory, the exemption annotations, the unit vocabulary — sees the curated
+half only.
+
+That partition is load-bearing rather than tidy. Every one of those inventories reads "in an adapter's map" as "this integration could read this", which a
+discovered path is not: a discovered row in `unread` would bury ten deliberate entries under whatever a firmware release added, and would make the count depend
+on the panel in front of the user. `test_the_unread_inventory_is_deaf_to_discovery` proves it by mutation — a synthetic discovered row changes `unread`,
+`unresolved` and the unit mismatches not at all.
+
+The test fixtures follow the same rule: `adapter_fixtures.schema_one_metadata()` hands out the curated half, and a test that wants the other half asks for
+`schema_one_discovery()` by name.
+
+### Keeping the library's answer honest
+
+The adapter decides "read" from four enumerations of what it addresses — the metadata map, the lugs direction tables, the charge-limit resolution, and
+`_CONSUMED_WITHOUT_A_ROW` for the properties it reads into the snapshot without a unit surface. A stale entry there fails _silently_, by keeping a property out
+of the report. `tests/test_schema_one_discovery.py` in the library runs the same republish-and-diff experiment this gate uses and holds every entry to it in
+both directions, so the report means "nothing reads this" rather than "nobody wrote it down".

+"""What the panel declares that nothing here reads, surfaced to a maintainer.
+
+`test_declared_but_unread` asks this question of the vendored capture and
+answers it by experiment. It is the right check and it is fixture-bound: a real
+panel that starts publishing a property fails nothing until somebody recaptures.
+The adapter answers the same question at runtime, for the panel in front of the
+user, and this module is the consumer half — the partition that keeps those rows
+out of every curated inventory, and the diagnostics block that carries them to
+whoever is triaging the issue.
+
+Two properties are load-bearing and both are asserted here rather than reviewed:
+
+**The partition.** Discovered rows arrive in the same map as curated ones. Every
+inventory downstream — the producible gate, the unread set, the exemption
+annotations, the unit vocabulary — reads "in an adapter's map" as "this
+integration could read this", which a discovered path is not. One namespace test
+applied once is what keeps that true, and `test_the_unread_inventory_is_deaf_to
+_discovery` is the mutation proof that it is applied.
+
+**No value leaves.** A diagnostics payload goes into GitHub issues and forum
+posts. `TO_REDACT` is key-based over the config entry and knows nothing about
+wire property names, so nothing downstream can protect a value put in this
+block. It carries declarations only, and that is checked against the capture's

Subject: [PATCH 065/345] feat(adoption): surface devices this integration
models nothing for
The panel is a hub for whatever plugs into it and the eBus schema is
vendor-extensible, so a device type nobody modelled is an expected arrival.
It used to produce no device, no entity and no sign it was there.
Adoption is scoped to a device. A new property on a modelled device stays a
curation task, because that is where the judgement lives about entity versus
attribute versus device-card field, and adopting it would spend an entity_id
permanently on a machine-derived shape before anyone made that call.
No adopted entity carries a state_class. It is not derivable from the wire,
a wrong one corrupts long-term statistics irreversibly, and enrolling
properties nobody asked for is a permanent write to every recorder database.
A user who wants statistics wraps the entity themselves.
info resolves to the device card and connection to the device link, keyed on
the node rather than on property names because the catalogs carry no marker
for a device reference.
An adopted device freezes its identity anchor at first sighting, with the
registry as the memory: a late serial, or a wire id that moves when a serial
appears, would otherwise read as a device replacement.
The notice counts an adopted device rather than listing its entities, and
diagnostics carry declarations and never values.
Controls are classified and not yet built: a generic property write would put
a new member on SchemaAdapter, required of every adapter package. Diagnostics
count what is waiting on it.

### Added
+- **A device the panel publishes that this integration has never modelled now appears, instead of appearing nowhere.** SPAN positions the panel as the hub for
+ whatever plugs into it and the eBus schema is explicitly vendor-extensible, so a device type nobody modelled is an expected arrival — and until now it
+ produced no device, no entity and no sign it was there. Such a device now gets a card of its own hanging off the panel, carrying whatever `info` it publishes,
+ with its readings as entities beneath it. Everything adopted arrives **disabled and diagnostic**: nothing reaches a dashboard uninvited, and the new-entity
+ notice names the device so you can find it.
+- **Devices this integration does model are left alone, deliberately.** A new property on a circuit, the battery, a charger or the panel is not adopted — it is
+ curated in a release, because that is where the judgement lives about whether it should be an entity, an attribute, or a line on a device card. Automatic
+ adoption would spend an `entity_id` permanently on a machine-derived shape before anyone made that call. The sixteen Power Control System properties that
+ curation collapsed into one entity and thirteen attributes are the worked example of what a rule cannot produce.
+- **Nothing adopted enters long-term statistics, and that is a decision rather than an omission.** No adopted entity carries a `state_class`. It is not declared
+ on the wire and cannot be derived from one — this integration ships `feedthroughEnergyProducedWh` as `TOTAL` beside `mainMeterEnergyProducedWh` as
+ `TOTAL_INCREASING`, same unit and same device class — and a wrong one writes corrupt statistics that fixing the panel afterwards does not repair. Enrolling a
+ property nobody asked for into long-term statistics is also a permanent write to your recorder database. If you want statistics from an adopted reading, wrap
+ it in a template sensor, a Riemann-sum integration or a utility meter: that is your call, made on an entity you chose to enable.
+- **`info` becomes the device card and `connection` becomes the device link — neither becomes entities.** A panel publishing its own build metadata and its own
+ wiring topology should not arrive as a handful of sensors holding version strings and opaque device ids. The split is keyed on the Homie node rather than on
+ property names, because the capability catalogs carry no marker for "this value is a device reference" and a hard-coded name list goes stale silently.
+- **An adopted device keeps the identity it was first seen under.** A serial number arriving after the device was adopted is recorded on its card and moves
+ nothing, and a device adopted under its serial survives its wire id changing. Either move would read to Home Assistant as a device _replacement_ and would
+ take the device's entities and their history with it.
+- **The new-entity notice counts an adopted device rather than listing its entities.** A vendor device declaring a dozen properties would otherwise spend the
+ whole notice on itself and teach you that the category is noise — which would cost you the curated additions too.
+- **Diagnostics report which device types and properties were adopted, and never their values.** The same rule the declared-but-unread report follows: a
+ diagnostics attachment leaves the house, and the redaction that protects your config entry is key-based and knows nothing about wire property names.
+- **Controls are classified but not yet built.** A property the panel accepts writes to is recognised as a switch, a select or a number, and surfaces as a
+ reading until the write path exists — every write this integration performs today goes through a curated, adapter-named topic, and a generic one is a change
+ to the adapter contract with its own version bump. Diagnostics count how many properties are waiting on it, so the decision is made on a measurement.
+
- **Your solar inverter gets a device of its own, on panels running the v1.0 data model.** Its vendor, model and nameplate capacity used to render as diagnostic
sensors on the _panel's_ card, beside the panel's own manufacturer and model — so the card whose job is telling you which enclosure this is read as though the
enclosure were an Enphase inverter. It now has a card like the battery and the chargers already do, carrying the firmware version the panel has been

+"""Entities for devices the panel publishes and this integration models nothing for.
+
+The panel is a hub for whatever plugs into it, and the eBus schema is explicitly
+vendor-extensible. A device type this integration has never modelled therefore
+arrives as an expected event rather than a hypothetical one -- and until now it
+arrived as nothing at all: no device, no entity, no sign it was there.
+
+**The unit of adoption is a device, never a property.** A new property on a device
+this integration already models is a curation task with a short turnaround, and
+minting an entity for it automatically would spend an `entity_id` permanently on
+a shape a human would likely have chosen differently. That cost only bites where
+curation is coming. On a device type nobody has modelled, no better identity is
+coming, so a disabled diagnostic entity is strictly better than the silence.
+
+**Nothing adopted enters long-term statistics.** No adopted entity carries a
+`state_class`, ever. Three reasons, and the third is the one that shapes the
+module: `state_class` is not declared on the wire and is not derivable from one
+(`feedthroughEnergyProducedWh` is `TOTAL` beside `mainMeterEnergyProducedWh` as
+`TOTAL_INCREASING` -- same unit, same device class); a wrong one writes corrupt
+statistics that fixing the producer does not repair; and enrolling a property
+nobody asked for into long-term statistics is a permanent write to every
+install's recorder database. A user who wants statistics from an adopted reading
+can wrap it in a template sensor, a Riemann sum or a utility meter, which is
+their call to make on an entity they chose to enable.
+
+**These entities declare no field paths.** `snapshot.adopted_devices` is outside
+the curated field-path vocabulary by construction: it carries no metadata row, so
+the producible gate has nothing to check it against and `residual_field_paths()`
+must not collect it. That is why this module is absent from that walk's import
+list, and why the classes below declare no `_residual_field_paths`.

### Why discovered rows cannot reach the curated inventories
@@ -245,6 +245,111 @@ The adapter decides "read" from four enumerations of what it addresses — the m
of the report. `tests/test_schema_one_discovery.py` in the library runs the same republish-and-diff experiment this gate uses and holds every entry to it in
both directions, so the report means "nothing reads this" rather than "nobody wrote it down".
+## Adopting a device this integration models nothing for
+
+The section above is about properties on devices we already read. This one is about a device type nobody modelled at all — a vendor's generator, heat pump or
+second inverter, which the eBus schema explicitly permits. Such a device used to produce nothing: no device, no entity, no sign it was there.
+
+### The rule
+
+**The unit of adoption is a device, never a property.**
+
+| What arrives | What happens |
+| ------------------------------------------------ | -------------------------------------------------------------------------------- |
+| A device type `MODELLED_TYPES` does not name | **Adopt.** One sub-device, its properties surfaced beneath it. |
+| A new node or property on a device we _do_ model | **Do not adopt.** It lands in `schema_discovery`; curate it in the next release. |
+| A new property on a device already adopted | Adopt, with its siblings. |
+
+The asymmetry is where the cost calculus actually points. An adopted entity's id is machine-derived and permanent once it registers, which is only a loss where
+curation is coming. On a type nobody modelled, no better id is coming and the alternative is silence.
+
+Extra instances of a modelled type are **not** adopted. A second BESS is a multiplicity limitation of the snapshot model, not an unmodelled device, and adopting
+it would stand a machine-named card beside the curated Battery describing the same hardware. The gap stays visible as a gap.
+
+### Inside an adopted device, the node decides the destination
+
+Keyed on the Homie node — what the eBus vocabulary defines — rather than on property names:
+
+- **`info/*` → device-card fields.** `model`, `serial-number`, `firmware-version`, `hardware-version`, `vendor-name`. The whole node, not just the five the card
+ reads: dropping only the recognised ones would surface `info/nominal-power` as a string sensor the moment a vendor declared one.
+- **`connection/*` → the device link.** Topology, which is `via_device`.
+- **Everything else → entities**, `EntityCategory.DIAGNOSTIC` and disabled by default.
+
+Why by node: the capability catalogs carry **no marker** for "this value is a device reference", so the only alternative is a hard-coded property-name list —
+and such a list goes stale silently. `ebus-sdk`'s own `topology.py` covers `feeds-device-id` and `fed-by-device-id` and omits `grid-forming-entity`, which lives
+on the `grid` capability. A node cannot go stale that way.
+
+### Nothing adopted enters long-term statistics
+
+No adopted entity carries a `state_class`. `test_no_state_class_is_set_anywhere_in_the_module` reads `adoption.py` as syntax and fails if one ever appears.
+
+Three reasons, and they are independent:
+
+1. It is not declared on the wire and is not derivable from one. This integration ships `feedthroughEnergyProducedWh` as `TOTAL` beside
+ `mainMeterEnergyProducedWh` as `TOTAL_INCREASING` — same unit, same device class, opposite classification.
+2. A wrong one writes corrupt long-term statistics, and fixing the producer afterwards does not repair them.
+3. Enrolling a property nobody asked for into long-term statistics is a permanent write to every install's recorder database.
+
+A user who wants statistics from an adopted reading wraps it in a template sensor, a Riemann-sum integration or a utility meter. That is their call, made on an
+entity they chose to enable.
+
+`device_class` is enumerated in `DEVICE_CLASS_BY_UNIT` rather than inferred. A unit outside the map gets **no** device class — `%` is deliberately absent,
+because its uses here are a state of charge, a confidence and a duty cycle, and no single class is right for all of them.
+
+### Identity freezes at first sighting
+
+`resolve_identifier` looks up **both** candidate spellings — `{panel serial}_adopted_{wire id}` and `{panel serial}_adopted_{serial}` — before minting either,
+and keeps whichever already exists. Both drift in practice:
+
+- a serial arriving _after_ adoption would move the device off its wire id, and
+- a producer that derives its wire id from a serial moves the id itself when the serial appears, which is why this repository holds PV's `info/serial-number`
+ unvalued.
+
+Either move reads to Home Assistant as a device **replacement**, taking the entities and their history. The device registry is the memory, so this needs no new
+persistence.
+
+`classify_sub_device_identifier` returns `None` for any identifier carrying the `adopted` token, tested before its suffix rules — the anchor is vendor
+vocabulary, and a device id ending in `pv` would otherwise classify as the panel's solar sub-device.
+
+### Controls are classified but not built
+
+`classify` implements the full rule, including the three control platforms:
+
+| Declaration | Platform |
+| ---------------------------------- | --------------- |
+| `boolean`, settable | `SWITCH` |
+| `boolean` | `BINARY_SENSOR` |
+| `enum`, settable, with a `format` | `SELECT` |
+| numeric, settable, with a `format` | `NUMBER` |
+| anything else | `SENSOR` |
+
+A settable property with no `format` falls back to a reading because `format` is the value domain: a select with no option list and a number with no bounds are
+broken controls, not safe ones.
+
+The three control platforms are in `CONTROL_PLATFORMS` and are **not constructed yet**. Every write this integration performs goes through a curated,
+adapter-named topic, and a generic property write would put a new member on `SchemaAdapter` — whose required set is derived from the protocol itself, so it
+would be required of every adapter package and would invalidate built adapter wheels. That is a contract change with its own version bump.
+
+`adopted_control_count` reports how many declared properties are waiting on it, in diagnostics under `adopted_devices.pending_controls`, so the decision is made
+on a measurement rather than a guess.
+
+### The notice counts devices, not entities
+
+Adopted entities are disabled, so they reach the user only through `async_notice_new_disabled_entities`. That notice lists curated additions individually and
+collapses each adopted device to one line with a count — `Backup Generator (6 entities)`. A vendor device declaring a dozen properties would otherwise spend the
+whole notice on itself and teach the user that the category is noise, which would cost them the curated additions too.
+
+### Diagnostics
+
+`adopted_devices` in the diagnostics payload carries the device type, model, property paths, datatypes, units, `settable` flags and the platform each would
+take. **No values, no device name, no serial.** Same rule as `schema_discovery` and for the same reason: `TO_REDACT` is key-based over the config entry and
+cannot protect a wire value put there.
+
+### Adopted entities declare no field paths
+
+`snapshot.adopted_devices` is outside the curated field-path vocabulary by construction — it carries no metadata row, so the producible gate has nothing to
+check it against. `adoption.py` is therefore absent from `residual_field_paths()`'s import list, and its entity classes declare no `_residual_field_paths`.

Subject: [PATCH 067/345] feat(adoption): build the controls, authorised by the
snapshot not by arguments
A settable property on an adopted device now becomes a switch, a select or a
number rather than surfacing as a reading. Disabled and diagnostic like every
other adopted entity, so a control exists only where a user enables one.
The write goes through set_adopted_property, which resolves the property
against the current snapshot's adopted devices and publishes to the set topic
that property carries. No topic is accepted from the caller.
The alternative considered and rejected was a set_property_topic member on
SchemaAdapter. It would have put every curated control one argument away, and
two of them do real work on the way out: the islanding assertion translates
its value, and the charge ceiling refuses one above the commissioned limit. It
would also have been required of every adapter package, so an install with an
older adapter wheel would fail at discovery rather than losing one feature.
All five creators share one partition function so classify stays the only
place a platform is decided, asserted as a partition rather than per platform.
Nothing is translated or clamped on the way out. The declaration is all this
integration knows about an adopted property, and a NUMBER on an integer
property publishes 45 rather than 45.0.

+broken controls, not safe ones. A settable `boolean` needs none — its datatype states the domain in full.
-The three control platforms are in `CONTROL_PLATFORMS` and are **not constructed yet**. Every write this integration performs goes through a curated,
-adapter-named topic, and a generic property write would put a new member on `SchemaAdapter` — whose required set is derived from the protocol itself, so it
-would be required of every adapter package and would invalidate built adapter wheels. That is a contract change with its own version bump.
+All five creators share `_create`, so `classify` is the only place a property's platform is decided. `test_every_property_reaches_exactly_one_platform` asserts
+that as a partition, which is what five separate predicates could not guarantee.
-`adopted_control_count` reports how many declared properties are waiting on it, in diagnostics under `adopted_devices.pending_controls`, so the decision is made
-on a measurement rather than a guess.
+Controls are disabled and diagnostic like every other adopted entity. There is deliberately no second, weaker gate — no read-only mode for settable properties.
+Enabling an entity is a deliberate act, commanding it is a second one, the panel authorises the write regardless of what we create, and this integration already
+ships switches that open and close breakers.
+
+### The write, and why it is not a generic one
+
+`SpanMqttClient.set_adopted_property(device_id, node_id, property_id, value)` publishes the write. **The lookup is the authorisation**: it resolves the property
+against the current snapshot's `adopted_devices` and publishes to the `set_topic` that property carries. No topic is accepted from the caller.
+
+That matters because the obvious alternative — a `set_property_topic(device, node, property)` member on `SchemaAdapter` — would put every curated control one
+argument away, and two of them do real work on the way out:
+
+- `set_dominant_power_source` translates `GRID` into the `ON_GRID` the v1.0 islanding assertion accepts.
+- `set_evse_charge_limit` **refuses** a value above the commissioned ceiling, because publishing past it is the one write with a physical consequence.
+
+A generic write reachable at modelled devices routes around both. Because `set_topic` is populated only for settable properties on devices `is_modelled`
+rejected, a modelled device produces no `AdoptedDevice` and cannot be addressed this way however the arguments are spelled.
+
+It also kept the change additive. A new `SchemaAdapter` member is required of every adapter package, so an install carrying an older adapter wheel would fail at
+**discovery** — the whole integration, not one feature.
+
+No payload translation and no bounds check on the way out, deliberately: the library knows nothing about an adopted property beyond its declaration, and
+inventing a bound would be inventing a fact about somebody's hardware. The entity constrains the value to the declared domain and the panel stays the authority
+on whether to accept it. A `NUMBER` on an `integer` property publishes `45`, never `45.0`.
+
+Diagnostics report `adopted_devices.controls` — how many adopted properties write back rather than only reporting.

Subject: [PATCH 068/345] feat(additions): announce added entities in a
notification that names them
Two problems with the previous new-entity notice.
It covered only entities added disabled, on the reasoning that an enabled one
is already visible in the entity list and its history. Nobody watches their
entity count, so that made every enabled addition invisible.
And it derived the diff from setup timing -- the registry before the platforms
against the registry after -- which answers correctly exactly once. On the
next startup the entity is already registered beforehand and the diff is empty
by construction, so anything not announced in that one window never was. What
is announced is now recorded in a Store, so the question is whether the user
has been told rather than whether it happened seconds ago.
It is a notification rather than a Repair because an addition is not a repair:
nothing is broken and nothing needs fixing. The retired issue is deleted at
setup, since it was raised is_persistent and would otherwise stand forever
with nothing left to re-derive it.
Translations are read from this component's own translations directory. The
Home Assistant helper filters to the categories it defines and a persistent
notification is not one of them -- a custom category loads as nothing, which
was verified rather than assumed.
Separately: adopted devices are now registered explicitly, before the
platforms. A vendor device publishing only an info node resolves entirely to
its device card, creates no entity, and so had nothing to create it -- it
produced no device, no entity and no notification at all.

### Added
+- **New entities are now announced in a notification that names them — whether or not they arrived switched on.** Previously only entities added _disabled_ were
+ mentioned, on the reasoning that an enabled one is already visible in your entity list and its history. That is only true if you are watching your entity
+ list, which nobody is: an addition that breaks nothing was indistinguishable from no addition at all. The notification names every entity that was added,
+ splits them by whether they are ready to use or still switched off, and tells you where to turn the switched-off ones on.
+- **It is a notification rather than a Repair, because an addition is not a repair.** Nothing is broken and nothing needs fixing. Any new-entity item still
+ sitting in your Repairs list from a previous version is removed on upgrade.
+- **And it can no longer be missed by a restart landing in the wrong place.** The old notice compared the entity registry before and after startup, which
+ answers correctly exactly once — on the next startup the entity is already registered and the comparison is empty. What has been announced is now recorded, so
+ the question is whether you have been told rather than whether it happened in the last few seconds. It stays quiet on a first install, and quiet once more on
+ the first startup after this change, so upgrading does not announce a release's worth of history.
+- **An adopted device now appears even when it publishes no readings at all.** A device that advertises what it is — its vendor, model and firmware — before
+ publishing any measurement resolves entirely to its device card, so it created no entities, and because devices were created as a side effect of entity
+ creation it produced nothing whatsoever: no device, no entity, no notification. It is now registered in its own right.
+

- * It is never reconciled away. `async_sync_schema_issues` deletes the defect
- ids it does not re-derive, and applying that here would delete this notice
- on the very next startup. Its reconcile scope is `_DEFECT_PREFIXES`, which
- deliberately does not include this one.
- * Raising is skipped outright when the id already exists. What that buys is
- narrow and worth stating exactly: a repeat of the same set cannot rewrite
- the text of a notice the user has already read. Without it the repeat would
- take `async_get_or_create`'s update branch, which replaces the placeholders
- — so a set that came back with a renamed entity would silently restate
- itself. It buys nothing against duplication, which the shared id already
- rules out.
-
- Severity is the mildest Home Assistant offers. `IssueSeverity` has no
- informational member — it is CRITICAL, ERROR, WARNING — so WARNING is the

-### The notice counts devices, not entities
+### Telling the user what was added
+
+Additions are announced by `additions.async_announce_new_entities` as a **persistent notification**, not a Repair. An addition is not a repair: nothing is
+broken and nothing needs fixing, and filing it under Repairs puts it in a category whose whole meaning is "something went wrong". The retired
+`new_entities_disabled` issue is deleted at setup by `async_clear_retired_new_entity_notices`, because it was raised `is_persistent` and would otherwise stand
+forever on an upgraded install with nothing left to re-derive it.
+
+Three things it does that the Repair did not:
+
+- **Enabled additions are announced too.** The old notice covered only `disabled_by=INTEGRATION`, reasoning that an enabled entity is already visible in the
+ entity list and its history. Nobody watches their entity count, so that reasoning made every enabled addition invisible.
+- **It names every entity**, rather than a count plus three examples. "What exactly was added" means all of it.
+- **The record is durable.** The old diff compared the registry before the platforms against the registry after, which answers correctly exactly once — on the
+ next startup the entity is already registered beforehand and the diff is empty by construction. `additions` records what it announced in a `Store`, so the
+ question is "has this been announced" rather than "was this registered in the last few seconds".
+
+It stays silent on a first install, and silent once more on the first run after this mechanism ships: an install predating the record has entities that were
+never announced but are not new either, so the first pass adopts them as known.
+
+Adopted devices are collapsed to one line with a count — `Backup Generator (6 entities)` — for the reason the whole design is device-scoped: a vendor device
+declaring a dozen properties would otherwise spend the entire notification on itself and teach the user to skip it, costing them the curated additions in the
+same message.
-Adopted entities are disabled, so they reach the user only through `async_notice_new_disabled_entities`. That notice lists curated additions individually and
-collapses each adopted device to one line with a count — `Backup Generator (6 entities)`. A vendor device declaring a dozen properties would otherwise spend the
-whole notice on itself and teach the user that the category is noise, which would cost them the curated additions too.
+**Translations are read from this component's own `translations/` directory**, not through `homeassistant.helpers.translation`. That helper filters to the
+categories Home Assistant defines, and a persistent notification is not one of them — a custom category loads as nothing at all, which was verified rather than
+assumed. The strings live under a `notifications` key in `strings.json` and all five locales, with English constants in `additions._FALLBACK` so an unreadable
+file costs the translation and not the notification.

Subject: [PATCH 069/345] fix(adoption): build adopted unique ids in the
integration's own grammar
The adopted id lower-cased and de-hyphenated the whole string, which mangled
the panel serial: span_sp3_242424_001_... where every curated id in the
integration says span_sp3-242424-001_.... A reader that parses an id by
position, as extract_circuit_uuid_from_unique_id does, would have met a second
grammar.
Now built through id_builder's own suffix helper, so an adopted id is
span_{serial}_adopted_{anchor}_{suffix} -- the same span_{serial}_{scope}_
{suffix} shape as every other. Only the node and property are de-hyphenated,
because that segment has to read like a curated suffix; the serial and the
anchor keep their hyphens, as a curated id keeps the serial's.
Uniform grammar does not remove the migration promotion needs, and a test says
so: curation changes the scope and the suffix, which is the change itself
rather than a formatting difference.

Subject: [PATCH 070/345] test(id_builder): close the suffix mappings against
silent id moves
The three suffix dictionaries translate legacy camelCase description keys into
the suffixes their entities have carried since before 2.0.8. That suffix is
shared by the unique_id and the entity_id, so an edit moves both on every
installed panel: the unique_id costs the long-term statistics and the
entity_id breaks the user's templates.
Adding an entry was the live hazard, because it silently reroutes a key that
previously resolved verbatim. The dictionaries are now held to their exact
contents, so an added key, a removed key and a changed value all fail --
verified by mutating each rather than by inspection.
The rule for anything new is verbatim, which the sub-device builders already
follow: their keys were written snake_case and never needed translating.
This also settles going verbatim across the board. A unique_id-only migration
would not cost statistics, since those key on the entity_id it preserves --
but because the suffix is shared, verbatim everywhere would force either
verbatim entity_ids, breaking every user reference, or decoupling the two and
losing the consistency the helper exists to provide.

Subject: [PATCH 071/345] feat(adoption): report whether an adopted device is
proxied by a peer
The library now carries the proxy link an adopted device declares. Diagnostics
report it as a boolean and never as the parent's id: a device id can embed a
serial, since producers derive a DER's id preferring a serial over a default
slug, so reporting the parent verbatim would leak the serial the block
deliberately withholds.
No topology changes. Every adopted device is still registered under the panel,
as every curated sub-device is. The nesting waits on python-sdk#57, where the
graph builder is still to be reconciled against the new DeviceTreeBuilder.

Running it before the platforms also makes the identity freeze single-valued: `resolve_identifier` runs once, at registration, so every entity created

+### The proxy link is recorded, and the nesting is not built
+
+`AdoptedDevice` carries `parent` (the device id it declares as its parent) and `proxied` (whether that parent is a peer rather than the tree root). Adoption
+does not act on either: every adopted device is registered under the panel with `via_device_id`, exactly as every curated sub-device is.
+
+They are carried because a _proxied_ unmodelled device is a real shape we would otherwise flatten away without leaving evidence. The library's own reference
+tree contains one — `bess-mid` declares `parent: bess`, which is the `{proxier-id}-{proxied-id}` naming of the specification's `devices/proxy.md`. A vendor
+gateway proxying its own sub-devices arrives the same way, and the parent link is the only structural information about how they relate.
+
+**Diagnostics report `proxied`, never `parent`.** A device id can embed a serial — producers derive a DER's id preferring a serial over a default slug, which is
+why the library holds PV's `info/serial-number` unvalued — so reporting the parent verbatim would leak the serial the block deliberately withholds. The boolean
+answers a maintainer's actual question, which is whether a proxied unmodelled device has appeared at all.
+
+**Why the nesting waits.** [python-sdk#49](https://github.com/electrification-bus/python-sdk/issues/49#issuecomment-5359203067) settled that proxied ids differ
+by design — several enclosures on a shared broker each proxying the same physical device produce different ids on purpose — and that consumers correlate by
+`info/serial-number`, never by device id. It also records that `ebus-sdk` 0.21.0 shipped `DeviceSpec` and `DeviceTreeBuilder`
+([python-sdk#57](https://github.com/electrification-bus/python-sdk/issues/57)), with the existing graph builder still to be reconciled against it. The tree
+model is under active reshaping upstream, so the fields capture the evidence and the topology waits.
+
+That comment also strengthens two things already here. Its deferral mechanism — a `device_id` callable returning `None` defers the device until
+`resolve_deferred()` — is the producer-side form of settling identity _before_ a device exists, which is what registering adopted devices ahead of the platforms
+does from this end. And "there is deliberately no existence predicate … expressing it by not calling `add()` is right" is the rule the capability gates already
+follow: presence in the tree is the signal, and there is no flag to consult.

Subject: [PATCH 072/345] fix(sensors): disable the five unreliable panel
readings, withdraw the sixth
The eBus maintainer's r202633 conformance note names six properties this
integration surfaces. Five shipped in 2.0.8; one never shipped. That decides
the remedy for each.
Disabled by default: feedthrough produced/consumed energy (the difference of
two unrelated counters, non-monotonic, ~whole-panel figures where the truth is
zero), feedthrough power (inverted relative to every other enclosure terminal),
and both downstream currents (they report the upstream service conductors).
Disabled rather than removed because an existing install has them with history
and entities must not vanish.
This helps nobody who already has them, and the comments say so:
entity_registry_enabled_default applies at first registration only, so an
existing install keeps them enabled. It stops new installs adopting them.
Withdrawn: bess_meter_power. It was added in the v1.0 work and never released,
so no install carries it and dropping it is free -- it would not be after a
release. Shipping it disabled would mean shipping a new entity known to be
inverted on real firmware, whose wrongness a user cannot detect: both signs are
plausible and the two topics are numerically identical. The reading it provided
is not lost, since battery_power reads power-flows/battery, which the note
confirms is correct as published.
Restore it when the firmware publishes the specified frame. The condition is on
BESS_TELEMETRY_SENSORS, the assumption is named in the library's devices.py,
and the wire property stays in the unread baseline with that reason.

### Added
+### Changed
+
+- **Five panel sensors are switched off for new installations, because the eBus specification's own maintainer has documented that their values cannot be relied
+ on.** A conformance note for SPAN firmware r202633 identifies three defects in what the panel publishes, all of which predate that release: the feedthrough
+ (downstream lugs) energy registers are computed from two unrelated counters and can decrease or go negative — on a panel with no feedthrough load they report
+ roughly whole-panel figures where the truth is zero — the feedthrough power reading is inverted relative to every other terminal, and the feedthrough currents
+ report the _upstream_ service conductors rather than a downstream measurement. The affected entities are **Feedthrough Produced Energy**, **Feedthrough
+ Consumed Energy**, **Feedthrough Power**, and the two **Downstream** current sensors.
+- **If you already have those five, nothing changes and they stay exactly where they are.** Home Assistant consults the enabled-by-default setting only when an
+ entity is first created, so an existing installation keeps them, keeps its history and keeps its entity IDs. This stops new installations picking them up; it
+ cannot reach back. If you use any of the five on a dashboard or in an automation, they are worth removing — but that is your decision to make, not something
+ an upgrade should do to you.
+- **Your other panel readings are unaffected.** The upstream lugs, the main panel meter and every circuit are in the correct frame. So is the power-flow group,
+ which the specification has now been corrected to describe the way the panel has always published it.
+
- **Diagnostics now say whether an adopted device is proxied by another device rather than by the panel.** Reported as a yes/no, never as the parent's
identifier: a device identifier can contain a serial number, and diagnostics deliberately carry no serials.

+The eBus maintainer's r202633 conformance note (2026-08-20) established that the

+charge-positive where the specification requires discharge-positive, and
+`build_battery`'s `_charge_positive()` negates on the assumption that the
+specification holds — so `battery.power_w` inverts on that firmware. The note
+calls this the one divergence a consumer cannot detect on its own: both signs

+
+Nothing here can catch it either. `ebus-panel-sim` 0.6.0 fixed the same

Subject: [PATCH 073/345] fix(sensors): restore bess_meter_power, withdrawn on
a premise the capture disproves
It was pulled on the conformance note's claim that ebus-panel-sim 0.6.0 fixed
the simulator's BESS meter/active-power, "so on that one property the simulator
is now correct where the panel is not" -- which would have made the defect
untestable here and the sensor knowingly wrong.
The capture that arrived with the note says otherwise, and so does the
maintainer's own comparison report beside it. Both emitter variants publish
power-flows/battery and bess meter/active-power at -3500.0: aligned, not
opposed, which is the panel's behaviour. distribution-enclosure-simulator#39
aligned them deliberately, because shipping firmware publishes the two that way.
So the two wire properties carry the same sign as each other on both producers,
each path negates once, and bess_meter_power cannot disagree with battery_power.
The reason for withdrawing it does not survive contact with the data.
Also settled: nothing regressed across the flat -> parent/child migration. Both
adapters map the same five downstream-lugs properties to the same fields with no
transform, and BATTERY_POWER_SENSOR is behaviourally identical to the one
released in 2.0.8. The five disabled sensors were wrong before the migration and
are wrong after it; they are not an upgrade regression.
The direction the shared battery convention runs is left open rather than
guessed. The docstring's charge-positive claim is withdrawn, not replaced: the
vendored fixture predates #39 and carries the pre-fix frame, and the only live
capture has the battery idle at 100 percent SoC with both properties zero.

which the specification has now been corrected to describe the way the panel has always published it.

-It read `battery.power_w`, the BESS child's own `meter/active-power`, alongside
-`battery_power` reading the enclosure's `power-flows/battery` — two views of one
-quantity, so that a disagreement between them would be visible rather than
-hidden behind a single entity.
-
-The eBus maintainer's r202633 conformance note (2026-08-20) established that the
-two will disagree *systematically* on a real panel, for a firmware reason rather
-than a panel-health one. The BESS child publishes `meter/active-power`
-charge-positive where the specification requires discharge-positive, and
-`build_battery`'s `_charge_positive()` negates on the assumption that the
-specification holds — so `battery.power_w` inverts on that firmware. The note
-calls this the one divergence a consumer cannot detect on its own: both signs
-are physically plausible and the two topics are numerically identical, so
-nothing in the tree contradicts itself observably.
-
-Nothing here can catch it either. `ebus-panel-sim` 0.6.0 fixed the same
-inversion in the simulator, so on this one property the simulator is now correct
-where the panel is not, and every test in this repository runs against the
-simulator.
-
-Withdrawn rather than compensated, and rather than shipped documented, for the
-reason the timing allows: this description had never been released, so no
-install carries the entity and no history is at stake. Dropping it now is free.
-Once a release creates it, the rule that an existing install's entities cannot
-simply disappear makes the same decision expensive.
-
-**Restore it when the firmware publishes the specified frame.** The correct
-reading is already shipped and unaffected — `battery_power` reads
-`power-flows/battery`, which the note confirms is correct as published — so
-nothing is lost meanwhile except the ability to compare the two. The wire
-property stays in `tests/fixtures/unread_declarations_baseline.json` with that
-reason, which is what will fail when somebody surfaces it again without
-revisiting this.
+**Power is enabled by default and not diagnostic; communication state is
+neither.** The battery's own charge/discharge figure is a reading a user graphs
+and automates on. Its link health is a fault signal, so it lands the way the
+other diagnostics do, off by default.
+
+**`bess_meter_power` is not `battery_power`, and the names say so.** The existing
+`battery_power` sensor reads `panel.power_flow_battery`, the enclosure's own
+arbitrated flow figure; this one reads the BESS's `meter/active-power`, the
+battery's own meter.
+
+**They agree, and this is why.** Both wire properties carry the *same* sign as
+each other -- a live panel capture and `ebus-panel-sim` 0.6.0 both publish
+`-3500.0` for the pair -- and each path applies exactly one negation, so the two
+entities land on one convention whatever that convention is. A sensor whose sign
+contradicted the one beside it would be worse than no sensor, and the agreement
+is structural rather than lucky.
+
+**Which direction that shared convention runs is not settled, and this docstring
+used to claim it was.** It said charge-positive. Working it through against
+`ebus-panel-sim` 0.6.0 -- where the four power-flow terms sum to zero and the
+identity forces the battery to be *discharging* at 3500 W -- both sensors read
+`+3500`, which is discharge-positive. The claim is withdrawn rather than
+replaced, because the sample that would settle it does not exist yet: the only
+live capture has the battery idle at 100 percent SoC with both properties
+exactly zero.
+
+**What is settled is that nothing here regressed.** `BATTERY_POWER_SENSOR` is
+behaviourally identical to the one released in 2.0.8 -- same source, same single
+negation, same device and state class -- and both adapters pass
+`power_flow_battery` through untouched. Whatever a live panel showed then, it
+shows now. `bess_meter_power` was briefly withdrawn on the belief that it would
+disagree with its neighbour on real firmware; the capture showed the two wire
+properties aligned on the panel *and* on the emitter, so it cannot, and it is
+restored.
+
+**The one thing still worth building** is a discriminator, because the alignment
+above is the eBus specification's *violation* rather than its rule: the spec
+defines `power-flows/battery` as the negation of the BESS meter. Comparing the
+two properties therefore tells a consumer which firmware it is talking to --
+identical means today's, opposed means a future conformant one -- which is what
+would let `battery.power_w` stay correct across that change without a release.
+Undecidable while the battery is idle and both read zero.
**`derived` as well as `field_path`, by the producible rule.** The gate wants a
path both adapters produce, and flat's BESS device class declares neither
-property — so `SCHEMA_CONDITIONAL_FIELD`, with the paths enumerated in

+
+Which way *is* charging is read off the vendored capture, and that capture

Subject: [PATCH 074/345] test(fixtures): read the adapter's published capture
instead of vendoring it
tests/fixtures/schema_one_tree.json was byte-identical to the parent/child
capture the adapter already ships as package data, and nothing checked the two
still agreed. The adapter's own README says that file exists to be read --
"never by path", and a consumer pinning a version gets the bytes that version's
parser was written against -- so the copy was one more artifact to go stale for
no benefit.
Reading the published one means the capture moves when the pinned adapter moves,
and the library's peer-conformance check against the producer covers it
transitively rather than this repository needing its own.
The two variants go with it. schema_one_tree_no_pv.json and
schema_one_tree_batteryless.json differed from the base by exactly one missing
device each, so they are now derived with schema_one_tree(without=...) and
cannot drift from it by construction.
Verified by mutation rather than by inspection: injecting a device into the
library's package data makes the integration's fixture see it.

Subject: [PATCH 075/345] docs(sensors): the shared battery convention is
discharge-positive, measured
The docstring withdrew the charge-positive claim rather than replacing it,
because nothing had settled the direction. A producer driven into
self-consumption settles it: with the grid at zero, PV 4181 W plus battery
1917 W meeting a 6099 W load, the battery is discharging and both sensors read
+1917.49.
Positive means discharging, and that is the same convention the other three
power-flow sensors follow -- pv_power positive while producing, grid_power_flow
positive while importing. Every one is "positive means power flowing toward the
house", each reached by one negation of a wire value in the opposite frame.
Prose only. No value, no id and no state class moves; the library's rename of
_charge_positive to _discharge_positive is the same kind of change.

Subject: [PATCH 076/345] fix(additions): tell sub-device entities apart in the
notification
Two commissioned chargers each gained a charge-current limit and a panel link,
and the notification listed "EVSE Charge Current Limit" twice with nothing to
distinguish them. The battery's meter read as a bare "Meter Power".
Every platform sets _attr_has_entity_name, so the registry stores only the
entity half and Home Assistant prepends the device in its own UI. A flat list
does not, so entities that differ only by which sub-device they sit on
collapsed to the same string. Two identical rows is what teaches somebody to
skip the category, which costs them the additions that matter.
Sub-device entities now carry their device's name; the panel's own do not,
because a notification that already says which panel it is about does not need
the panel name on every line. The prefix breaks collisions, and the panel is
the one device with no sibling to collide with.
Verified by mutation: reverting to the shipped behaviour fails the collision
test and nothing else.

Subject: [PATCH 077/345] refactor(notices): the firmware upgrade is a
notification, not a repair
A panel that upgraded its data model announced itself twice: a hardcoded English
persistent notification about the reload, then a translated Repair about what
the reload changed. The Repair is what the user saw first, stamped Warning and
offering to Ignore, telling them something about their panel was broken. Nothing
was. It said so in its own second sentence.
The Repair was chosen for durability, and that reason was sound: a persistent
notification lives in memory, so one raised while the owner was away died at the
next restart with nobody having read it. But durability and severity are
separate properties and only one of them was wanted.
`notices` supplies durability directly. A notice is recorded per config entry,
re-raised at every setup, and dropped only when the user dismisses it -- observed
through the registration callback rather than assumed from a restart count or an
age. That is the Repair's one real advantage with none of its meaning.
The two messages become one, and it is translated in all five shipped languages
rather than only the half that was.
Standing Repairs are cleared at setup rather than left to expire with the next
restart, because the user is looking at one now.
New-entity announcements move onto the same primitive; they had the same hole,
and worse, because their own store already recorded the entities as announced --
a restart in the wrong second meant nobody would ever be told.
The reload race is the sharp edge and is covered directly. A schema upgrade
raises a notice and schedules a reload in the same breath, so the setup that
follows can arrive before the delayed write has landed. Re-reading the store
there would drop the notice while it sat on screen; the setup keeps the live view
instead, and the test asserts on that view because the store hands a pending
write back to its own reader and would hide the bug until the next restart.
Twenty new tests, none of which existed: the schema-change handler had no
coverage at all, which is how a notification and a Repair for one event survived.
Three mutations verified -- re-reading the store on reload, dropping the entry
filter on dismissal, and dropping the REMOVED guard -- each killed by the tests
that claim them.

+"""Notifications that outlive a restart.
+
+A persistent notification lives in memory. Raise one, restart Home Assistant,
+and it is gone whether or not anybody read it. That is why the things worth
+saying exactly once have historically been filed as Repairs instead: a Repair is
+stored, so it stands until the user dismisses it.
+
+That trade is a bad one. The Repairs list means "something wants your attention
+because it went wrong" -- it is stamped with a severity, it offers to fix or
+ignore, and everything else filed there is a defect. Putting good news in it
+tells the user their panel is broken. A firmware upgrade that took nothing away
+arrived looking like a warning, which is the opposite of what it was for.
+
+This module keeps the notification and buys back the one property the Repair had
+that it lacked. A notice raised here is recorded per config entry and re-raised
+at every setup until it is dismissed, and the dismissal is *observed* rather than
+assumed: Home Assistant reports removals to a registered callback, so "the user
+has seen it" is a fact rather than a hope. A notice therefore survives a restart,
+a reload, and an owner who was on holiday when their panel upgraded.
+
+Which is durable and which is not is a real distinction, not a default. A notice
+belongs here when it reports something that happened once and cannot be
+re-derived -- a firmware upgrade, an entity that appeared. Anything re-derived

Subject: [PATCH 078/345] fix(additions,notices): adopted entities are switched
off, and a bad store file is not fatal
Two defects found by review, both in code from this release set.
**Adopted entities were announced as ready to use.** `AdoptedEntity` registers
every one of them disabled, so the notification said the opposite of the truth.
They were counted apart from the disabled ones and emitted between the two
headings, which meant a release whose only additions were adopted -- a vendor
device appearing, the case adoption exists for -- rendered no heading at all and
suppressed the how-to-enable text, the one string in the message with an action
attached. They now sit under the switched-off heading, which needs no new
translation key because it is where they always belonged.
**A malformed notice store took the integration down permanently.** The TypedDicts
are compile-time only and on-disk data violates them freely: a list where the
mapping should be, a notice with no message, a string at the top level. Each
raised straight out of setup, and out of the part above the try, so the entry
went to SETUP_ERROR with no retry and stayed dead until somebody found and
deleted the file. Home Assistant handles undecodable JSON already; the gap is
valid JSON of the wrong shape, which it hands back intact. Bookkeeping for a
notification is not worth an integration that will not load, so the load falls
back to empty, keeps whatever rows are well formed, and self-heals on the next
raise. `read_translations` gets the same guard for the same reason.
Three mutations that survived the previous round now die: recording only the
previously-announced set (which re-announced every entity on every restart,
forever -- the nothing-added path returns before that line, so the test that
looked like it covered it never reached it), dropping the `async_on_unload`
wrapper on the dismissal watch, and dropping the store shape guard.
One mutation still survives and the docstring was wrong rather than the code: the
snapshot in `_persist` is defensive, not load-bearing. A Store keeps one pending
write and every mutation site re-persists, so the difference is unobservable.
Said so plainly instead of claiming a property no test can hold.
`requirements_test.txt` pinned b4 against the manifest's b6/b5/b6. Nothing reads
it, which is how it drifted; it now matches.
Also dropped a redundant `_attr_name` assignment in `AdoptedSensor` that restated
what its base class had already set.

Subject: [PATCH 079/345] feat(sensor): the grid power sensor says whether it
is metering the grid
`sensor.*_instant_grid_power` reads the upstream lugs' meter, and that is grid
flow only where those lugs are the utility connection point. A BESS wired ahead
of the main lugs, or a panel fed by another panel, leaves it metering that
panel's own feed while `Grid Power Flow` stays site-level. Both readings are
correct and they stop being the same number, so somebody comparing them has been
unable to tell a topology from a fault. `at_service_entrance` answers that on the
sensor they are already looking at.
An attribute rather than an entity, deliberately. Topology is static -- a panel's
position in a chain does not change without an electrician -- so a binary sensor
would be a permanent row recording one unchanging boolean into the database
forever, which is the stats pollution we have refused elsewhere. It is also
additive on an entity that already exists, so it reaches an upgraded install
without touching the registry: no entity_id, no unique_id, no state_class, no
statistics. Attributes are announced by the release notes rather than by the
additions notification, which is the exception already recorded in the delta
document.
Not a Repair, because nothing is broken and there is nothing to act on. The panel
is wired the way it is wired.
Confined to the grid sensor. `SpanPanelPowerSensor` also backs feedthrough,
battery and PV, and those are what they say they are wherever the panel sits --
an attribute qualifying the grid label would be noise on them, and worse, would
read as qualifying their value.
Diagnostics carries the same fact next to both grid figures, since it is the
first thing worth knowing on a "my grid sensor reads wrong" report.
Two mutations verified dead: dropping the key check so every power sensor carries
it, and hardcoding the value True.

Subject: [PATCH 080/345] feat: hand the panel client Home Assistant's shared
HTTP client
`quality_scale.yaml` has declared `inject-websession: done` for a while, and it
was true of the config flow and of nothing that ran after it. Every runtime
schema read built a throwaway client: once at connect, and once per attempt
inside the library's retry loop, which runs while a panel finishes rebooting
after a firmware upgrade and can go five times in a row. Home Assistant already
owns a client, shares it across integrations, and closes it at shutdown.
The library gained the parameter in 3.0.0b7; this passes it. Requires that
release, so all three pin sites move together -- manifest, pyproject and
requirements_test -- since the sync script's regex stops at the first
non-numeric character and is inert on beta versions.
`get_async_client(hass)` rather than the config flow's
`verify_ssl=False` variant, and not because one is safer: the library's
bootstrap URLs are plain `http://`, so TLS never happens on this path either
way, which also means the config flow's `verify_ssl=False` is inert today. The
default client is the one every other integration already shares; asking for the
no-verify variant would stand up a second connection pool for this integration
alone and imply a TLS decision nobody is making.
The test asserts identity rather than presence, because a test that only checked
something was passed would pass equally for a fresh client built here -- which is
the thing being removed. Both mutations die: dropping the argument, and asking
for HA's other client.

Subject: [PATCH 081/345] fix(scripts): make the dependency sync actually match
a version
It has been inert for its entire life and said so to nobody. Versions were
matched with `[0-9.]+`, so `3.0.0b7` was read as `3.0.0`, which matched nothing
and rewrote nothing -- and every version this project has ever shipped is a
pre-release, so this was not an edge case, it was every case. It also only
looked for the bootstrap package, entering that branch for
`span-panel-api-schema-0` on the shared prefix and then failing its own regex on
the `-schema-0` that followed, so neither adapter was ever synced by anything.
And it had never heard of `requirements_test.txt`, which is how that file came
to pin b4 against a manifest requiring b7.
It runs on every commit through `prek.toml` with `always_run`, and again in CI
under `prek run --all-files`, reporting success each time.
The fault is the shape rather than the regex. Nothing parsed, so nothing could
report that it had not matched, and a hook that matches nothing produces no
changes -- which is indistinguishable from a tree that was already correct. This
version parses each requirement, looks the name up in the manifest, and then
reads the files back and checks them against the manifest, so a miss is an error
rather than a silent no-op.
Scoped to `[project] dependencies` rather than the whole file, and that scoping
is load-bearing: `pyproject.toml` names these same packages as editable path
overrides under `[tool.uv.sources]`, in mypy's search path, and potentially as a
uv constraint -- a specifier someone set deliberately to a different value, which
a whole-file rewrite would silently drag to the manifest's pin.
Nine tests, in `tests/` rather than beside the script in `tests/scripts/`, which
`pytest.ini` excludes with `norecursedirs`: a test that is never collected is the
same failure as a hook that never matches. Two mutations verified dead -- the old
`[0-9.]+` version pattern, and dropping the scoping.

+"""Hold every declaration of a library pin to the one in manifest.json.
+
+Home Assistant installs what `custom_components/span_panel/manifest.json`
+requires, so that file is the only one whose pins reach a user. Every other
+place the same library is named -- `pyproject.toml` for local development,
+`requirements_test.txt` for a bare pip setup -- is a copy, and a copy that drifts
+is worse than no copy: the tests pass against one version while the integration
+ships another.
+
+Run as a pre-commit hook. Rewrites the copies and exits non-zero when it changed
+something, so the commit stops and the corrected files are re-staged.
+
+**Why this was rewritten.** The previous version matched versions with `[0-9.]+`
+and so stopped at the first letter: `3.0.0b7` was seen as `3.0.0`, which matched
+nothing and silently rewrote nothing. Every version this project has ever shipped
+is a pre-release, so the hook has been inert for its whole life while reporting
+success on every commit. It also only ever looked for the bootstrap package --
+`span-panel-api-schema-0` starts with `span-panel-api`, so it entered the branch
+and then failed its own regex -- and it never knew about `requirements_test.txt`
+at all, which is how that file came to pin `b4` against a manifest requiring `b7`.
+
+The lesson is in the shape rather than the regex: nothing parsed, so nothing
+could report that it had not matched. This version parses the requirement, looks
+the name up, and verifies the result, so a miss is an error rather than a
+no-change.

Subject: [PATCH 082/345] chore: declare 2.1.0b1, so the version reads as the
beta it is
`manifest.json` and `pyproject.toml` both said `2.1.0`, a final version string,
while the thing being cut is a beta. HACS lists the release tag and Home
Assistant reports the manifest version on the device page, so shipping a beta
that calls itself `2.1.0` means a tester's diagnostics are indistinguishable
from the eventual release -- and `v2.1.0` is the tag the real release needs.
Both declarations move together, and `uv.lock` records the project's own version
so it moves with them. There is no fourth: the component has no `__version__` or
`VERSION` constant, and nothing in the suite asserts this number (the `2.1.0`
strings in the test factories are panel firmware `sw_version`, unrelated).
Unlike the library, this repository has no release workflow that checks a tag
against the committed version, so the agreement is maintained by hand.

Subject: [PATCH 083/345] chore: 2.1.0b2, because b1 was cut from the wrong
branch
`v2.1.0b1` exists on the remote and points at `94d55ae`, the head of
`feat/schema-1-adapter`. That branch is an ancestor of this one -- zero commits
this branch does not have, twenty behind it -- and its manifest pins
`span-panel-api==3.0.0b5`, `schema-0==1.0.0b4` and `schema-1==0.1.0b5`, none of
which were ever published. So HACS offered the tag, Home Assistant tried to
install three versions that do not exist, and setup never ran.
A tag that has been published to users is not worth reusing even when it points
somewhere wrong: anyone who already pulled it has that content cached under that
name. Burn the number and move on.
`2.1.0b2` sorts above `2.1.0b1` under AwesomeVersion, which is what HACS
compares, so an install sitting on the bad tag will be offered this as an
upgrade rather than having to be removed first.

Subject: [PATCH 084/345] feat(diagnostics): report the entity registry,
because the UI will not
An upgrade complaint is settled in the entity registry and none of it is
reachable from the UI. Home Assistant shows "This entity is disabled" without
saying by what, and `.storage/core.entity_registry` needs shell access that a
Home Assistant OS user does not have. Four causes look identical on screen --
the registration default applied to something the registry considers new, a user
action, a disabled config entry, a disabled device -- and they need four
different fixes.
`disabled_by` names which one it was. `unique_id` answers the question
underneath, because an entity whose id changed is a new entity however familiar
its name, and that is the difference between an upgrade defect and a surprise.
`hidden_by` and `device_id` come along for the same reason: both are registry
state an upgrade can move, and neither is legible from a screenshot.
Safe by construction rather than by redaction, which is the rule this payload is
already built to: every field is registry bookkeeping, and the serial embedded in
`unique_id` is already carried by `panel.serial_number`.
Written after spending an afternoon guessing between those four causes from
cropped screenshots and getting it wrong twice.

Subject: [PATCH 085/345] docs(changelog): one 2.1.0b2 section, and the PV area
move it was missing
`[Unreleased]` and `[2.1.0]` described the same unreleased release. 2.1.0 was
never cut, so they are merged under the version actually being published rather
than left as two lists a reader has to combine.
**The PV entry was wrong in a way worth naming.** It said the five relocated
entities keep their ids "so dashboards, automations and history follow them
across untouched. Only the card they appear on changes." The ids do survive and
that half was checked three ways. The area does not: an entity takes its area
from its device, and the new solar device starts with none, so on an upgraded
install these leave whatever area the panel is in and land in no area at all.
Area-scoped dashboards, automations and voice targeting stop matching them
silently. "Only the card changes" is exactly the sentence that would send someone
looking in the wrong place, so it now says what to do instead: assign the Solar
device an area.
Added the two things this release surfaces that had no entry: the
`at_service_entrance` attribute on Grid Power, and the entity registry in
diagnostics.

+This release raises the minimum from 2026.5.4. Home Assistant 2026.8 replaced the two device-registry calls this integration relies on — the old forms stop

+- **Grid-forming device name** as an attribute on the GFE sensor.
+- **Grid Power now says whether it is really measuring the grid**, through a new `at_service_entrance` attribute. That sensor reads your panel's upstream lugs,
+ which is grid flow only when those lugs are where the utility actually connects. Put a battery between the utility and your main lugs, or feed the panel from
+ another panel, and the same reading becomes that panel's own supply while **Grid Power Flow** stays the whole-site figure — so the two legitimately disagree,
+ and until now there was no way to tell that apart from a fault. The eBus specification was corrected on 2026-08-20 to say exactly this, after this project
+ supplied the capture that prompted it. Both readings were always correct; only the label was ever conditional.
+- **Diagnostics now include your entity registry.** Every entity this integration owns, with its unique id and — the part you cannot get anywhere else — what
+ disabled it, if anything. Home Assistant tells you an entity is disabled without telling you by what, and reading that yourself needs shell access to
+ `.storage` that a Home Assistant OS install does not give you. Four causes look identical on screen and need four different answers.

### Changed
+- **`DSM Grid State` is now more trustworthy on the new data model.** It keeps its entity id and all of its history. Previously it was _inferred_ — from the
+ battery if one was fitted, otherwise from the dominant power source and whether power was crossing the grid connection. It now reads the islanding state the
+ Microgrid Interconnect Device actually senses.
+- **`Grid Islandable` keeps working** across the upgrade. v1.0 publishes no panel-level islandable property, so the entity now reflects whether a Microgrid
+ Interconnect Device is present, which is how v1.0 says backup capability is detected.
+- **Battery model** may read differently after upgrading: the new data model separates the human-readable designation from the SKU, and this entity now shows
+ the designation. This is a library-level normalisation applied to both data models, so it happens once, at this release, rather than unpredictably during a

Subject: [PATCH 086/345] docs: warn before the firmware lands, and correct the
battery sign in both docs
**The README's headline is now the consequence, not the mechanism.** Firmware
`r202633` breaks every release up to 2.0.8, and the failure is quiet: the
integration stays connected, stays loaded, and reports every circuit as missing.
Nobody outside SPAN knows when a given panel updates and it cannot be deferred
from Home Assistant, so the only safe position is to be on 2.1.x already.
Upgrading early costs nothing -- on current firmware 2.1.x reads the panel
exactly as 2.0.8 does -- and the changeover is then seamless, with entity ids,
unique ids and statistics all surviving. What actually changes in the wire format
is still recorded, in a collapsed section, because it explains the failure rather
than motivating the action.
**The battery sign was documented backwards in both user-facing documents, and
this file had "corrected" it in the wrong direction.** Release 2.0.5 established
discharge-positive (#184); a later entry claimed the sensor had always been
charge-positive and the README was edited to match, so both told the reader to
expect the wrong sign. The code never moved: `bess_meter_power` returns
`battery.power_w` and `battery_power` negates `power_flow_battery`, and a
measured panel -- battery in self-consumption, grid at exactly zero, PV 4181 W
plus battery 1917 W meeting a 6099 W load -- reads `+1917.49` on both while
discharging. No entity changed and no reading moved; only the documentation was
ever wrong, in both directions.
**The changelog is user-facing only now.** `[Unreleased]` and `[2.1.0]` described
the same unreleased release and are one section. Nine bullets that documented how
something is built rather than what it does are gone: proxy reporting in
diagnostics, the announcement record's restart behaviour, `info`/`connection`
handling, adopted-identity freezing, notice counting, adoption diagnostics, the
write-authorisation argument, and the device-registry link form.
**README sensor documentation caught up with the code.** PV metadata moved to the
Solar sub-device and loses the panel's area, which nothing warned about; Grid
Power gained `at_service_entrance` and the reason it needs one; the five
unreliable sensors are marked off-by-default with the conformance note behind it;
adopted devices are documented for the first time.

-Support for the eBus v1.0 (parent/child) data model your panel moves to on firmware r202633 and later, and a clean transition when it does.
+### You will need this release when SPAN updates your panel
+
+SPAN firmware `r202633` replaces the way the panel publishes its data — the flat model every release up to 2.0.8 reads is retired in the same update that
+introduces the new one. There is no overlap and no setting to keep the old behaviour. **2.0.8 cannot read a panel on `r202633`**: it stays connected, reports
+every circuit as missing, and shows nothing useful.
+
+We do not control when that update reaches you, and nobody has published a schedule. Panels update on SPAN's timing, not on yours or ours. So the safe order is
+to be on this release **before** your panel changes rather than after, because afterwards you are looking at a blank integration while you work out why.
+
+**The transition itself is seamless, and that is the point of this release.** Install it and it keeps reading your panel exactly as before, on either firmware.
+When your panel does change over, the integration notices on the wire, reloads itself, and carries on — no reconfiguration, no re-pairing, no lost history. Your
+entities keep their entity ids, their unique ids and their statistics across the change. New things appear because the new firmware genuinely publishes more;

list becomes a select, and a number with its `min:max:step` becomes a number entity — all disabled and diagnostic like every other adopted entity, so a
control appears only if you go and enable it. A settable property that declares no value domain stays a reading: a select with no options and a number with no
bounds are broken controls, not safe ones.
-- **The write cannot reach a device this integration does model, by construction.** It is authorised by looking the property up in the current snapshot rather

+## ⚠️ Upgrade to 2.1.x before your panel's firmware updates, or the integration will stop working
+
+**SPAN firmware `r202633` breaks every integration release up to and including 2.0.8.** When your panel takes that update, 2.0.8 stops being able to read it.
+The integration still connects, still shows as loaded, and reports every circuit as missing — sensors go unavailable, automations stop firing, dashboards go
+blank. It does not fail loudly. It goes quiet.
+
+**Nobody outside SPAN knows when your panel will update, and you cannot defer it from Home Assistant.** Panels update on SPAN's timing. There is no schedule to
+plan around, which is why the safe move is to be on 2.1.x already rather than to wait for a signal that never comes.
+
+**Upgrading first costs you nothing.** On your current firmware, 2.1.x reads your panel exactly as 2.0.8 does — same entities, same ids, same history. It simply
+also knows how to read the new format when it arrives.
+
+**And then the changeover is seamless.** The integration detects the new format on the wire, reloads itself, and carries on:
+
+- No reconfiguration, no re-pairing, no re-authentication.
+- Entity ids, unique ids and long-term statistics all survive. Dashboards, automations and history follow.
+- New entities appear because the new firmware genuinely publishes more. Nothing you already had is removed.
+
+Upgrade afterwards instead and you reach the same place — after however long it takes you to notice, and to work out that a firmware update you were never told
+about is the reason your panel went silent.
+
+
+What actually changes in the firmware
+
+`r202633` rewrites how the panel publishes everything, rather than adding to it. The MQTT topic structure changes, and the panel stops presenting itself as a
+single flat device with a long list of properties. It presents a tree instead: the enclosure, with its lugs, circuits, battery, chargers and Microgrid
+Interconnect Device as separate devices beneath it. Every topic an integration reads moves. The old format is retired in the same update that introduces the new
+one — there is no overlap and no setting to keep the old behaviour.
+
+This has happened before, in exactly this shape. Firmware `spanos2/r202603/05` removed the v1 REST API this integration was originally built on, which is what
+the 2.0.x breaking-change notice below is about. `r202633` does the same thing to the flat MQTT format that replaced it.

+decrease or go negative, the power reading is inverted relative to every other terminal, and the downstream currents report the **upstream** service conductors
+rather than a downstream measurement. These defects predate `r202633` and are not introduced by it.

+### Adopted Devices (v1.0 data model only)
+
+The eBus schema is vendor-extensible, so your panel can publish a device type this integration has never modelled. Rather than ignoring it, the integration
+gives it a card of its own hanging off the panel, carrying whatever identity it publishes, with its readings as entities beneath it.
+
+Everything adopted arrives **disabled and diagnostic**, so nothing reaches a dashboard uninvited, and the new-entity notification names the device so you can
+find it. A property the device accepts writes to becomes a control rather than a reading — a `boolean` becomes a switch, an enumeration becomes a select, a
+number becomes a number entity — and those arrive switched off too.
+
+Two things worth knowing before you build on one:
+
+- **Nothing adopted enters long-term statistics.** No adopted entity carries a `state_class`, because the correct one is not published on the wire and guessing
+ wrong writes corrupt statistics that fixing the panel afterwards does not repair. If you want statistics from an adopted reading, wrap it in a template
+ sensor, a Riemann-sum integration or a utility meter — a deliberate choice on an entity you enabled.
+- **Devices this integration already models are never adopted.** A new property on a circuit, the battery, a charger or the panel is curated in a release
+ instead, because that is where the judgement lives about whether it should be an entity, an attribute or a line on a device card.

Subject: [PATCH 087/345] docs(readme): the entities the reference tables never
caught up with
Cross-checked every `name` in `strings.json` against the reference tables rather
than reading for plausibility. Sixty-one entity names, seven absent, five of
those label mismatches where the README says "BESS Firmware" for an entity
displayed as "Firmware Version". Two were real.
**The Microgrid Interconnect Device had no entity documentation at all** -- only a
Key Terms definition of what a MID is. Its `Grid State` sensor is the one
genuinely new reading on the v1.0 data model, since the previous firmware never
reported the state of the utility supply, and it is easy to confuse with `DSM
Grid State`, which is whether the *home* is islanded. The grid can be down while
the house runs happily off the battery. Now documented together so the
distinction is visible where someone would look for it.
**The circuit select is named "Circuit Priority"**, not "Circuit Shed Priority" as
the table said. A reader searching their entity list for the documented name
found nothing.
Also missing from the tables: EVSE Part Number entirely, and BESS Part Number.
Both are off by default, as are BESS Nameplate Capacity and PV Nameplate
Capacity, which the tables described without saying so -- the difference between
"I do not have this sensor" and "I have not switched it on".

Subject: [PATCH 088/345] chore: 2.1.0b3, on the library release that fixes the
upgrade reload
`v2.1.0.b2` was cut before the diagnostics and documentation work, so b3 carries
four commits it does not have plus the library fix that matters most.
Pins move to `span-panel-api==3.0.0b8` and `span-panel-api-schema-1==0.1.0b7`;
schema-0 is unchanged at `1.0.0b5` because nothing in it moved. b8 is the release
where a panel answering 502 during its reboot is understood as "not ready yet"
rather than as a hard failure -- the path that cost a live upgrade its automatic
reload on two Home Assistant instances, and the one thing this release exists to
promise.
The pin propagation was done by `scripts/sync-dependencies.py` rather than by
hand, which is the first real use since it was repaired. It found and rewrote
both copies and failed the commit so they would be re-staged, which is what it
was always supposed to do and never once did.

+
+### Fixed
+
+- **The integration now reloads itself after the firmware upgrade in the case that actually happens.** This is the whole promise of the release, and a live
+ upgrade found the one path where it did not hold. When a panel takes the new firmware it drops its MQTT connection, comes back a few minutes later, and
+ starts serving HTTP a little after that — and while it is still starting, it answers with `502` rather than refusing the connection, because a booting device
+ brings its network front end up before the application behind it. The integration retried a refused connection and a timeout, but treated an answered-with-502
+ as a hard failure and gave up on the first try, leaving the old reader in place. It was caught on two Home Assistant instances watching one panel through the
+ same upgrade: both went quiet and neither recovered until reloaded by hand. A `502` is now understood as **not ready yet** and waited out, for as long as a real
+ reboot takes.
+- **If following the upgrade ever fails for some other reason, you are now told what to do about it.** Previously that surfaced as a bare error in the log with
+ no indication that anything needed doing, while the integration carried on reading the panel with the wrong reader. It now says plainly that a reload is
+ needed once the panel is back up.
+
+### Added
+
+- **Diagnostics include your entity registry.** Every entity this integration owns, with its unique id and — the part you cannot get anywhere else — what
+ disabled it, if anything. Home Assistant tells you an entity is disabled without telling you by what, and reading that yourself needs shell access that a
+ Home Assistant OS install does not give you.
+
+### Changed
+
+- **The README now leads with the upgrade warning**, and documents the Microgrid Interconnect Device, adopted devices, the `at_service_entrance` attribute on
+ Grid Power, and which sensors arrive switched off.
+- **The battery power sign was documented backwards in both the README and this file, and is corrected.** Positive means **discharging**, which is what release
+ 2.0.5 established and what a measured panel confirms. No entity changed and no reading moved; only the documentation was wrong.

Subject: [PATCH 089/345] chore: pin span-panel-api 3.0.0b9
b8's 502 handling shipped without its retry window: the exception was caught and
the loop still gave up after about twenty-three seconds, against a panel that
took four minutes to come back. b9 carries the widening -- twelve attempts
backing off to thirty seconds -- and a test that pins the total against the
observed reboot.
Still 2.1.0b3; the integration itself has not changed, only what it installs.

Subject: [PATCH 090/345] chore: 2.1.0b4 on span-panel-api 3.0.0b10
b10 stops the wait for a rebooting panel from giving up. The bound was wrong
twice for the same reason -- sized against a reboot somebody had measured, and
the next reboot was not that reboot -- and exhausting it meant stranded rather
than "try again later", because nothing starts the attempt again. It also
recognises four more mid-boot answers as "still starting" rather than as failure:
a connection reset mid-request, a gateway closing without replying, and a reply
that arrives truncated.
This release also catches that condition at setup. A panel that is not ready when
Home Assistant starts now produces a retrying `ConfigEntryNotReady` instead of a
dead entry needing a human -- which matters because the two events correlate: one
power interruption takes out both the house's electrical panel and the machine
watching it, and they race each other back up.
Pins propagated by `scripts/sync-dependencies.py`, third consecutive release it
has done correctly.

+- **A panel that is still booting no longer needs a manual reload, however long it takes.** b3 taught the integration to keep waiting when a rebooting panel
+ answers with an error instead of refusing outright, but it still gave up after a few minutes — and giving up was worse than it sounds, because nothing starts
+ it again. A panel that finished booting after that point stayed unread until you reloaded by hand. It now waits for as long as your panel takes, checking
+ every thirty seconds once it settles, so a slow reboot is just a slow reboot.
+- **Your energy history is unaffected by that wait.** Energy sensors already hold their last reading through an outage for the grace period you configure
+ (fifteen minutes by default), which is what stops a gap becoming an `unknown` and a spike in your statistics. Waiting longer for the panel does not change
+ that.
+- **Several other ways a booting panel answers are now recognised as "still starting" rather than as a fault** — a connection reset mid-request, a gateway that
+ closes without replying, and a reply that arrives truncated. Each of those previously stopped the integration following the upgrade, the same way the original
+ error did.
+- **A panel that is not ready when Home Assistant starts now retries instead of failing setup.** Previously that left the integration in an error state needing
+ a human, which matters because the two events correlate: one power interruption takes out both your panel and the machine watching it, and they come back at

Subject: [PATCH 091/345] fix(binary_sensor): create Grid Islandable when the
answer is knowable
Observed on a live upgrade: the entity read `Off` on flat and went `Unavailable`
the moment the panel took r202633, on an install with no battery. Nothing about
the site changed.
This gate has now been narrowed twice for the same symptom. Gating on the flat
property alone left the entity unavailable after a v1.0 upgrade -- the panel had
not lost the capability, only the property that used to report it -- and its own
comment says so. Adding `has_mid` rescued panels that have a battery and left
every battery-less one exactly where it was, because it admitted the entity only
when the answer was going to be `True`.
For a boolean whose `False` is informative that is backwards. No MID is not
missing information, it is the information: `devices/bess.md` makes the signal
structural -- "a MID `grid` child means premises-segment backup ... neither means
no backup", and "there is no single 'islanded?' bit to reconcile" -- so a panel
without one does not island, and saying so is the answer rather than the absence
of one. `_grid_islandable` has always computed exactly that; the gate refused to
create the entity precisely when it would have said `False`.
Flat is untouched, which is the constraint that matters until the fleet moves. A
flat panel publishes the property, so the value comes from the panel as it always
has and MID presence is never consulted. A flat panel that stops publishing it
has a metadata row that fails to resolve, which is what makes the entity
unavailable and raises the Repair -- that path is deliberately left alone,
because it is the one that must not become a default presented as a reading.
Two wrong diagnoses on the way here, both discarded after reading rather than
shipped: the availability probe, which skips a field path with no metadata row at
all, and the `SCHEMA_CONDITIONAL_FIELD` labelling on three descriptions, which is
harmless for the same reason. It was the creation gate.
Marked `DUAL-SCHEMA` so the retirement is mechanical: nothing here is removed
when flat goes, since an unconditional append is already the end state -- the
branch that goes is the flat property read inside `_grid_islandable`.
Both mutations verified: withholding the v1.0 answer fails, and ignoring the flat
property fails.

Subject: [PATCH 092/345] chore: 2.1.0b5 on 3.0.0b11, and document the two
blank entities
Pins move to `span-panel-api==3.0.0b11` and `span-panel-api-schema-1==0.1.0b8`,
which carry the `dominant_power_source` fix; schema-0 stays at `1.0.0b5` because
nothing in it moved.
README gains the battery-less case in both places a reader would look: the Grid
Forming Entity deep dive now states that GFE is Grid on a panel with no battery
on both firmware generations, with the elimination that makes it so, and the MID
section says that having no MID is itself the answer for Grid Islandable rather
than a missing reading. The Grid Islandable table row no longer says "only when
reported", which was true of the gate and not of the entity.
The delta document records both, and the pattern behind them: v1.0 expresses by
*structure* what flat expressed by *property*, and code written against the
property reads the structural form as ignorance. Three instances in two days --
`grid_islandable`, `dominant_power_source`, and the PV entities' area -- so the
question to ask of every remaining `SCHEMA_CONDITIONAL_FIELD` is not "does this
field still resolve" but "is there an answer the absence itself supplies".
Both wrong diagnoses are recorded too, since the second would have quietly
changed flat's degraded behaviour had it shipped.

+### Fixed
+
+Two diagnostic entities went blank on a battery-less panel after the firmware upgrade, both because v1.0 retired the property they were reading and the
+integration treated the absence as ignorance rather than as an answer. Nothing about either site changed; the panel simply stopped publishing a value it now
+expresses another way.
+
+- **Grid Forming Entity reads `Grid` again instead of `Unknown`.** Flat published a source class outright; v1.0 names the forming **device**, and it names it on
+ the Microgrid Interconnect Device — which a panel without a battery does not have. But the answer is settled by what cannot be there: a battery needs a MID, a
+ solar inverter cannot form a grid on its own, and a panel supplying nothing is not publishing. What remains is a generator, and SPAN with no generator
+ interface treats one as the grid. So on a panel with no MID the grid is what is forming, which is exactly what flat had been reporting all along.
+- **Grid Islandable reads `Off` again instead of going unavailable.** v1.0 publishes no islandable property at all — the specification makes it structural
+ instead, where the presence of a MID is what says a panel can island. Having no MID is therefore the answer rather than the absence of one, and the entity was
+ being withheld precisely when it would have said "no".
+- **Neither changes anything on a panel still running the older firmware.** Both keep reading the published property exactly as before, and both still go
+ unavailable if a panel that should publish one stops — which is a real fault worth surfacing, as distinct from a property the newer firmware never had.

+brings a MID), PV cannot form a grid on its own (anything that can is a grid-forming inverter, which is a MID), and None describes a panel supplying nothing,
+which is a panel that is not reporting at all. What remains is a generator, and SPAN with no generator interface treats one as the grid. So Grid is what a
+battery-less panel reports, which is what the older firmware reported too.
+
#### What the Panel Can Detect
**Grid loss** — The panel independently detects grid loss via its own voltage monitoring, even if BESS communication is already lost. The MID is still closed at

Subject: [PATCH 093/345] refactor(sensor): file Import Limit as a diagnostic,
with its siblings
It was the only panel-level ampere value on the primary card, and the only
member of its own PCS group outside the Diagnostic section -- both of its
siblings were already there.
This reverses a deliberate decision, which had a test and a rationale: "a PCS
throttling import is a fact about the user's electricity supply, not about the
integration's health, so it is not filed as a diagnostic". That reads
`DIAGNOSTIC` as being about the integration. Home Assistant's category is about
the *device* -- "a configuration parameter or diagnostics of a device" -- and by
the earlier standard `l1_voltage` and `main_breaker_rating` are facts about the
user's supply too, and both are diagnostic.
The line this codebase actually draws is not "amps are diagnostic", which would
misfile two entities that are correctly primary: `circuit_current` and
`evse_advertised_current` are amps and are what a circuit or a charger is doing
right now. It is that the panel's own voltages, lug currents, breaker ratings and
limits describe the installation rather than its activity. Import Limit is one of
those -- a ceiling the panel arbitrated, carrying the four limits it was
arbitrated from as attributes.
Presentational only. The entity id, its history and its long-term statistics are
untouched, `state_class` stays, and automations and templates are unaffected;
the category groups it on the device page and keeps it out of auto-generated
dashboards.
Done now because the entity is days old and has appeared in exactly one release's
addition notice, so no installation has a dashboard or history depending on where
it sits. Later would cost something; today costs nothing.

Subject: [PATCH 094/345] chore: 2.1.0b6, so the Import Limit move ships
`v2.1.0b5` was tagged at `0442c04`, one commit before the category change, so it
went out without it. The changelog credited the move to b5, which was wrong the
moment that tag was cut -- an entry describing something a release does not
contain is worse than no entry, because it is the release notes that a user
checks when the thing they read about is not there.
Moved to its own `[2.1.0b6]` section. Library pins are unchanged at
`3.0.0b11` / `1.0.0b5` / `0.1.0b8`; nothing in them moved.
Also dropped "has appeared in one release" from the rationale, which stopped
being true when b5 shipped. The argument does not depend on it: the entity is
days old either way, and the same change after general firmware rollout would
cost something.

Subject: [PATCH 095/345] fix(circuits): report the voltage we can justify, not
a default
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
`construct_voltage_attribute` returned None for a breaker occupying more than
two positions, and every caller turned that into 240 with `or 240` — so the one
case we cannot infer became the one case we asserted most confidently. The
topology service had its own copy of the inference and answered 120 for
everything that was not exactly two-pole.
Callers now omit the attribute when the pole count does not determine the
voltage, and the topology service reads the same helper as the entities.
`construct_tabs_attribute` and the circuit-number entity id builder no longer
branch on one-or-two positions either: they name every position the breaker
occupies. Three positions used to drop the attribute and log that the hardware
was "not valid for US electrical system", which is a poor way to meet input we
have merely not seen. SPAN publishes only 1- and 2-pole breakers, so the wider
form is unreachable on SPAN hardware and exists so unexpected input degrades
into something readable.

Subject: [PATCH 096/345] docs: one 2.1.0 entry, written for the people
upgrading
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The changelog carried five separate beta sections whose combined story was
mostly internal: a retry that was fixed three times, documentation corrected in
both directions, entities promised in b2 and repaired in b5. A reader upgrading
from 2.0.8 sees none of that history — they see one release. So the betas are
collapsed into a single 2.1.0 entry stating final behaviour, keeping the SPAN
firmware transition and the self-reloading upgrade path, which are the reasons
the release exists. Added is one sentence per item rather than a paragraph.
Both documents also framed the schema generation as something a reader chooses
between. The v2 eBus prerequisites were repeated at the top of 2.0.2 through
2.0.6 as live cautions and are now stated once, in past tense, on the 2.0.1
entry that introduced them. Every `v1.0 data model only` and `v2 only` marker is
gone from the README's headings, tables and prose: it is just the firmware the
panel will be running, and the conditions that genuinely vary per install —
"only when BESS commissioned", "only when the feeding circuit reports it" —
were already stated where they matter.

All notable changes to this project will be documented in this file.
-## [2.1.0b6] - 8/2026
+## [2.1.0] - 8/2026
-### Changed
-
-- **Import Limit moves to the Diagnostic section of the device page.** It sits with the panel's other electrical characteristics — voltages, lug currents,
- breaker ratings — rather than beside the power readings, which is where the rest of the integration files a limit the panel arbitrated as opposed to a
- measurement of what is flowing. Both of its Power Control System siblings were already there. Nothing else changes: the entity id, its history and its
- long-term statistics are untouched, and automations and templates referring to it are unaffected. Moved now because the entity is days old, so no dashboard
- depends on where it sits; the same change after general firmware rollout would cost something.
-
-## [2.1.0b5] - 8/2026
-
-### Fixed
-
-Two diagnostic entities went blank on a battery-less panel after the firmware upgrade, both because v1.0 retired the property they were reading and the
-integration treated the absence as ignorance rather than as an answer. Nothing about either site changed; the panel simply stopped publishing a value it now
-expresses another way.
-
-- **Grid Forming Entity reads `Grid` again instead of `Unknown`.** Flat published a source class outright; v1.0 names the forming **device**, and it names it on
- the Microgrid Interconnect Device — which a panel without a battery does not have. But the answer is settled by what cannot be there: a battery needs a MID, a
- solar inverter cannot form a grid on its own, and a panel supplying nothing is not publishing. What remains is a generator, and SPAN with no generator
- interface treats one as the grid. So on a panel with no MID the grid is what is forming, which is exactly what flat had been reporting all along.
-- **Grid Islandable reads `Off` again instead of going unavailable.** v1.0 publishes no islandable property at all — the specification makes it structural
- instead, where the presence of a MID is what says a panel can island. Having no MID is therefore the answer rather than the absence of one, and the entity was
- being withheld precisely when it would have said "no".
-- **Neither changes anything on a panel still running the older firmware.** Both keep reading the published property exactly as before, and both still go
- unavailable if a panel that should publish one stops — which is a real fault worth surfacing, as distinct from a property the newer firmware never had.
-
-## [2.1.0b4] - 8/2026
-
-### Fixed
-
-- **A panel that is still booting no longer needs a manual reload, however long it takes.** b3 taught the integration to keep waiting when a rebooting panel
- answers with an error instead of refusing outright, but it still gave up after a few minutes — and giving up was worse than it sounds, because nothing starts
- it again. A panel that finished booting after that point stayed unread until you reloaded by hand. It now waits for as long as your panel takes, checking
- every thirty seconds once it settles, so a slow reboot is just a slow reboot.
-- **Your energy history is unaffected by that wait.** Energy sensors already hold their last reading through an outage for the grace period you configure
- (fifteen minutes by default), which is what stops a gap becoming an `unknown` and a spike in your statistics. Waiting longer for the panel does not change
- that.
-- **Several other ways a booting panel answers are now recognised as "still starting" rather than as a fault** — a connection reset mid-request, a gateway that
- closes without replying, and a reply that arrives truncated. Each of those previously stopped the integration following the upgrade, the same way the original
- error did.
-- **A panel that is not ready when Home Assistant starts now retries instead of failing setup.** Previously that left the integration in an error state needing
- a human, which matters because the two events correlate: one power interruption takes out both your panel and the machine watching it, and they come back at
- their own pace.
-
-## [2.1.0b3] - 8/2026
-
-### Fixed
-
-- **The integration now reloads itself after the firmware upgrade in the case that actually happens.** This is the whole promise of the release, and a live
- upgrade found the one path where it did not hold. When a panel takes the new firmware it drops its MQTT connection, comes back a few minutes later, and
- starts serving HTTP a little after that — and while it is still starting, it answers with `502` rather than refusing the connection, because a booting device
- brings its network front end up before the application behind it. The integration retried a refused connection and a timeout, but treated an answered-with-502
- as a hard failure and gave up on the first try, leaving the old reader in place. It was caught on two Home Assistant instances watching one panel through the
- same upgrade: both went quiet and neither recovered until reloaded by hand. A `502` is now understood as **not ready yet** and waited out, for as long as a real
- reboot takes.
-- **If following the upgrade ever fails for some other reason, you are now told what to do about it.** Previously that surfaced as a bare error in the log with
- no indication that anything needed doing, while the integration carried on reading the panel with the wrong reader. It now says plainly that a reload is
- needed once the panel is back up.
-
-### Added
-
-- **Diagnostics include your entity registry.** Every entity this integration owns, with its unique id and — the part you cannot get anywhere else — what
- disabled it, if anything. Home Assistant tells you an entity is disabled without telling you by what, and reading that yourself needs shell access that a
- Home Assistant OS install does not give you.
+### You will need this release when SPAN updates your panel
-### Changed
+SPAN firmware `r202633` replaces the way the panel publishes its data — the wire model every release up to 2.0.8 is retired in the same update that introduces
+the new one. There is no wire overlap and no setting to keep the old behaviour. **2.0.8 cannot read a panel on `r202633`**: it stays connected, reports every
+circuit as missing, and shows nothing useful.
-- **The README now leads with the upgrade warning**, and documents the Microgrid Interconnect Device, adopted devices, the `at_service_entrance` attribute on
- Grid Power, and which sensors arrive switched off.
-- **The battery power sign was documented backwards in both the README and this file, and is corrected.** Positive means **discharging**, which is what release
- 2.0.5 established and what a measured panel confirms. No entity changed and no reading moved; only the documentation was wrong.
+We do not control when that update reaches you, and the schedule belongs exclusively to SPAN. Panels update on SPAN's timing, not on yours or ours. A mandatory
+upgrade that keeps working therefore demands a release that can adapt on connection, and adapt again as necessary. If uninterrupted integration matters to you,
+be on this release **before** your panel changes — afterwards you are looking at a blank integration while you work out why.
-## [2.1.0b2] - 8/2026
+**The transition itself is seamless.** Install 2.1.0 early and your only outage is the firmware update itself. When your panel changes over, the integration
+notices on the wire, reloads itself, notifies you, and carries on — no reconfiguration, no re-pairing, no lost history. Your entities keep their entity ids,
+their unique ids and their statistics across the change. New things appear because the new firmware publishes a bit more and because devices appropriate to your
+install are added; nothing you already had goes away. A log line and a one-time notification tell you exactly what happened, so take a screenshot. If you
+experience an extended delay, reload the integration.
-### You will need this release when SPAN updates your panel
+**A panel that is still rebooting is waited out, for as long as your panel takes.** Taking the firmware upgrade drops the panel's connection for several minutes
+— four or more is not uncommon once the panel receives its upgrade file. The integration keeps checking until the panel answers properly.

-to be on this release **before** your panel changes rather than after, because afterwards you are looking at a blank integration while you work out why.
+**A firmware upgrade that adds a capability reloads as well**, so hardware your panel starts reporting — the Microgrid Interconnect Device, the shed forecast,
+the power control system, battery telemetry, DER link health — turns into entities when it appears rather than at your next restart.
-**The transition itself is seamless, and that is the point of this release.** Install it and it keeps reading your panel exactly as before, on either firmware.

### Added
-- **Your panel's Microgrid Interconnect Device appears as its own device** on the new data model, carrying **Grid State** — the health of the utility supply
- itself, which the previous firmware never reported. Everything about it is additive; no existing entity moves or changes id.
-- **The integration notices a firmware upgrade and reloads itself.** A panel that becomes v1.0 while Home Assistant is running used to keep reading the tree
- with the old parser, reporting every circuit as missing until you reloaded by hand. It now detects the change, reloads, writes a log line, and raises a
- one-time notice explaining what changed.
-- **Grid-forming device name** as an attribute on the GFE sensor.
-- **Grid Power now says whether it is really measuring the grid**, through a new `at_service_entrance` attribute. That sensor reads your panel's upstream lugs,
- which is grid flow only when those lugs are where the utility actually connects. Put a battery between the utility and your main lugs, or feed the panel from
- another panel, and the same reading becomes that panel's own supply while **Grid Power Flow** stays the whole-site figure — so the two legitimately disagree,
- and until now there was no way to tell that apart from a fault. The eBus specification was corrected on 2026-08-20 to say exactly this, after this project
- supplied the capture that prompted it. Both readings were always correct; only the label was ever conditional.
-- **Diagnostics now include your entity registry.** Every entity this integration owns, with its unique id and — the part you cannot get anywhere else — what
- disabled it, if anything. Home Assistant tells you an entity is disabled without telling you by what, and reading that yourself needs shell access to
- `.storage` that a Home Assistant OS install does not give you. Four causes look identical on screen and need four different answers.
+- **Your panel's Microgrid Interconnect Device appears as its own device**, carrying **Grid State** — the health of the utility supply itself, which your panel
+ never reported before.
+- **Grid Power now says whether it is really measuring the grid**, through a new `at_service_entrance` attribute: false where a battery or another panel sits
+ between the utility and your main lugs, which is when it and **Grid Power Flow** legitimately disagree.
+
+- **Your solar inverter gets a device of its own** rather than rendering as diagnostic sensors on the panel's card; the five PV entities keep the entity ids,
+ unique ids and history they have today.
+- **Assign the new Solar device to an area** — those five no longer inherit the panel's area, which quietly drops them from area-scoped dashboards, automations
+ and voice commands until you do.
+- New installations get `sensor.span_panel_solar_pv_vendor` and friends where existing ones keep `sensor.span_panel_pv_vendor`; both are correct and neither
+ will change again.
+
+- **EVSE Charge Current Limit** — a settable ceiling on each commissioned SPAN Drive, the first control this integration has that changes something on a charger
+ rather than on the panel.
+- The maximum is the one your installer commissioned, read from the panel: a higher value is refused rather than quietly rounded down, and the control is
+ unavailable rather than invented where the rating is not published.
+- The control appears only where the panel says the limit can be changed, and reports a change still in flight as a `charge_current_limit_target` attribute.
+
+- **PV Panel Link and EVSE Panel Link** — the panel's own report of the link to your inverter and to each charger, which is the fact **BESS Connected** has
+ always shown for the battery.
+- **EVSE Panel Link is not EV Connected**: one is the panel reaching the charger at all, the other is the charger reporting a plugged-in vehicle, and they can
+ disagree mid-session.
+
+- **BESS Meter Power** — what the battery itself reports it is charging or discharging at, beside the panel's arbitrated **Battery Power**. Enabled by default.
+- **BESS Communication State** — the battery's own `OK` / `DEGRADED` / `LOST` / `UNKNOWN` view of its link, which can differ from the panel's. Diagnostic, off
+ by default.
+- **Both battery power sensors read positive when discharging**, settled by measurement on a live panel — the same convention as PV Power producing and Grid
+ Power Flow importing.
+
+- **Time to Priority Shed and Backup Time Remaining** — how long before the panel starts shedding circuits and how long before the battery is spent. Enabled by
+ default.
+- Each forecast carries its full-charge equivalent and the panel's own `forecast_confidence` as attributes, rather than as two more near-constant entities.
+
+- **Import Limit, Binding Constraint and PCS Active** — the current limit your panel enforces, which rule set it, and whether anything is being throttled right
+ now. Filed under Diagnostics with the panel's other electrical characteristics.
+- **Import Limit carries the whole arbitration as attributes**: the four constraint limits the panel reconciled, each one's `_enablement` and `_active` flag,
+ and `pcs_enabled`.
+- **Every circuit's power sensor gains `pcs_managed` and `pcs_priority`** where the circuit reports them — the shed order when an import limit binds, which is
+ not the backup tier the existing `shed_priority` names.
+- All three entities appear even when the PCS is switched off, because that is a state, and the state most panels are in.
+
+- **New kinds of device your panel gains no longer wait for a release.** SPAN's data model is vendor-extensible, so a device type nobody has modelled can turn
+ up at any time; one now gets a card of its own hanging off the panel, with whatever it publishes as entities beneath it, all disabled and diagnostic.
+- **A property such a device accepts writes to becomes a control**: a boolean becomes a switch, an enum a select, a bounded number a number entity, constrained
+ to what the device declared and nothing invented.
+- **Nothing adopted enters long-term statistics** — `state_class` is not declared on the wire and a wrong guess writes corrupt statistics; wrap an adopted
+ reading in a template sensor or utility meter if you want them.
+- Devices this integration does model are deliberately not adopted: a new property on a circuit, the battery, a charger or the panel stays curated in a release,
+ where the judgement about it lives.
+
+- **Your panel's own card shows what the panel says it is** — manufacturer, model and hardware revision read from the enclosure rather than assumed, once your
+ panel publishes them.
+- **Part Number** diagnostic sensor on every SPAN Drive, matching the one the battery already has. Off by default.
+- **Circuit Priority's shed policy is readable**: `dsm_state` gains `shed_algorithm` and the two state-of-charge thresholds that decide when circuits shed and
+ when they come back.
+- **Grid-forming device name** as an attribute on the Grid Forming Entity sensor.
+- **Diagnostics include your entity registry** — every entity this integration owns, its unique id, and what disabled it, which Home Assistant will not
+ otherwise tell you.
### Changed
-- **`DSM Grid State` is now more trustworthy on the new data model.** It keeps its entity id and all of its history. Previously it was _inferred_ — from the
- battery if one was fitted, otherwise from the dominant power source and whether power was crossing the grid connection. It now reads the islanding state the
- Microgrid Interconnect Device actually senses.
-- **`Grid Islandable` keeps working** across the upgrade. v1.0 publishes no panel-level islandable property, so the entity now reflects whether a Microgrid
- Interconnect Device is present, which is how v1.0 says backup capability is detected.
-- **Battery model** may read differently after upgrading: the new data model separates the human-readable designation from the SKU, and this entity now shows
- the designation. This is a library-level normalisation applied to both data models, so it happens once, at this release, rather than unpredictably during a
- firmware update.

-- **A device the panel publishes that this integration has never modelled now appears, instead of appearing nowhere.** SPAN positions the panel as the hub for
- whatever plugs into it and the eBus schema is explicitly vendor-extensible, so a device type nobody modelled is an expected arrival — and until now it
- produced no device, no entity and no sign it was there. Such a device now gets a card of its own hanging off the panel, carrying whatever `info` it publishes,
- with its readings as entities beneath it. Everything adopted arrives **disabled and diagnostic**: nothing reaches a dashboard uninvited, and the new-entity
- notice names the device so you can find it.
-- **Devices this integration does model are left alone, deliberately.** A new property on a circuit, the battery, a charger or the panel is not adopted — it is
- curated in a release, because that is where the judgement lives about whether it should be an entity, an attribute, or a line on a device card. Automatic
- adoption would spend an `entity_id` permanently on a machine-derived shape before anyone made that call. The sixteen Power Control System properties that
- curation collapsed into one entity and thirteen attributes are the worked example of what a rule cannot produce.
-- **Nothing adopted enters long-term statistics, and that is a decision rather than an omission.** No adopted entity carries a `state_class`. It is not declared
- on the wire and cannot be derived from one — this integration ships `feedthroughEnergyProducedWh` as `TOTAL` beside `mainMeterEnergyProducedWh` as
- `TOTAL_INCREASING`, same unit and same device class — and a wrong one writes corrupt statistics that fixing the panel afterwards does not repair. Enrolling a
- property nobody asked for into long-term statistics is also a permanent write to your recorder database. If you want statistics from an adopted reading, wrap
- it in a template sensor, a Riemann-sum integration or a utility meter: that is your call, made on an entity you chose to enable.
-- **A property an adopted device accepts writes to becomes a control, not just a reading.** A declared `boolean` becomes a switch, an `enum` with its option
- list becomes a select, and a number with its `min:max:step` becomes a number entity — all disabled and diagnostic like every other adopted entity, so a
- control appears only if you go and enable it. A settable property that declares no value domain stays a reading: a select with no options and a number with no
- bounds are broken controls, not safe ones.
-- **Your panel stays the authority on the value.** Nothing is translated or clamped on the way out: this integration knows an adopted property's declaration and
- nothing else, so inventing a bound would be inventing a fact about your hardware. The control constrains you to what the device declared, and the panel
- accepts or refuses.
-
-- **Your solar inverter gets a device of its own, on panels running the v1.0 data model.** Its vendor, model and nameplate capacity used to render as diagnostic
- sensors on the _panel's_ card, beside the panel's own manufacturer and model — so the card whose job is telling you which enclosure this is read as though the
- enclosure were an Enphase inverter. It now has a card like the battery and the chargers already do, carrying the firmware version the panel has been
- publishing all along.
-- **If you already have these sensors, nothing about them changes.** The five entities that move to the new card — PV Power, PV Vendor, PV Product, PV Nameplate
- Capacity and PV Panel Link — keep the entity ids and unique ids they have today, so dashboards, automations and history follow them across untouched.
-- **They do lose the panel's area, though, and nothing warns you.** An entity takes its area from the device it sits on unless you set one, and the new solar
- device starts with no area. So if your panel is assigned to an area, these entities were in it yesterday and are in no area today — which quietly stops them
- matching area-scoped dashboards, area-scoped automations and scripts, and voice commands that target a room. Assign the new **Solar** device to an area and
- they behave as before. Worth doing before you go looking for what broke.
-- **New installations get different entity ids for these five, and that is intended.** Home Assistant derives a new entity's id from the name of the device it
- sits on, so a system installed from now on gets `sensor.span_panel_solar_pv_vendor` where a system installed before this release keeps
- `sensor.span_panel_pv_vendor`. Both are correct and neither will change again: an existing system must never have an id renamed under it, and a new one gets
- the id Home Assistant would give it. If you are comparing two SPAN systems and their PV entity ids differ, install date is why. The unique ids are the same on
- both, and both sets of entities sit on the same new card.
-
-- **Your panel's own card now shows what the panel says it is** — manufacturer, model and hardware revision, read from the enclosure rather than assumed. A
- panel on the older data model publishes none of the three and keeps exactly the card it has today; the hardware revision row is left off rather than shown
- blank where no revision is published.
-- **Every SPAN Drive gets a Part Number** diagnostic sensor, matching the one the battery already has. Off by default.
-- **Circuit Priority's shed policy is readable.** The `dsm_state` sensor gains `shed_algorithm` and the two state-of-charge thresholds that decide when circuits
- shed and when they come back — the numbers that make the panel's shed behaviour predictable rather than surprising. A policy this integration does not
- recognise keeps its name and carries the panel's raw document beside it, so you can read what a parser could not.
-
-- **A charge-current limit you can set, on panels running the v1.0 data model.** Each commissioned SPAN Drive gets an **EVSE Charge Current Limit** number on
- its own device — the ceiling the charger offers your vehicle, which you can lower to charge more slowly and raise back. It is the first control this
- integration has that changes something on a charger rather than on the panel.
-- The maximum you can ask for is the one your installer commissioned, read from the panel rather than assumed: the box will not accept a value above the
- charger's rated current, and neither will anything else — a value beyond it is refused before it is sent, not quietly rounded down to something you did not
- ask for. If the panel has not yet published what the charger is rated for, the control reports unavailable instead of offering an invented range.
-- The control appears only where the panel says the limit can be changed. A charger that publishes its limit as read-only gets no control, which is the same
- distinction **Circuit Priority** already makes for a circuit commissioned never-backup.
-- While the panel is acknowledging a change it has not yet applied, the requested value shows as a `charge_current_limit_target` attribute and the state stays
- the limit the charger is still enforcing — the same way Circuit Priority reports a priority change in flight.
-
-- **Whether your panel can reach your solar inverter and each of your chargers, on panels running the v1.0 data model.** **PV Panel Link** and **EVSE Panel
- Link** are the same fact **BESS Connected** has always shown for the battery: the panel's own report of the link to a device it feeds. The battery's version
- worked because the panel publishes it on the main lugs; the inverter's and each charger's are published by the circuit that feeds them, and nothing read that
- half — so one of your three device classes had a link sensor and the others did not.
-- **EVSE Panel Link is not EV Connected.** EV Connected is the charger reporting that a vehicle is plugged in. EVSE Panel Link is the panel reporting that it
- can reach the charger at all. A charger part-way through a session behind a link the panel has lost shows a plugged-in vehicle and a dead link at the same
- time, which is exactly the case where you want to know which of the two you are looking at. The new sensors are diagnostics; EV Connected is unchanged.
-- Each sensor is created only where a circuit publishes the link record for that device, and per charger rather than per panel — two chargers whose circuits
- report differently get two sensors that say different things. A circuit that feeds ordinary loads publishes no such record, which is normal and is not
- reported as a fault, and a panel that starts publishing one picks the sensors up on the reload the integration already performs.
-
-- **Your battery's own meter and its own link health, on panels running the v1.0 data model.** **Meter Power** is what the BESS itself reports it is charging or
- discharging at, as distinct from the panel's **Battery Power**, which is the enclosure's arbitrated figure. Both have been on the wire since firmware r202633
- and nothing read either. Meter Power is enabled by default; **Communication State** — the BESS's own `OK` / `DEGRADED` / `LOST` / `UNKNOWN` report on its link
- — is a diagnostic and is off by default, since it is only interesting when something is wrong.
-- **Both battery power sensors read positive when the battery is _discharging_**, and that direction was settled by measurement rather than by reading. With the
- battery driven into self-consumption and the grid at exactly zero — PV 4181 W plus battery 1917 W meeting a 6099 W load, so the battery can only be supplying
- — both sensors read `+1917.49`. The two values arrive from the panel in opposite sign conventions and are normalised to this one, so they agree with each
- other and with the sensors beside them: PV Power is positive while producing, Grid Power Flow positive while importing, Battery Power positive while
- discharging. Every one is "positive means power flowing toward the house".
-- **Communication State is not the same thing as BESS Connected.** The binary sensor is the _panel's_ view of the link, from the enclosure's connection record;
- the new sensor is the _battery's_ view of it. A BESS can report its own link lost while the panel still claims it, and now you can see that.
-- Both sensors are created only where the BESS publishes the reading behind them — a battery on the older data model, or one whose firmware publishes only one
- of the two, gets no entity for what it cannot report rather than one permanently unknown, and a BESS that gains the capability on a firmware upgrade picks the
- sensors up on the reload the integration already performs.
-- **Backup planning, in minutes: two new sensors on panels running the v1.0 data model.** **Time to Priority Shed** is how long before the panel starts shedding
- circuits, and **Backup Time Remaining** is how long before the battery is spent. Your panel has been publishing both since firmware r202633 and nothing read
- them; they are the numbers you would actually set an alarm on, so they are enabled by default and sit beside the power and energy sensors rather than under
- diagnostics.
-- **Each forecast sensor carries the refinements that qualify it** as attributes: `full_charge_time_to_priority_shed` / `full_charge_total_time_remaining` —
- what the same estimate would be from a full battery — and `forecast_confidence`, the panel's own `LOW` / `MEDIUM` / `HIGH` assessment of the estimate. They
- refine a number already on screen rather than adding two near-constant entities to your entity list.
-- Both sensors are created only where the panel publishes the estimate behind them. A panel on the older data model, or one whose firmware publishes only part
- of the forecast, gets no entity for what it cannot report rather than one permanently unknown — and a panel that gains the capability on a firmware upgrade
- picks the sensors up on the reload the integration already performs.
-- **What is limiting your import, in amps: three new entities on panels running the v1.0 data model.** **Import Limit** is the current limit your panel is
- actually enforcing, **Binding Constraint** names which rule set it — your service rating, a utility envelope, an operator cap, a limit you asked for — and
- **PCS Active** says whether anything is being throttled right now. Your panel has published all of this since firmware r202633 and nothing read it.
-- **Import Limit carries the whole arbitration as attributes**: the four constraint limits the panel reconciled (`feed_import_limit`, `operator_import_limit`,
- `off_grid_import_limit`, `requested_import_limit`), each one's `_enablement` and `_active` flag, and `pcs_enabled`. They explain the enforced number rather
- than being numbers to watch, and most of them change only when somebody reconfigures the panel — so they refine an entity you already have instead of adding
- twelve to your entity list.
-- **Every circuit's power sensor gains `pcs_managed` and `pcs_priority`** where the circuit reports them: whether the Power Control System manages that circuit,
- and where it sits in the shed order when an import limit binds. `pcs_priority` is a different thing from the existing `shed_priority`, which is the backup
- tier — a circuit may take part in one policy, both, or neither.
-- All three entities are created wherever the panel publishes the capability, **including when the PCS is switched off**. A panel reporting a 0 A limit with

- entities nobody could build a dashboard on.

Subject: [PATCH 097/345] feat(extension): surface vendor properties on devices
we already model
A publisher adding a property to the BESS, a charger, a circuit or the panel
reached the user nowhere: it became a declaration-only discovery row, visible
in a diagnostics attachment and nowhere else. This integration should not be
the gatekeeper on what a publisher can reach a user with, so those properties
now become entities on the device card they belong to -- disabled, diagnostic,
and named in plain wire vocabulary so they read as uncurated, which they are.
**An adopted extension is a terminal identity.** Nothing promotes, re-homes or
migrates one. It changes only on an external trigger: the publisher stops
publishing it, or better metadata arrives. Curation is never blocked by one
existing -- ids are permanent, identity is not.
**Nothing is ever removed.** A row the user deletes returns, disabled, while
the property is still published, so deletion is not suppression and none is
built. Deletion sticks exactly when publishing has stopped, because then
nothing exists to recreate it from.
The unique_id is the one irreversible commitment, so it ships with its tests:
span_{serial}_adopted_{scope}/{node}/{property}
anchored on the serial and the curated scope, addressed by the wire path
verbatim -- upstream's own capability-catalog spelling. Verbatim is what makes
it injective: `battery-2` + `cell-temperature` and `battery` + `2-cell-
temperature` collapse under any normalising scheme and stay distinct here. Not
the eBus proxy composition, whose ids upstream states are local handles rather
than identities and are unstable across the proxy-to-native transition.
Read-only, no controls: these sit beside curated controls that do real work --
the EVSE limit refuses a value above the commissioned ceiling, the islanding
assertion translates GRID into ON_GRID -- and a generic write path would have
neither. The platform is a one-way door enforced in `resolve_platform`: an
entity domain is part of entity_id and the registry refuses a cross-domain
rename, so whatever domain a row is registered under wins however the
declaration later changes. Metadata may reshape everything else freely, which
is safe precisely because no extension entity carries a `state_class` and so
has no statistics for a unit change to corrupt.
A per-device cap bounds a misbehaving publisher, since rows are permanent and
nothing removes them, and the additions notice collapses them one line per
device -- fifteen new vendor readings must not cost the user the curated
additions in the same message.
Requires span-panel-api 3.0.0b12 and span-panel-api-schema-1 0.1.0b9, which
carry `extension_properties`.

Subject: [PATCH 098/345] chore: 2.1.0b7, and the changelog stops saying the
opposite
The version bump the extension work needed: b6 ships neither the new entities
nor the library pins they require, so HACS would offer nobody the change.
The changelog entry replaces a bullet rather than adding one. It said a new
property on a device this integration models "stays curated in a release" --
true when it was written, and the precise thing this release changes.

Subject: [PATCH 099/345] docs(readme): adopted vendor readings, and what the
delete button does
The Adopted Devices section still said devices this integration models are
never adopted, which this release reverses, so that bullet is replaced rather
than joined by a contradicting one.
The new section covers what a vendor reading is, why it arrives switched off
and read-only, why it keeps the panel's plain wording, and the delete
behaviour, which is the part nobody would guess: deleting one hides it until
the next reload while the property is still published and removes it for good
once publishing stops. It also states plainly that these are permanent in id
but not in identity -- a later curated entity is a new entity, which is the
trade for surfacing a reading the moment it appears.

+
+### Adopted Vendor Readings
+
+The other half of vendor extensibility. A publisher can add a property to a device this integration already models — the battery, a charger, the solar inverter,
+a circuit or the panel itself — and until 2.1.x that reading went nowhere: it appeared in the diagnostics download and in no entity list. It now becomes an
+entity on that device's own card. The wire already says which device and node it belongs to, so it has a home; what it does not say is how important it is.
+
+They behave like adopted devices in the ways that matter, and differ in two:
+
+- **They arrive switched off and filed as diagnostics**, so nothing lands on a dashboard uninvited, and the new-entity notification names the device with a
+ count rather than listing each one — fifteen new vendor readings would otherwise cost you the curated additions in the same message.
+- **They are readings only — never switches, selects or number boxes**, even where the panel says the property accepts writes. These sit beside curated controls
+ that do real work, such as the charge limit that refuses a value above what your charger was commissioned for, and a generic control would sit there with none
+ of that. If a control is worth having, it arrives curated in a release.
+- **They keep the panel's own wording**, so a vendor property on the battery reads `Battery 2 Cell Temperature` rather than something tidied up. Deliberately
+ plainer than a curated entity's name: it is how you tell at a glance which entities this integration designed and which it is passing through.
+- **Nothing adopted enters long-term statistics**, exactly as for adopted devices, and here it buys something extra: with no statistics behind them, a later
+ release can correct one of these entities' units, device class or category with nothing to repair.
+
+**What the delete button does**, since it is not quite what you would expect:
+
+- Delete one while your panel is still publishing that property and it comes back — switched off — at the next reload. There is no setting to suppress it,
+ because leaving it switched off is already that.
+- Delete one after your panel has stopped publishing it and it stays gone, because nothing exists to recreate it from.
+
+So deletion means "hide it until next time" for a live reading and "clear it out" for a dead one, and your panel decides which. A property your panel stops
+publishing is left in place reading unknown rather than removed: silence on the wire does not distinguish a property that is gone from one that has not arrived
+yet, and deleting your entity on a guess is not something an upgrade should do.
+
+**These entities are permanent in id, not in identity.** If one of these readings is later curated properly, the curated entity is a new entity with its own id
+and its own history — the adopted one is not renamed into it. That is the trade for surfacing a reading the moment it appears rather than waiting for a release
+to model it, and it is why a vendor reading you have come to depend on is worth mentioning in an issue: curation is what turns it into something with a real
+name, a proper category and statistics.

Subject: [PATCH 100/345] fix(additions): name a handful of vendor readings
instead of counting them
A live b7 install added two vendor readings to the panel -- a postal code and a
time zone, the only two properties that panel declares and this integration
maps nowhere -- and the notification said "Span Panel (2 entities)". That is
strictly less than naming them: the collapse was written for a firmware update
adding fifteen at once, where the flood would cost the reader the curated
additions in the same message, and two is not that.
The distinction the first version missed is which device the line names. An
adopted *device* collapses at any count because its line names a device that
did not exist before, which is itself the news. A vendor reading sits on a card
the user already has, so the card's name says nothing about what appeared on
it. Collapse now applies above five, per notification rather than per device
lifetime: five readings announced last month and one today is a one-line
update, not a flood.

Subject: [PATCH 102/345] fix(extension): four defects an adversarial review
found in b8
**Two lugs devices shared one identity.** The library paired both with the
`panel` subject, so two lugs declaring the same vendor property minted one
unique_id for two readings -- Home Assistant drops the second, and the survivor
shows whichever sorted first. Identical firmware on both lugs makes that the
expected case, not a coincidence. They are `kind="lugs"` keyed by direction
now, and `_SCOPE_PREFIX_BY_KIND` gives them their own scope while
`extension_device_identifier` still renders them on the panel's card: identity
must distinguish what placement merges.
**The cap could strand a user's enabled entity.** It admitted rows in adapter
emission order, which tracks the wire, so a firmware update declaring a
property earlier could evict a standing entity -- whose registry row is
permanent, and for which nothing would build an entity again. Unavailable
forever, stranger in its slot, no migration path by design. `adoptable` now
admits everything the registry already holds before capping the rest.
**The cap counted cards, not devices.** Panel, every circuit and both lugs
render on the panel's card, so thirty-five wire devices shared one allowance:
two vendor properties per circuit truncates a 32-circuit panel with no
misbehaving publisher anywhere. It counts `subject_key` now. The test that
claimed this behaviour only exercised battery-vs-panel and passed while the
code was wrong; it exercises the shared card now.
**Overflow was silent.** `MAX_PER_DEVICE`'s own docstring and the design both
promised a notice; the code logged, twice per setup, once per platform.
`async_notice_declined_extensions` raises a durable notice once at setup,
translated into all five locales.
Also clamps a vendor string to 255 characters rather than letting Home
Assistant raise on the state write.
The baseline reasons for `status/postal-code` and `status/time-zone` said
surfacing them would copy location into recorder history and duplicate what
Home Assistant owns. Both were written when surfacing meant a default-on
curated entity. They now surface as disabled vendor readings, where the
recorder cost is opt-in, so the reasons say what is now true: no curated
entity, which is a different decision from invisibility.
Requires span-panel-api 3.0.0b13 and span-panel-api-schema-1 0.1.0b10.

+same holds for `extension.py` and `snapshot.extension_properties`, for the same reason.
+
+## Extension properties
+
+A property on a device this integration **does** model — `battery-2/cell-temperature` hung off the BESS by a battery vendor. Until 2.1.0b7 it reached the user
+nowhere: it became a `DiscoveredMetadata` row and stopped at the diagnostics download. `extension.py` turns it into an entity on that device's existing card.
+
+### Where the value comes from
+
+The library carries it, in a type built for the purpose:
+
+| Type | Carries | Audience |
+| -------------------------------------------- | ----------------------------- | --------------------------- |
+| `DiscoveredMetadata` (`discovered.*` paths) | Declaration only, never value | Maintainer, via diagnostics |
+| `ExtensionProperty` (`extension_properties`) | Declaration **and** value | User, via entities |
+
+The same wire property appears in both, joined by its `{node}/{property}` path. **`ExtensionProperty` is deliberately not a `FieldMetadata`**: `partition()`
+walks `build_field_metadata()`, so a type that cannot enter that map has no path into a payload that leaves the machine. That is the diagnostics guarantee as a
+shape rather than as a rule somebody has to remember, and `test_extension_property_is_not_field_metadata` asserts it.
+
+`schema-1`'s `addressed_rows()` is shared by `build_discovery` and `build_extension_properties` so the two cannot disagree about what "unaddressed" means. A
+property counted as addressed by one and not the other would appear as an entity the diagnostics claim is ignored, or the reverse.
+
+### The identity, which is the irreversible part
+
+```text
+span_{serial}_adopted_{scope}/{node}/{property}
+```
+
+- **Anchored on what is stable and ours** — the panel serial and the curated scope (`bess`, `mid`, `pv`, `panel`, `evse_{node}`, `circuit_{id}`).
+- **Addressed by the wire path verbatim**, which is upstream's own capability-catalog spelling (`AdoptedProperty.path`, `discovery_path()`). Verbatim is what
+ makes it injective: the id _is_ the address. Normalising hyphens would collapse `battery-2` + `cell-temperature` and `battery` + `2-cell-temperature` into one
+ id, which `test_the_pairs_a_normalising_grammar_would_collapse_stay_distinct` pins.
+- **Never through `get_user_friendly_suffix`**, which de-_dots_ rather than de-hyphens and substitutes a curated suffix on a mapping hit.
+- **Not the eBus proxy composition.** `{proxier-id}-{proxied-id}` is upstream's device-handle spelling, and upstream states those handles are not identities:
+ they differ across enclosures and are unstable across the proxy-to-native transition. An id anchored on one would rename itself when a device stopped being
+ proxied, and nothing here migrates, so there would be no recovery.
+- An address outside the Homie charset (`[a-z0-9-]`) is **refused, not sanitised** — sanitising is what would make the slash-split ambiguous. It stays visible
+ in diagnostics.
+
+The slash distinguishes the two adoption grammars: device-level ids contain none.
+
+### Terminal identity
+
+An adopted extension is never promoted, re-sourced, re-homed or migrated. It changes only on an **external** trigger — the publisher stops publishing it, or
+better metadata arrives. Three consequences worth knowing before changing any of this:
+
+- **Curation is never blocked by one existing.** If a property is later curated, the curated entity is a _new_ entity with its own id and history; the adopted
+ one is not renamed into it. Ids are permanent, identity is not, and an earlier draft of this design built a registry take-over path to avoid that — it was
+ cut, because it rested on the library ceasing to emit the row in lockstep with curation, a two-repo promise whose conformance test cannot distinguish
+ "curation mapped it" from "the capture was regenerated without it".
+- **Nothing is ever removed by this integration**, and there is no engagement test anywhere. A row the user deletes is recreated — disabled — at the next setup
+ while the property is still published, so deletion is not suppression. It sticks exactly when publishing has stopped, because then nothing exists to recreate
+ it from. That is why no suppression feature exists: the delete button already means "hide until next reload" for a live reading and "clear it out" for a dead
+ one, decided by the wire.
+- **A property that stops being published reads unknown rather than disappearing.** Silence does not distinguish gone from not-yet-arrived.
+
+### What metadata may reshape, and what it may not
+
+| Attribute | Revisable later? |
+| ------------------------------------------- | --------------------------------------------- |
+| `entity_category`, device class, unit, name | **Yes**, freely — no id change, no statistics |
+| Platform (`sensor` vs `binary_sensor`) | **No.** The domain is baked into `entity_id` |
+| `state_class` | Never set at all |
+
+The free half is free _because_ of the never half: these entities carry no `state_class`, so they write no long-term statistics, so a later unit or device-class
+change has nothing to reinterpret. Contrast a curated entity, where changing a unit under a `state_class` is the unrepairable case.
+
+The platform is enforced in `resolve_platform`, not remembered: whatever domain the id is already registered under wins, however the declaration later changes.
+`async_update_entity` raises `ValueError("New entity ID should be same domain")`, so re-deriving the platform from better metadata would not move a row — it
+would strand it and mint a second entity beside it. `test_the_platform_a_row_is_born_under_is_the_one_it_keeps` is the guard.
+
+### Read-only, and why disabled-by-default does not gate it
+
+No switches, selects or number boxes, even where the panel declares the property settable — `classify_extension` is `adoption.classify` with its three control
+rows deleted. The worked bypass: a vendor publishes `acme/charge-limit` beside the curated EVSE limit. The curated number goes through
+`evse_charge_limit_payload()`, which **refuses** a value above the commissioned ceiling. An auto-generated number on the same device, fed by a generic set
+topic, publishes whatever the user types on the same wire. The islanding assertion is the same shape — schema_1 translates `GRID` into `ON_GRID`.
+
+"Disabled-by-default gates the control", which `classify` argues for unmodelled devices, does not transfer: there the hazard is user intent, here it is semantic
+interaction with curated logic the user cannot see. The library enforces it structurally — `ExtensionProperty` has no set-topic member to populate, and
+`set_adopted_property` still resolves only against `adopted_devices`.
+
+### The cap
+
+`MAX_PER_DEVICE` (60) bounds what one **wire device** may mint — counted on `subject_key`, not on the card. The panel, every circuit and both lugs render on the
+panel's card, so counting per card would pool thirty-five devices against one allowance and truncate a 32-circuit panel at two vendor properties each, with no
+misbehaving publisher anywhere. Overflow raises a durable notice (`async_notice_declined_extensions`, once at setup rather than once per platform), because a
+truncation the user cannot see is the one thing worse than the truncation: sixty of a device's eighty readings looks exactly like a device with sixty.
+
+**An id the registry already holds is never displaced.** The cap admits in adapter emission order, which tracks the wire, so a firmware update declaring a new
+property earlier shifts everything after it. Capping on arrival order alone would let a new property evict a standing entity — whose registry row is permanent,
+and for which nothing would ever build an entity again, leaving it unavailable forever with a stranger in its slot and no migration path by design. `adoptable`
+therefore partitions registered from new, admits every registered row, and applies the cap only to the rest. Registry rows are permanent here and nothing
+removes them, so a vendor node declaring hundreds of properties would otherwise put hundreds of rows in every entity picker on every install that met it, with
+no later release able to take them back. Deliberately far above any real device — the sixteen `pcs` properties are the largest curated example — so it is a
+backstop against a misbehaving publisher rather than a policy on normal ones.
+
+### The prominence hint
+
+`prominence_hint()` is advisory only: everything arrives `DIAGNOSTIC` regardless, and the hint rides along as an entity attribute for curation triage. Ranked by
+confidence, and the ranking is the argument:
+
+1. **Identity-family naming → detail.** Highest confidence because it is purely _negative_ — a property named for a vendor, model, serial, part number or
+ firmware build is device description.
+2. **A unit in `DEVICE_CLASS_BY_UNIT` → reading.** Moderate, and it may promote but never demote, because it fails systematically in one direction: the most
+ headline-worthy number a battery publishes is a `%` state of charge, and `%` is absent from that map on purpose, being equally a confidence or a duty cycle.
+3. **Everything else → detail**, with `node_has_curated_siblings` recorded as corroboration rather than as a decision. Homie nodes are organisational, not
+ editorial.
+
+The real fix is upstream: a declared `role` on the property, proposed in `SpanPanel_Docs/span/docs/dev/ebus-property-role-proposal.md`. Until then the ranking
+is the shipping plan, and `entity_category` being free to revise is what makes a conservative default cheap.

Subject: [PATCH 103/345] chore(deps): follow span-panel-api to its release
versions
span-panel-api 3.0.0, span-panel-api-schema-0 1.0.0 and span-panel-api-schema-1
1.0.0 replace the beta pins. Nothing about this integration's behaviour changes:
the libraries are the same code their last betas carried, renumbered for the
first public release.
The pins live in three files and all three move together. pyproject.toml is the
development environment, manifest.json is the list Home Assistant actually reads
at install time, and requirements_test.txt is derived from the manifest -- which
is not a fact worth remembering, because test_the_real_repository_is_in_sync runs
sync-dependencies and fails if any of them disagree. It caught the third file
here after the first two were edited by hand.
manifest.json now names versions that are not on PyPI yet, so the release order
is the libraries first -- v3.0.0, then schema-0-v1.0.0 and schema-1-v1.0.0 --
and this integration afterwards. Until then the editable [tool.uv.sources] paths
supply them, which is what the local lock resolves.
Home Assistant pins are deliberately untouched. homeassistant 2026.8.0,
homeassistant-stubs 2026.8.0 and pytest-homeassistant-custom-component 0.13.354
already agree with each other and with the 2026.8.0 floor hacs.json declares, and
the floor is the version worth testing against: it is the oldest one a user can
be running, while the newest is only where developers drift.

Subject: [PATCH 104/345] fix(naming): circuit energy descriptors match the
suffixes they ship with
The display names and the entity-id suffixes for circuit energy sensors
disagreed on word order: name="Produced Energy" against a suffix of
energy_produced, and the same for consumed and net. Nothing surfaced it while
this integration assembles entity ids itself, because the two never meet -- the
id comes from the suffix mapping and the name is only a label.
They meet the moment Home Assistant composes the id from the name, which is what
core 2026.8's entity_id_parts does. Composition would slugify "Kitchen Produced
Energy" to kitchen_produced_energy while the entity has shipped as
kitchen_energy_produced since before 2.0.8, and "Recreate entity IDs" would then
offer to reorder the suffix of every circuit energy sensor on the panel -- three
per circuit, 96 on a fully mapped 40-space install. Those offers say nothing
about the circuit names a user set in the SPAN app, which are identical on both
sides; they are purely our own two spellings disagreeing.
So the names move to the ids rather than the other way round. Verified: every
descriptor in CIRCUIT_SENSORS and UNMAPPED_SENSORS now slugifies to exactly the
suffix get_user_friendly_suffix returns for it, through the api_key_mapping in
SpanCircuitEnergySensor that resolves circuit_energy_produced to
producedEnergyWh.
Nothing structural moves. unique_id is built from description_key and never
reads a name, so it is byte-identical and stays single-form and predictable,
which is what a future migration depends on. Entity ids are untouched. What does
change is user-visible: cards read "Kitchen Energy Produced" rather than
"Kitchen Produced Energy". Panel-level descriptors are left alone -- they
already match their own suffixes (main_meter_produced_energy), which are
noun-last, so the two levels necessarily read differently. That asymmetry is
inherited from the ids, not introduced here.
This is a precondition for adopting core's composition rather than a change that
stands on its own; taken alone it is a relabel.

Subject: [PATCH 105/345] chore(deps): pin span-panel-api 3.0.1
The manifest is the pin that reaches a user; `sync-dependencies` propagated it
to pyproject.toml and requirements_test.txt. The schema adapters stay at 1.0.0 --
only the bootstrap moved.
`uv.lock` is unchanged, and that is not an oversight: `[tool.uv.sources]` points
span-panel-api at the local worktree, and uv lets a path source override the
version specifier rather than checking against it. Local development therefore
resolves to whatever that worktree holds, pin or no pin. CI strips the sources
block and re-locks from PyPI, which is the only place this specifier is enforced.

Subject: [PATCH 106/345] chore(deps): point the local sources at the primary
checkout
The library half of this branch merged and released, so the `-p3` worktree these
paths named is gone. A missing path source is not a soft failure -- `uv run`
cannot build the environment, so nothing in the repo runs until it is corrected.
Repointing also lets the 3.0.1 pin resolve: the lock now records span-panel-api
3.0.1 from the primary checkout instead of 3.0.0 from a worktree that no longer
exists. The Pyright extraPath moved with it.
CI never reads this block -- it strips `[tool.uv.sources]` and re-locks from PyPI
-- so a stale path here breaks local work only.

Subject: [PATCH 107/345] fix(naming): Recreate entity IDs proposes what the
panel says now
Renaming a circuit in the SPAN app left "Recreate entity IDs" offering the
entity its own ID, so the button appeared to do nothing (#252).
The registry generates an ID from the user's `name` override, else
`suggested_object_id`, else `object_id_base`. Friendly-names mode writes no
registry `name` -- the panel name arrives as `original_name` -- so the
suggestion decides, and `construct_single_circuit_entity_id` was handing back
the entity's stored ID on every reload. The suggestion was therefore frozen at
whatever the circuit was called the day it was added.
It now computes the ID from current panel data and the naming flags, for
existing entities as much as new ones. That cannot move a live entity ID: an
entity_id set before add is only a suggestion, and for a unique_id already on
file `async_get_or_create` routes to `_async_update_entity` with no
`new_entity_id` before `entity.entity_id` is reassigned from the stored entry.
Unique IDs are untouched -- they derive from the description key and never read
a name.
Circuit-numbers mode is deliberately unchanged, guarded by a test. There the
registry `name` phase 2 sync writes is both what shows the panel's name in the
UI and what outranks the suggestion, so Recreate keeps composing from that name.
Correcting it would mean rerouting phase 2 sync, which is a product decision,
not part of this fix.
The registry lookup was the only use of the `unique_id` argument, and
`existing_entity_id` the only use of that parameter on `_construct_entity_id`;
both are gone rather than left as parameters that no longer decide anything.
Every test reloads before asserting -- asserting straight after creation
exercises the first-add path, where the suggestion is trivially current and the
bug cannot appear. The three that demonstrate the bug fail on the previous code;
the five guards pass on both.

+"""Recreate entity IDs proposes the ID the current panel data would produce.
+
+Issue #252: renaming a circuit in the SPAN app left "Recreate entity IDs" (the
+HA registry's `async_regenerate_entity_id`) proposing the entity's own ID, so
+the button appeared to do nothing.
+
+The registry generates an ID from three fields in priority order: the user's
+`name` override, then `suggested_object_id`, then `object_id_base`. In
+friendly-names mode this integration never writes a registry `name` -- the
+panel name reaches the UI through `original_name` -- so `name` is None, the
+generator short-circuits to `suggested_object_id`, and that field is whatever
+was suggested when the entity was first added. It was frozen because the
+integration preset the entity's *stored* ID on every reload, suggesting the
+value already in place.
+
+Every case here reloads before asserting. Asserting straight after creation
+tests the first-add path, where the suggestion is trivially current and the bug
+cannot appear.

Subject: [PATCH 110/345] fix(naming): keep the entity-id suffix an install
already has
Recreate offered 74 renames on a real panel after the previous beta: every
circuit energy sensor, `_consumed_energy` to `_energy_consumed`. Only one of the
74 was a circuit the owner had renamed, and that one was buried.
Installs predating the point where the suffix mapping reached entity ids took
their id from the descriptor name, so they carry `_consumed_energy` while their
own unique id carries `_energy_consumed`. The two have disagreed all along;
recomputing the suggestion is what made the disagreement visible.
The descriptor rename is not the cause and reverting it would not have removed a
single offer: in friendly-names mode the registry holds no `name`, so
`suggested_object_id` -- our suffix-based preset -- outranks `original_name` and
the descriptor name never reaches the id. Measured both ways; the proposal is
`_energy_consumed` either way.
So an existing entity keeps the suffix it shipped with and only the circuit-name
half of its id follows the panel. `LEGACY_ENTITY_ID_SUFFIXES` records the older
spellings; comparing with the suffix removed means a renamed circuit still gets
the computed id, which is the whole point of #252. A trailing segment that merely
looks like a suffix change -- "Kitchen Outlets" renamed to "Kitchen" -- is a
rename and is still offered.
`_construct_entity_id` takes `existing_entity_id` again. It no longer decides
whether to compute an id, only which suffix the computed one carries.
Four tests, two of which fail with preservation disabled. The earlier ones all
built their entities with current code, where preset and live id are the same
string by construction and this could not appear -- which is why it reached a
beta.

Subject: [PATCH 111/345] fix(naming): stop the registry name deciding
circuit-numbered entity ids
Recreate in circuit-numbers mode proposed a friendly-name id for a
circuit-numbered entity, so accepting it converted the whole panel to the naming
the mode exists to avoid. Pre-existing -- it shipped in b9 and everything before
-- but only reachable now that Recreate works at all.
`suggested_object_id` was always correct in that mode. It was outranked: phase 2
sync wrote the panel's name into the registry's `name`, and
`_async_get_full_entity_name` reads the suggestion only when `name` is None
(entity_registry.py:513). One field was doing two jobs, and the second was
invisible.
The name now travels as `original_name`, which becomes `object_id_base` and ranks
below the suggestion, so it reaches the UI without touching the id. Clearing it
alone does nothing -- measured, the old sync writes it straight back on the same
load -- so the write had to stop as well.
No migration pass. The six sites that wrote the name already look up their own
entity and already hold the ownership test, so each releases the field as its
entity loads: idempotent, self-healing, and only ever touching a name this
integration wrote. A name the user set fails that test and is left alone, keeping
today's behaviour for those entities.
Both modes now share one naming path -- `_attr_name` from the panel, registry
`name` never written -- leaving the entity_id preset as the only difference
between them, which is the only thing they are supposed to differ in.
Costs, both measured and recorded in the spec: a rename in the SPAN app refreshes
the display at reload rather than in place, and `friendly_name` gains the device
prefix that friendly-names mode already carries. Neither the SPAN card nor a
device page shows the prefix -- both strip it.
Six new tests, four of which fail on the previous code. Eight existing tests
asserted the old scheme and now assert the new one.

Subject: [PATCH 112/345] docs: correct the 2.1.0 notes and the adoption
docstring
adoption.py claimed "the unit of adoption is a device, never a property"
and argued against ever minting an entity for a property on a modelled
device -- which extension.py has done since it shipped. It now states the
split between the two modules and why a settable property becomes a
control on an adopted device and a reading on a curated one.
The five sensors disabled for SPAN API defects repeated the same
eight-line note at each site. One paragraph in the module docstring names
all five; each site keeps a one-line pointer to #234, which is now the
pinned tracking issue for them.
CHANGELOG, 2.1.0 only:
- Every entry trimmed to at most two sentences, and the four entries
covering "Recreate entity IDs" collapsed into one line stating the
fixed behaviour rather than the sequence of beta fixes.
- Three entries corrected against the code: circuit and lugs vendor
readings land on the panel's card rather than a card of their own; the
new-entity notification collapses an adopted device, and any card
gaining more than five vendor readings, into a line with a count; and
the controls-vs-readings bullets now name their subject, since adopted
devices do get switches and selects while extensions never do.
- Dropped the Grid Forming Entity entry: resolve_dominant_power_source
preserves the value space deliberately, so nothing observable changed.
- Spelling and grammar.

## [2.1.0] - 8/2026
-### You will need this release when SPAN updates your panel
+### You will need this release before SPAN updates your panel
SPAN firmware `r202633` replaces the way the panel publishes its data — the wire model every release up to 2.0.8 is retired in the same update that introduces
the new one. There is no wire overlap and no setting to keep the old behaviour. **2.0.8 cannot read a panel on `r202633`**: it stays connected, reports every
circuit as missing, and shows nothing useful.
-We do not control when that update reaches you, and the schedule belongs exclusively to SPAN. Panels update on SPAN's timing, not on yours or ours. A mandatory
-upgrade that keeps working therefore demands a release that can adapt on connection, and adapt again as necessary. If uninterrupted integration matters to you,
-be on this release **before** your panel changes — afterwards you are looking at a blank integration while you work out why.

-**The transition itself is seamless.** Install 2.1.0 early and your only outage is the firmware update itself. When your panel changes over, the integration
-notices on the wire, reloads itself, notifies you, and carries on — no reconfiguration, no re-pairing, no lost history. Your entities keep their entity ids,
-their unique ids and their statistics across the change. New things appear because the new firmware publishes a bit more and because devices appropriate to your
-install are added; nothing you already had goes away. A log line and a one-time notification tell you exactly what happened, so take a screenshot. If you

**A panel that is still rebooting is waited out, for as long as your panel takes.** Taking the firmware upgrade drops the panel's connection for several minutes
-— four or more is not uncommon once the panel receives its upgrade file. The integration keeps checking until the panel answers properly.
-
-**Your energy history is unaffected by that wait.** Energy sensors hold their last reading through an outage for the grace period you configure (fifteen minutes
-by default), which is what stops a gap becoming an `unknown` and a spike in your statistics.
-
-**A firmware upgrade that adds a capability reloads as well**, so hardware your panel starts reporting — the Microgrid Interconnect Device, the shed forecast,
-the power control system, battery telemetry, DER link health — turns into entities when it appears rather than at your next restart.
-
-**If following the upgrade ever fails for some other reason, you are told what to do about it**: plainly, that a reload is needed once the panel is back up,
-rather than a bare error in the log while the integration carries on reading the panel with the wrong reader.

### Changed
-- **`DSM Grid State` is now more trustworthy.** It keeps its entity id and all of its history. Previously it was _inferred_ — from the battery if one was
- fitted, otherwise from the dominant power source and whether power was crossing the grid connection. It now reads the islanding state the Microgrid
- Interconnect Device actually senses.
-- **`Grid Islandable` keeps working** across the upgrade. The new firmware publishes no panel-level islandable property — it makes the question structural
- instead, where the presence of a Microgrid Interconnect Device is what says a panel can island — so the entity now reflects whether that device is present. A
- panel without one reads `Off`, which is an answer, rather than going unavailable.
-- **`Grid Forming Entity` keeps working** across the upgrade too. Your panel used to publish a source class outright; the new firmware names the forming
- _device_, and it names it on the Microgrid Interconnect Device, which a panel without a battery does not have. On such a panel the answer is settled by what
- cannot be there — a battery needs that device, a solar inverter cannot form a grid on its own, and a panel supplying nothing is not publishing — so the entity
- reads `Grid`, which is exactly what your panel reported before.
+- **`DSM Grid State` is now more trustworthy**, reading the islanding state the Microgrid Interconnect Device actually senses rather than inferring it from the
+ battery, the dominant power source and which way power was crossing the grid connection. It keeps its entity id and all of its history.

+ instead, so the entity now reflects whether a Microgrid Interconnect Device is present. A panel without one reads `Off`, which is an answer, rather than going
+ unavailable.
- **Battery model** may read differently after upgrading: the new firmware separates the human-readable designation from the SKU, and this entity now shows the
designation. The normalisation happens in the library on both sides of the upgrade, so it lands once, at this release, rather than unpredictably when your
panel changes over.
-- **Five panel sensors are switched off for new installations, because the eBus specification's own maintainer has documented that their values cannot be relied
- on.** A conformance note for SPAN firmware r202633 identifies three defects in what the panel publishes, all of which predate that release: the feedthrough
- (downstream lugs) energy registers are computed from two unrelated counters and can decrease or go negative — on a panel with no feedthrough load they report
- roughly whole-panel figures where the truth is zero — the feedthrough power reading is inverted relative to every other terminal, and the feedthrough currents
- report the _upstream_ service conductors rather than a downstream measurement. The affected entities are **Feedthrough Produced Energy**, **Feedthrough
- Consumed Energy**, **Feedthrough Power**, and the two **Downstream** current sensors.
-- **If you already have those five, nothing changes and they stay exactly where they are.** Home Assistant consults the enabled-by-default setting only when an
- entity is first created, so an existing installation keeps them, keeps its history and keeps its entity IDs. This stops new installations picking them up; it
- cannot reach back. If you use any of the five on a dashboard or in an automation, they are worth removing — but that is your decision to make, not something
- an upgrade should do to you.
-- **Your other panel readings are unaffected, and that is now checked against a real panel rather than assumed.** A capture from a live upgraded panel arrived
- alongside the conformance note: the panel's four power-flow values sum to zero exactly, and the battery power sensor's definition is byte-for-byte what 2.0.8
- shipped. The upstream lugs, the main panel meter and every circuit are in the correct frame, as is the power-flow group, which the specification has now been
- corrected to describe the way the panel has always published it.
-
-- **New entities are now announced in a notification that names them — whether or not they arrived switched on.** Previously only entities added _disabled_ were
- mentioned, on the reasoning that an enabled one is already visible in your entity list and its history. That is only true if you are watching your entity
- list, which nobody is: an addition that breaks nothing was indistinguishable from no addition at all. The notification names every entity that was added,
- splits them by whether they are ready to use or still switched off, and tells you where to turn the switched-off ones on.
-- **It is a notification rather than a Repair, because an addition is not a repair.** Nothing is broken and nothing needs fixing. Any new-entity item still
- sitting in your Repairs list from a previous version is removed on upgrade.
-
-- **The Wi-Fi network name moved to the Wi-Fi Link sensor**, which is where you would look for it: the entity that tells you whether Wi-Fi is up now also tells
- you which network it is up on, as a `wifi_ssid` attribute. It is absent rather than blank on a panel that publishes no SSID.
-- **It is no longer an attribute of the Software Version sensor.** A network name on a firmware-version sensor never made sense — it sat there because
- `panel_size` was already in that attribute block. If you have a template reading `state_attr('sensor.span_panel_software_version', 'wifi_ssid')`, point it at
- the Wi-Fi Link binary sensor instead. `panel_size` is unaffected and stays where it is.
-
-- **The three circuit energy sensors are renamed to match the ids they are given.** "Produced Energy", "Consumed Energy" and "Net Energy" become **Energy
- Produced**, **Energy Consumed** and **Energy Net**, the order used by the `energy_produced`, `energy_consumed` and `energy_net` suffixes that these sensors'
- unique ids carry and that new entities are given. **Entity ids, unique ids and history are unchanged**; only the name shown in the UI reorders.
+- **Five panel sensors are switched off for new installations** (#234), because the SPAN API documented three defects that predate SPAN firmware r202633: the
+ feedthrough energy registers can decrease or go negative, the feedthrough power reading is inverted relative to every other terminal, and the feedthrough

+
+- **New entities are now announced in a notification, whether or not they arrived switched on.** The notification now splits what arrived into ready to use and
+ switched off and names each entity.
+
+- **The Wi-Fi network name attribute moved to the Wi-Fi Link sensor**, which is where you would look for it: the entity that tells you whether Wi-Fi is up now
+ also tells you which network it is up on, as a `wifi_ssid` attribute. It is absent rather than blank on a panel that publishes no SSID.
+- **It is no longer an attribute of the Software Version sensor**, where a network name never made sense attribute block. If you have a template reading
+ `state_attr('sensor.span_panel_software_version', 'wifi_ssid')`, point it at the Wi-Fi Link binary sensor instead.
+
+- **The three circuit energy sensors are renamed to match the ids they are given**: "Produced Energy", "Consumed Energy" and "Net Energy" become **Energy

### Fixed
-- **Recreate entity IDs proposes the ids your panel would produce now.** Renaming a circuit in the SPAN app used to leave the button offering each entity the id
- it already had, so it looked like it did nothing (#252). The proposal was frozen at whatever the circuit was called when the entity was first created; it now
- follows the panel. **It is still an offer you accept** — a rename in the SPAN app never moves a live entity id by itself, and unique ids and statistics are
- untouched. Circuit-numbers installations are unchanged: there the display name written by name sync is also what Home Assistant builds the proposal from, so
- the button behaves exactly as it did.
-- **Recreate entity IDs no longer offers to convert a tab-named panel to friendly names.** In Tab Based Names mode the button used to propose
- `sensor.span_panel_air_conditioner_power` for a live `sensor.span_panel_circuit_15_power` — accepting it undid, for every circuit at once, the one thing that
- mode exists to provide. It now proposes the tab-based ID the entity already has, so Recreate is a no-op unless a breaker actually moved.
-- **Names still follow your panel in that mode**, and still stop at a name you set yourself. What changed is where the name is kept: in a field that describes
- the entity rather than the one Home Assistant reads when it builds an entity ID. A name written by an earlier release is handed back the first time each
- entity loads — nothing to run, nothing to confirm. **One consequence:** a circuit renamed in the SPAN app now updates the display after the integration
- reloads, a few seconds rather than immediately, which is what Circuit Friendly Names mode has always done.
-
-- **Only circuits you actually renamed are offered.** Installations old enough to predate the current suffixes carry entity ids ending `_consumed_energy`,
- `_produced_energy`, `_net_energy` or `_current_power`, where an entity created today would end `_energy_consumed`, `_energy_produced`, `_energy_net` or
- `_power`. Those ids keep the suffix they have. Renormalising them would have offered a rename for **every circuit on the panel** — seventy-four on one we
- measured — burying the one circuit that had actually been renamed and breaking the dashboards and automations of anyone who accepted.
+- **Recreate entity IDs proposes the ids your panel would produce now** (#252), in your installation's naming style; unique ids and statistics are untouched.
- **Enum sensors advertise the states they can actually report.** Nine sensors declared only `unknown`, so `DSM Grid State` sitting at `On Grid` showed
"Possible states: Unknown".
-- **The README described Battery Power's sign backwards.** The sensor reports **discharging** as positive and always has — that is what release 2.0.5
- established (#184) and what a measured panel confirms. **No entity changed and no reading moved**; only the documentation was ever wrong.

| **Replaced sub-device shows the old serial number** | After replacing a SPAN sub-device (Drive / EVSE, BESS, PV inverter), the device entry in Home Assistant keeps showing the previous hardware's serial number. The integration keys entities off the panel-assigned node identity, which is intentionally stable across hardware swaps so long-term history (e.g. lifetime charging kWh for a Drive) is preserved. The device-registry serial number, however, does not auto-refresh. | In**Settings → Devices & Services → Span Panel**, open the affected sub-device and delete it, then reload the integration (or restart Home Assistant). The device re-registers with the new serial number. Entity IDs and their recorded history are preserved. |
| **Door sensor unavailable** | The SPAN API returns UNKNOWN if the cabinet door has not been operated recently. This is a defect in the SPAN API. | The integration reports the sensor as unavailable until a proper value arrives. Opening or closing the door publishes the correct state. The door is classified as a tamper sensor (`Detected` / `Clear`) to differentiate it from a normal entry door. |
| **No switch on a circuit** | A circuit has no switch entity exposed in Home Assistant. | The circuit is configured in the SPAN App as one of the "Always on Circuits". The API does not permit user control of those circuits, so no switch is created. |
+| **Reinstalling to change the entity ID style gives back the old entity IDs** | The naming style is chosen at install and cannot be changed from the options, so reinstalling looks like the way to switch. It is not: every entity returns with the entity ID it had before. | Home Assistant remembers a removed entity for **30 days**, keyed on its unique ID, and restores that record's entity ID — along with its name, area, labels and icon — as soon as an entity with the same unique ID appears again. This integration's unique IDs do not change with the naming style, so the remembered ID wins over the one the new style asks for. Either clear the leftover registry entries between removing and reinstalling, or wait out the 30 days and let Home Assistant discard them. A tool such as [ha-registry-clean](https://github.com/LegoTypes/ha-registry-clean) can do the clearing; it is a separate project, not part of this integration. Clearing also discards the names, areas and labels you had assigned. |

Subject: [PATCH 116/345] fix(translations): move notification strings out of
the hassfest-validated files
hassfest validates strings.json and translations/en.json against Home
Assistant's own schema and rejects any key it does not define, so the
`notifications` section those files carried failed the check outright --
"extra keys not allowed @ data['notifications']". That is what an
unsupported custom category looks like from the outside, and it is the
same fact notices.py already documents as its reason for reading these
strings itself rather than through homeassistant.helpers.translation.
The strings move to a notifications/ directory beside translations/, one
file per language, so hassfest sees only the categories it defines and
the notices keep their per-language files. read_translations reads the
new directory; its language-chain fallback is unchanged.
sync_translations.py validates the new directory the way it validates
translations/, against notifications/en.json instead of strings.json --
without that these five files would have silently lost the key-parity
guarantee the move was supposed to preserve. Verified by removing a key
from the French file and watching the hook fail.
1269 tests passing; full prek set green.

Subject: [PATCH 117/345] fix(select): gate the priority select on priority
settability, not the relay
The shed-priority select was created for every circuit whose relay is
user-controllable, which is a different commissioning flag from the one that
governs whether priority can be written at all.
Under v1.0 a panel expresses never-backup as the absence of `$settable` on
`load-shed/priority`, and the adapter carries that as `is_never_backup` --
independent of `switch/relay-controllable`, which it carries as
`is_user_controllable`. SPAN's migration guide is explicit that the flat
booleans consolidate per-property rather than per-combination, so the two are
free to disagree.
Using the relay flag as a proxy meant offering a priority control on a circuit
whose priority the panel refuses to change. `is_never_backup` was parsed,
carried on the snapshot, and read nowhere in this integration.
Conservative on purpose: the existing relay gate stays, so no circuit gains a
select and no entity is added. Whether a relay-locked circuit should show a
priority select -- its priority is settable but inert, since a locked relay is
exempt from shedding -- is a separate question this does not answer.
The panels we have captures from declare every circuit's priority settable, so
the new test drives the flags directly rather than a wire fixture.

Subject: [PATCH 118/345] feat(websocket): carry priority settability, and pin
the circuit record
The topology record told a consumer whether the relay could be commanded but
not whether the priority could be written. Those are two independent
commissioning flags: a never-backup circuit has a working relay and a priority
the panel pins, so relay controllability is not a usable proxy for it in either
direction.
That gap has a consumer. The card decides whether to render a circuit's
shedding priority from whether a select entity exists, which is an
entity-existence check standing in for a semantic question this integration
owns -- so c65ef64, which stopped creating a select for a circuit whose
priority is pinned, also stopped the card rendering that circuit's priority,
in a repository no test here can reach. `is_never_backup` is carried now so
that decision can be made from the fact rather than inferred from an artifact
of it.
The record's key set is pinned by a test for the same reason: a consumer
outside this repository renders from these keys, so adding or removing one is
a contract change and should fail here rather than surface as a rendering
change somewhere else. Both new tests were mutation-verified -- dropping the
key fails them.
No entity or platform behaviour changes.

Subject: [PATCH 119/345] security: stop persisting the panel passphrase, add
rotate_credentials
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Three independent pieces of the security-hardening work that do not depend
on span-panel-api 3.1.0.
**The panel passphrase is no longer stored.** It is an input to registration
and nothing afterwards reads it back — the only read anywhere was
diagnostics redacting it. A stored copy buys nothing and can mint fresh
panel credentials at any time, so it is no longer written to the config
entry, and a v6→v7 migration pops it from entries that already carry one. A
reauth on an unmigrated entry drops it too, and the flow no longer keeps a
copy in memory for the life of the flow.
Both version constants move to 7. `CURRENT_CONFIG_VERSION` drives the
migration body, but it is `SpanPanelConfigFlow.VERSION` that Home Assistant
compares against `entry.version` to decide whether to call
`async_migrate_entry` at all; bumping only the first would leave the
migration as dead code that a hand-built v6 entry would still appear to
exercise. A test goes through `async_setup` so the two cannot drift apart.
`CONF_HOP_PASSPHRASE` stays in `const.py` and in the diagnostics redaction
tuple — it is the key the migration pops, and an unmigrated entry must still
be redacted.
**New action `span_panel.rotate_credentials`** asks the panel for a fresh
eBus MQTT broker password, stores it, and reloads the entry, for use after a
contractor visit or a suspected exposure. The previous broker password stops
working immediately, so every other local client using it has to be
re-provisioned; the description says so, because a user who runs this
without knowing will break their own tooling and have no idea why. Failure
paths leave the existing credentials untouched.
The admin check is explicit rather than `verify_domain_control`, which is
not an admin gate: it returns early for a call with no `user_id`, and
otherwise checks `POLICY_CONTROL`, which the default user policy grants
every non-admin. A contextless call is refused outright — an unattended
automation has no business rotating credentials.
**Documentation**: a README security section covering what the integration
stores, what rotation costs, and the deployment choices that actually bound
the panel's exposure — VLAN isolation, a locked enclosure, read-only Home
Assistant users, encrypted backups. Plus a troubleshooting entry and release
note for the one-way nature of the version bump: once an entry reaches
version 7, an older build refuses to load it.

+### What the integration stores
+
+Setting up a v2 panel exchanges your panel passphrase for two long-lived secrets, which are kept in the config entry (`.storage/core.config_entries`):
+
+- the **eBus MQTT broker password**, which grants control of every relay, circuit priority, islanding state and EVSE limit on the panel and its sub-devices, and
+- the **REST access token**, which grants panel management — client registration, FQDN registration and credential rotation.
+
+The **panel passphrase itself is no longer stored.** It is an input to registration and nothing afterwards reads it, but a stored copy could mint fresh
+credentials at any time. Upgrading migrates the config entry to version 7 and removes it; nothing else in the entry changes and no entity is affected. If you

+> **Downgrade note.** Once an entry has reached version 7, installing an older build of the integration will fail to set it up — Home Assistant refuses to load
+> a config entry whose version is newer than the installed integration supports. Restore a backup taken before the upgrade if you need to roll back.
+
+These are the limits of what the integration can enforce. Anything that already holds the broker password — including another integration running in the same
+Home Assistant process — talks to the panel directly and is not subject to Home Assistant's permission model at all.
+
+### Rotating panel credentials
+
+The `span_panel.rotate_credentials` action asks the panel for a new eBus MQTT broker password, stores it, and reloads the integration.
+
+```yaml
+action: span_panel.rotate_credentials
+data: {}
+```
+
+Run it after a contractor visit, a suspected credential exposure, or any event that put someone else in front of the panel.
+
+**Know the blast radius before you run it.** The previous broker password stops working the moment the panel issues the new one, so every other local client
+using it — a second Home Assistant instance, a script, third-party tooling — must be re-provisioned from the panel before it will reconnect. This integration
+re-provisions itself automatically; nothing else does. The panel access token and the panel passphrase are not changed.
+
+Only a Home Assistant administrator can run it, and it cannot be called from an automation or script: a call arriving without a logged-in user is refused
+outright. If the panel rejects the stored access token, reauthenticate the integration first — the existing credentials are left untouched on every failure
+path.
+
+### Recommended deployment
+
+The panel credential is a single all-or-nothing secret, and anyone standing at the panel can mint a fresh one with three presses of the door switch. Network
+topology and physical control of the panel are the real boundary; everything above is defense in depth behind it.
+
+- **Put the panel on its own VLAN**, with default-deny between VLANs, and allow only the Home Assistant host to reach it. The integration currently uses
+ `tcp/80` for the REST bootstrap and `tcp/8883` for MQTTS. Deny `tcp/9001` and `tcp/9002` (plaintext and WebSocket MQTT) from every source unless you are
+ actively using the SPAN Home on-premise UI.
+- **Use the IP address or an FQDN, not the `.local` name.** mDNS does not cross VLAN boundaries. The panel's IP is in its certificate SAN, so hostname
+ verification still works; for an FQDN, the integration registers it with the panel so the panel adds it to the SAN.
+- **If Home Assistant cannot be on the panel's VLAN**, put a reverse proxy on the panel's VLAN and restrict its inbound to the Home Assistant host. The proxy
+ holds no panel credential; it only relays. Note that MQTTS is a TCP stream, not HTTP — a plain HTTP reverse proxy covers the REST port only, and `tcp/8883`
+ needs a stream proxy (HAProxy, nginx `stream`, or Caddy's `layer4` plugin).
+- **Lock the panel enclosure.** The three-press proximity bypass hands out full credentials to anyone who can open the door; it is the equivalent of a printed
+ root password. This outranks every software control on this page.
+- **Put dashboard-only household members in Home Assistant's read-only group.** Home Assistant's default user policy grants every non-admin user control of
+ every entity, which includes this integration's circuit switches and priority selects.
+- **Encrypt your Home Assistant backups.** An unencrypted backup contains `.storage/core.config_entries`, and the panel credentials in it are in plaintext.
+- **Enable multi-factor authentication on Home Assistant** and do not expose its API directly to the Internet. A compromised Home Assistant administrator
+ account is a compromised panel.

This integration's unique IDs do not change with the naming style, so the remembered ID wins over the one the new style asks for. Either clear the leftover registry entries between removing and reinstalling, or wait out the 30 days and let Home Assistant discard them. A tool such as [ha-registry-clean](https://github.com/LegoTypes/ha-registry-clean) can do the clearing; it is a separate project, not part of this integration. Clearing also discards the names, areas and labels you had assigned. |

The device-registry serial number, however, does not auto-refresh. | In**Settings → Devices & Services → Span Panel**, open the affected sub-device and delete it, then reload the integration (or restart Home Assistant). The device re-registers with the new serial number. Entity IDs and their recorded history are preserved. |
+| **Door sensor unavailable** | The SPAN API returns UNKNOWN if the cabinet door has not been operated recently. This is a defect in the SPAN API. | The integration reports the sensor as unavailable until a proper value arrives. Opening or closing the door publishes the correct state. The door is classified as a tamper sensor (`Detected` / `Clear`) to differentiate it from a normal entry door. |
+| **No switch on a circuit** | A circuit has no switch entity exposed in Home Assistant. | The circuit is configured in the SPAN App as one of the "Always on Circuits". The API does not permit user control of those circuits, so no switch is created. |
+| **Reinstalling to change the entity ID style gives back the old entity IDs** | The naming style is chosen at install and cannot be changed from the options, so reinstalling looks like the way to switch. It is not: every entity returns with the entity ID it had before. | Home Assistant remembers a removed entity for **30 days**, keyed on its unique ID, and restores that record's entity ID — along with its name, area, labels and icon — as soon as an entity with the same unique ID appears again. This integration's unique IDs do not change with the naming style, so the remembered ID wins over the one the new style asks for. Either clear the leftover registry entries between removing and reinstalling, or wait out the 30 days and let Home Assistant discard them. A tool such as [ha-registry-clean](https://github.com/LegoTypes/ha-registry-clean) can do the clearing; it is a separate project, not part of this integration. Clearing also discards the names, areas and labels you had assigned. |
+| **Setup fails after downgrading the integration** | After installing an older release, the SPAN Panel config entry fails to set up and Home Assistant reports an unsupported configuration version. | The release that stopped storing the panel passphrase migrated the config entry to version 7. Home Assistant refuses to load a config entry whose version is newer than the installed integration understands, and there is no automatic downgrade. Reinstall the newer release, or restore a backup taken before the upgrade. Removing and re-adding the integration also works and preserves entity IDs, but needs the panel passphrase or physical access to the door again. |

Subject: [PATCH 120/345] test(services): cover panel selection in
rotate_credentials
The `config_entry_id` branch and the runtime-data guard were the two
uncovered paths in the new service. The first is user-facing on any
multi-panel install; the second is the guard AGENTS.md requires.

Subject: [PATCH 121/345] build: span-panel-api 3.1.0, adapters 1.1.0
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
All five pins move together. The adapter pins are not incidental: the
library's write-then-verify needs a `ControlTarget` member on
`SchemaAdapter`, and `ADAPTER_CONTRACT_VERSION` rejects an adapter missing a
newly added method on that basis alone — so a partial bump fails adapter
discovery at runtime rather than at install.
Two consequences of the bump, both mechanical:
- The five setters return `PublishOutcome` instead of `None`, which breaks
`number.py`'s `set_fn` under strict mypy. The description-table signature
moves to `Awaitable[PublishOutcome]`; nothing consumes the outcome yet.
- `AsyncMqttBridge.publish` no longer takes `qos` from its caller — it is
fixed at 1 inside the transport, where the PUBACK is now awaited. Three
EVSE tests assert on that internal call and drop the argument.
The uv path overrides point at the `-security` worktree while 3.1.0 is
unpublished. Against the primary checkout, still on 3.0.1, the tests would
resolve the old library and pass without exercising any of this. CI deletes
that block and re-locks from PyPI, so CI cannot go green until 3.1.0 and both
1.1.0 adapters are published.

Subject: [PATCH 122/345] security: pin the panel's CA, and refuse to re-anchor
without a person
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The bridge previously fetched the panel's CA over unauthenticated plaintext
HTTP on every connect and trusted whatever came back, which is not a trust
anchor — it is whatever answered. 3.1.0 accepts a pinned PEM instead and
makes no CA request on any path once it has one.
**Acquisition.** New entries fetch the CA in the config flow, confirm the
certificate the panel actually serves chains to it, and show the fingerprint
for the user to accept. A CA that cannot validate the panel's own leaf is not
the panel's CA, and it is checked before the fingerprint is shown so nobody is
asked to accept a value that already failed. The step text says this is trust
on first use rather than implying verification the integration cannot perform.
Failure is not fatal. The user can retry or continue unpinned, and continuing
sets `panel_ca_pending`, which every later setup retries.
**Existing entries** take the same flag from the v7 migration, which does no
I/O — `async_migrate_entry` runs during startup, so a fetch there would delay
boot for an unreachable panel and a failure would have nowhere to recover to.
The deferred fetch logs at WARNING with the fingerprint, because it is an
accepted TOFU on the upgrade path and the user should be able to find the
value afterwards. v2 only: v1 fails setup before it reaches a panel and a
simulation entry has none.
**A changed CA raises a Repair and stops.** `SpanPanelCAChangedError` is
terminal on both paths — `ConfigEntryError` at setup, `UpdateFailed` in the
coordinator rather than the offline branch, which would keep serving the
snapshot read before the pin broke. The Repair carries both fingerprints
because the two remedies are opposite and only a person can choose between
them, and its fix flow re-fetches, re-shows and re-pins only on explicit
acceptance. Never auto-accepted: a rotated CA and an intercepted connection
are indistinguishable from here.
**The credential-bearing REST calls move onto the pin.** `PanelRestTransport`
resolves one entry's transport once — TLS port and a context from the pinned
PEM, or the plaintext port and Home Assistant's shared client. httpx fixes its
trust store at construction, so a pinned call cannot use the shared client and
the library builds its own; that cost is real and is why this is resolved in
one place rather than at five call sites. Reauth, reconfigure, FQDN
registration and `rotate_credentials` all take it. Initial registration cannot
— the anchor does not exist until later in the same flow.
`CONF_HTTPS_PORT` is prompted only when the HTTP port is non-default, since
that is the install most likely to be reaching the panel through something
that moved the TLS port too. It is needed: the library refuses an explicit
port 80 alongside a context rather than guessing which of the two readings
was meant.
Diagnostics gains the fingerprint and redacts the PEM, which is public but
multi-KB and would drown the dump.
Also fixes `check_fqdn_tls_ready`, which built its own SSL context and so kept
`VERIFY_X509_STRICT`. The panel's CA omits the Authority Key Identifier that
flag requires, so the probe could never succeed on Python 3.13+ and FQDN
registration always ran to its timeout. It now uses the library's builder,
which is the one place that workaround belongs.

Subject: [PATCH 123/345] security: gate control commands on who is asking, and
record every one
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Home Assistant's default user policy grants every non-admin user control of
every entity, and an automation calls services with no user at all. Neither
was distinguishable from an administrator at a breaker.
**The gate is split in two, because the two halves live in different places.**
Authorization needs caller identity, which exists only at the entity: core
sets `Entity._context` from the service call immediately before the handler
runs. Completeness needs a choke point, which exists only at the publish,
inside the library. So `SpanPanelEntity._async_guarded_control` binds the
caller to a `ContextVar` around one awaited call, and the decision is made in
the library's `ControlInterceptor`.
That is why there is no proxy on `coordinator.client`. A non-subclass proxy
would silently drop the BESS button, which is created behind an
`isinstance(coordinator.client, SpanMqttClient)` check, and a `__getattr__`
delegator returns `Any`.
The interceptor sees *every* control command, including one from a future path
that forgets the helper. Such a command arrives with an empty `ContextVar` and
is treated as contextless rather than permitted — fail-closed, and the reason
the decision is not in the helper itself.
`_context` is read explicitly rather than captured by overriding
`async_set_context`, which would inherit core's five-second
`CONTEXT_RECENT_TIME_SECONDS` staleness window and would fire for paths that
are not service calls.
**Four options, every default reproducing what an entry already does.** A
silent tightening on upgrade that breaks a household's automations is worse
than the status quo, and the user cannot diagnose it from the entity's error.
**The control lock** is the honest local substitute for a second factor, since
Home Assistant has no per-entity admin flag. Anyone may arm it; only an
administrator may disarm it, and a contextless caller never may, regardless of
`allow_contextless_control` — an automation that can unlock the panel is not a
lock. Auto-relock is evaluated on read so a suspended loop cannot skip it.
**`disabled` does not remove registry entries.** The entities stop being
created and read as unavailable; removing them would risk a regenerated
entity_id on the way back and discard the user's names and areas, which is the
breakage the project's hardest rule forbids.
**The audit** fires `span_panel_control_command` from `after_publish`, which
the library also fires for a veto — so the refusals cannot be silently missing,
which would make the audit worse than none. The refusal reason travels from
`before_publish` on a second `ContextVar`, readable there because the library
creates that callback's task from the same context.
All four `PublishState` members reach the audit and the logbook intact.
`ACCEPTED` and `UNCONFIRMED` are not failures: both were handed to the broker
and may already have been acted on, and `UNCONFIRMED` most often means the
value was already what was asked for. Only `FAILED` promises the command will
never be delivered, and only `FAILED` stops the switch adopting its optimistic
state — which now happens after the publish rather than before it, so a refusal
cannot leave a relay showing a position it never took, with no coordinator
update coming to correct it.
Relay debounce is per circuit and refuses rather than queues: a relay command
firing seconds later against a changed panel is worse than an error the
automation author can see.
The gate tests drive the interceptor directly. Every existing control test
assigns a mock client to `coordinator.client`, and a mock has no interceptor,
so a platform test proves nothing about the gate.

+"""Who may operate this panel through Home Assistant, and a record of who did.
+
+**What this is a boundary against.** Callers arriving through Home Assistant,
+and nothing else. It does not constrain anything holding the broker credential:
+a process with that credential publishes to the panel's broker directly and
+never reaches this code, and that includes a malicious or buggy custom
+integration running in the same Home Assistant process. Presenting this as a
+security boundary around the *panel* would be the most damaging thing it could
+do, because a user would stop looking for the real one — which is network
+topology and a lock on the enclosure. The README says so too.
+
+**Why it is split in two.** Authorization needs to know who is asking, and that
+is knowable only at the entity: Home Assistant sets `Entity._context` from the
+service call immediately before the handler runs. Completeness needs a single
+choke point, and that exists only at the publish, inside the library. So
+identity is captured at the entity into a `ContextVar` (see
+`SpanPanelEntity._async_guarded_control`) and the decision is made in the
+library's `ControlInterceptor`, which sees every control command including ones
+a future code path forgets to route through the helper. Such a command arrives
+with an empty `ContextVar` and is treated as contextless rather than silently
+permitted — that is the fail-closed default, and it is the reason the gate lives
+here rather than in the helper.

Subject: [PATCH 124/345] docs: the CA pin, the control options, and what none
of it protects against
Completes the documentation the earlier phases could not write, because the
features it describes did not exist yet.
The options table says what each one does *and* what it does not, in the same
row. The section that follows says the thing worth saying out loud: none of
this constrains something that already holds the broker credential, including
a custom integration in this same process reading it out of memory. A user who
believes otherwise stops looking for the real boundary, which is network
topology and a lock on the enclosure.
The frontend card is named rather than left to be discovered: its toggles call
`switch.turn_on` and `select.select_option` directly, so under `admin_only` a
non-admin gets a refusal with nothing on the card to explain it, and under
`disabled` the toggles point at unavailable entities.
Two troubleshooting entries. The CA-change repair walks through the decision
the user actually has to make, and says why the integration will not decide it
for them. The `unconfirmed` entry exists because the outcome looks like a
failure and is not: it usually means the value was already what was asked for,
and it is indistinguishable from a silent panel rejection only because SPAN's
firmware sends no reason code.

These are the limits of what the integration can enforce. Anything that already holds the broker password — including another integration running in the same
Home Assistant process — talks to the panel directly and is not subject to Home Assistant's permission model at all.
+### The panel's certificate authority
+
+The panel issues its own certificate authority and signs its TLS certificate with it. Setting up a panel fetches that authority, checks that the certificate the
+panel actually serves is signed by it, and shows you the SHA-256 fingerprint. From then on the integration accepts only that authority for both the MQTT
+connection and its REST calls, and stops rather than accepting a different one.
+
+**This is trust on first use.** The authority is fetched over your local network on a connection that has nothing to verify itself against — it is the anchor
+everything else is checked against — so a device sitting between Home Assistant and the panel could answer with an authority of its own and sign a certificate
+with it. What pinning buys you is that nothing can change afterwards without you being asked. If you can read the fingerprint from another source, such as an
+existing install of this integration on the same panel, compare it before accepting.
+
+Panels configured before this release are pinned on the first successful startup that reaches the panel, and that acquisition is logged at `WARNING` with the
+fingerprint so you can find the value afterwards. If the panel is unreachable the integration starts anyway and retries on the next startup; until it succeeds,
+the connection behaves as it did before.
+
+Diagnostics report the fingerprint under `panel_ca`. The certificate itself is not included — it is public, but multi-KB, and the fingerprint is the part worth
+reading.
+
+If your panel serves TLS somewhere other than port 443 — behind a reverse proxy, say — the setup flow asks for the port, but only when you have already changed
+the HTTP port from 80.
+
+### Restricting who can operate the panel
+
+Four options in **Settings → Devices & Services → Span Panel → Configure**. **Every one defaults to the behaviour your panel already has**, so upgrading changes
+nothing until you choose otherwise.
+
+| Option | What it does | What it does not do |
+| ------------------------------------------ | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------- |
+| **Who may operate the panel** | `Administrators only` refuses circuit switches, priority selects, the GFE override, EVSE limits and adopted controls from non-admin users. `Nobody` stops creating those entities altogether. | Neither affects sensors, and neither constrains anything holding the broker password. |
+| **Allow control without a logged-in user** | Turning it off refuses commands from automations, scripts and other integrations, which arrive with no user attached. | It cannot tell a well-behaved automation from a runaway one — only that neither has a user. |
+| **Control lock auto-relock** | Adds a switch that, while armed, refuses every control command. Anyone can arm it; only an administrator can disarm it, and never an automation. | It is not a password. It defends against misclicks and runaway automations, which is what a local control can actually do. |
+| **Relay debounce** | Refuses a second command to the same circuit's relay within the window. | It is per circuit, so an automation cycling many circuits still gets through. |
+
+**Why `Administrators only` is worth setting.** Home Assistant's default user policy grants every non-admin user control of every entity. Until you change this,
+a dashboard-only household member can open any breaker in the house.
+
+**What none of this defends against.** These options constrain callers arriving through Home Assistant. They do not constrain anything that already holds the
+broker credential — a second Home Assistant instance, a script you wrote, or a malicious custom integration running inside this same Home Assistant process,
+which reads the credential straight out of memory. For that, see [Recommended deployment](#recommended-deployment) below; network topology and a locked
+enclosure are the real boundary.
+
+**Nothing is deleted when you choose `Nobody`.** The control entities stop being created and read as unavailable; their registry entries, names, areas and
+customizations are kept, so turning the option back on restores exactly the entities you had. Dashboards and automations referencing them will show them
+unavailable in the meantime — including the shipped SPAN Panel card, whose toggles call `switch.turn_on` and `select.select_option` directly and have no
+card-side message for a refusal. A non-admin using that card under `Administrators only` gets a refusal with no explanation on the card.
+
+### The record of what was commanded
+
+Every control command fires a `span_panel_control_command` event and appears in the logbook, whether it succeeded, was refused, or never reached the panel. When
+there is no user — an automation — the originating automation or script is named instead, so an unattended write is attributed to _what_ rather than left blank.
+Every command is also logged at `INFO`.
+
+Commands report one of four outcomes, and the distinctions matter:
+
+| Outcome | Meaning |
+| ------------- | ---------------------------------------------------------------------------------------- |
+| `confirmed` | The panel reported the value you asked for. |
+| `accepted` | The broker acknowledged the message and the panel did not report a change. |
+| `unconfirmed` | Nothing came back within the deadline. **Not an error** — see the troubleshooting entry. |
+| `failed` | The command was never handed to the broker and will not be delivered. |
+| `refused:…` | This integration refused it, for the named reason. |

### Rotating panel credentials
The `span_panel.rotate_credentials` action asks the panel for a new eBus MQTT broker password, stores it, and reloads the integration.

| **No switch on a circuit** | A circuit has no switch entity exposed in Home Assistant. | The circuit is configured in the SPAN App as one of the "Always on Circuits". The API does not permit user control of those circuits, so no switch is created. |
| **Reinstalling to change the entity ID style gives back the old entity IDs** | The naming style is chosen at install and cannot be changed from the options, so reinstalling looks like the way to switch. It is not: every entity returns with the entity ID it had before. | Home Assistant remembers a removed entity for **30 days**, keyed on its unique ID, and restores that record's entity ID — along with its name, area, labels and icon — as soon as an entity with the same unique ID appears again. This integration's unique IDs do not change with the naming style, so the remembered ID wins over the one the new style asks for. Either clear the leftover registry entries between removing and reinstalling, or wait out the 30 days and let Home Assistant discard them. A tool such as [ha-registry-clean](https://github.com/LegoTypes/ha-registry-clean) can do the clearing; it is a separate project, not part of this integration. Clearing also discards the names, areas and labels you had assigned. |
| **Setup fails after downgrading the integration** | After installing an older release, the SPAN Panel config entry fails to set up and Home Assistant reports an unsupported configuration version. | The release that stopped storing the panel passphrase migrated the config entry to version 7. Home Assistant refuses to load a config entry whose version is newer than the installed integration understands, and there is no automatic downgrade. Reinstall the newer release, or restore a backup taken before the upgrade. Removing and re-adding the integration also works and preserves entity IDs, but needs the panel passphrase or physical access to the door again. |
+| **"SPAN Panel certificate authority changed" repair** | The integration has stopped connecting and a repair reports two fingerprints: the one it pinned and the one the panel now advertises. Entities are unavailable. | The panel is presenting a different certificate authority than the one you accepted at setup. Two things look identical from here and only you can tell them apart: a firmware upgrade or a factory reset rotates the authority legitimately, and so does a device on your network standing in for your panel. **If you know why it changed**, open the repair, compare the new fingerprint, and accept it — that re-pins and reconnects. **If nothing should have changed**, do not accept. Check what else is on the panel's network segment first. The integration will not reconnect on its own and will not re-pin on its own, deliberately: retrying would mean waiting to succeed against whatever is answering. |
+| **A control reports `unconfirmed`** | The logbook or the `span_panel_control_command` event says a command was `unconfirmed`. Nothing appears broken. | **This is not an error.** It means the panel took the command and did not report a change within the deadline, and the most common reason by far is that there was no change to report — the relay was already open, the priority was already that value. It is also indistinguishable from a silent rejection by the panel, because SPAN's firmware sends no reason code; the integration reports what it observed rather than guessing. The two outcomes that do mean something went wrong are `failed`, which means the command was never sent, and `refused:…`, which means this integration refused it and names why. |

Subject: [PATCH 125/345] security: pin the CA before registering, so the
passphrase is never sent in clear
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
I2 pinned the CA after authentication, which left the one exchange most worth
protecting outside the pin. `register_v2` sends the panel passphrase and
returns both the access token and the broker password — the highest-value
message on the network — and it was still going out over plaintext HTTP on
every new install. The parent spec's stated benefit, "removes passphrase/token/
broker password from cleartext LAN", was therefore true of reauth and steady
state and false of first contact.
Nothing forced that order: `GET /api/v2/certificate/ca` is unauthenticated. The
flow now fetches the CA, proves the panel's own leaf chains to it, shows the
fingerprint for acceptance, and only then offers the authentication menu —
with `register_v2` running over the accepted anchor. Reauth is unchanged; it
already adopts the pin its entry carries.
**The step text says what this does and does not buy.** Pinning before
registering closes the passive listener, which is the common case. It does not
close a device actively standing between Home Assistant and the panel at that
first fetch, which could answer with an authority of its own and still read the
exchange. Comparing the fingerprint out of band is what closes that, and is why
it is shown rather than accepted silently. Claiming the exchange is simply
protected would be worse than claiming nothing.
**The "continue without pinning" option is gone from the create path.** It was
defensible when the CA was acquired after registration and nothing further
depended on it. It is not defensible now: the very next thing the flow does is
send the passphrase, so an opt-out would quietly restore the plaintext exchange
this reordering exists to remove, at the moment a user is least likely to weigh
it. A failure is an actionable flow error instead, and resubmitting retries the
fetch — the recovery a briefly unreachable panel actually needs. Entry creation
raises rather than defaulting if it is somehow reached with no pin.
`panel_ca_pending` is now set only by the migration. An upgraded entry
exchanged its credentials long ago and nothing crosses the wire at its setup, so
starting unpinned and retrying costs nothing; a new entry has no such excuse and
cannot be created without a pin.

Mas um equipamento que neste momento se interponha activamente entre o Home Assistant e o seu painel poderia ter respondido com uma autoridade própria, e continuaria a vê-las.\n\nComparar esta impressão digital com outra origem é o que fecha esse caso, e é por isso que é mostrada. Outra instalação desta integração ligada ao mesmo painel indicará o mesmo valor."

Subject: [PATCH 126/345] docs: correct why an unpinned upgraded entry is
allowed to start
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The reasoning rested on a false claim. It said nothing crosses the wire at an
upgraded entry's setup; something does. The MQTTS session authenticates with the
broker password, and with `ca_pem` absent the library falls back to fetching the
CA over unauthenticated plaintext HTTP on every connect and trusting whatever
answers — which is exactly the substitution the pin exists to close. An unpinned
upgraded entry is exposed on each connect until the flag settles.
The conclusion is unchanged and now rests on the accurate claim: that exposure
is the status quo ante, identical to what the entry already had under 3.0.1, and
refusing to start does not remove it — it removes the integration, and an
integration that will not start protects nothing. Retrying converts a
pre-existing, bounded exposure into a closed one at the first successful setup.
Refusing converts it into a guaranteed outage with the credential no safer.
This matters because of why the docstring exists at all: to stop a later reader
"fixing" the asymmetry between a new entry, which cannot be created unpinned,
and an upgraded one, which may start that way. Resting it on "nothing crosses
the wire" would have failed precisely against the reader who noticed the broker
password does — they would have concluded the reasoning was wrong and changed
the behaviour, which is the outcome it was written to prevent.
Same correction in the README, which repeated the phrasing.

Subject: [PATCH 127/345] fix(control): report a refused panel command where
the user made it
The library refuses a circuit relay or priority command for a circuit the
panel declares non-settable, raising SpanPanelServerError instead of
returning an outcome. Three things followed from that.
switch.py had no handling for it at all, so a refused relay command
propagated past the outcome check as a traceback and left the toggle
springing back with no explanation. It now raises a translated error,
after the publish and never before it, so the switch is never left
showing a position the relay did not take.
select.py's message named panel firmware as the cause. That was already
a guess -- SpanMqttClient raises this exception from exactly one place,
its refusal path -- and it is now wrong for a user whose circuit is
simply commissioned non-settable. All three messages state the
mechanism, which does not change, and carry the library's own reason
verbatim rather than diagnosing a cause the exception does not name.
select.py and button.py filed persistent notifications with hardcoded
English text. They raise HomeAssistantError instead, as number.py
already did, through the three translation keys that were already in
strings.json and unused: a refusal published nothing, so there is
nothing to correct later and nobody to tell but the caller, and a
notification keyed on the circuit outlived the failure.

Subject: [PATCH 128/345] fix(control): raise a command that was never handed
to the broker
A FAILED outcome is the one state the library makes a promise about --
never handed to paho, and refused rather than queued precisely so
nothing fires minutes later against a panel nobody is watching. That
promise was written to the log and nowhere else on the relay switch, and
the other three controls discarded the outcome entirely without ever
checking it.
All four now raise a translated error, worded apart from a refusal
because it is a different fact: a refusal never resolved an address,
this resolved one and never handed it over. The library's own detail is
carried through as the reason, the way a refusal's message already is.
ACCEPTED and UNCONFIRMED stay non-failures and still take the optimistic
write, which is now pinned for both rather than for UNCONFIRMED alone,
and the switch's write stays last so neither raise can leave it showing
a position the relay never took.
Also documents why settability is read at setup and deliberately not
re-read: permanent entity IDs are not the obstacle, since a reload
restores them from the registry -- the obstacle is a $settable the
publisher warns can be stale.

- **A breaker your panel refuses to operate now says so.** The switch had no handling for a refused relay command at all, so the failure surfaced as a traceback
in the log and a toggle that quietly sprang back. It now reports the panel's own reason where you pressed it, and the switch stays where the relay actually
is.
+- **A control command that never reached your panel now says so.** A relay, priority, GFE override or charge-limit command that the transport could not hand
+ over — the broker was disconnected, so it was refused rather than queued — was written to the log and nowhere else. It is reported where you issued it, and
+ says plainly that nothing was queued and nothing will happen later.
- **A refused circuit priority no longer blames your firmware.** The old message said the panel's firmware did not support the operation, which stopped being
the only explanation once your panel could also declare an individual circuit's priority fixed. The priority select and the GFE override button now carry the
panel's reason instead of guessing at one, and report it as an error on the control you used rather than as a notification that sits in the sidebar until you

| **Reinstalling to change the entity ID style gives back the old entity IDs** | The naming style is chosen at install and cannot be changed from the options, so reinstalling looks like the way to switch. It is not: every entity returns with the entity ID it had before. | Home Assistant remembers a removed entity for **30 days**, keyed on its unique ID, and restores that record's entity ID — along with its name, area, labels and icon — as soon as an entity with the same unique ID appears again. This integration's unique IDs do not change with the naming style, so the remembered ID wins over the one the new style asks for. Either clear the leftover registry entries between removing and reinstalling, or wait out the 30 days and let Home Assistant discard them. A tool such as [ha-registry-clean](https://github.com/LegoTypes/ha-registry-clean) can do the clearing; it is a separate project, not part of this integration. Clearing also discards the names, areas and labels you had assigned. |
| **Setup fails after downgrading the integration** | After installing an older release, the SPAN Panel config entry fails to set up and Home Assistant reports an unsupported configuration version. | The release that stopped storing the panel passphrase migrated the config entry to version 7. Home Assistant refuses to load a config entry whose version is newer than the installed integration understands, and there is no automatic downgrade. Reinstall the newer release, or restore a backup taken before the upgrade. Removing and re-adding the integration also works and preserves entity IDs, but needs the panel passphrase or physical access to the door again. |
| **"SPAN Panel certificate authority changed" repair** | The integration has stopped connecting and a repair reports two fingerprints: the one it pinned and the one the panel now advertises. Entities are unavailable. | The panel is presenting a different certificate authority than the one you accepted at setup. Two things look identical from here and only you can tell them apart: a firmware upgrade or a factory reset rotates the authority legitimately, and so does a device on your network standing in for your panel. **If you know why it changed**, open the repair, compare the new fingerprint, and accept it — that re-pins and reconnects. **If nothing should have changed**, do not accept. Check what else is on the panel's network segment first. The integration will not reconnect on its own and will not re-pin on its own, deliberately: retrying would mean waiting to succeed against whatever is answering. |
+| **A circuit re-commissioned in the SPAN App has the wrong controls** | A circuit whose configuration changed in the SPAN App — made controllable, locked, or set to never back up — still has the controls it had before. A newly controllable circuit has no Breaker switch. A newly locked one still shows its switch, and operating it reports that the command was refused. | Reload the integration (**Settings → Devices & Services → Span Panel → ⋮ → Reload**). Which control entities exist is decided when the integration starts, from what the panel declares about each circuit at that moment; a change made afterwards is picked up at the next reload or restart. Reloading is safe — entity IDs, history, names and areas are preserved, because they are keyed on identifiers that do not change. Until you reload, a control the panel no longer accepts is refused rather than published: the command is not queued and the breaker does not move. |
| **A control reports `unconfirmed`** | The logbook or the `span_panel_control_command` event says a command was `unconfirmed`. Nothing appears broken. | **This is not an error.** It means the panel took the command and did not report a change within the deadline, and the most common reason by far is that there was no change to report — the relay was already open, the priority was already that value. It is also indistinguishable from a silent rejection by the panel, because SPAN's firmware sends no reason code; the integration reports what it observed rather than guessing. The two outcomes that do mean something went wrong are `failed`, which means the command was never sent, and `refused:…`, which means this integration refused it and names why. |

@@ -274,6 +274,36 @@ This closes the question of whether to go verbatim everywhere. The migration mec
`entity_id`s — `sensor.span_panel_kitchen_instantPowerW`, breaking every user reference — or a decoupling of the two, which throws away the consistency the
helper exists to provide. Closing the mapping gets the whole benefit for none of that.
+## Settability is read at setup, and deliberately not re-read
+
+Which curated control entities exist is decided once, in each platform's `async_setup_entry`, from what the panel declares about each circuit at that moment.
+`switch` gates on `is_user_controllable`; `select` gates on that and on `is_never_backup`, which is a separate commissioning flag — a never-backup circuit has a
+working relay and a priority the panel pins.
+
+SPAN documents that re-commissioning a circuit in place cycles that child device's `$state` and republishes its `$description` with a new `$settable`. So a
+circuit's settability can change while the integration is running, in either direction, and the setup-time gate cannot see it:
+
+- **A circuit that stops being controllable keeps its entity.** The entity outlives its own controllability and every write it attempts now fails.
+- **A circuit that becomes controllable gets no entity.** Nothing is watching it, because no entity exists to watch, so this direction cannot be noticed from an
+ entity at all.
+
+Both are safe, and the first is now well behaved. `span-panel-api` refuses a circuit relay or priority command for a circuit the panel declares non-settable,
+raising rather than publishing, and each control reports that refusal as a translated error on the control the user touched. Nothing is silently published and
+nothing is silently swallowed. The remedy for both directions is a reload.
+
+**Nothing re-evaluates settability at runtime, and the reason is not the one to expect.** Permanent entity IDs are not the obstacle: the entity registry maps
+`unique_id` to `entity_id`, so a reload gives every entity back the ID it had, both platforms already leave the registry entries of controls they do not create
+in place, and `coordinator.request_reload()` is already used when a circuit is renamed. The mechanism is available and precedented.
+
+The obstacle is the signal. SPAN reports a firmware defect in which the `$settable` re-toggle on the runtime re-commissioning path is skipped until the service
+restarts — which is why the library refuses when _either_ the declaration or the `relay-controllable` value says no. Driving an entry-wide reload off a flag the
+publisher warns can be stale would tear down every entity in the entry, and with them the grace-period, energy-dip and current-monitor state, on a value that
+may not be true yet. An entity that exists and cleanly explains why it cannot act is a better answer than one that vanishes and reappears.
+
+**If this is ever built, build it as a Repair rather than as a reload.** `schema_repairs` is the module for something re-derived from live state on every
+refresh: raise a Repair naming the circuit that changed, touch no entity, and let the user choose when to reload. Waiting is cheap, and worth doing until a
+panel is actually observed changing a circuit's settability in the field — so far that behaviour is documented by SPAN rather than seen here.

Subject: [PATCH 129/345] test(fixtures): vendor the schema-1 capture, with a
version guard
The parent/child capture is test data. Reading it by import made this
suite depend on a runtime wheel continuing to ship files nothing at
runtime reads, and put 56 KB of them on every user's disk.
The objection to a copy was that it goes stale in silence. That needs
the version claim, not the file: `schema_one_tree.source` records the
release the copy came from, and `importlib.metadata` reports the release
installed. When the pin moves and nobody refreshes the capture,
`test_fixture_provenance.py` fails and names the refresh -- no checkout,
no network call, no second copy to compare against.
The recorded version sits beside the payload rather than inside it
because a refresh is a byte-for-byte copy: a key added to the JSON would
be overwritten by the next one. It is written as a pinned requirement so
it names the distribution as well as the version, in the same vocabulary
as the manifest requirement it has to agree with.
The guard is one test rather than a check in the loader. Stale
provenance is a maintenance fact, not a broken payload -- a loader-level
assertion would turn one actionable failure into several hundred
identical ones.
`tests/fixtures/README.md` documented this arrangement all along,
including the file name; it is true again, and its derived-variant
section now describes the in-memory derivation that replaced the
committed variants.

# Adapter fixtures
Real schema-adapter inputs, used by the field-path conformance tests via `tests/adapter_fixtures.py`. They are **committed rather than generated** so the test
-suite has no cross-repo dependency and CI needs no checkout of the library. The cost of that choice is that they go stale silently — hence this file.
+suite has no cross-repo dependency and CI needs no checkout of the library — and so no runtime wheel has to keep shipping test data for this repository's
+benefit. The cost of a copy is that it can go stale, which for `schema_one_tree.json` is answered by the version guard below.
## Provenance
Both are byte-identical copies from the `span-panel-api` repository:
-| File here | Source in `span-panel-api` |
-| ------------------------ | --------------------------------------------------------------------- |
-| `schema_zero_types.json` | `tests/fixtures/v2/homie_schema.json` |
-| `schema_one_tree.json` | `packages/schema-1/src/.../reference_payloads/parent_child_tree.json` |
+| File here | Source in `span-panel-api` | Version guard |
+| ------------------------ | ------------------------------------------------- | ------------------------ |
+| `schema_zero_types.json` | `tests/fixtures/v2/homie_schema.json` | none |
+| `schema_one_tree.json` | `tests/reference_payloads/parent_child_tree.json` | `schema_one_tree.source` |
Refresh by copying them again, and keep `schema_one_tree.json` byte-identical to its source: the library pins what that capture leaves unvalued against
panelbench's own baseline (`tests/test_reference_tree_values.py` there), so a copy that has drifted puts these tests on a wire no producer sends.
+Through the 1.1.0 release the parent/child capture also shipped as package data, at `span_panel_api_schema_1/reference_payloads/parent_child_tree.json` inside
+the installed wheel, and this repository imported it from there. `span-panel-api#162` takes it back out of the wheels, so the repository path above is the one
+to copy from.
+
If a copy changes shape rather than content, the loader in `tests/adapter_fixtures.py` is what needs updating — note that `schema_one_tree.json` is a **dict
-keyed by device id**, whose `$description` value is a **JSON string**, not a parsed object.
+keyed by device id**, whose `$description` value is a **JSON string**, not a parsed object. `tests/test_fixture_provenance.py` pins that shape, so a capture
+that arrives pre-parsed fails there rather than somewhere far from the fixture.
-## Derived variants
+## The version guard
-Both are produced from `schema_one_tree.json` by dropping every device whose parsed `$description["type"]` contains a marker. Regenerate with:
+`schema_one_tree.source` records the release the capture was copied from, as a pinned requirement:
-```bash
-uv run python - << 'PY'
-import json, pathlib
+```text
+span-panel-api-schema-1==1.1.0
+```
-tree = json.loads(pathlib.Path("tests/fixtures/schema_one_tree.json").read_text())
+`tests/test_fixture_provenance.py` holds that against `importlib.metadata.version("span-panel-api-schema-1")` — the release actually installed. When the pin in
+`manifest.json` moves and nobody refreshes the capture, that test fails and names the refresh, so staleness is loud rather than silent. It needs no checkout of
+the library and no network call, which is why a copy is safe to keep here at all.
-def drop(marker: str, out_name: str) -> None:
- kept = {
- device_id: topics
- for device_id, topics in tree.items()
- if marker not in json.loads(topics.get("$description", "{}")).get("type", "")
- }
- pathlib.Path(f"tests/fixtures/{out_name}").write_text(json.dumps(kept, indent=2) + "\n")
- print(f"{out_name}: {len(tree)} -> {len(kept)} devices")
+It is a separate file rather than a key inside the payload because a refresh is a byte-for-byte copy: anything added to the JSON would be overwritten by the
+next one. It names the distribution as well as the version because this repository pins three of them.
-drop(".bess", "schema_one_tree_batteryless.json")
-drop(".pv", "schema_one_tree_no_pv.json")
-PY
-```
+To refresh, in one commit:
+
+1. Copy `tests/reference_payloads/parent_child_tree.json` from `span-panel-api` over `schema_one_tree.json`, with no reformatting.
+2. Set the version in `schema_one_tree.source` to the release it came from.
+
+The guard only sees the version claim, not the bytes. A capture edited in place under an unchanged version is invisible to it — refresh from a release, never
+from a working tree that is ahead of one.
+
+## Derived variants
-Each must remove **exactly one** device (13 -> 12) and must retain the panel and both lugs devices. A variant that removed more would make the conformance tests
-pass for the wrong reason. Note `bess-mid` is typed `energy.ebus.device.mid` and correctly survives the `.bess` filter.
+The batteryless and PV-less trees are **derived in memory**, not committed: `adapter_fixtures.schema_one_tree(without="bess")` and `without="pv"` return the
+capture with that one device dropped. They were separate files once; deriving them means they cannot drift from the base, since the only difference either ever
+had was the one missing device. Each drops exactly one device (13 -> 12) and retains the panel and both lugs devices — a variant that removed more would make
+the conformance tests pass for the wrong reason. Note `bess-mid` is typed `energy.ebus.device.mid` and is not the BESS.
## Why these exist
-`schema_one_tree_batteryless.json` proves a panel with no BESS produces **no** `battery.*` entries — hardware absence, not degradation.
-`schema_one_tree_no_pv.json` proves the same for a panel that has power-flows telemetry but no PV device, which is the case telemetry-based capability detection
-gets wrong.
+The batteryless tree proves a panel with no BESS produces **no** `battery.*` entries — hardware absence, not degradation. The PV-less tree proves the same for a
+panel that has power-flows telemetry but no PV device, which is the case telemetry-based capability detection gets wrong.

Subject: [PATCH 130/345] test(fixtures): compare the vendored capture to its
source, not just to a version string
The existing provenance guard holds `schema_one_tree.source` against
`importlib.metadata.version("span-panel-api-schema-1")`. That catches a copy
that was never refreshed after a pin moved. It cannot catch one that was
refreshed wrongly -- reformatted, hand-edited, or taken from a working tree
ahead of the release it names -- because all three leave the version claim
correct and change only the bytes.
So compare the bytes. `SPAN_PANEL_API_DIR`, which already exists in
`.env.example` for editable installs, now also names the checkout the vendored
capture is compared against, byte for byte with no reformatting tolerance. The
comparison first confirms the checkout is on the release the capture claims:
written without that check it passed against a checkout sitting one release
behind, whose bytes happened to be the ones vendored here, which proves only
that the copy matches something.
Skips when no checkout is configured, or when the one configured is on another
release -- not every developer keeps a sibling checkout, and failing them for it
is what gets a check deleted rather than configured. Fails rather than skips
under `CI`, where the workflow clones one, following span-panel-api's stated
reason: a skip reads in a summary line exactly like a pass, and that is how a
stale vendored capture went unnoticed there for nine days. Both halves of that
asymmetry are themselves asserted, in both environments, for every state the
checkout resolver distinguishes.
`tests/conftest.py` reads `.env` directly, with no dotenv dependency, the same
way span-panel-api's does -- stripping the `export ` prefix this repository's
`.env.example` writes, and never overriding a value already exported.
CI clones SpanPanel/span-panel-api at a tag derived from
`schema_one_tree.source` rather than hardcoded: `span-panel-api-schema-1==1.1.0`
becomes `schema-1-v1.1.0`. A second copy of the pin could disagree with the
first, which would be a new instance of exactly the staleness this removes.
Both source locations are checked, newest first. span-panel-api#162 moves the
capture out of the schema_1 wheel into `tests/reference_payloads/`, and until no
pinnable release predates that merge the old path stays reachable.

+stale, which for `schema_one_tree.json` is answered by the two guards below.
## Provenance
Both are byte-identical copies from the `span-panel-api` repository:
-| File here | Source in `span-panel-api` | Version guard |
+| File here | Source in `$SPAN_PANEL_API_DIR` | Guarded by |
| ------------------------ | ------------------------------------------------- | ------------------------ |

| `schema_one_tree.json` | `tests/reference_payloads/parent_child_tree.json` | `schema_one_tree.source` |
Refresh by copying them again, and keep `schema_one_tree.json` byte-identical to its source: the library pins what that capture leaves unvalued against
panelbench's own baseline (`tests/test_reference_tree_values.py` there), so a copy that has drifted puts these tests on a wire no producer sends.
-Through the 1.1.0 release the parent/child capture also shipped as package data, at `span_panel_api_schema_1/reference_payloads/parent_child_tree.json` inside
-the installed wheel, and this repository imported it from there. `span-panel-api#162` takes it back out of the wheels, so the repository path above is the one
-to copy from.
+Through the 1.1.0 release the parent/child capture also shipped as package data, at `packages/schema-1/src/span_panel_api_schema_1/reference_payloads/` in the
+repository and inside the installed wheel, and this repository imported it from there. `span-panel-api#162` takes it back out of the wheels and moves it to
+`tests/reference_payloads/`, so the path in the table above is the one to copy from. The byte comparison below checks both locations, newest first, so it works
+against a checkout on either side of that merge; the older path can be dropped once no release this repository can pin still predates it.
If a copy changes shape rather than content, the loader in `tests/adapter_fixtures.py` is what needs updating — note that `schema_one_tree.json` is a **dict
keyed by device id**, whose `$description` value is a **JSON string**, not a parsed object. `tests/test_fixture_provenance.py` pins that shape, so a capture
that arrives pre-parsed fails there rather than somewhere far from the fixture.

`tests/test_fixture_provenance.py` holds that against `importlib.metadata.version("span-panel-api-schema-1")` — the release actually installed. When the pin in

+the library and no network call, which is why it runs everywhere and why a copy is safe to keep here at all.
It is a separate file rather than a key inside the payload because a refresh is a byte-for-byte copy: anything added to the JSON would be overwritten by the
next one. It names the distribution as well as the version because this repository pins three of them.
-To refresh, in one commit:
+What it cannot see is the bytes. A capture edited in place, reindented on the way in, or copied from a working tree that is ahead of the release it names
+satisfies this guard completely — the claim is a string, and the string is correct.
+
+### The byte comparison
+
+`test_the_vendored_capture_is_byte_identical_to_its_source` closes exactly that hole. It reads `SPAN_PANEL_API_DIR` (see `.env.example`), confirms the checkout
+is on the release `schema_one_tree.source` names, and compares the vendored copy against the capture there byte for byte, with no reformatting tolerance.
+
+The release check is not decoration. Written without it, the comparison passed against a checkout sitting one release behind the recorded one, whose bytes
+happened to be the ones vendored here — proving only that the copy matched _something_, and "something" includes the working tree it was mistakenly taken from.
+
+**A skip here is not a pass.** Without a checkout, or with one on another release, the comparison skips: not every developer keeps a sibling checkout, and
+failing them for it is what gets a check deleted rather than configured. Under `CI` it fails instead, because the workflow clones `span-panel-api` at the
+release the pin names, so an unset or misplaced path there means the wiring has come undone rather than that the check is unavailable. `span-panel-api` paid for
+this asymmetry and states the reason plainly in its `DEVELOPMENT.md`, under "A skip here is not a pass": _"A skip reads in a summary line exactly like a pass,
+and that is how a stale vendored capture went unnoticed for nine days."_ Do not make the skip unconditional.
+
+CI derives the tag from `schema_one_tree.source` rather than hardcoding it — `span-panel-api-schema-1==1.1.0` becomes `schema-1-v1.1.0` — so there is no second
+copy of the pin that could disagree with the first.
+
+### Refreshing
+
+In one commit:
-1. Copy `tests/reference_payloads/parent_child_tree.json` from `span-panel-api` over `schema_one_tree.json`, with no reformatting.
+1. Copy `tests/reference_payloads/parent_child_tree.json` from `$SPAN_PANEL_API_DIR` over `schema_one_tree.json`, with no reformatting.
2. Set the version in `schema_one_tree.source` to the release it came from.
-The guard only sees the version claim, not the bytes. A capture edited in place under an unchanged version is invisible to it — refresh from a release, never

+That is half the problem. A version claim catches a copy that was never
+refreshed; it cannot catch one that was refreshed *wrongly* -- reformatted,
+hand-edited, or taken from a working tree ahead of the release it names -- because
+those leave the claim intact and change only the bytes. So the second guard here
+compares the bytes, against the capture in a `span-panel-api` checkout named by

+and therefore skips when no checkout is configured -- but **fails** rather than
+skips under `CI`, where the workflow clones one. The library states the reason
+plainly, having paid for it: "A skip reads in a summary line exactly like a pass,
+and that is how a stale vendored capture went unnoticed for nine days"
+(`span-panel-api`, DEVELOPMENT.md, "A skip here is not a pass"). Anyone tempted to
+make the skip unconditional should read that first.

Subject: [PATCH 131/345] build(fixtures): stop the file-rewriting hooks from
touching vendored captures
The byte comparison added in the previous commit justified itself before it ever
ran in CI: pointed at a checkout on the release `schema_one_tree.source` names,
it fails, and the diagnosis it prints is right.
The cause is not Prettier. Nothing here runs Prettier over JSON --
`scripts/fix-markdown.sh` passes only `*.md` globs and `prek.toml` has no
Prettier hook -- and `.prettierrc` sets `tabWidth: 2` while the vendored capture
carries 1-space indentation, so it could not have produced these bytes in any
case. The capture is byte-identical to the `schema-1-v1.0.0` release artifact,
1-space indentation included, and its blob has not changed across any commit that
contained it. What is wrong is the claim, not the copy: `schema_one_tree.source`
records 1.1.0, and upstream re-captured and reformatted the payload between the
two releases.
The hazard is real, though, and lives in different hooks. `trailing-whitespace`,
`end-of-file-fixer` and `mixed-line-ending` rewrite files and cover `tests/`.
They have left the captures alone only because both happen to be
newline-terminated with LF endings and no trailing whitespace. Strip the final
newline from `schema_one_tree.json` and `end-of-file-fixer` reports `Fixing
tests/fixtures/schema_one_tree.json`; the first capture vendored without one
would have been silently rewritten on commit, and the guard would then have
failed against a source the copy genuinely matched when it was made. A vendored
byte-identical fixture and an unconditional formatter cannot both exist, and it
is the formatter that yields: the bytes are the artifact.
So exclude `tests/fixtures/schema_*.json` from those three hooks, and from
Prettier as a precaution against a JSON glob being added later. Scoped to
`schema_*.json` rather than the directory because only the adapter captures have
this property -- the README is prose we own, the migration YAMLs are
hand-written, and `unread_declarations_baseline.json` is a hand-maintained
inventory of one-line explanations. `schema_*` is the vocabulary
`tests/adapter_fixtures.py` already uses, so the next capture vendored is covered
without anyone remembering to widen the rule. The read-only hooks keep covering
these files; `check-json` especially should.
`schema_zero_types.json` was checked for the same drift and has none: it is
byte-identical to `homie_schema.json` at `schema-1-v1.0.0`, `v3.0.1`, `main` and
the post-#162 location. Its documented source path was wrong -- there is no
`tests/fixtures/v2/homie_schema.json` -- and both payloads' real paths, before
and after #162, are now recorded. It gets no byte guard: it comes from the
bootstrap distribution, which is released on its own tag line, and CI clones the
library once at one revision, so a comparison against the schema-1 tag would be
against an arbitrary bootstrap revision rather than a release. The README records
that gap rather than leaving it to be rediscovered.

+`tests/adapter_fixtures.py` already uses for adapter captures, so the next one vendored is covered without anyone remembering to widen the rule.
+
+The read-only hooks still cover these files, `check-json` in particular. A capture that does not parse is worth hearing about wherever it came from.
+
+## Why the flat capture has no byte guard
+
+`schema_zero_types.json` is vendored on the same terms as the tree but has no `.source` file and no byte comparison, and that is a deliberate gap rather than an
+oversight.
+
+It comes from the **bootstrap** distribution, `span-panel-api`, which is released on its own tag line (`v3.1.0`), while the tree comes from
+`span-panel-api-schema-1` (`schema-1-v1.1.0`). CI clones the library once, at one revision. A checkout positioned at the schema-1 tag holds the bootstrap
+sources at whatever state they happened to be in at that commit, which is not the same thing as a bootstrap _release_ — so a byte comparison there would be
+against an arbitrary revision, which is exactly the "proves only that the copy matches something" failure the tree's release check exists to prevent.
+
+Guarding it properly means either a second checkout at the bootstrap tag or a second job, and neither is free. Against that: the payload has been byte-stable
+upstream across every revision checked. The gap is recorded here so the next person weighs it rather than rediscovering it.

Subject: [PATCH 132/345] fix(fixtures): re-vendor the schema-1 capture, which
recorded a producer defect
The byte comparison added two commits ago justified itself the first time it ran
against a real checkout, and it caught a class of error nothing else in either
repository could see.
`tests/fixtures/schema_one_tree.json` was vendored from a stale sibling checkout.
`[tool.uv.sources]` pointed at a `span-panel-api` worktree that predated
span-panel-api#161, so `span_panel_api_schema_1.reference_payloads` resolved
there and the copy inherited a capture that still recorded the emitter's
`$settable` defect on a locked relay -- circuit `573066aa` advertising
`settable: true` on a relay the specification declares locked -- together with
`load-shed/priority` values of `UNKNOWN` that no producer publishes. This branch
has been testing its locked-circuit and priority-settability work against exactly
that defect.
The copy itself was faithful: byte-identical to the `schema-1-v1.0.0` release
artifact, and `schema_one_tree.source` claimed 1.1.0. Both halves looked right in
isolation. The version guard compared a string to a string and passed; the
conformance tests passed because they were asserting against the capture. Only
holding the bytes against the release the claim names showed the mismatch.
So: repoint the path overrides at the checkout that tracks `main`, and re-vendor
byte for byte from it. A path override redirects what every import in the suite
resolves to, and one left aimed at a stale checkout silently tests against a
producer that no longer exists.
Seven tests moved with the capture, none of them wrong to assert on the fixture:
`test_bess_telemetry.py` (3) carried the pre-#39 emitter frame, which its own
docstring named and told the next person to revisit on refresh. `power-flows` 0.3
defines a node balance -- every term positive when power flows into the thing it
names -- so the four terms sum to zero rather than three summing to the fourth,
`pv` is negative while producing, and a charging battery publishes positive. The
identity is now asserted against zero, which makes it a statement about the frame
rather than about four numbers. `test_charging_reads_positive` becomes
`test_charging_reads_negative`: the wire is charge-positive and each path negates
once, so both battery sensors are discharge-positive. The library pins the same
four values and the same relation on the same capture and says the earlier
fixture was the thing that was wrong. No production code changed --
`BATTERY_POWER_SENSOR` is the single negation it has been since 2.0.8, and what a
real panel displays depends on what that panel publishes.
`test_declared_but_unread.py` (2) and `test_schema_discovery.py` (2) followed
`circuit/connection/count` and `lugs/connection/count`, which the corrected
capture no longer declares; their baseline entries are dropped as the test's own
message instructs. The diagnostics assertion now addresses its row by path
instead of by position -- the ordering is pinned once already, and re-pinning it
there is why a dropped property failed that test with a diff about the wrong row.
`schema_zero_types.json` was checked for the same problem and has none: still
byte-identical to `homie_schema.json` on the updated `main`, which now includes
span-panel-api#165.

Subject: [PATCH 133/345] build(fixtures): refresh the vendored capture and its
provenance in one command
`tests/fixtures/schema_one_tree.json` and `tests/fixtures/schema_one_tree.source`
are one fact in two files, and until now two different actions updated them -- a
copy and an edit. Doing one and not the other was a single missed keystroke, and
that is precisely what happened: a capture whose claim about itself was wrong,
which every conformance test then passed against.
`scripts/refresh-vendored-capture.py` does both, so they cannot disagree.
It copies with `shutil.copyfile`, never a json round trip -- re-serialising
rewrites indentation, key order and float spelling, which is exactly what the
byte comparison rejects -- and reads the release out of the installed
distribution rather than taking it as an argument, so there is no third place for
the claim to be wrong. Both source locations are handled, newest first, with the
pre-#162 package-data path as the fallback.
It refuses rather than guesses, and the refusals are the point. No
`SPAN_PANEL_API_DIR`, a path that does not resolve, a directory that is not a
checkout, a checkout whose schema-1 release is not the one installed, a checkout
with the file at neither location -- and a checkout that is not standing on the
release's tag.
That last check is what makes this a safeguard rather than a convenience, and it
was added after finding the obvious version comparison insufficient: the stale
worktree the bad capture came from *declared* 1.1.0 while sitting on unreleased
work behind `main`, so the declaration and the pin agreed while the bytes were a
release old. A version in a working tree is intent; a tag is a fact, and only a
tag can be checked. Pointed at that worktree the script now stops.
Copying from unreleased work stays possible behind `--allow-unreleased`, because
it is occasionally correct -- the current copy is that case, taken from `main`
because schema-1-v1.1.0 is not cut. It is a flag rather than a warning
deliberately: this repository has already established that a message which stops
nothing reads exactly like success.
`SCHEMA_ONE_SOURCE_PATHS` and its companions move to `tests/adapter_fixtures.py`,
which already owns the vendored capture's vocabulary, so the script and
`test_fixture_provenance.py` read one list. A second copy is how the #162
fallback would silently outlive the merge in one place and not the other. The
`.env` reader is duplicated rather than shared, because `conftest.py` has to stay
free of heavy imports at collection time; it is twelve stable lines and a
divergence is harmless.
Documented in `tests/fixtures/README.md` and `developer.md`: the one command, the
manual steps it performs for anyone without a checkout to hand, and which of the
two guards tells you to run it -- the version claim catches a pin that moved
while the copy stayed put, the byte comparison catches a copy refreshed wrongly.
Both docs also record why the capture is **not** copied at test time, because
someone will propose it. It would put back the cross-repo dependency vendoring
removed, and it would make the byte comparison vacuous: a copy compared against
what it was just copied from can only ever pass. Committed bytes that are allowed
to disagree with their source are the whole mechanism -- that freedom is what let
the comparison find a capture vendored through a stale path override.

+## The vendored adapter captures
+
+`tests/fixtures/schema_one_tree.json` and `tests/fixtures/schema_zero_types.json` are byte copies of payloads that live in `span-panel-api`. Committing them is
+what keeps this suite free of a cross-repo dependency: the tests run with no sibling checkout, and no runtime wheel has to keep shipping test data.
+
+### Refreshing the parent/child capture
+
+```bash
+# SPAN_PANEL_API_DIR names the checkout; see .env.example
+uv run python scripts/refresh-vendored-capture.py
+```
+
+The script copies the capture byte for byte and writes the release it came from into `tests/fixtures/schema_one_tree.source`, in one action. **That is the
+reason it exists.** Those two facts — the bytes, and the claim about which release they are — were previously updated by two different actions, so doing one and
+not the other was a single missed keystroke; doing both from one command makes them incapable of disagreeing.
+
+It refuses more than it accepts, deliberately. No `SPAN_PANEL_API_DIR`, a path that does not resolve, a directory that is not a checkout, a checkout whose
+schema-1 release is not the one installed, a checkout that has the file at neither known location, or a checkout that is not standing on the release's tag — all
+of these stop before anything is written. The last one matters most: the refresh that went wrong copied from a worktree that _declared_ the installed release
+while sitting on unreleased work behind `main`, so the declaration and the pin agreed while the bytes were a release old. A version in a working tree is intent;
+a tag is a fact. Copying from unreleased work is still possible with `--allow-unreleased`, because it is occasionally correct — it is how the capture was
+corrected while the fix was only on `main` — but it has to be said out loud rather than warned about and ignored.
+
+Commit both files together. They are one fact in two files.
+
+### Which guard tells you to run it
+
+| Guard | Compares | Catches | Needs a checkout |
+| ----------------------------------------------------------- | ----------------------------------------------------------- | ------------------------------------------------------------------------------------ | ---------------- |
+| `test_the_vendored_capture_matches_the_installed_adapter` | `schema_one_tree.source` against the installed distribution | a pin that moved while the copy stayed put | no |
+| `test_the_vendored_capture_is_byte_identical_to_its_source` | the capture against the copy in that release | a copy refreshed **wrongly** — reformatted, edited, or taken from the wrong checkout | yes |
+
+The first fails everywhere, including CI, the moment `manifest.json` moves and nobody refreshes. The second needs `SPAN_PANEL_API_DIR`, so it **skips** locally
+when no checkout is configured or the configured one is on another release, and **fails** under `CI`, where the workflow clones `span-panel-api` at the release
+the pin names. That asymmetry is deliberate and should not be "fixed": `span-panel-api` paid for it and records the reason in its `DEVELOPMENT.md`, under "A
+skip here is not a pass" — _"A skip reads in a summary line exactly like a pass, and that is how a stale vendored capture went unnoticed for nine days."_
+
+Either failure names the refresh. Run the script.
+
+### Why the capture is not copied at test time
+
+Someone will eventually propose having the suite copy the fixture from `SPAN_PANEL_API_DIR` on every run, so it can never be stale. It would undo both things
+vendoring bought.
+
+It puts the cross-repo dependency back — every test run needing a `span-panel-api` checkout, which is exactly what committing the bytes removed. And it makes
+the byte comparison vacuous: a copy compared against the thing it was just copied from can only ever pass. **Committed bytes that are allowed to disagree with
+their source are the whole mechanism.** That freedom to disagree is what let the comparison find a capture vendored from a stale path override, which nothing
+else in either repository could see. A fixture that silently re-syncs itself cannot report anything.
+
## Knowing what the panel publishes that nothing reads
The panel declares more than this integration surfaces, and the gap is tracked mechanically rather than by memory.

+"""Refresh the vendored schema-1 capture and the release it records, in one action.
+
+`tests/fixtures/schema_one_tree.json` is a byte copy of a payload that lives in
+`span-panel-api`, and `tests/fixtures/schema_one_tree.source` records which
+release it was copied from. Two files, two facts, and **that is the whole reason
+this script exists**: until now they were updated by two different actions -- a
+copy and an edit -- so doing one and not the other was a single missed keystroke,
+and the result was a capture whose claim about itself was wrong. Performing both
+from one command makes them incapable of disagreeing, which is a stronger
+guarantee than any amount of care with a two-step README.
+
+It is not hypothetical. The capture was once refreshed from a checkout that sat
+behind the recorded release, producing a copy that was faithful to *a* release
+and mislabelled as another; it recorded a producer defect that upstream had
+already fixed, and every conformance test kept passing against it. So this script
+refuses to copy from a checkout whose schema-1 release is not the one installed,
+and refuses again unless that checkout is standing on the release's *tag* --
+because the stale worktree declared the right version while sitting on the wrong
+commit, and only a tag can be checked. Copying from unreleased work is still
+possible, with `--allow-unreleased`, because it is occasionally correct; it just
+has to be said out loud. Making the wrong refresh hard is more of the point than
+making the right one convenient.
+
+**The capture is deliberately not copied at test time.** Doing that would undo
+both things vendoring bought. It would put the cross-repo dependency back --
+every test run needing a `span-panel-api` checkout, which is exactly what

+stale checkout. A refresh is a deliberate act, taken here and reviewed in a diff.
+
+Usage, from the repository root:
+
+ uv run python scripts/refresh-vendored-capture.py
+
+`SPAN_PANEL_API_DIR` names the checkout; see `.env.example`. A correct run when
+nothing has moved upstream is a no-op and says so.

### Refreshing
-In one commit:
+Either guard failing names the refresh, and the refresh is one command:
-1. Copy `tests/reference_payloads/parent_child_tree.json` from `$SPAN_PANEL_API_DIR` over `schema_one_tree.json`, with no reformatting.
-2. Set the version in `schema_one_tree.source` to the release it came from.
+```bash
+# SPAN_PANEL_API_DIR names the checkout; see .env.example
+uv run python scripts/refresh-vendored-capture.py
+```
+
+Commit both files it touches together — they are one fact in two files.
+
+What it does, for anyone reading this without the checkout to hand:
+
+1. Copies `tests/reference_payloads/parent_child_tree.json` from `$SPAN_PANEL_API_DIR` over `schema_one_tree.json`, byte for byte — `shutil.copyfile`, never a
+ `json.load`/`json.dump` round trip, which would rewrite indentation, key order and float spelling and produce exactly what the byte comparison rejects. It
+ checks the pre-#162 package-data path as a fallback, so it works against a checkout on either side of that merge.
+2. Writes `schema_one_tree.source` from the **installed** distribution's version, rather than from anything typed in.
+
+**Doing both from one command is the point, not the convenience.** The bytes and the recorded release used to be updated by two different actions, so doing one
+and not the other was a single missed keystroke — and the result was a capture whose claim about itself was wrong, which every conformance test then passed
+against. One command cannot do half of it.
+
+It refuses rather than guesses: no `SPAN_PANEL_API_DIR`, a path that does not resolve, a directory that is not a checkout, a checkout whose schema-1 release is
+not the one installed, a checkout with the file at neither location, or a checkout that is not standing on the release's tag. That last one is the one that
+matters: the refresh that went wrong copied from a worktree that _declared_ the installed release while sitting on unreleased work behind `main`, so the
+declaration and the pin agreed while the bytes were a release old. A version in a working tree is intent; a tag is a fact, and only a tag can be checked.
+
+Copying from unreleased work is still possible with `--allow-unreleased`, because it is occasionally correct — the current copy is exactly that case, taken from
+`main` because `schema-1-v1.1.0` is not cut and the alternative was to keep shipping a capture that records a producer defect. It verifies against a `main`
+checkout today and will verify against the tag once 1.1.0 is released from these bytes; if `main` moves the capture again first, the guard says so, which is the
+whole point. What is never acceptable is a capture taken from a checkout _behind_ the recorded release — that is how this one went wrong.
+
+### Why the capture is not copied at test time
+
+Someone will eventually propose having the suite copy the fixture from `$SPAN_PANEL_API_DIR` on every run, so it can never be stale. It would undo both things
+vendoring bought.
-Copy from a checkout positioned on the release `schema_one_tree.source` names, and prefer a released tag. The current copy is an exception made knowingly: it
-comes from `main`, because `schema-1-v1.1.0` is not cut yet and the alternative was to keep shipping a capture that records a producer defect. It verifies
-against a `main` checkout today and will verify against the tag once 1.1.0 is released from these bytes; if `main` moves the capture again first, the guard says
-so, which is the whole point. What is never acceptable is a capture taken from a checkout that is _behind_ the recorded release — that is how this one went
-wrong.
+It puts the cross-repo dependency back — every test run needing a `span-panel-api` checkout, which is exactly what committing the bytes removed. And it makes
+the byte comparison vacuous: a copy compared against the thing it was just copied from can only ever pass. **Committed bytes that are allowed to disagree with
+their source are the whole mechanism.** That freedom to disagree is what let the comparison find a capture vendored from a stale path override, which nothing
+else in either repository could see. A fixture that silently re-syncs itself cannot report anything.

Subject: [PATCH 134/345] build: point the type-checker path at the library
checkout, not a worktree
`extraPaths` named `span-panel-api-security`, a scratch worktree created for the
security work and merged since. Two consequences, one of which was visible all
along: Pyright resolved `span_panel_api` through both that path and the
installed distribution, so every symbol crossing the boundary reported as two
incompatible types with the same name -- `models.V2HomieSchema` is not
assignable to `span_panel_api.models.V2HomieSchema`. mypy, which reads the
installed distribution alone, was clean throughout.
The second is that the path was about to break: the worktree is being removed
now that its branch is merged.
`[tool.uv.sources]` above already names the real checkout; this line was the
one left behind.

Subject: [PATCH 135/345] fix(sensors): a derived reading is unknown while its
inputs are
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
span-panel-api now reports a meter value the panel has not sent as None
rather than fabricating 0.0, because on a cumulative counter the two are
not interchangeable — a fabricated zero is indistinguishable from the
reset the dip compensator exists to absorb (SpanPanel/span#259).
The four derived value functions flattened that distinction straight back
out. Net energy, at circuit and panel level, was `(a or 0) - (b or 0)`, so
a circuit that had reported nothing answered a confident 0 Wh; those are
TOTAL, not TOTAL_INCREASING, so the cost is a false dip to zero in history
rather than corrupted statistics, but it is the same invented reading one
layer further out and past the point where anything downstream can tell.
Circuit power failed the other way: `-c.instant_power_w` raises TypeError
on None, caught upstream and logged as a value-function failure for every
PV circuit on every replay.
Both now compose through helpers that propagate None, which reaches
_process_raw_value and renders the sensor unknown. The panel pair were the
worst exposed: both lugs devices are told apart by one `direction`
property, so until it arrives neither role resolves and all four inputs
are absent together.
Test factories widen to float | None to match the snapshot model.

Subject: [PATCH 136/345] fix(dip): a compensation offset the next reading
disproves is retracted
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Dip compensation booked an offset the moment a counter read lower than it
had, on the evidence of one sample, and that write is irreversible: it
lands in long-term statistics, where undoing it is a manual adjustment per
affected hour. SpanPanel/span#259 is what a wrong sample costs there — a
transient zero booking a circuit's whole lifetime counter, every restart,
reaching 8.18 MWh on one circuit.
A firmware counter reset is permanent: the counter restarts low and counts
up from there. So a reading that drops and then returns was never a reset.
Compensation is still applied the moment the drop is seen, because the
sensor has to stay correct meanwhile, but the conclusion is held open:
retract raw >= baseline - 1.0 the counter came back
confirm dipped_raw < raw < baseline-1.0 it is counting from the lower base
hold raw == dipped_raw no evidence either way
Confirmation needs independent progress rather than a second low reading.
Snapshots dispatch on a debounce, so one replay can deliver the same
incomplete state twice; a rule satisfied by any low reading would be
satisfied by a second copy of the sample it exists to reject.
The notification moves from detection to confirmation. Firing on sight is
what made #259 so loud — a notification naming essentially every circuit
on the panel for an event that had not happened. A retracted dip now
produces none, because nothing happened.
The pending record persists, because a restart is exactly when one is most
likely to be outstanding: the reading that settles a dip is the one after
the reading that booked it, and HA can stop in between. Forgetting it was
provisional would make the restart itself the thing that makes a bad
offset permanent.
Two existing tests pinned the old behaviour and now state the new: a
counter that came back used to leave its offset behind for good, and the
coordinator was told on detection.
Cost: a genuine reset on a circuit drawing nothing stays unconfirmed until
it next moves. Only the notification waits; compensation applies
throughout.

Pure functions for detecting energy value dips (typically caused by panel firmware
resets) and computing the compensated value to maintain monotonic TOTAL_INCREASING

+"""A counter reset is permanent, so a dip the next reading disproves is retracted.
+
+Dip compensation books an offset the moment a counter reads lower than it did,
+and that write is irreversible: it lands in Home Assistant's long-term
+statistics. The evidence for it is one sample. `SpanPanel/span#259` is what that
+costs when the sample is wrong — a transient zero booked the whole lifetime
+counter as an offset on every restart, reaching megawatt-hours.
+
+The library no longer fabricates that particular zero (an unreported reading is
+`None`, which skips compensation entirely). This is the layer under it: whatever
+the source, a reading that drops and then comes back was never a reset, because
+a reset is permanent. So the offset is provisional until a later reading either
+disproves it — the counter returns to where it was — or corroborates it, by
+counting up from the lower base.
+
+**Corroboration needs independent progress, not merely a second low reading.**
+Confirming on any reading below the baseline would confirm on a second copy of
+the same bad sample, which is exactly the shape a replay produces: snapshots are
+dispatched on a debounce, so one burst can deliver the same incomplete state
+twice. That is the failure this rule exists to catch, so it must not be the
+failure that satisfies it.
+
+The cost is that a genuine reset on a circuit drawing nothing stays unconfirmed
+until it next moves. Compensation is applied throughout — only the notification
+waits — so the sensor reads correctly while the evidence is outstanding.

Subject: [PATCH 137/345] build: hold span-panel-api to the checkout, at commit
time and at run time
`3cbf02a` pointed `[tool.uv.sources]` and `[tool.pyright].extraPaths` at a
scratch worktree and committed it. It stood until `82a512f` -- several commits
and hours of other work -- and while it stood a test fixture was vendored
through that resolution from a checkout that still recorded a producer defect
the library had already fixed. Every version-based check passed, because the
stale worktree declared the same version number as the corrected code. Only a
byte comparison caught it.
A version string does not identify content. Only a filesystem location does.
Three layers, so the defect cannot repeat.
`tests/test_library_resolution.py` reads `span_panel_api.__file__` and compares
it against what `pyproject.toml` declares and what `manifest.json` pins --
neither written down here, both derived. The pinned version out of the declared
location passes. That location at another version fails everywhere: nothing
else can see it, because every copy of the pin agrees with the checkout's own
declaration. A deliberate editable override skips locally, naming the path and
version it found, and fails under `CI`, where the workflow deletes
`[tool.uv.sources]` and no legitimate override exists.
The fourth case is the dangerous one. A worktree on `PYTHONPATH` or `MYPYPATH`
has no distribution metadata, so `importlib.metadata` keeps describing the
installed distribution -- right name, right version, right location -- while
the code that runs comes from somewhere else. Every version check passes on
facts about a copy that is not running. Classified before the version is
compared, because in that state the comparison is not about the code under
test.
`developer.md` documents the alternative to editing a committed file: install
the worktree into the venv, `uv sync` to undo it. The root cause was that
working against unreleased library code required editing a shared file; it does
not any more.
`scripts/check-library-path.py` rejects a `pyproject.toml` whose span-panel-api
paths name anything but `../../span/span-panel-api`, and says how to redirect
the library without touching the file. Both blocks, not just the sources one:
they went wrong together and were corrected separately, `extraPaths` lagging by
several commits because nothing was watching it. An absent block passes -- CI
deletes it before installing and re-runs these hooks against what is left.
The skip-locally, fail-in-CI asymmetry and its reasoning are
`test_fixture_provenance.py`'s: a skip reads in a summary line exactly like a
pass.

```
+## Working against unreleased library code
+
+`pyproject.toml` installs `span-panel-api` and both adapters from `../../span/span-panel-api` as editable path dependencies. That is a committed, shared file:
+whatever it names is what every import in this suite resolves to, for everyone, on every machine.
+
+Sooner or later you need to test against library work that is not on `main` yet — an unmerged branch in a worktree beside the checkout. **Do not edit
+`pyproject.toml` to point at it.** Put the worktree in your virtual environment instead:
+
+```bash
+uv sync # canonical, from the committed file
+uv pip install -e ../../span/span-panel-api- # local override, this venv only
+uv sync # back to canonical
+```
+
+`uv sync` is the undo. It rebuilds the environment from `pyproject.toml` and `uv.lock`, which never mentioned the worktree, so the override disappears with no
+record of having been there. Nothing is committed at any point.
+
+### What the second install actually does
+
+The venv holds one `.pth` file per editable distribution — `_editable_impl_span_panel_api.pth`, `_editable_impl_span_panel_api_schema_0.pth`,
+`_editable_impl_span_panel_api_schema_1.pth` — each holding the `src` directory of the main checkout. `uv pip install -e ` **replaces** the one for
+the distribution it installs: same filename, rewritten to the worktree, with the `dist-info` (including `direct_url.json`, which is where the redirection is
+recorded as data) replaced alongside it. There is no stacking and no shadowing, so no ordering question — the old target is gone.
+
+It replaces only that distribution. `span-panel-api` and the two adapters are three separate distributions, and installing the bootstrap from a worktree leaves
+`span_panel_api_schema_0` and `span_panel_api_schema_1` resolving to the main checkout. If the branch under test changes an adapter, or moves
+`ADAPTER_CONTRACT_VERSION`, install all three:
+
+```bash
+uv pip install -e ../../span/span-panel-api- \
+ -e ../../span/span-panel-api-/packages/schema-0 \
+ -e ../../span/span-panel-api-/packages/schema-1
+```
+
+### What not to do: `PYTHONPATH` and `MYPYPATH`
+
+Prefixing a worktree onto `PYTHONPATH` or `MYPYPATH` looks like the same thing and is not. A worktree on the path has **no distribution metadata of its own**,
+so `importlib.metadata` goes on describing the installed distribution: the right name, the right version, the right location — all of it about a copy of the
+library that is not the one running. `span_panel_api.__file__` is in the worktree and every version-based check in this suite reads the installed distribution
+and passes.
+
+That is the worst available state, because it is the one where everything is green. The editable install moves the code and the metadata together, so they
+cannot disagree; the path prefix moves one and not the other.
+
+### The two guards
+
+| Guard | When | Catches |
+| ------------------------------------------- | ----------- | ---------------------------------------------------------------------------- |
+| `scripts/check-library-path.py` (prek hook) | commit time | a `span-panel-api` path in `pyproject.toml` naming anything but the checkout |
+| `tests/test_library_resolution.py` | every run | the library that actually resolved not being the one `manifest.json` pins |
+
+The hook is why editing `pyproject.toml` is not the route: it rejects the commit and names this section. The test reads `span_panel_api.__file__` rather than
+metadata, so it sees the `PYTHONPATH` case as well as a stale checkout. A deliberate editable override **skips** it locally, naming the path and version it
+found, and **fails** under `CI` — where `[tool.uv.sources]` is deleted before installing and no legitimate override exists. A version behind or ahead of the pin
+fails everywhere; that one is never intentional.
+
+### Why the version alone is not enough
+
+`3cbf02a` pointed both `[tool.uv.sources]` and `[tool.pyright].extraPaths` at a scratch worktree and committed it. It survived several commits and hours of
+other work. While it stood, a test fixture was vendored through that resolution and captured a producer defect the library had already fixed — and every
+version-based check passed, because the stale worktree declared the same version number as the corrected code. Only a byte comparison caught it.
+
+**A version string does not identify content. Only a filesystem location does.** That is what both guards check and why neither of them checks a version on its
+own.

+checker reads. Both are written as relative paths so they mean the same thing in
+the primary checkout and in every worktree beside it.
+
+Working against unreleased library code needs those paths aimed somewhere else
+for a while, and the obvious way to do that is to edit them. That is what
+happened in `3cbf02a`: both blocks were pointed at a scratch worktree and
+committed. It stood for several commits and a few hours of other people's work,
+and while it stood a test fixture was vendored through it from a checkout that
+still recorded a producer defect the library had already fixed. Every
+version-based check passed -- the stale worktree declared the same version number
+as the corrected code -- and only a byte comparison caught it. A version string
+does not identify content; only a filesystem location does.
+
+So the redirection does not belong in a committed file at all. It belongs in the
+virtual environment, where it affects one developer's next command and nothing
+else, and `developer.md` ("Working against unreleased library code") says how.
+This hook is what makes that the only route: it rejects a `pyproject.toml` whose
+`span-panel-api` paths name anything but the checkout.
+
+Absence is not a failure. CI deletes the whole `[tool.uv.sources]` block before
+installing, so it resolves from PyPI and re-runs these hooks against a file that
+no longer has one. A block that is not there declares nothing to be wrong about.

+"""The `span_panel_api` under test must be the one the pins name.
+
+Every other guard in this suite reads a version. `manifest.json` pins one,
+`scripts/sync-dependencies.py` holds the copies to it, `test_fixture_provenance.py`
+compares the vendored capture against it. All of that assumes the version string
+identifies the code, and it does not: a checkout sitting on unreleased work
+declares the same version as the release it is ahead of, and a scratch worktree
+declares the same version as the checkout it was branched from. A version is a
+claim; a filesystem location is a fact.
+
+That gap is not hypothetical here. `3cbf02a` pointed `[tool.uv.sources]` at a
+scratch worktree and committed it, so every import in the suite resolved through
+a checkout that had never received span-panel-api#161. A fixture was vendored
+through it while it stood, capturing an emitter defect that had already been
+fixed. Every version check in both repositories passed. Only a byte comparison
+saw it, and only because that comparison had a real second copy to look at.
+
+So this file checks the one thing no version can: **where the module actually came
+from**. It reads `span_panel_api.__file__`, not metadata, because those two can
+disagree -- see `Verdict.INCONSISTENT` -- and when they do it is metadata that is
+wrong.
+
+Nothing here writes down a version or a path. The pinned version is read from
+`manifest.json`, which is the only file whose pins reach a user, and the expected
+location is read from `[tool.uv.sources]` in `pyproject.toml`, which is what the
+environment is actually built from. A guard carrying its own copy of the fact it
+is guarding is the same duplicated-knowledge defect in miniature, and it fails
+the day somebody bumps the real one.
+
+Deliberate local overrides **skip** rather than fail, and only off CI. Testing
+against an unreleased library is a supported workflow -- `developer.md`, "Working
+against unreleased library code" -- and a guard that punishes the workflow it is
+protecting gets deleted. Under `CI` there is no such thing as a legitimate
+override: the workflow deletes `[tool.uv.sources]` and resolves from PyPI, so
+anything but the pinned distribution in the environment's own site-packages means
+the wiring has come undone. The asymmetry, and the reason a skip is not a pass,
+are `test_fixture_provenance.py`'s -- "A skip reads in a summary line exactly like

Subject: [PATCH 138/345] test(library-path): prove the gate against the
commits it exists for
The hook's failing cases were miniature pyproject.toml files written here. A
synthetic defect is written by somebody who already knows what the rule checks,
so it exercises the rule rather than the mistake -- a gate proven against a
made-up example is proven against the wrong thing.
Both failing cases are now byte copies of this repository's own pyproject.toml,
taken out of its history and held to it:
pyproject_both_blocks_redirected.toml 3cbf02a, both blocks on the
scratch worktree
pyproject_type_checker_path_left_behind.toml 82a512f^, sources corrected and
extraPaths not
The second is the interval between the two corrections, several commits during
which the repository looked fixed. It is the case a hook covering only
`[tool.uv.sources]` calls clean, and it asserts that the corrected half is *not*
reported -- so what fails there is the half that was genuinely still broken.
Each copy has a `.source` recording its commit, and a guard holding the bytes to
it, or the obvious way to make a failing case pass is to edit the fixture. That
guard skips when the object is unreachable, which this directory's other
provenance guard refuses to do. The difference is that a commit is
content-addressed: `3cbf02a:pyproject.toml` cannot become different bytes, so
the comparison can only ever report a copy that was wrong when it was vendored,
and it reports that wherever the history exists. A shallow clone has no object
to compare against, and asserting anyway would fail on the clone rather than on
the fixture.
Every case drives `scripts/check-library-path.py` as a subprocess, the way prek
invokes it -- never the module's functions, never the rule restated in the test.
`test_the_hook_prek_runs_is_the_one_tested` closes what that leaves open by
reading the entry back out of `prek.toml`: rename the script or the hook and
every other case here goes on passing against something prek no longer runs, and
an unregistered hook produces no output either. It reads the file as text
because `prek.toml` spreads each hook's inline table over several lines, which
is TOML 1.1 and `tomllib` rejects.
The two vendored copies join the adapter captures in being exempt from the
rewriting hooks, for the reason already recorded there: a formatter and a
byte-identical fixture cannot both be unconditional, and it is the formatter
that yields.

+decide where the library comes from at a scratch worktree and committed it, and

-and checks that it says so.
+clean tree.
+
+Two things this file is careful about, because getting either wrong would leave a
+gate that is only proven against itself.
+
+**It drives the real entry point.** Every case runs
+`scripts/check-library-path.py` as a subprocess and reads its exit status and
+output, exactly as prek invokes it -- never the module's functions, and never a
+reimplementation of the rule in the test. A test that reimplements the logic
+proves the test's copy of the logic. `test_the_hook_prek_runs_is_the_one_tested`
+closes the remaining gap by reading the entry out of `prek.toml`: a hook renamed
+there and not here would otherwise go unregistered while these tests kept passing.
+
+**The failing cases are the real files.** `tests/fixtures/pyproject_*.toml` are
+byte copies of `pyproject.toml` at the two commits where this actually went
+wrong, taken straight out of this repository's history and held to it by
+`test_the_vendored_copies_are_the_commits_they_name`. A gate proven against a
+made-up example is proven against the wrong thing: the synthetic version of a
+defect is written by someone who already knows what the rule checks, so it
+exercises the rule rather than the mistake. The two states nothing in history
+provides -- an absent `[tool.uv.sources]` block, an `extraPaths` naming only
+unrelated repositories -- are the only ones constructed here.
Lives here rather than beside the script in `tests/scripts/`, which `pytest.ini`
excludes with `norecursedirs`. A test that is never collected is the same failure

Subject: [PATCH 139/345] test(dip): an outage delays a dip's verdict rather
than deciding it
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Grace period and dip compensation share a stored record but not a
decision, and nothing pinned the boundary. While the panel is offline
`_update_native_value` hands off to the grace period and returns before any
dip processing, so an outage cannot book, confirm or retract anything.
That division is deliberate: grace period answers what a sensor should read
while the panel is unreachable, dip compensation answers what the counter
did, and an outage is evidence about the transport rather than about the
counter. The alternative matters — an outage landing between a dip and the
reading that would settle it could otherwise confirm a bad offset by
default, which is the same shape as forgetting the pending record across a
restart.
Covers the three parts: the pending record and offset survive the outage
untouched, grace holds the compensated value HA was already showing, and
the dip settles normally once the panel returns.

Subject: [PATCH 140/345] docs: state what dip compensation now does, and how
to check an old offset
Two corrections to the README, both consequences of the retraction rule.
The feature section said a persistent notification lists affected sensors
"when a dip is detected". That is no longer true and teaches the wrong
model: a dip is compensated on sight but not believed, so the notification
fires on corroboration a reading later, and a disproved dip produces none
at all. Someone watching a momentary dip pass with no notification would
reasonably conclude the feature had failed, when that silence is it
working.
The troubleshooting row offered dip compensation as the prevention for
energy dashboard spikes, which after #259 is half the story -- compensation
could manufacture them. It now also says how to check: an `energy_offset`
far larger than the sensor's own reading is compensation for a dip that
never happened, and toggling the option off discards it.
It says plainly what that cannot do. Offsets booked before 2.1.0 were never
corroborated, so the integration cannot tell a good one from a bad one
retrospectively -- which is why there is no repair flow offering to. And
clearing an offset fixes the future only; spikes already written into
long-term statistics still need Adjust sum.
Table rows reflow because the column padding is recomputed; the text change
is confined to the one cell. Both edits are `scripts/fix-markdown.sh`
output.

Caused by the panel reporting decreased values on otherwise`TOTAL_INCREASING` sensors. | **Prevention:** enable [Energy Dip Compensation](#energy-dip-compensation) in General Options (on by default for new installs). **Fix existing spikes:** in **Developer Tools → Statistics**, search for the affected sensor (e.g. `sensor.span_panel_main_meter_consumed_energy`) and use **Adjust sum** to correct the errant entry. The integration also notifies when a decrease in the main meter consumed sensor is detected. |
-| **High CPU usage** | Elevated CPU on low-power hardware (e.g. Raspberry Pi). The integration rebuilds a full panel snapshot from MQTT messages at a configurable interval (default 1 s). | Increase**Snapshot Update Interval** in **General Options**. 10–15 s is recommended for resource-constrained systems. Setting it to 0 disables debouncing and rebuilds on every MQTT message — not recommended. |
-| **Replaced sub-device shows the old serial number** | After replacing a SPAN sub-device (Drive / EVSE, BESS, PV inverter), the device entry in Home Assistant keeps showing the previous hardware's serial number. The integration keys entities off the panel-assigned node identity, which is intentionally stable across hardware swaps so long-term history (e.g. lifetime charging kWh for a Drive) is preserved. The device-registry serial number, however, does not auto-refresh. | In**Settings → Devices & Services → Span Panel**, open the affected sub-device and delete it, then reload the integration (or restart Home Assistant). The device re-registers with the new serial number. Entity IDs and their recorded history are preserved. |
-| **Door sensor unavailable** | The SPAN API returns UNKNOWN if the cabinet door has not been operated recently. This is a defect in the SPAN API. | The integration reports the sensor as unavailable until a proper value arrives. Opening or closing the door publishes the correct state. The door is classified as a tamper sensor (`Detected` / `Clear`) to differentiate it from a normal entry door. |
-| **No switch on a circuit** | A circuit has no switch entity exposed in Home Assistant. | The circuit is configured in the SPAN App as one of the "Always on Circuits". The API does not permit user control of those circuits, so no switch is created. |
-| **Reinstalling to change the entity ID style gives back the old entity IDs** | The naming style is chosen at install and cannot be changed from the options, so reinstalling looks like the way to switch. It is not: every entity returns with the entity ID it had before. | Home Assistant remembers a removed entity for **30 days**, keyed on its unique ID, and restores that record's entity ID — along with its name, area, labels and icon — as soon as an entity with the same unique ID appears again. This integration's unique IDs do not change with the naming style, so the remembered ID wins over the one the new style asks for. Either clear the leftover registry entries between removing and reinstalling, or wait out the 30 days and let Home Assistant discard them. A tool such as [ha-registry-clean](https://github.com/LegoTypes/ha-registry-clean) can do the clearing; it is a separate project, not part of this integration. Clearing also discards the names, areas and labels you had assigned. |
-| **Setup fails after downgrading the integration** | After installing an older release, the SPAN Panel config entry fails to set up and Home Assistant reports an unsupported configuration version. | The release that stopped storing the panel passphrase migrated the config entry to version 7. Home Assistant refuses to load a config entry whose version is newer than the installed integration understands, and there is no automatic downgrade. Reinstall the newer release, or restore a backup taken before the upgrade. Removing and re-adding the integration also works and preserves entity IDs, but needs the panel passphrase or physical access to the door again. |

Entities are unavailable. | The panel is presenting a different certificate authority than the one you accepted at setup. Two things look identical from here and only you can tell them apart: a firmware upgrade or a factory reset rotates the authority legitimately, and so does a device on your network standing in for your panel. **If you know why it changed**, open the repair, compare the new fingerprint, and accept it — that re-pins and reconnects. **If nothing should have changed**, do not accept. Check what else is on the panel's network segment first. The integration will not reconnect on its own and will not re-pin on its own, deliberately: retrying would mean waiting to succeed against whatever is answering. |
-| **A circuit re-commissioned in the SPAN App has the wrong controls** | A circuit whose configuration changed in the SPAN App — made controllable, locked, or set to never back up — still has the controls it had before. A newly controllable circuit has no Breaker switch. A newly locked one still shows its switch, and operating it reports that the command was refused. | Reload the integration (**Settings → Devices & Services → Span Panel → ⋮ → Reload**). Which control entities exist is decided when the integration starts, from what the panel declares about each circuit at that moment; a change made afterwards is picked up at the next reload or restart. Reloading is safe — entity IDs, history, names and areas are preserved, because they are keyed on identifiers that do not change. Until you reload, a control the panel no longer accepts is refused rather than published: the command is not queued and the breaker does not move. |
-| **A control reports `unconfirmed`** | The logbook or the `span_panel_control_command` event says a command was `unconfirmed`. Nothing appears broken. | **This is not an error.** It means the panel took the command and did not report a change within the deadline, and the most common reason by far is that there was no change to report — the relay was already open, the priority was already that value. It is also indistinguishable from a silent rejection by the panel, because SPAN's firmware sends no reason code; the integration reports what it observed rather than guessing. The two outcomes that do mean something went wrong are `failed`, which means the command was never sent, and `refused:…`, which means this integration refused it and names why. |

Subject: [PATCH 141/345] test(control): pin that disabling control keeps the
entity_ids it stops creating
`disabled` had to be a mode that stops *creating* controls rather than one that
removes them, because entity_id is permanent here. Nothing asserted that. The
existing test checks only that no entities are added, which both spellings
satisfy -- a mode that removed every registry entry on the way past would have
passed it unchanged.
Its docstring claimed the other half anyway: "No control entities, and no
registry entries removed either." A claim made in a docstring and checked
nowhere is worse than an absent test, because it reads as coverage to anyone
auditing by name -- which is how this gap was found. That sentence now says
what the test actually proves and points at the one below.
The new test registers an entry, customises its name and icon, runs setup under
`disabled`, and asserts the entry survives with its entity_id, its unique_id
mapping and its customisations intact. Customised rather than bare because the
cost of getting this wrong is not the identifier alone: a user's name, area and
icon travel with the registry entry and do not come back with a reissued id.
Verified by injecting the defect -- removing the switch entries on the disabled
path -- and confirming this fails, then restoring. A guard that has never been
seen to fire is not known to be a guard.

Subject: [PATCH 142/345] chore: 2.1.0b15
The first beta whose pins resolve. b14 named span-panel-api 3.1.0 and both
adapters at 1.1.0 while none of the three existed on PyPI, so the pins were
honest about what the code needed and unsatisfiable by anyone but a developer
with local path overrides -- deliberately, since the alternative was pins that
resolved to a library without the changes. All three published today, so CI can
now install what the manifest asks for.
What the beta carries beyond b14:
- The panel credential no longer travels or rests in clear. The passphrase is
not persisted, and the CA is fetched and confirmed before registration rather
than after, so the exchange that carries the passphrase and returns both
credentials is the first thing protected rather than the last.
- The panel's CA is pinned and will not silently re-anchor. A change raises a
repair naming both fingerprints and re-pins only on an explicit confirmation.
- Control commands are gated on who is asking, and every one is recorded --
refusals included, which are the entries worth having.
- No control silently swallows a command that did not happen. A refused command
raises where the user made it; so does one the transport never handed over.
- An absent meter reading is no longer read as zero, and a compensation offset
the next reading disproves is retracted rather than kept.
The vendored schema-1 capture is verified against the released
schema-1-v1.1.0 rather than against unreleased bytes, which is the first time
that check has had a release to verify against.

Subject: [PATCH 143/345] docs(changelog): one sentence per entry in 2.1.0
Adds the energy dip fix (#259) and cuts every entry under Changed, Fixed
and Security to a single sentence, without leaning on a dash to bolt a
second clause onto the first. Also drops the paragraph on SPAN's upgrade
timing from the release preamble, which restated what the section above it
already says.
What came out was mechanism and caveat: how the dip was mistaken for a
counter reset, what happens to offsets stored by earlier releases, why a
changed CA cannot be re-pinned automatically, what a refused control used
to do instead. All of it is in the README's Security section and
troubleshooting table, which is where someone chasing one of these looks.
What was kept is what an upgrader cannot find out any other way: which
entities are affected, that ids and history survive, and where a template
reading a moved attribute should now point.

### Changed
- **`DSM Grid State` is now more trustworthy**, reading the islanding state the Microgrid Interconnect Device actually senses rather than inferring it from the
- battery, the dominant power source and which way power was crossing the grid connection. It keeps its entity id and all of its history.
-- **`Grid Islandable` keeps working** across the upgrade: the new firmware publishes no panel-level islandable property and makes the question structural
- instead, so the entity now reflects whether a Microgrid Interconnect Device is present. A panel without one reads `Off`, which is an answer, rather than going
- unavailable.
-- **Battery model** may read differently after upgrading: the new firmware separates the human-readable designation from the SKU, and this entity now shows the
- designation. The normalisation happens in the library on both sides of the upgrade, so it lands once, at this release, rather than unpredictably when your
- panel changes over.
-
-- **Five panel sensors are switched off for new installations** (#234), because the SPAN API documented three defects that predate SPAN firmware r202633: the
- feedthrough energy registers can decrease or go negative, the feedthrough power reading is inverted relative to every other terminal, and the feedthrough
- currents report the _upstream_ service conductors. The affected entities are **Feedthrough Produced Energy**, **Feedthrough Consumed Energy**, **Feedthrough
- Power**, and the two **Downstream** current sensors.
-- **If you already have those five, nothing changes and they stay exactly where they are**, because Home Assistant consults the enabled-by-default setting only
- when an entity is first created — so an existing installation keeps them, keeps its history and keeps its entity IDs. If you use any of the five on a
- dashboard or in an automation they are worth removing, but that is your decision to make, not something an upgrade should do to you.
-- **Your other panel readings are unaffected, and that is now checked against a real panel rather than assumed.** A capture from a live upgraded panel shows the
- four power-flow values summing to zero exactly and the battery power definition byte-for-byte what 2.0.8 shipped, with the upstream lugs, the main panel meter
- and every circuit in the correct frame.
-
-- **New entities are now announced in a notification, whether or not they arrived switched on.** The notification now splits what arrived into ready to use and
- switched off and names each entity.
-
-- **The Wi-Fi network name attribute moved to the Wi-Fi Link sensor**, which is where you would look for it: the entity that tells you whether Wi-Fi is up now
- also tells you which network it is up on, as a `wifi_ssid` attribute. It is absent rather than blank on a panel that publishes no SSID.
-- **It is no longer an attribute of the Software Version sensor**, where a network name never made sense attribute block. If you have a template reading
- `state_attr('sensor.span_panel_software_version', 'wifi_ssid')`, point it at the Wi-Fi Link binary sensor instead.

-- **The three circuit energy sensors are renamed to match the ids they are given**: "Produced Energy", "Consumed Energy" and "Net Energy" become **Energy

- Reauthenticating removes it too, if you upgrade later. **Once an entry reaches version 7, an older build of the integration will refuse to load it** — Home
- Assistant does not downgrade config entries, so roll back from a backup rather than by reinstalling.
-- **New action `span_panel.rotate_credentials`** asks the panel for a new eBus MQTT broker password, stores it, and reloads the integration — for use after a
- contractor visit or a suspected exposure. It is restricted to Home Assistant administrators and cannot be called from an automation or script. **The previous
- broker password stops working immediately**, so any other local client using it must be re-provisioned from the panel. The panel access token and the panel
- passphrase are unchanged, and a failed rotation leaves the existing credentials in place.

+ using the old one.
+- **The panel's certificate authority is pinned before your passphrase is ever sent**, so the registration exchange that carries it — and everything after — no
+ longer crosses your network in the clear.
+- **A changed authority stops the integration and raises a repair** carrying both fingerprints, because a legitimate rotation and an impersonated panel look
+ identical from here.
+- **Four new options decide who may operate the panel** — administrators only, no commands without a logged-in user, an admin-only control lock, and a relay
+ debounce — every one defaulting to what your panel already does.
+- **Every control command is now recorded** in the logbook, on the event bus as `span_panel_control_command`, and at `INFO`, attributed to the automation that
+ issued it rather than to nobody.
+- **Controls now report what happened to them**, so a command that was refused or never handed to the broker no longer looks like one the panel confirmed.
- **A new [Security](README.md#security) section in the README** covers what the integration stores, what rotation costs, and the deployment choices that
- actually bound the panel's exposure — VLAN isolation, a locked enclosure, read-only Home Assistant users, and encrypted backups.
-- **The panel's certificate authority is pinned, before your passphrase is ever sent.** Setup fetches it, checks that the certificate your panel actually serves
- is signed by it, and shows you the fingerprint to accept — and only then asks you to authenticate. Registration is the exchange that carries your passphrase
- and returns both the access token and the broker password, and it used to cross your network in the clear; it now travels over the authority you accepted, as
- does everything after it. Previously the authority was also re-fetched over plaintext HTTP on every connection and whatever answered was trusted. **Anyone
- merely listening on your network can no longer read those credentials.** A device actively impersonating your panel at that first fetch still could, which is
- why the fingerprint is shown for you to compare rather than accepted silently. Panels configured before this release exchanged their credentials long ago and
- are simply pinned on the first startup that reaches them, logged at `WARNING` with the fingerprint.
-- **A changed authority stops the integration and raises a repair** carrying both fingerprints, rather than reconnecting. A legitimate rotation and a device

-- **Every control command is now recorded** — in the logbook, on the event bus as `span_panel_control_command`, and at `INFO`. Commands from an automation are

Subject: [PATCH 144/345] fix(config-flow): pin the panel's authority without
stopping to ask
Setup showed a step headed "Trust this panel's certificate": a 64-character
fingerprint, four paragraphs on what pinning does and does not protect against,
and one button. It asked the user to make a decision they cannot make.
At first contact there is nothing to compare the fingerprint against. SPAN
publishes it nowhere, so the screen said "comparing this fingerprint against
another source is what closes that case" and then offered no source. It also
told them a device standing between Home Assistant and the panel "would still
see them" -- accurate, unactionable, and delivered at the moment they are least
equipped to weigh it. The only available answer was Submit, which makes the
question decoration.
The protection was never in the asking. It is in pinning *before* registration,
so the exchange that carries the passphrase and returns both credentials runs
over a verified connection. That is unchanged: the CA is fetched, the panel's
own certificate is checked against it, and it is pinned, before authentication
is offered. One less step, and the same guarantee.
The fingerprint moves to where it can be acted on rather than acknowledged:
diagnostics report it under `panel_ca`, setup logs it at INFO so the value is
recoverable from the install that pinned it, and the Repair raised if it ever
changes carries both the pinned and the observed value. That last one is the
moment the question becomes answerable, because there is a prior value to
compare against and something has actually happened.
Kept: the error step. A CA that cannot be fetched, or a certificate the panel
serves that its own authority did not sign, still stops setup and offers a
retry -- that failure has a remedy, so it is worth a screen.
`test_the_ca_is_pinned_before_the_passphrase_is_ever_sent` now asserts the
property rather than the screen that used to carry it: when the auth menu is
offered, the panel has been asked nothing yet, and when registration does run
it carries a transport with an SSL context on port 443.

Subject: [PATCH 145/345] feat(config-flow): believe a panel that says where it
serves TLS
The HTTPS-port question exists for an install reaching the panel through
something that moved the TLS port, and it is the right question when nobody
else can answer it. A panel discovered from the simulator add-on is not that
install: the add-on allocates a TLS port per panel and reallocates it across
restarts, so it is the only party that knows, and it now publishes what it
knows -- `https_port` in the Supervisor record, `httpsPort` in the mDNS TXT.
Read both, and skip the prompt when either spoke. Asking after being told is
asking a user to confirm a fact they have no way to check, with the wrong
answer costing them a `ca_leaf_mismatch` and no way past it.
Nothing moves for hardware. Real firmware publishes no TLS port, so the flag
stays false and the gate is what it was: no prompt on port 80, a prompt on a
moved one. A panel behind a reverse proxy advertises `httpPort` and nothing
else, and is still asked -- reading a port from discovery must not become a
way for that install to silently check the CA against 443. An unreadable
value is treated as unpublished for the same reason.
The ports also join the discovery update on an already-configured entry,
since an entry left pointing at last run's ports cannot reach its panel.
The inline TXT parse became `_discovered_port`, which both discovery steps
now share; it keeps the old fallbacks exactly, including 80 for a value that
will not parse.

Subject: [PATCH 146/345] chore: 2.1.0b16
Carries the discovery change: a panel that publishes its TLS port is taken
at its word, so setting up a simulated panel no longer stops on a question
only the add-on could answer. Needs PanelBench 2.2.0 on the other side to
have a TLS port worth publishing.

The integration is moving off presetting entity ids onto supplying one base
per circuit entity and letting Home Assistant compose the rest from the
user's entity_id_parts. The base reads an existing entity's suffix wording
back from its own id, so Recreate proposes it its own id; a new entity gets
the noun-last wording the panel level already uses.

+"""Identity of circuit entities: the base Home Assistant composes an id from.
+
+Since Home Assistant 2026.8 the user decides how an entity id is composed
+(`entity_id_parts`: area, device, entity). This integration no longer presets
+an `entity_id`; it supplies one *base* per circuit entity -- `Circuit 15 power`
+or `Kitchen Outlets power` -- and Core assembles the rest from the user's
+settings. `SpanPanelEntity.suggested_object_id` hands the base to Core.
+
+Two rules bound what the base may be:
+
+- An existing entity must be proposed its own id when nothing changed. Its
+ suffix wording is therefore read back from the id it already has, because
+ this integration has shipped two spellings (`consumed_energy` before it
+ preset ids, `energy_consumed` after). Recreate must never offer a rename
+ the user did not cause.
+- A new entity gets the noun-last wording, which is what the panel-level ids
+ (`main_meter_consumed_energy`) and the display labels use.
+
+The base is *not* the display name. The two are decoupled on purpose, so a
+label can be reworded without touching a single id.
+
+`CIRCUIT_SUFFIX_MAPPING` in `id_builder` builds unique ids and is closed; the
+tables here govern entity ids only.

Subject: [PATCH 148/345] feat(naming): one release of the registry name, for
every name we ever wrote
Three platforms each rebuilt the expected string by hand against only the
description's current label, so a relabel silently stopped the release for
that platform. One helper takes every label the description has carried.

Subject: [PATCH 150/345] feat(sensor): supply a base and let Core compose the
circuit sensor id
The integration no longer presets a circuit sensor's entity_id. It hands
Core one flag-correct base and Core assembles the id from the user's
entity_id_parts, exactly as every non-circuit entity already does. An
existing entity keeps the suffix wording its id already has, so Recreate
proposes it its own id; a new one gets the noun-last wording the panel
level uses. The energy labels return to that wording too, and a name 2.0.8
wrote under either label is handed back.

Subject: [PATCH 151/345] fix(sensor): keep the old id shape for entities the
route change would otherwise move
Handing Home Assistant the job of composing a circuit entity id changes how
two shapes are spelled, for reasons belonging to this integration rather
than to the user: a sensor shown on a sub-device card, whose id names the
panel where composition names the charger, and any circuit entity on an
install with the device prefix off, which has_entity_name prefixes anyway.
Recreate would have offered both moves, and R1 says it must only ever offer
one the user caused. Those entities go on being preset, from current panel
data so a renamed circuit still refreshes the name half; everything new
composes. The registry name release now reads its legacy labels through a
typed narrow rather than getattr, and the two object-id hooks are one.

Subject: [PATCH 152/345] feat(switch,select): supply a base instead of
presetting the entity id
Same shape as the circuit sensors: one base, Core composes, the name an
older release wrote is released through the shared helper.
The breaker switch and the priority select were the last two circuit
platforms spelling their own entity ids. Both now hand Home Assistant an
object-id base -- the naming-flag half plus a suffix each names outright,
"breaker" and "circuit_priority", since `get_user_friendly_suffix` has no
entry for the one and maps the other to the unique_id's spelling.
With the id no longer composed from the display name, the name is free to
be the panel's in both naming modes rather than the mode's on a first
install and the panel's afterwards. It travels as `original_name`, which
ranks below the base, so what is shown cannot decide what "Recreate
entity IDs" proposes -- and an unnamed circuit is named for its tabs
instead of being left to HA, which gave every one of them the same id
stem.
R1's exception is now asked once. The two shapes composition spells
differently -- a sensor on a sub-device card, and any circuit entity on
an install with the device prefix off -- were a sensor-only decision;
three platforms facing the same question with three copies of the answer
is how they drift apart on which entities a release moves. The decision
moves to `naming.legacy_preset_for_existing` and the sensors ask it too,
keeping only the fact a sensor class alone knows: whether this
integration ever preset that entity's id at all.

Subject: [PATCH 153/345] test(naming): one generic install helper for the four
circuit platforms
Four platforms now take the same route into the entity registry, and the
helper that drove them had four copies of it: each of the switch, select
and legacy-energy installs carried its own `load` differing from the
sensor's only in the domain string and the constructor call, plus a
`type: ignore[override]` to excuse a return type the base had fixed to
one platform's entity.
`_Install` becomes generic over the entity it installs and owns the one
`load`. A subclass declares a `_domain` and a `_build`, so a change to the
path under test -- the real `EntityPlatform` add, the `async_reset`
teardown -- reaches all four at once instead of three of them drifting.
The legacy install keeps its registry seeding as its own hook, since
several of its cases exist to test the unseeded path.
No assertion changed. The power-sensor install is now `_SensorInstall`,
the base name having gone to the generic; its call sites moved with it.

Subject: [PATCH 154/345] refactor(naming): delete the preset id builders
construct_single_circuit_entity_id and preserve_legacy_entity_id_suffix are
replaced by naming.circuit_object_id_base; the multi-circuit and unmapped
builders had no callers.
Three things fell out with them. _generate_friendly_name was dead across the
integration -- fourteen implementations existed only to satisfy an abstract
declaration nothing called, since _attr_name has always come from
_generate_panel_name. The `name` constructor parameter on the breaker switch
and the priority select had already been documented as deliberately unused,
so it goes rather than stay as a trap. And sensor_circuit's _LOGGER had no
call sites left.
LEGACY_ENTITY_ID_SUFFIXES is superseded by naming.ENTITY_ID_SUFFIX_FORMS,
which records every wording an id has shipped with rather than only the
pre-preset ones; the paragraph of the three suffix-mapping docstrings that
pointed at it now points at naming.py. CIRCUIT_SUFFIX_MAPPING itself is
untouched -- it builds unique ids and is closed.

Subject: [PATCH 155/345] test(naming): composed ids match the preset shape for
the names a panel carries
Home Assistant slugifies "{device} {base}" as one string; the deleted preset
builder slugified the circuit name alone and joined the parts with `_`. Pins
that the two agree for the names a panel can actually carry -- punctuation,
runs of whitespace, accents -- so no new install diverges from today's shape.
One case disagreed, and the old builder won. Its suffix-omission test was
`circuit_part.endswith(f"_{suffix}")`, with a leading underscore, so a circuit
named exactly "Power" kept both halves and got `..._power_power`.
`circuit_object_id_base` tested without the underscore and would have offered
every such circuit a rename to `..._power` -- a move the user did not cause,
which R1 forbids. The rule now carries the underscore, and "Solar Power" still
omits the word as it always did.
Also drops an unused logger from sensor_panel.py and corrects a test docstring
that claimed every panel sensor takes its displayed name from
`_generate_panel_name`; the constructor does not ask it for a description that
declares a translation_key, whose label comes from translations.

Subject: [PATCH 156/345] test(naming): a SPAN-app rename still reaches the
display name through the reload it requests
Pins phase 2 name sync end to end for sensor, switch and select in both
naming modes, through a real EntityPlatform: the rename asks for a reload,
the reload rebuilds original_name, the entity id does not move, and a name
the user set is left alone.
The README promises this in both modes and the composition change moved where
the name is written, so the promise needed a case that can see the registry.
The per-platform unit tests drive the same code against a MagicMock registry,
which cannot tell `original_name` from `name` -- and writing `name` is exactly
the shortcut that made Recreate propose a friendly-name id for a
circuit-numbered entity.
Each case settles the install with a reload and an unchanged push before
renaming, so the reload it then asks for is the one the rename caused and not
the one every freshly-added entity asks for on its first update.

Subject: [PATCH 157/345] docs: circuit entity ids follow the user's entity-id
settings
The circuit sensors, the breaker switch and the priority select no longer
preset an entity_id; each supplies a base and Home Assistant composes the
rest from entity_id_parts. Record what an upgrading user sees: nothing
moves until Recreate is pressed, what Recreate then offers, the noun-last
energy suffixes for new sensors, the two populations that keep a preset,
the tab fallback for an unnamed circuit, and the device prefix that now
appears in a circuit-numbers install's displayed name.
Drop the 2.1.0 bullet announcing the energy-label rename: the labels are
back to what 2.0.8 shipped, so only the betas ever saw the other wording.
developer.md gains the mechanism -- naming.py as the only place circuit id
wording is written, the suggested_object_id override, the legacy preset and
why R1 requires it, and the release of the registry name field.
The Recreate test whose docstring claims both modes display the new name
now asserts it.

of the report. `tests/test_schema_one_discovery.py` in the library runs the same republish-and-diff experiment this gate uses and holds every entry to it in

+## Circuit entity ids: a base, not a preset
+
+Since Home Assistant 2026.8 the user owns entity id composition — `entity_id_parts` says whether the area, the device and the entity name are in an id, and Core
+assembles it. This integration no longer presets `entity_id` for circuit entities. It supplies one _base_ per entity and Core does the rest, which is how every
+non-circuit entity here has always worked.
+
+`naming.py` is the only place the wording of a circuit id is written down. `circuit_object_id_base(identifier, suffix, existing_entity_id)` joins the
+naming-flag half — `Circuit 15`, `Kitchen Outlets`, `Unmapped Tab 32` — to the suffix wording, and it is the base, not the display name: the two are decoupled
+on purpose so a label can be reworded without a migration. The suffix wording is read back from the id an entity already has, because two spellings have shipped
+(`consumed_energy` before ids were preset, `energy_consumed` after); a new entity gets the noun-last form, matching the panel-level ids.
+`ENTITY_ID_SUFFIX_FORMS` records the forms that have shipped and gains an entry only when another is _discovered_, never to introduce one.
+
+`SpanPanelEntity.suggested_object_id` hands Core that base. It reads `_span_object_id_base`, which circuit entities set and every other entity leaves `None`, in
+which case the property falls through to Core's own answer — composition from the display name, exactly as before. Core consults `suggested_object_id` only for
+an entity that has not preset `entity_id`. The four circuit platforms reach the base by the same route: the sensors through `_object_id_parts`, and the switch
+and the select directly.
+
+### The legacy preset, and why two populations keep one
+
+R1 — "Recreate entity IDs" must never propose a change the user did not cause — bounds what may be composed. Two shapes Core cannot reproduce, for reasons that
+belong to this integration rather than to the user:
+
+- a circuit sensor shown on a **sub-device** card, whose id names the panel because the preset builder always did, where composition names the charger, that
+ being the entity's device;
+- any circuit entity on an install with **`USE_DEVICE_PREFIX` off**, whose id carries no device at all, where `has_entity_name` prefixes one regardless.
+
+`naming.legacy_preset_for_existing` is that whole exception, asked by all three circuit platforms so a copy per platform cannot drift. It answers `None` for
+anything new — an entity with no id yet has none to protect — and `None` for the ordinary existing entity, whose id composition reproduces exactly. Only an
+_existing_ entity in one of the two shapes goes on being preset, and the kept id is **computed from current panel data** rather than read back from the
+registry, so a circuit renamed in the SPAN app still refreshes the name half. That is issue #252, which the preset must not undo. `LEGACY_PRESET_DEVICE_NAME` is
+the literal `Span Panel` the old builder spelled every circuit id with — not the panel's own name, which is why a second panel's circuits are `span_panel_…`
+too, and why keeping an id means keeping that spelling.
+
+### Releasing the registry name
+
+Circuit-numbers mode used to deliver the panel's circuit name by writing the entity registry's `name` — the _user's_ field, which Core reads ahead of everything
+else when generating an entity id, so occupying it made Recreate propose a friendly-name id for a circuit-numbered entity.
+`naming.release_registry_name_written_by_older_release` hands that field back at the first start after upgrading. It clears only a value this integration would
+have written — `"{circuit_name} {description name}"`, for the description's current label and every label it has carried, which is what
+`SpanPanelCircuitsSensorEntityDescription.legacy_names` exists to record. Anything else in that field is the user's and is left alone.
+
+The display name now travels as `original_name` via `_attr_name` for both modes, which means a rename pushed from the SPAN app is picked up by rebuilding the
+entity: `_sync_circuit_name` asks the coordinator for a reload rather than writing the registry in place. It skips both the reload and the name where the
+registry holds a `name`, since the user's field outranks the panel's and reloading could not change what is displayed.
+
## The suffix mappings are closed
`get_user_friendly_suffix` and `get_panel_entity_suffix` translate legacy camelCase description keys (`instantPowerW`, `instantGridPowerW`, `doorState`) into
the suffixes their entities have carried since before 2.0.8. **Do not add entries.** A new description key needs none: it resolves to itself, which is what the
sub-device builders (`build_bess_unique_id`, `build_mid_unique_id`, `build_evse_unique_id`) have always done, since their keys were written snake_case.
-The reason is that the suffix is not only in the `unique_id` — it is the segment shared with the `entity_id` (`sensor_circuit.py:213`, and
-`get_panel_entity_suffix`'s own docstring says so). So an edit here moves both on every installed panel: the `unique_id` costs the long-term statistics, and the
-`entity_id` breaks whatever templates and automations a user wrote against it.
+The reason is that the suffix is not only in the `unique_id` — it is the segment shared with the `entity_id` (it is the `suffix` half of

`tests/test_suffix_mappings_are_closed.py` holds all three dictionaries to their exact contents and fails on an added key, a removed key or a changed value —
verified by mutation, not by inspection.

Subject: [PATCH 158/345] docs: say exactly what the release does to the
registry name field
The Changed bullet claimed the integration never writes or clears the
registry name, which the Fixed bullet two lines down contradicts: the
release does clear the value 2.0.8 wrote. Say the narrower true thing.
Also: the displayed-name example uses the default device name Span Panel;
the EVSE feed-circuit wording is "sensors created from this release on",
since a charger added later to an existing install composes too; and the
entity-id settings are named by their key rather than by a menu path
nobody has verified against the 2026.8 frontend.
developer.md gains the fact most likely to be "simplified" away later --
Core files suggested_object_id as object_id_base, which the user's parts
prefix, while a preset entity_id becomes a verbatim unprefixed suggestion
that outranks it -- plus the third gate keeping the unmapped-tab sensors
off the preset path, and the platform count corrected to three.

Subject: [PATCH 159/345] fix(naming): keep ids on generated panel names, and
read the suffix back anchored on the circuit
Two ways "Recreate entity IDs" still offered a move nobody asked for (R1).
The config flow names the panel device: the second panel on a system becomes
"Span Panel 2" without anyone typing it. Composition spells the device half
from that name, while every circuit id already on that panel says
`span_panel_` -- the literal the deleted preset builder fell back to, since it
was never told the panel's name. So the whole panel was offered
`sensor.span_panel_2_...`. The preset exception now covers a generated device
name that is not "Span Panel", read from the registry's `name`. A name in
`name_by_user` is the user's and still composes, because Home Assistant
composes from `name_by_user or name` and following that is following the user.
The suffix half was read back from the end of the existing id and the omission
rule decided from the identifier alone, so the two could disagree with the id
they were meant to reproduce. A circuit named "Current" had
`..._current_power` read as the `current_power` form and was offered
`..._current_current_power`; a circuit named "Solar Power" whose id kept both
halves was offered `..._solar_power`. Both questions are one question, so
where the id still names the circuit they are answered together, anchored on
the identifier: what follows the name is the form, and a name the id stops at
means the form was omitted. A circuit renamed on the panel is unchanged --
its id no longer names it, so the suffix is read from the end as before and
the name half follows the panel, which is issue #252.

Subject: [PATCH 160/345] security(config-flow): pin the CA on reauth before
the passphrase is sent
Reauth builds its REST transport from the entry's stored data, and an entry
with no usable pin got a plaintext one. Registration is the exchange that
carries the panel passphrase and returns the eBus broker password, so on
those entries the credentials crossed the network in the clear -- the exact
thing pinning before registration exists to remove, and the opposite of what
the release notes tell upgrading users.
Three populations reach reauth unpinned: entries still recorded as
api_version "v1", which fail setup before the deferred fetch can run and
which the v7 migration does not flag; v2 entries missing their broker
credentials, which fail setup the same way; and entries whose deferred fetch
failed. A fourth, an entry whose stored PEM no longer loads, falls back to
plaintext in panel_rest_transport and is now re-pinned as well.
Reauth of such an entry now routes through the CA step -- fetch, leaf check,
adopt -- and only then shows the reauth menu, so both authentication methods
register over the anchor. A leaf that does not chain shows ca_leaf_mismatch
with no way past, as on install. _update_v2_entry keeps the acquired CA and
clears the pending flag, so the entry stays pinned instead of falling back to
a plaintext CA fetch on every connect. An entry that already carried a usable
pin is untouched and skips the step.
The entry's stored HTTPS port is adopted on reauth so a panel behind a proxy
is not asked again for a port it already recorded, and is persisted alongside
the CA when the user does have to name it.

Subject: [PATCH 161/345] fix(config-flow): bootstrap an FQDN install over the
address the leaf actually names
A panel's certificate names the addresses it already knows itself by -- its IP
and its .local name. An FQDN joins that list only when register_fqdn tells the
panel to regenerate the leaf, and that runs after authentication. Every check
before it was made against the FQDN with hostname verification on, so it failed
on the one thing that could not yet be true.
Two flows were unusable as a result. A fresh install named by FQDN died at the
CA step with ca_leaf_mismatch, which is deliberately a dead end with no way
past, so the install could not complete at all. Reconfiguring a pinned entry to
an FQDN died one step earlier: detect_api_version dialled the new name under the
stored anchor and reported cannot_connect. Neither was caught because every FQDN
test in the suite ran under an autouse fixture that stubs async_leaf_chains_to_ca
and build_panel_ssl_context, so hostname verification was never exercised.
The pre-registration bootstrap now dials the panel's resolved address: the CA
fetch, the leaf check, registration, and the FQDN request itself. Hostname
verification is not relaxed anywhere -- the address checked against changed, the
check did not, and a leaf the published CA does not sign is refused exactly as
before. A name that will not resolve falls back to dialling the name, which is
what shipped. Only once the panel reports the regenerated certificate is the
FQDN verified, on the broker port and again on the port the entry will store,
before anything is persisted.
check_fqdn_tls_ready took the anchor it verifies against by refetching the CA
over plain HTTP every two seconds, which is a fresh trust decision on each poll
against whatever answered -- and anything that can answer it can also serve a
leaf signed by the CA it just handed over. It now takes the pinned PEM, carried
on PanelRestTransport beside the context built from it. The plaintext fetch
survives only for a reconfigure of an entry that never acquired an anchor.
Folded in, from the review of the reauth pinning that preceded this:
validate_v2_passphrase and validate_v2_proximity now require a transport instead
of defaulting to a plaintext one, so the calls that carry the passphrase and
return the broker password cannot be made unpinned by omission; the proximity
pre-check, which decides whether the door challenge is believed, runs over the
pin rather than an unverified client; a reauth that replaces a stored PEM this
system can no longer load logs the new fingerprint at WARNING; and a stored
HTTPS port counts as known only when it could actually be read, rather than when
a default was substituted for it.

Subject: [PATCH 162/345] refactor(naming): the base never bypasses
entity_id_parts
R1 was clarified on 2026-08-26 (evening) in the circuit-numbers spec:
The base must reproduce an existing entity's id *when Home Assistant
composes it under the entity-id options that match how that install was
built*. That is what "never offer a rename the user did not cause" means:
the base carries the install's own suffix wording (`consumed_energy` or
`energy_consumed`, read back from the id) and the circuit's own name, so
two spellings of ours or a relabel never produce an offer. It does **not**
mean bypassing Home Assistant's `entity_id_parts` with a hard-coded id:
where composition yields a different device part (an EVSE feed sensor on
the charger's card, a second panel named "Span Panel 2", an install with
the legacy no-prefix option), that is Home Assistant's configuration at
work and the offer is legitimate. The "legacy preset" exceptions added
during implementation on 2026-08-26 are therefore withdrawn. Nothing moves
an id without the user pressing Recreate.
Withdrawn accordingly:
- naming.py: LEGACY_PRESET_DEVICE_NAME, generated_panel_device_name,
legacy_preset_entity_id, _names_another_device, legacy_preset_for_existing,
and the now-unused dr / HomeAssistant / DOMAIN / Final imports. The module
docstring states the clarified rule.
- entity.py: _generated_panel_device_name.
- sensor_base.py: _preset_composition_would_move,
_id_was_preset_by_this_integration, the `self.entity_id = preset` branch and
the USE_DEVICE_PREFIX import. The base is set whenever _object_id_parts
returns parts and the entity is not a sub-device.
- sensor_circuit.py: both _id_was_preset_by_this_integration class attributes.
- switch.py, select.py: the legacy_preset_for_existing call, the preset branch
and the USE_DEVICE_PREFIX read. _span_object_id_base is always set.
No `self.entity_id = ...` remains in the four circuit platforms; Home
Assistant composes every id from the user's entity_id_parts.
Kept, because they are base fidelity rather than a bypass: the per-install
suffix read-back, the identifier-anchored form test, and the sub-device
sensors that supply no base and compose from their label on the charger.
Tests: the "offered its own id" cases for a sub-device sensor, a no-prefix
install and a generated "Span Panel 2" panel now assert what Home Assistant
composes under (DEVICE, ENTITY) parts -- sensor.span_panel_ev_charger_power,
sensor.span_panel_refrigerator_power, sensor.span_panel_2_refrigerator_power
and the two control equivalents -- and that the live entity_id is unchanged
after two reloads (R5). The unit tests of the deleted symbols are gone; every
suffix read-back, rename and circuit_object_id_base case is unchanged.
README, developer.md and the 2.1.0 changelog describe the base and the
read-back only, and say that these three populations may be offered the
composed id, their entity-id settings deciding, with nothing moving until
they accept.

-R1 — "Recreate entity IDs" must never propose a change the user did not cause — bounds what may be composed. Two shapes Core cannot reproduce, for reasons that
-belong to this integration rather than to the user:
-
-- a circuit sensor shown on a **sub-device** card, whose id names the panel because the preset builder always did, where composition names the charger, that
- being the entity's device;
-- any circuit entity on an install with **`USE_DEVICE_PREFIX` off**, whose id carries no device at all, where `has_entity_name` prefixes one regardless.
-
-`naming.legacy_preset_for_existing` is that whole exception, asked by all three circuit platforms so a copy per platform cannot drift. It answers `None` for
-anything new — an entity with no id yet has none to protect — and `None` for the ordinary existing entity, whose id composition reproduces exactly. A third gate
-sits in front of it on the sensor side, `_id_was_preset_by_this_integration` (`sensor_base.py`, set to `True` only by the circuit sensor classes): the hidden
-unmapped-tab sensors have had their ids composed by Home Assistant all along, and an id Core already composes cannot be moved by handing Core the job, so they
-never reach the preset path. Only an _existing_ entity in one of the two shapes goes on being preset, and the kept id is **computed from current panel data**
-rather than read back from the registry, so a circuit renamed in the SPAN app still refreshes the name half. That is issue #252, which the preset must not undo.
-`LEGACY_PRESET_DEVICE_NAME` is the literal `Span Panel` the old builder spelled every circuit id with — not the panel's own name, which is why a second panel's
-circuits are `span_panel_…` too, and why keeping an id means keeping that spelling.
+### What R1 bounds, and what it does not
+
+R1 — "Recreate entity IDs" must never propose a change the user did not cause — bounds the _base_ and nothing else. Read exactly: the base must reproduce an
+existing entity's id **where Home Assistant composes it under the entity-id options that match how that install was built**. That is why the suffix wording is
+read back and why the name half is anchored on the circuit's own name: two spellings of ours, or a relabel, must never produce an offer.
+
+It is **not** a licence to bypass `entity_id_parts` with a hard-coded id. Where composition yields a different device half — a SPAN Drive feed sensor, whose
+device is the charger and not the panel; a second panel the config flow named "Span Panel 2", whose circuit ids all say `span_panel_` because the old builder
+was never told the panel's name; an install with `USE_DEVICE_PREFIX` off, whose ids carry no device at all where `has_entity_name` prefixes one — that is the
+user's own configuration at work, and the offer is legitimate. Recreate offers it; nothing moves until the user presses the button (R5). The "legacy preset"
+exceptions written for those three shapes were withdrawn by the maintainer on 2026-08-26, and there is no `self.entity_id = …` left in any of the four
+platforms.
+
+One consequence worth naming: a circuit sensor on a sub-device card supplies **no base at all**. Its label there is the bare description name (`Power`), so it
+composes as `sensor._power` like the charger's own sensors, and a rename on the panel cannot reach its id. Every other circuit entity sets its base
+whenever `_object_id_parts` answers.

Subject: [PATCH 163/345] docs: existing EVSE feed sensors compose like any
other on Recreate
The EVSE naming section still described the withdrawn exemption -- "sensors
that already exist keep the IDs they have, which name the panel". Nothing
keeps an id any more: a feed sensor's entity id names the charger, and an
existing one is offered that id when the user presses Recreate.
developer.md now states plainly that the suffix read-back does not reach
sub-device sensors. It lives in circuit_object_id_base, which a sub-device
sensor never calls -- with no base, Core composes the entity half from the
description label. An existing feed energy sensor spelled `..._energy_consumed`
is therefore offered `sensor._consumed_energy`, both halves changing,
and that is by design: reading a base back for these is the bypass the
clarified R1 forbids.
README also carried the R5 sentence twice over two paragraphs; it now appears
once, in the paragraph that describes the offer.

Subject: [PATCH 164/345] fix(config-flow): never persist a pinned host the
leaf does not name
Bootstrapping over the panel's address got FQDN installs working again, but it
also let the flow reach entry creation with a host the pinned certificate does
not name -- and then write it. An entry like that cannot reach its own panel:
every REST call and the MQTT connection dial the recorded host under the stored
anchor, and the anchor rejects it. The address was standing in for a name that
was never made to work, and nothing downstream could tell the difference.
Three ways in. "Continue anyway" after a failed registration recorded the domain
the panel had just refused to serve, and recorded CONF_REGISTERED_FQDN with it,
because that key was derived from is_fqdn(host) rather than from whether the
registration succeeded. A single-label name -- one a search domain resolves, or
the hostname an add-on serves under -- is never registered by anything, because
is_fqdn is false for it, so it went straight from authentication to entry
creation. And a reauth of an unpinned entry whose host is an FQDN acquired the
anchor over the address and stored it beside the host, unverified.
_bootstrap_host now carries one invariant: it is set only while self.host is a
host the pinned leaf does not name. Every route that persists a host reads it
and refuses -- ca_leaf_mismatch on install and reauth, on the reconfigure form
for a simple host change -- and registration, the one thing that can make the
panel start serving a name, clears it when the panel does. "Continue anyway"
keeps the panel rather than the name: it records the address that got that far,
claims no FQDN registration, and both screens now say so. The domain can be
tried again from Reconfigure once whatever blocked it is fixed.
The chooser also stops preferring the address over the host it was given. The
host is tried first, always, and only a host the leaf does not name falls back
to the resolved address. A panel that already names the host in its certificate
-- an add-on hostname, an mDNS name, an FQDN a previous install registered --
keeps being reached by it, where preferring the address would have swapped a
working host for one the certificate may not name at all.
Also: getaddrinfo raises UnicodeEncodeError, not OSError, for a label over 63
characters, because IDNA encoding fails before any lookup is attempted. Both the
resolver and the leaf check now catch UnicodeError, so a host typed into a form
cannot end the flow in a traceback.

Subject: [PATCH 165/345] fix(control): the control lock keeps its state across
a reload
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
`ControlLock` was a plain object rebuilt by every `async_setup_entry` and
`SpanPanelControlLockSwitch` was not a `RestoreEntity`, so every options save,
credential rotation, circuit rename and restart silently disarmed the lock and
showed the switch off with no notice. It also arrived disarmed on a fresh
install, contradicting the option text's promise that the feature keeps the
lock armed until someone disarms it.
The lock is now constructed armed whenever the feature is on, which also closes
the window between the interceptor being installed and the platforms being
forwarded, and the switch restores a previous run's disarm into it — into the
lock, never alongside it, so the interceptor and the entity cannot disagree. A
pending auto-relock is persisted as a wall-clock instant and resumes with the
time it had left; restarting the window would let a reload every few minutes
hold the lock open indefinitely. The relock also writes state when it falls due
instead of only settling on the next read, which nothing performed on a
schedule.
Also corrects the comment describing a zero timeout, which had the semantics
backwards.

debounce — every one defaulting to what your panel already does.
+- **The control lock arrives armed and stays where you left it**, so turning the option on locks control straight away and a restart or a settings save no
+ longer quietly unlocks the panel; a pending auto-relock comes back with the time it had left rather than starting its countdown over.
- **Every control command is now recorded** in the logbook, on the event bus as `span_panel_control_command`, and at `INFO`, attributed to the automation that
issued it rather than to nobody.
- **Controls now report what happened to them**, so a command that was refused or never handed to the broker no longer looks like one the panel confirmed.

Subject: [PATCH 166/345] fix(control): one outcome path for every control,
adopted ones included
The try/except/outcome block that turns a library refusal and a FAILED
`PublishOutcome` into a translated `HomeAssistantError` had been hand-copied
into four platforms and left out of the fifth. An adopted device's switch,
select or number awaited `set_adopted_property` and discarded what came back:
a FAILED outcome -- "broker not connected; refused rather than queued", or a
closed transport -- returned normally and refreshed, so a command that was
never handed over looked exactly like one the panel confirmed, and a refusal
propagated as a raw `SpanPanelServerError` with no translation key.
`SpanPanelEntity._async_control` now states both facts once, wrapping the
caller binding that `_async_guarded_control` already owned, and every control
in the integration goes through it: relay, priority, charge-current limit, GFE
override, and any settable property on an adopted device. The curated keys and
placeholders are unchanged, so no existing message moves; adopted controls get
two of their own, naming the property and the device in the wire vocabulary
that is the whole identity such a device has.
The select keeps its `ServiceNotFound` branch outside the helper rather than
offering it to controls that have never needed it. The library imports Home
Assistant nowhere, so nothing on the publish path can raise it today.

- **Every control command is now recorded** in the logbook, on the event bus as `span_panel_control_command`, and at `INFO`, attributed to the automation that
issued it rather than to nobody.
-- **Controls now report what happened to them**, so a command that was refused or never handed to the broker no longer looks like one the panel confirmed.

- **A new [Security](README.md#security) section in the README** covers what the integration stores, what rotation costs, and the deployment choices that
actually bound the panel's exposure.

Subject: [PATCH 167/345] fix(adoption): a vendor format we cannot parse yields
a reading, not a crash
`parse_number_format` called `float()` on the declared `$format` with no
guard, and `classify` routed any settable numeric with a truthy format to
NUMBER. A non-compliant publisher spelling a range `"0-100"` or `"auto"`
therefore reached `AdoptedNumber.__init__`, where the ValueError escaped
`create_adopted_numbers` into `number.async_setup_entry` -- before its only
`async_add_entities` call, so the whole number platform failed and no entity
was created at all. That included the curated EVSE charge-current limits: one
vendor device on a schema that is explicitly vendor-extensible cost the user a
control on hardware this integration models.
`parse_number_format` now answers None rather than raising, for anything
`float()` refuses and for non-finite bounds, which parse and are still not
bounds. `classify` asks it instead of testing the string, so the platform
decision and the bounds a number is built from cannot disagree: an unreadable
range is no range, and the property surfaces as the reading it can still be.
A format Homie permits parses exactly as it always did.
`AdoptedNumber` raises on absent bounds rather than defaulting to 0-100, which
would offer a control the panel never declared, and `number.async_setup_entry`
adds the curated numbers in their own call before adoption is attempted --
ordering rather than a handler, so that any future fault in adoption stops at
the adopted entities without five platforms each restating a try/except.

Subject: [PATCH 168/345] security(ca): never pin a CA that does not sign the
panel's own certificate
The config flow proves the CA it fetched signs the certificate the panel
serves before pinning it. The two pins that happen outside the flow did
not: the deferred fetch at setup, which settles the flag the v7 migration
leaves on an upgraded entry, and the CA-changed repair, which asks a
person to accept a new authority. Both stored whatever the plaintext,
unauthenticated fetch returned.
Anything on the path can answer that fetch. A reverse proxy in front of
the panel answers it with an authority of its own, and pinning that is
not a recoverable mistake: the broker connection then fails against a
certificate the pin rejects, the change diagnosis finds the fetched CA
and the pinned one identical and so reports no change, and the entry
retries forever with no repair to offer and diagnostics saying it is
pinned.
Both sites now check the fetched CA against the certificate served on the
entry's TLS port, through one helper that carries the config flow's
address fallback -- the panel's leaf names the addresses it knows itself
by, so a host recorded as a name is also tried by the address it resolves
to. A refused deferred pin is treated exactly as a failed fetch: nothing
stored, the flag kept for the next setup, and the entry continues
unpinned rather than losing its integration. A refused re-pin aborts the
fix flow with `ca_leaf_mismatch` and leaves the standing pin alone; the
issue stays raised, so the repair can be run again. The user is never
shown the fingerprint of a value that already failed.
The real-TLS harness moves out of the config-flow test module so the new
tests can use it: a throwaway CA, a leaf served from a loopback listener,
and the refusal proved by a handshake rather than by a stub.

Subject: [PATCH 169/345] security(ca): verify the pin against the port it
guards
The leaf check added with the deferred pin ran against `https_port`. That
key and `panel_ca_pending` arrived in the same commit, so an entry
carrying the flag is by definition migrated from before either existed
and can never hold one: every deferred check ran against 443. A
pre-pinning install whose panel serves TLS somewhere else -- behind a
port forward, a NAT rule, a proxy -- was refused on every setup, kept the
warning it could not act on, and stayed on the unauthenticated
refetch-per-connect path for good. That is the one population the
deferred pin exists for, and at base those entries pinned and then
connected, because the broker is dialled on `ebus_broker_mqtts_port`.
Both sites now check the CA against the broker's port, which is on every
v2 entry by construction -- setup refuses one without it before the pin
is reached -- and is the connection the anchor is actually used for. The
repair moves with it for the same reason: it exists to restore that
session, so that is the certificate its offer has to be good for.
Also fixes the warning, which named the port twice and described it as
the panel's TLS port, and records at the call site the asymmetry that
remains: the check accepts a leaf reached at the address the host
resolves to, while the bridge dials the host itself, so a certificate
naming only the address pins here and fails hostname verification at
connect. Pre-existing, and the config flow bootstraps the same way.

Subject: [PATCH 170/345] security(discovery): a pinned entry follows a
discovered host only when its certificate chains to the pin
The abort that says a panel is already configured is also how an entry
follows its panel to a new address, and both routes into it -- an mDNS
_ebus._tcp announcement, and a user re-adding a panel by hand -- reach it
before anything has been authenticated. The serial that matched came from
the candidate host's own unauthenticated /api/v2/status, so any device on
the LAN could claim a panel's serial and have the entry rewritten to point
at itself; MQTT then failed verification against the pinned authority and
the CA-changed repair invited the user to accept the impostor's
fingerprint.
The same rewrite broke honest installs the other way round: re-adding an
already-configured panel by an unregistered FQDN or a single-label name
stored that host on an entry whose own anchor rejects it, leaving an entry
that could not reach its panel and no flow left to correct it.
A pinned entry now asks the one question only the panel can answer -- does
the candidate serve a certificate this entry's anchor validates, on the
port the entry uses -- and carries the host update only when it does,
refusing at WARNING otherwise. The host is checked as it would be stored,
without the resolved-address fallback the bootstrap uses, because accepting
a name on the strength of its address would persist exactly the host that
fallback refuses to write. An entry with no anchor has nothing to check
against and keeps the behaviour it shipped with.

Subject: [PATCH 171/345] refactor(config-flow): one implementation of which
address reaches the panel
`_async_choose_bootstrap_host` and `async_ca_signs_panel_leaf` had grown the
same ten lines: try the host as given, and only if its certificate does not
name it, try the address it resolves to. The flow's copy existed because it
needs to know *which* candidate answered, not merely that one did.
Give the shared helper that answer. `async_panel_leaf_host` returns the
address the panel was reached on, `async_ca_signs_panel_leaf` becomes the
boolean reading of it for callers that only want the verdict, and the flow
keeps only what is genuinely its own: recording the substitution in
`_bootstrap_host`, which is what lets every later step refuse to persist a
host the pinned anchor rejects.
No behaviour change. The tests that drove the flow's candidate logic move
with the seam -- they patched the leaf check inside it, and now patch the
helper that performs it; the port they assert on shifts one position because
the shared signature takes `hass` first.

Subject: [PATCH 172/345] fix(services): rotate_credentials names its panel,
reports a failed reload, and never downgrades to plaintext
Three defects in one service, all of them about a call that invalidates a
credential and cannot be taken back.
With no `config_entry_id` the handler took the first loaded v2 entry it
found. Rotating stops the previous broker password working for every other
local client of that panel, so a multi-panel admin who omitted the field
broke a panel they did not name. More than one loaded panel is now refused
as ambiguous; a single panel stays unambiguous and keeps the field optional.
`async_reload` returns whether the entry came back, and its result was
dropped: the service logged "Rotated" and reported success even when the
integration never reloaded onto the new password. It now raises, and the
message says the password was stored so nobody rotates a second time and
invalidates the one the panel has already accepted.
`panel_rest_transport` falls back to plaintext when a stored PEM will not
parse, which is right for a caller whose alternative is not working at all
and wrong for this one: the rotation carries the access token out and the
new broker password back. The transport helper grows an
`allow_plaintext_fallback=False` opt-out that raises `PanelCaUnusableError`
instead of downgrading, and the service refuses rather than sending secrets
unverified. An entry with no stored CA at all is not pinned in the first
place and keeps the plaintext transport it has always used.

Subject: [PATCH 173/345] test(services): rotate_credentials tests pass ruff,
and two wording nits
The test file was excluded from the repo's own ruff hooks and had drifted:
one unsorted import block and six nested `with` statements. Sorted and
folded into parenthesised context managers, including the five that predate
this task's tests. No behaviour change; the same 13 tests pass.
The in-code fallback message for `rotate_credentials_ca_unusable` said what
went wrong but not what to do about it, while the translated string carried
the remedy. Anyone reading the untranslated fallback got the worse half.
`PanelCaUnusableError` subclasses `ValueError`: an unparseable stored value
is what it is, and `build_panel_ssl_context` already raises `ValueError` for
the same condition, so a caller catching that around either function keeps
catching this one.

Subject: [PATCH 174/345] fix(coordinator): a dead transport makes entities
unavailable, not zero
A CA change mid-session marked the panel offline before raising
UpdateFailed, and offline is the flag that tells entities to keep
answering: `available` returns True on that branch ahead of
`last_update_success`, so every sensor stayed available, POWER sensors
reported 0.0 and energy sensors held their grace values -- indefinitely,
since nothing retries and re-pinning requires a person. A dashboard
cannot tell that from a live reading of a panel drawing no power.
Offline now means only what its consumers assume: a gap that closes.
`transport_dead` is the separate fact -- set from the library's
fatal-error channel and from the CA branch, cleared by a connection edge
back to connected -- and every platform's `available` consults one helper
on `SpanPanelEntity` ahead of whatever it does about offline, so the six
copies of that decision cannot drift apart again.
`panel_status` is the single exception, because it reports reachability
and so has to survive the condition it reports; it reads the flag
directly and goes off rather than holding a stale on.

Subject: [PATCH 175/345] fix(dip): a confirmed dip that then returns to its
baseline is still retracted
Confirmation cleared the pending record, so the offset became permanent on one
tick of apparent progress. A debounced snapshot burst can deliver two stale
samples, the later one higher, which is indistinguishable from a counter
climbing away from a fresh base: 1000 -> 0 -> 5 -> 1001 booked the whole
lifetime counter and left a +1000 Wh step in long-term statistics, where undoing
it is a manual per-hour adjustment.
Confirming now keeps the record for three further readings, during which a
return to the baseline retracts everything; when the window is spent the record
is dropped and the offset is final. A further fall inside the window
accumulates against the original baseline and spends a reading rather than
reopening it. The remaining window is persisted alongside the record, so a
restart neither loses the retraction nor extends it; stored data written before
the field existed restores as an unsettled dip, which is what it was.

Subject: [PATCH 176/345] fix(sensor): do not present a default as the
at_service_entrance reading
The grid power sensor published `at_service_entrance` from
`SpanPanelSnapshot.lugs_at_service_entrance`, which is a plain `bool`
defaulting to True. Only the parent/child adapter ever writes it -- from
the upstream lugs' own `connection/fed-by-device-id` -- and the flat
adapter does not reference the field at all. A flat panel therefore
reported True whatever its topology, including the BESS-ahead-of-the-lugs
case the attribute exists to report, and reported it as a reading.
The attribute is now published only where the running adapter resolved
it. Omission rather than a third value: nothing renders a missing
attribute, so a flat panel looks as it did before the attribute existed,
whereas an `unknown` string would be a new row meaning "ignore me". The
test is where the value came from, never what it is, so a panel that
genuinely is at the service entrance still reports True.
Asked of the adapter rather than of the field metadata, which is how
every other "did the adapter produce this" question here is settled: a
metadata row states a reading's unit and datatype, and this field's
backing property is topology, so schema_1 lists it in
`_CONSUMED_WITHOUT_A_ROW` and neither adapter emits a row. The map is
silent for the panel that resolved the field and for the panel that never
looked, which is exactly the distinction needed. This is a workaround for
a library type and is meant to be deleted: once span-panel-api makes the
field `bool | None`, the honest test is `is not None` on the value.
Tests drive the real adapters rather than the snapshot factory, so the
claims are about the adapters: a new `schema_zero_snapshot()` fixture
builds a flat snapshot, and the vendored parent/child capture already
carries `lugs-upstream/connection/fed-by-device-id = bess`.

Subject: [PATCH 177/345] fix(dip): a dip inside a confirmed window is judged
against its own baseline, and the reset is reported when it settles
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Folding a dip that arrives inside a corroborated dip's retraction window into
that dip's record measured the newcomer against the older high-water mark. A
3 Wh replay booked while a 1000 Wh dip was still open could then only be
retracted by the counter returning all the way to 1000, which it cannot do
inside the window: `1000 → 0 → 5 → 2 → 6 → 7` left the 3 Wh compensated for
good. The two dips are now kept apart, each judged against its own baseline, so
that sequence gives the 3 Wh back and keeps the 1000. A fall does not buy the
older dip's window more readings, and corroborating the newer dip settles the
older one rather than merging it, so the bound stays three readings from the
most recent corroboration.
The notification also moves from corroboration to settling. Corroboration is
evidence, and the readings just after it can still retract the dip, but a
persistent notification cannot be retracted — so a dip that was reported and
then undone left the user with a notice for an event that did not happen, which
is what reporting on sight did in SpanPanel/span#259. `DipEvent.SETTLED` marks
the reading that closes the window, and `DipOutcome.settled` carries the amount
separately from `event` because a dip can settle on the same reading that books
or retracts another one.
Both records persist across a restart with the window's remaining readings, so
a restart neither loses the retraction nor renews it, and the report still
arrives when the dip settles afterwards.

Subject: [PATCH 178/345] test(sensor): pin the at_service_entrance adapter
gate to the installed adapter keys
`_SERVICE_ENTRANCE_ADAPTER` names the adapter whose mapper resolves
`lugs_at_service_entrance`, and nothing held that name against the
adapters. A renamed key would have matched no panel, made every install
look like an adapter that does not resolve the field, and dropped the
`at_service_entrance` attribute with no error, no unavailable entity and
nothing in the log.
The assertion goes in the conformance module because that is what the
module is for: its docstring says a statement about which adapters
produce a field is checked against the adapters rather than left as
prose, and this constant is the one such statement made outside
`RESIDUAL_EXEMPT_PATHS`. Read off the adapter classes, since
`SpanMqttClient.schema_major` returns the class attribute and a class
needs no connection.
Both halves are load-bearing. The `==` catches a renamed key silently
dropping the attribute; the `!=` catches the constant naming the flat
key, which would publish the library's `True` default on every flat panel
-- the defect the gate was added to fix.
Also makes the new `schema_zero_snapshot` docstring imperative, which
D401 asks for and its sibling `schema_one_snapshot` already is.

Subject: [PATCH 179/345] fix(control): debounce only delivered commands,
refuse under DISABLED, follow settability changes
The relay debounce stamped its window in `before_publish`, so a command the
broker never took still refused the user's immediate retry with "that circuit's
relay was operated less than 2 seconds ago" -- false, and unactionable at
exactly the moment a person presses the button again. The stamp moves to
`after_publish` and is recorded only for an outcome that is not FAILED, which is
the one state promising the command will never arrive; the synchronous check
stays in `before_publish` where the veto has to happen.
`ControlMode.DISABLED` was enforced only by not creating entities. That is what
a user sees, not a choke point, and the module opens by promising one. The gate
now refuses under `disabled` with a translated `control_disabled` and a logbook
phrase. No entity path changes: all four control platforms already create
nothing under `disabled`, and no service publishes a control.
`is_user_controllable` and `is_never_backup` were read once, at setup, so an
entity could outlive its own settability -- the case the library's changelog
names -- and go on offering a control the panel refuses every use of. Each
platform's creation rule is now one predicate, read by `async_setup_entry` and
by the entity, and the entity asks for a reload when the answer moves. The
opposite edge, a circuit that becomes settable, still needs a reader that sees
every circuit; the coordinator is where that belongs.
Also, from the reviews of the two preceding control commits: a restored disarm
whose pending window cannot be read now arms the lock rather than granting a
fresh one, since a restart is not consent to operate the panel; the runtime
data's default lock is derived from the default policy instead of being a bare
disarmed object; and the `ServiceNotFound` branch in the priority select is
removed with its notification and its test, the MQTT client having no way to
raise it.

Subject: [PATCH 180/345] fix(adoption,extension,additions): five robustness
defects from the release review
Adopted unique_ids are not injective: flattening the hyphens collapses
`battery-2/cell-temperature` and `battery/2-cell-temperature` onto one id, and
Home Assistant drops the loser permanently with only a core log line naming an
id the user cannot map back to the wire. The encoding does not change -- an
adopted unique_id is as permanent as a curated one, so the injective form would
move every id an install already holds -- so `_create` claims one id per
platform, keeps the first property to reach it, and skips the second with a
WARNING naming both wire paths. The injective encoding is recorded as a
follow-on for the next identity namespace.
Adoption lacked the 255-character state clamp `9567cb9` added to extension, so
an unbounded vendor string reached the state machine verbatim: core substitutes
`unknown` and logs an error on every update, which loses the reading entirely.
One `clamp_state` now serves both halves of vendor extensibility.
The additions store did no shape narrowing, and it is read from inside
`async_setup_entry`: a wrong-shaped file raised out of it, shut the coordinator
down and failed the entry with no retry. It is now narrowed exactly as
`notices._load` is, and a bad shape re-seeds with a WARNING.
The extension-overflow notice was raised through `async_raise` on a condition
re-derived at every setup, so it returned after every dismissal -- un-dismissable
in practice, and the opposite of what `notices.py` promises. `async_raise_on_change`
records what was announced in the notices store, and the notice returns only when
the declined set changes. The record deliberately outlives dismissal.
Adopted devices and extension properties were absent from `detect_capabilities`,
and nothing adds those entities dynamically, so one appearing after setup reached
the user only after a manual restart. They are carried as one token per device id
and per subject/path, which keeps the existing expansion-only reload trigger
correct on removal as well as on arrival.
Also folds in a deferred minor from the Task 5 review: `parse_number_format`
treats a reversed range or a non-positive step as unparseable, so a `NumberEntity`
is never built with bounds that admit no value or a step the frontend divides by.
Caveat: an existing `number.*` entity whose format reversed its bounds -- which
never worked -- moves to the sensor domain. Its unique_id is unchanged.

+message, so another device overflowing is news and a translation update is not; dismissal does not clear the record, because clearing it there is the defect.

**An id the registry already holds is never displaced.** The cap admits in adapter emission order, which tracks the wire, so a firmware update declaring a new
property earlier shifts everything after it. Capping on arrival order alone would let a new property evict a standing entity — whose registry row is permanent,
and for which nothing would ever build an entity again, leaving it unavailable forever with a stranger in its slot and no migration path by design. `adoptable`

Subject: [PATCH 181/345] fix(adoption): deterministic collision winner,
digested capability tokens
The adopted unique_id collision guard picked its survivor by adapter emission
order, which tracks the wire. A firmware update that declared the two colliding
properties in the other order would then have changed what a standing entity
reads -- silently, since the unique_id does not move and nothing here migrates
it. `_create` sorts each device's properties by wire path, so the survivor is a
function of the declarations alone. The test runs both declaration orders.
Registry preference, which is how the extension cap resolves its equivalent
problem, is not available here: both properties resolve to the same unique_id,
so the registry row cannot say which of them put it there.
The new capability tokens carried adopted device ids and extension instance keys
verbatim, and `_check_capability_change` logs the capability set at INFO whenever
it expands. `diagnostics.AdoptedDeviceRow` states the rule those tokens were
breaking: a device id can embed a serial, because producers derive a DER's id
preferring a serial over a default slug, which is why that block reports
`proxied` rather than `parent`. Both identity segments are now a truncated
sha256. The reload trigger only compares tokens for equality, so a stable digest
is the identity as far as it is concerned; the subject kind and wire path stay in
the clear because they are vendor vocabulary and name no install.
`additions._load` reported "found NoneType" for a record with no
`announced_unique_ids` key -- the type of what `get` returned rather than of
anything on disk, which reads as a null somebody wrote and sends the reader to
the wrong part of the file. `_describe` now says "missing" for an absent key,
names the offending element type for a bad list, and keeps NoneType only where
a null was written.
Also clears the three ruff errors that predate this branch in
tests/test_coordinator.py, which this task's diff touches: the import block it
edited (I001) and two nested `with` blocks (SIM117).

Subject: [PATCH 182/345] refactor: runtime-data types in a leaf module, one
guard, no casts
`SpanPanelRuntimeData` and `SpanPanelConfigEntry` lived in `__init__.py`,
which imports every platform. Naming the entry type therefore meant
importing the whole integration, so seven modules imported it from the
package root and five more reached for it from inside functions --
`services.py` had five copies of the same runtime-data guard, each behind
its own deferred import. pylint counted 21 cyclic-import chains, 10 of
them routed through the package root.
The two types now live in `runtime.py`, whose only runtime dependency
inside this package is `control_gate` (itself a leaf); the coordinator is
needed there as an annotation only. The package root re-exports both
names, so `from custom_components.span_panel import SpanPanelRuntimeData`
keeps working for the 22 test modules that use it. Every deferred import
of them is now a top-level one, and the five guards are one
`_loaded_runtime_data()` that still answers with `isinstance` (AGENTS.md
point 6) -- core deletes `runtime_data` on unload, so both halves of the
check are real. 21 cycles -> 16, root-routed 10 -> 3.
The nine `cast(ServiceResponse, ...)` in `services.py` go with them.
`ServiceResponse` is `dict[str, JsonValueType] | None`, and `dict` is
invariant, so the responses are built at that type instead of asserted
into it; the two that were only ever redundant are simply returned.
The tenth cast was `sensor_base.extra_restore_state_data` asserting a
`SpanEnergyExtraStoredData` into the `SensorExtraStoredData` that
`RestoreSensor` declares. It restated that class's two fields rather than
inheriting them; it now subclasses it and the assertion is unnecessary.
The stored keys are unchanged, so existing records restore identically.
`SpanPanelEntity.coordinator` is annotated explicitly. The generic base
binds correctly, but the attribute is only created by
`BaseCoordinatorEntity.__init__`'s unannotated `self.coordinator =
coordinator`; mypy does not run inference over installed packages, so it
read as `Any` and every `self.coordinator.X` in this integration was
unchecked. It resolves to `SpanPanelCoordinator` now, with no new casts
needed anywhere.

Subject: [PATCH 183/345] fix(coordinator): follow settability changes in both
directions
A circuit's controllability was watched by the switch and the select
themselves, each comparing the gating predicate against the answer it was
constructed with. That sees only half of it. A circuit the panel declares
non-commandable gets neither entity, so when the panel later commissions it
there is nothing on that circuit to notice: the switch and the select it has
earned appear at the next reload that happens for some other reason, or at the
next restart.
The reader that can see it is the one that reads the whole snapshot. This moves
the watch to `_check_settability_change` on the coordinator, beside
`_check_capability_change` and modelled on it: one pass over every circuit
answering both gating predicates, a baseline taken from the first snapshot, and
one reload requested on any change since -- gained or lost. The baseline moves
on the pass that asks, so a panel holding its new answer does not reload again
on every push. Only circuits present in both readings are judged: circuits drop
out of a snapshot and come back, which both platforms already guard for, and
reading an absence as a change would turn a flap into a reload loop.
The two predicates move to `helpers`, which is where the coordinator can read
them from -- `switch.py` and `select.py` import the coordinator, so the
predicate they share with it has to sit below all three. They stay single
copies, gating creation and the reload trigger on the same answer.
Also drops `async_create_span_notification`, dead since the select stopped
calling it, and pins `SpanPanelRuntimeData`'s default lock to the default
policy's `lock_enabled` so the two cannot drift apart.

Subject: [PATCH 184/345] docs: the security release, its limits, and two stale
pins
The 2.1.0 changelog described the release as it stood fourteen commits
ago. Every user-visible change from the review fixes now has one bullet
under the heading it belongs to, and the two bullets that had gone stale
are corrected rather than left standing.
Security gains what the pinning work actually did beyond the first pin: a
pinned entry never left holding an address its own certificate does not
name, "continue anyway" keeping the panel rather than the unregistered
domain, the deferred pin and the CA-changed repair both checking the
fetched authority against the certificate the broker serves before
storing it, and a discovered or re-added host moving a pinned entry only
when it chains to that entry's anchor. `rotate_credentials` gains its
three: naming the panel when more than one is loaded, reporting a reload
that did not come back, and refusing to travel unverified.
Two Security bullets were wrong rather than missing. The settability one
claimed one direction and "the next update"; it is both directions and a
reload the integration asks for. And `Administrators only` is now stated
not to cover an automation, which Home Assistant hands a fresh context
with no user on it -- the option for those callers is the contextless one
beside it.
Adoption's qualifications go under Added, because adoption ships in this
release and a fix to something nobody has run is not a fix: a number box
only where the declared range reads, the lexically first wire path
keeping a colliding id, a device arriving after setup reaching the user
on its own, the 60-per-device cap and its once-per-change notice, and the
announced-entities store re-seeding rather than failing setup. Fixed
gains the dip's post-corroboration window, the notification moving to
settling, and a dead transport making entities unavailable instead of
reading 0 W. `at_service_entrance` is stated as present only on the
parent/child data model.
A new Known issues section records the four things the release does not
close: a single-label name cannot complete a pinned install, an upgraded
entry whose broker port serves someone else's certificate stays unpinned
with no repair, a refused host move points at Reconfigure, and Supervisor
discovery is deliberately outside the address check.
README's Security section follows: reauth acquiring an anchor, how a
hostname install is verified, what moves a pinned entry and what does
not, the Supervisor exception, and rotation's three refusals. Its dip
section described a notification that now fires three readings later.
developer.md's settability section said nothing re-reads it, which stopped
being true at 86b0745 and 39491ff; it now describes the coordinator's
reader and why both edges live there. The adopted collision rule says
lexically first, `runtime.py` and `_loaded_runtime_data` are documented,
and the unguarded Supervisor path is written down where the next reader
of config_flow.py will find it. AGENTS.md point 6 names the helper
instead of the pattern.
pyproject was still on 2.1.0b6 against a b16 manifest, and prek pinned
ruff v0.15.1 against the v0.15.12 in the dependency group.

stored PEM skips the CA chooser at config_flow.py:1293 -- the leaf check

branch writes the host and reloads. What pins it is `_async_pinned_ca`

advertised by..." WARNING.
Reauthenticate is the route that does it on screen: an unpinned v2 entry
goes to `async_step_panel_ca_start`, which asks for the TLS port where
the HTTP port has been moved -- the proxy population this limitation is
about -- and refuses with an error where the authority does not sign what
the panel serves. Both places now say that, and say the reload is the
quiet alternative rather than the documented one.
Also, from the same review: the two dip bullets become one statement of
what ships, since a bullet describing what an earlier beta did is
beta-vs-beta narration; the reversed-range bullet drops its beta clause
for the same reason; and "Known issues" becomes "Known limitations",
which is what those four entries are.
uv.lock carries the version line the dependency sync wrote after the
pyproject bump in 152da89.

The comment above the deferred pin claimed the anchor is used for one thing.
It is used for two: the MQTTS session and, once stored, every REST call
`panel_rest_transport` builds — reauth detection, reconfigure, FQDN
registration and rotate_credentials, all on the HTTPS port. Rewrite it to say
which port is verified and why, and state the cost of verifying one port while
using the anchor on two: a proxy terminating only 443 pins at reload and then
fails every REST path. Say the same in README's Security section and in the
changelog's matching Known-limitations bullet.
Reconfigure took the default plaintext fallback, so an entry whose stored PEM
no longer parses was silently downgraded — `delete_fqdn` and `register_fqdn`
then carried the access token over HTTP and `_async_verify_host_over_pin`
returned early with nothing to verify against. It now fails closed the way
rotate_credentials does: `allow_plaintext_fallback=False`, a new `ca_unusable`
form error, and no REST call and no host write. Covered by a test using a
genuinely unloadable PEM.
Sweep:
- `8883` literals in config_flow become DEFAULT_MQTTS_PORT.
- `int(...)` on stored ports in `__init__` becomes `as_port`, which substitutes
the documented default instead of raising out of setup on garbage.
- The refused-host-move warning now says how to move the entry deliberately.
- `async_step_hassio` carries a comment marking it the deliberately unguarded
Supervisor path, mirroring developer.md.
- `_check_settability_change` records the partial-retained-replay false
positive: one spurious reload per library client rebuild, a 3.1.1 item.
- `_pinned_fingerprint` and `repairs._fingerprint_or_reason` were the same
function; they become `pem_fingerprint_or_reason` in config_flow_validation.
- The two inline `hasattr(entry, "runtime_data")` pairs in the package root
call the shared guard, which moves from `services` to `runtime` — a leaf that
already owns the type, where `services` is inside an existing import cycle.
- `_mark_transport_dead` logs at WARNING; the library and the CA-changed repair
already report the same condition at ERROR.
- The control-lock switch stays available on a dead transport. Arming is local,
and core skips an unavailable entity in `switch.turn_on`, so inheriting the
base class's transport probe left the lock unshuttable at the moment someone
would most want it shut.

Subject: [PATCH 187/345] chore: 2.1.0b17
Carries the fixes from the 2.1.0 release review: CA pinning on reauth and
FQDN installs, a control lock that survives reload, one outcome path for
every control, the dead-transport availability fix, dip retraction after
corroboration, and the naming route that lets Home Assistant compose
circuit entity ids from the user's own settings.

+# Entity IDs and Names — the rules
+
+This document is the permanent statement of how this integration names entities and composes their entity IDs. It exists because the question has been
+re-derived from scratch more than once. The rules below are the maintainer's intent; they outrank any single design document, review note or older comment. A
+change to naming is checked against them first, and a change that cannot satisfy them is not made.
+
+Every claim here is grounded in the code as of 2.1.0 (`naming.py`, `entity.py`, `sensor_base.py`, `sensor_circuit.py`, `switch.py`, `select.py`) and in Home
+Assistant Core 2026.8 (`helpers/entity_registry.py`, `helpers/entity_platform.py`). When the code and this document disagree, one of them is wrong — fix it, do
+not paper over it.
+
+## 1. The five rules
+
+| # | Rule |
+| ------ | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
+| **R1** | **Recreate never offers an uncaused rename.** The base this integration supplies must reproduce an existing entity's ID when Home Assistant composes it under the entity-ID options matching how that install was built. Our own doing — two suffix spellings, a reworded label, a registry `name` an older release wrote — never produces an offer. An offer that reflects the user's own configuration (an area they assigned, a device they renamed, a circuit they renamed on the panel, `entity_id_parts` they chose) is legitimate. |
+| **R2** | **The integration supplies only the flag-driven base.** `Circuit 15 power` or `Kitchen Outlets power`. Device and area prefixes are Core's, by the user's global `entity_id_parts` choice, and this integration does not exempt itself from that choice. No `entity_id` is preset, ever. |
+| **R3** | **Circuit-numbers mode promises the circuit-number token stays stable across circuit renames** — not the surrounding prefix text, which is Core's. |
+| **R4** | **The display name is the panel's, delivered as `original_name`.** The registry `name` field is the user's and is never written by this integration. The one write it makes to that field is to _clear_ a value a pre-2.1.0 release wrote there (§6). |
+| **R5** | **Existing entity IDs never move.** Nothing moves an ID without the user pressing **Recreate entity IDs** and accepting the offer. Unique IDs never change with the naming style. |
+
+A consequence worth stating outright: R1 does **not** mean bypassing `entity_id_parts` with a hard-coded ID. Where composition yields a different device or area
+part than the entity has today, that is the user's configuration at work and the offer stands. The one-time attempt to add "legacy preset" exceptions for those
+cases was withdrawn.
+
+## 2. Three fields, three owners
+
+Every entity has three naming-relevant values. Keeping them apart is the whole design.
+
+| Value | Owner | What it is | Where it lives |
+| ------------------- | --------------- | ----------------------------------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------- |
+| **Display name** | The panel | `"{circuit name} {label}"` — `Kitchen Outlets Power`, `Bathroom Lights Breaker` | `_attr_name` → registry `original_name`. Same string in both naming modes. |
+| **Object-ID base** | The naming flag | `"{identifier} {suffix words}"` — `Kitchen Outlets power` or `Circuit 15 power` | `SpanPanelEntity._span_object_id_base` → `suggested_object_id` property → registry `object_id_base`. |
+| **Registry `name`** | The user | Whatever they typed in the entity's settings. Outranks everything in both display and ID composition. | Registry `name`. Read to detect an override; never written (except the §6 release). |
+
+The display name and the base are decoupled **on purpose**: a label can be reworded without touching a single ID, and an ID can carry an old spelling while the
+label is current.
+
+## 3. How Home Assistant composes an ID (Core 2026.8)
+
+This is Core's behaviour, cited so nobody has to re-read Core to trust the rest of the document.
+
+### 3.1 Priority
+
+`EntityRegistry._async_generate_entity_id` (`helpers/entity_registry.py`):
+
+```text
+name > suggested_object_id > object_id_base
+```
+
+- `name` (the user's registry name) — always prefixed with the device name.
+- `suggested_object_id` — used **verbatim, not prefixed** with device or area. This is where a preset `entity_id` lands.
+- `object_id_base` — prefixed with device (and area, if the user's settings include it) when `has_entity_name` is True. All of ours have it True.
+
+The prefixing follows `self.settings.entity_id_parts`, defaulting to `(AREA, DEVICE, ENTITY)`. Device name is `device.name_by_user or device.name`; the area is
+the entity's, falling back to the device's.
+
+### 3.2 What the platform hands Core
+
+`entity_platform._async_derive_object_ids`:
+
+- If the entity preset `entity_id` (`internal_integration_suggested_object_id`), that becomes `suggested_object_id`. **We never do this.**
+- Otherwise `entity.suggested_object_id` becomes `object_id_base`. The stock property returns the display name; ours returns the base (§4).
+
+### 3.3 The stored row is refreshed on every add
+
+`async_get_or_create` on an entity that already exists calls `_async_update_entity(..., object_id_base=..., suggested_object_id=...)`, and the update applies
+any value that is not `UNDEFINED` and differs from the stored one — **including `None`**. So every reload rewrites the row's `object_id_base` from the current
+base and clears a stale `suggested_object_id`. The row is never frozen at creation.
+
+### 3.4 Recreate entity IDs regenerates from the stored row
+
+`async_regenerate_entity_id(entry)` composes from `entry.name`, `entry.suggested_object_id`, `entry.object_id_base`, `entry.device_id`, `entry.area_id` — the
+**stored row**, not the live entity. Two corollaries:
+
+- A row whose `suggested_object_id` still holds a 2.0.8 preset reproduces that preset forever, whatever the entity now wants. That is exactly why 2.0.8 could
+ not follow a rename (#252), and why a 2.0.8 install that _appears_ to run 2.1.0 but has not actually loaded it shows "No renamable entity IDs".
+- A row whose `name` is set composes from that, device-prefixed, in both display and ID. That is why a 2.0.8 circuit-numbers install got friendly-name offers
+ (§6).
+
+## 4. What this integration does — one path, both modes
+
+### 4.1 The identifier (the naming flag's half)
+
+`sensor_circuit._resolve_circuit_identifier`, and the same branch inline in `switch.py` / `select.py`:
+
+| Mode | Identifier | Source |
+| --------------------------------------- | --------------------------------------------------------- | --------------------------------------------------------------------------------- |
+| Circuit numbers (`use_circuit_numbers`) | `Circuit 15`, `Circuit 30 32` (every tab, sorted) | `helpers.construct_circuit_identifier_from_tabs(circuit.tabs, circuit_id)` |
+| Friendly names, circuit has a name | the panel's name, verbatim | `circuit.name` |
+| Friendly names, circuit unnamed | `Solar` (PV), `EV Charger` (EVSE), else `Circuit 7` (tab) | `_unnamed_circuit_fallback` — never `None`, so two unnamed circuits never collide |
+| Unmapped tab (either mode) | `Unmapped Tab 32` | `SpanUnmappedCircuitSensor._object_id_parts` |
+
+The identifier **always answers**. A `None` identifier lets Core compose from the label alone, which gives every unnamed circuit the same ID and leaves the
+registry to disambiguate with `_2`, `_3` — the pre-2.1.0 behaviour that is now gone.
+
+### 4.2 The suffix
+
+Each entity names its canonical suffix:
+
+- Circuit sensors: `id_builder.get_user_friendly_suffix(description key)` → `power`, `energy_consumed`, `energy_produced`, `energy_net`, `current`,
+ `breaker_rating`.
+- Switch: `"breaker"`, named outright (`get_user_friendly_suffix` has no switch entry).
+- Select: the description key `"circuit_priority"`, verbatim (`get_user_friendly_suffix` would map it to `priority`, which is the unique-ID's spelling, not the
+ entity-ID's).
+
+`CIRCUIT_SUFFIX_MAPPING` in `id_builder` builds **unique IDs** and is closed. The tables in `naming.py` govern **entity IDs only**. Do not cross them.
+
+### 4.3 The base — `naming.circuit_object_id_base(identifier, suffix, existing_entity_id)`
+
+Returns `"{identifier} {suffix words}"`, where the words are decided in this order:
+
+1. **The existing ID still names this circuit** (`..._{identifier_slug}_{form}` or `..._{identifier_slug}`): what follows the identifier settles both the form
+ the ID carries and whether the preset builder omitted the suffix. They are one question, answered together — answering them separately produced
+ `..._current_current_power` for a circuit named "Current" and `..._solar_power` for one named "Solar Power", both uncaused renames (R1).
+2. **The existing ID no longer names this circuit** (renamed on the panel, #252): the form is read back from the _end_ of the ID by itself
+ (`_existing_suffix_form`), and the omission is decided from the _new_ name. The name half follows the panel; the suffix half does not.
+3. **No existing ID**: the noun-last wording from `NEW_ENTITY_ID_SUFFIX_WORDS` (`consumed energy`, matching the panel-level `main_meter_consumed_energy`).
+
+`ENTITY_ID_SUFFIX_FORMS` lists every suffix form ever shipped (`consumed_energy` before the preset era, `energy_consumed` after; `current_power` and `power`).
+**An entry is added only when another form is discovered to have shipped, never to introduce one.** An existing entity is offered whichever spelling it already
+carries and never the other (R1).
+
+Worked examples (friendly mode, `(DEVICE, ENTITY)` parts, device "Span Panel"):
+
+| Circuit name (panel) | Existing ID | Suffix | Base | Composed / offered |
+| ----------------------- | --------------------------------------------------- | ----------------- | --------------------------------- | --------------------------------------------------------------- |
+| Kitchen Outlets | none | `energy_consumed` | `Kitchen Outlets consumed energy` | `sensor.span_panel_kitchen_outlets_consumed_energy` |
+| Kitchen Outlets | `sensor.span_panel_kitchen_outlets_energy_consumed` | `energy_consumed` | `Kitchen Outlets energy consumed` | its own ID — no offer |
+| Bathroom Lights Renamed | `switch.span_panel_bathroom_lights_breaker` | `breaker` | `Bathroom Lights Renamed breaker` | `switch.span_panel_bathroom_lights_renamed_breaker` |
+| Solar Power | `sensor.span_panel_solar_power_power` | `power` | `Solar Power power` | its own ID |
+| Solar Power | `sensor.span_panel_solar_power` | `power` | `Solar Power` | its own ID |
+| Power | `sensor.span_panel_power_power` | `power` | `Power power` | its own ID (a name that _is_ the suffix word keeps both halves) |
+
+Circuit-numbers mode is the same table with `Circuit 15` in the identifier column — and a rename on the panel changes nothing in it (R3).
+
+### 4.4 Delivery to Core
+
+`SpanPanelEntity` (`entity.py`) carries `_span_object_id_base: str | None = None` and overrides the `suggested_object_id` property to return it when set, or
+`super().suggested_object_id` (the display name) when not. Core's `type.__getattribute__` guard covers the `name` property only, so this override is supported.
+Circuit sensors, the switch and the select set the base at construction. Every other entity leaves it `None` and composes from its label as it always has.
+
+`entity_id` is **never** preset. Nothing in this integration assigns `self.entity_id` or `_attr_entity_id`.
+
+### 4.5 Who composes without a base
+
+- **Sub-device circuit sensors** (an EVSE feed circuit's sensors, `_is_sub_device`): no base. Core composes from the label on the charger's device, so the ID
+ names the charger alone — `sensor._power` — like the charger's other sensors. A feed sensor created before this route keeps its old ID until Recreate
+ is pressed, and is then offered the charger-named one (a legitimate offer: the device part is Core's).
+- **Everything not a circuit entity** (panel, BESS, MID, EVSE, PV, binary sensors, adopted properties): stock behaviour, label-composed.
+
+### 4.6 Legacy `use_device_prefix`
+
+Stored, preserved by the options flow, and read by `get_current_naming_pattern`, but it **cannot keep the device out of a composed ID** — Core includes the
+device unless the user's own `entity_id_parts` excludes it. An install predating the option, whose circuit IDs carry no device half, is offered one on Recreate.
+That is Core composing under the user's settings, and it is documented in the README and CHANGELOG rather than special-cased.
+
+## 5. Name sync — what "phase 1" and "phase 2" mean, and what they mean now
+
+The terms come from the pre-2.1.0 design and are still used in conversation, so here is what each was and what it is today.
+
+### 5.1 Before 2.1.0 (the two-phase scheme, for context only)
+
+- **Phase 1 — construction.** `_attr_name` was set from the _naming flag_ (`Circuit 15 Power` in circuit-numbers mode) so that Core would derive a flag-shaped
+ `object_id_base`, and `entity_id` was **preset** by a builder, which Core stored as `suggested_object_id`. A new entity displayed the flag name until phase 2.
+- **Phase 2 — first coordinator update, and every rename after.** Circuit-numbers mode **wrote the registry `name`** with the panel's name to fix the display.
+ That put the panel name in the user's field, which outranks everything in ID generation — so Recreate proposed a friendly-name ID for every circuit-numbered
+ entity, and a rename in the SPAN app could never reach the preset `suggested_object_id` (#252). Friendly mode's phase 2 was idempotent (same string) and wrote
+ nothing.
+
+### 5.2 In 2.1.0 the phases collapse to one
+
+There is one name path, in both modes:
+
+1. **Construction** (`sensor_base.py`, `switch.py`, `select.py`): `_attr_name = "{circuit name} {label}"` — the _panel's_ name, unconditionally, existing entity
+ or not. It reaches the registry as `original_name`. The base (§4.3) is computed at the same time and handed to Core through `suggested_object_id`. If an
+ existing row carries a `name` a pre-2.1.0 release wrote, it is released (§6).
+2. **Every coordinator update** (`_handle_coordinator_update` / `_sync_circuit_name`): the entity compares the panel's current circuit name with the one it was
+ built from.
+ - If the registry `name` is set, the user has overridden the name: the panel's rename is **noted and ignored** — theirs outranks it, and a reload would
+ change nothing on screen.
+ - If the entity was **not** in the registry at construction (`_previous_circuit_name is _NAME_UNSET`), the first update requests one reload. This is the
+ surviving trace of "phase 2": a freshly created entity's registry row is settled by that reload.
+ - If the name **changed**, the entity requests a reload (`coordinator.request_reload()`).
+3. **Reload** (`coordinator.py`, end of the update cycle): the entry is torn down and rebuilt. `original_name` is only written when an entity is added, so a
+ rebuild is the only way to refresh it — that is why a rename costs a reload rather than a registry write. The rebuild also recomputes the base with the new
+ circuit name and, per §3.3, rewrites the row's `object_id_base`.
+
+The rename therefore reaches:
+
+| What | Friendly names | Circuit numbers |
+| ------------------------- | ------------------------------------------------- | --------------------------------------------------------------------------------------------------- |
+| Display name | new name, after the reload | new name, after the reload (`Span Panel Kitchen Outlets Power`, device-prefixed like friendly mode) |
+| Entity ID | unchanged (R5) | unchanged (R5) |
+| Row `object_id_base` | `Kitchen Outlets Renamed power` | `Circuit 15 power` — unchanged |
+| Recreate entity IDs offer | `sensor.span_panel_kitchen_outlets_renamed_power` | its own ID — no offer (R3) |
+| Registry `name` | untouched | untouched |
+
+Settability changes (a circuit becoming or ceasing to be controllable) are **not** watched here; `SpanPanelCoordinator._check_settability_change` does that,
+because the "gains a control" edge happens on circuits that have no entity to see it.
+
+## 6. Releasing the registry `name` a pre-2.1.0 release wrote
+
+`naming.release_registry_name_written_by_older_release(registry, entity_id, circuit_name, description_names)` runs once per existing circuit entity at
+construction. It clears the registry `name` **only** if it equals `"{circuit_name} {label}"` for the description's current label _or any label it has carried
+before_ (`SpanPanelCircuitsSensorEntityDescription.legacy_names`: `Energy Consumed` / `Energy Produced` / `Energy Net` beside the current `Consumed Energy`
+etc.). Any other value is the user's and is left exactly where it is. The switch releases `"{name} Breaker"`, the select `"{name} {description name}"`.
+
+This is the one write this integration ever makes to the user's field, and it is a hand-back, not a claim. Miss a release site and that platform's Recreate
+stays poisoned: under composition a stale `name` composes _with the area_, so a 2.0.8 name on a panel in "Basement" would propose
+`sensor.basement_span_panel_kitchen_outlets_consumed_energy`.
+
+## 7. Offers that are legitimate — and the one that is not fully avoidable
+
+Recreate offers a different ID only where the user's own configuration composes one. Each of these is documented for users in README and CHANGELOG:
+
+| Situation | Offer | Cause |
+| ---------------------------------------------------------------------------- | --------------------- | ------------------------------------------------------------------------------------------------- |
+| Circuit renamed on the panel, friendly mode | the new name's ID | user renamed it |
+| Panel device in an area, `entity_id_parts` includes AREA (the default) | area-prefixed ID | user assigned the area |
+| Panel device renamed by the user (`name_by_user`) | ID carrying that name | user renamed the device |
+| Sensor on a SPAN Drive feed circuit | charger-named ID | device part is Core's |
+| Second panel whose generated device name is "Span Panel 2" | `span_panel_2_…` | device part is Core's |
+| Install predating `use_device_prefix`, circuit IDs with no device half | device-prefixed ID | device part is Core's |
+| Unnamed circuit in friendly mode whose ID carries `single_circuit`/`power_2` | `circuit_7…` | **the one uncaused offer** — no computed identifier reproduces both eras; accepted and documented |
+
+Anything not in this table that Recreate offers on an unchanged install is a bug against R1.
+
+## 8. Things that must stay true (checklist for any change touching naming)
+
+- [ ] No entity presets `entity_id`. `Grep` for `entity_id =` and `_attr_entity_id` in platform code finds nothing.
+- [ ] The registry `name` is never assigned a value; the only `async_update_entity(..., name=...)` call is the `None` in
+ `release_registry_name_written_by_older_release`.
+- [ ] `_attr_name` is the panel's name in both modes; nothing branches on `use_circuit_numbers` to pick a display name.
+- [ ] The base is computed from `(identifier, canonical suffix, existing_entity_id)` and nothing else — never from the display label.
+- [ ] `ENTITY_ID_SUFFIX_FORMS` gains an entry only for a form found to have shipped; `NEW_ENTITY_ID_SUFFIX_WORDS` and it stay in one-to-one correspondence
+ (`test_every_form_table_entry_has_a_new_wording_and_vice_versa`).
+- [ ] A reworded description label adds the old label to `legacy_names` so §6 still recognises what 2.0.8 wrote.
+- [ ] Unique IDs are untouched by any of this; `CIRCUIT_SUFFIX_MAPPING` is closed.
+- [ ] `tests/test_naming.py` and `tests/test_recreate_entity_ids.py` pass. The latter drives a real `EntityPlatform` with `entity_id_parts` fixed, so a
+ composition regression fails there rather than in a unit test of a builder.
+- [ ] Run the `entity-id-auditor` agent after editing `id_builder.py`, `entity_resolver.py`, `naming.py` or any circuit platform file.
+
+## 9. Diagnosing "Recreate offered nothing" on a live install
+
+1. Confirm the running code: `manifest.json` version and the presence of `custom_components/span_panel/naming.py`. A 2.0.8 install with 2.1.0 selected in HACS
+ but not yet loaded shows exactly this symptom, because its rows still hold the 2.0.8 preset in `suggested_object_id` (§3.4).
+2. Read the entity's row in `.storage/core.entity_registry`: on 2.1.0 after at least one reload, `suggested_object_id` is `null` and `object_id_base` reads the
+ base (`Bathroom Lights Renamed breaker`). A non-null `suggested_object_id` means the entity has not been re-added by 2.1.0 code.
+3. Check `name` on the row: a non-null value is a user override (or an unreleased 2.0.8 write — compare against §6's patterns) and outranks the base.
+4. Confirm the rename-triggered reload happened: the log carries `Auto-sync detected circuit name change from '…' to '…'` followed by the entry reload.
+5. Only then look at `circuit_object_id_base` with the row's exact `entity_id`, identifier and suffix — `tests/test_naming.py` shows how to call it directly.
+
+## 10. Where the history lives
+
+The design trail (issue #252 write-up, the 2026-08-22 spec and plan, the 2026-08-26 composition-route review) lives in the `SpanPanel_Docs` workspace, not in
+this repository. It records how the rules were arrived at and the routes that were rejected. It is history; this document is the rule.

Subject: [PATCH 190/345] chore(tests): drop two empty test modules and the
README documenting one
test_coordinator_migration.py and test_entity_bulk_naming_patterns.py were
both zero bytes. entity_id_renaming_README.md documented the second one in
full -- every class it names (TestYamlFixtureValidation,
TestBulkEntityIdNamingPatterns, TestBulkModificationEdgeCases) and every
fixture it points at are gone, and nothing links to it, so it goes with them
rather than leaving a doc describing a suite that no longer exists.

-# Bulk Entity ID Naming Pattern Tests Summary
-
-## Overview
-
-This test suite validates bulk entity ID naming pattern changes with user customization preservation. It demonstrates how the integration handles system-wide
-transformations while preserving all user modifications.
-
-## Test Structure
-
-### 1. YAML Fixture Validation (`TestYamlFixtureValidation`)
-
-- **`test_all_yaml_fixtures_are_valid`**: Validates all YAML fixtures have proper structure and required fields
-- **`test_fixture_naming_patterns_are_consistent`**: Ensures naming patterns follow expected conventions across fixtures
-- **`test_fixture_user_customizations_are_preserved`**: Verifies user customizations are identical across before/after fixtures
-
-### 2. Bulk Naming Pattern Tests (`TestBulkEntityIdNamingPatterns`)
-
-- **`test_crud_then_bulk_naming_pattern_change_preserves_customizations`**: Main workflow test demonstrating CRUD operations followed by bulk naming changes
-- **`test_naming_pattern_combinations`**: Tests all four naming pattern combinations (device prefix + circuit numbers)
-
-### 3. Edge Case Tests (`TestBulkModificationEdgeCases`)
-
-- **`test_empty_sensor_set_handling`**: Validates graceful handling of empty sensor sets
-- **`test_unknown_sensor_types_preserved`**: Ensures unknown sensor types are preserved during bulk modifications
-
-## YAML Fixtures
-
-### `/tests/fixtures/circuit_numbers.yaml`
-
-### `/tests/fixtures/device_prefix.yaml`
-
-### `/tests/fixtures/device_prefix.yaml`
-
-Demonstrates solar sensors with friendly naming pattern:
-
-- `entity_id: "sensor.span_panel_solar_inverter_power"`
-- `entity_id: "sensor.span_panel_solar_inverter_energy_produced"`
-- Contains user customizations (custom attributes, modified names)
-
-### `/tests/fixtures/solar_sensors_circuit_numbers.yaml`
-
-Shows the same sensors with circuit number naming pattern:
-
-- `entity_id: "sensor.span_panel_circuit_30_32_power"`
-- `entity_id: "sensor.span_panel_circuit_30_32_energy_produced"`
-- **All user customizations preserved** - only entity_ids change
-
-## Key Testing Principles
-
-1. **Real YAML Fixtures**: Tests use actual YAML files instead of embedded strings
-2. **Fixture Validation**: Dedicated tests ensure all fixtures are valid and consistent
-3. **User Customization Preservation**: Validates that bulk operations preserve all user modifications
-4. **Pattern Consistency**: Tests verify naming patterns follow expected conventions
-5. **Edge Case Coverage**: Handles empty sets and unknown sensor types
-
-## Test Benefits
-
-- **Comprehensive Validation**: All fixtures are validated together
-- **Real-world Scenarios**: Tests actual YAML structures users would create
-- **Pattern Verification**: Ensures naming patterns are consistent and predictable
-- **Customization Safety**: Proves user modifications survive bulk changes
-- **Maintainability**: Easy to add new fixtures and validate them automatically
-
-This test suite provides confidence that bulk entity ID naming pattern changes work correctly while preserving all user customizations.

Subject: [PATCH 191/345] refactor(evse): one empty-charger sentinel, in util
beside the builder that reads it
binary_sensor, number and sensor_evse each defined an identical
SpanEvseSnapshot(node_id="", feed_circuit_id="") as the fallback for
snapshot.evse.get(). The value is shared, so the definition is too: EMPTY_EVSE
now lives in util.py next to evse_device_info, the builder every one of those
call sites feeds it into.
Safe as a single module-level instance because SpanEvseSnapshot is frozen.

Subject: [PATCH 192/345] refactor(binary_sensor): name the offline-visible
sensor set once
available() and _handle_coordinator_update() each built the same three-element
set inline. They have to agree -- a sensor added to one and not the other would
report unknown while offline but drop out of availability, or the reverse -- so
the set is now a module-level frozenset both read, following
_EV_CONNECTED_STATUSES.

Subject: [PATCH 193/345] refactor(controls): drop the client capability checks
that cannot fail
coordinator.client is typed SpanMqttClient, which defines set_circuit_relay,
set_circuit_priority, set_dominant_power_source and set_evse_charge_limit, so
every guard in front of them was statically unreachable:
- switch.async_turn_on/off, select.async_select_option and button.async_press
each did hasattr() and logged "Client does not support ..." before returning.
- number.async_set_native_value did isinstance(client, EvseControlProtocol) and
raised evse_charge_limit_unsupported. SpanMqttClient satisfies that protocol
structurally, so the error was unreachable; its strings.json entry and the
five locale copies go with it.
- button.async_setup_entry gated the override on
isinstance(coordinator.client, SpanMqttClient), which is the declared type.
Only the has_bess() half of that condition ever decided anything.
The single pattern is now no runtime check at all -- the type is the guarantee.
EvseControlProtocol stays as the set_fn parameter type, which is what keeps the
description free of a transport class.
Tests that only drove the removed branches are gone; the button setup test keeps
its has_bess coverage without the isinstance scaffolding.

Subject: [PATCH 194/345] refactor(diagnostics): read device_type and tabs
straight off the circuit
SpanCircuitSnapshot is frozen and declares both fields -- tabs is required,
device_type defaults to "circuit" -- so the hasattr() guards could never be
false against a real snapshot. Both keys move into the dict literal with the
rest of the circuit's fields.
The one thing the guards did serve was a test that built its circuit as a
SimpleNamespace omitting those two fields. That double now uses
SpanCircuitSnapshotFactory, like the test beside it already did, so it cannot
drift from the model again.

actually takes; freeze the unit map
prominence_hint's third rank named node_has_curated_siblings, in both the
docstring and developer.md. No such function exists and nothing is recorded --
the branch is a plain fall-through to detail, and the node a property hangs off
is deliberately never consulted. Both places now say that.
DEVICE_CLASS_BY_UNIT was a bare dict, so a lookup table two modules read could
be mutated by either. It is now Mapping + MappingProxyType, matching
RESIDUAL_EXEMPT_PATHS in field_paths.py and _PANEL_BINARY_SENSOR_CLASSES in
binary_sensor.py.

Subject: [PATCH 197/345] refactor(sensor_circuit): one circuit-sensor base,
one API key map
SpanCircuitPowerSensor and SpanCircuitEnergySensor restated the same identity
logic: a byte-identical __init__ description-copy block, a _generate_unique_id
and an _object_id_parts differing only in which _API_KEY_MAP they read, and an
identical get_data_source.
The two maps were never duplicates -- their key sets are disjoint, and sensor.py
hands each class only its own three keys -- so they collapse into one
module-level MappingProxyType that neither can shadow.
The rest moves to SpanCircuitSensorBase, which the power sensor extends directly
and the energy sensor mixes with SpanEnergySensorBase. Cooperative super() keeps
the grace-period init, _process_raw_value and extra_state_attributes reaching
the energy base as before. Each subclass now holds only what genuinely differs:
its residual field paths, its displayed name, and its state attributes.
The description copy is now dataclasses.replace. The hand-written field list had
already drifted -- the energy class omitted entity_category -- and only
circuit_breaker_rating sets one, which is a power-sensor key, so no entity
changes. Verified field-by-field against all five circuit descriptions.
_ENERGY_TYPE_MAP is frozen the same way while here.
No unique id, entity id, name or object-id base changes: test_naming.py,
test_recreate_entity_ids.py and test_unique_id_generation.py pass unchanged.

Subject: [PATCH 198/345] refactor: remove the remaining guards that cannot
fail
Same class as the control-capability checks, in five more places:
- coordinator._run_schema_validation gated field_metadata on
isinstance(self._client, SpanPanelClientProtocol). _client is SpanMqttClient,
which carries all three protocol members, so the None arm was unreachable --
though field_metadata itself still returns None during a rebuild, so the check
below it stays. The docstring no longer claims a protocol read that is gone.
- binary_sensor tested hasattr(self.entity_description, "key") four times.
key is a required field on EntityDescription.
- getattr(self.coordinator, "panel_offline", False) in binary_sensor, button,
select, switch and sensor_base. SpanPanelEntity annotates
coordinator: SpanPanelCoordinator, which declares the property.
- sensor_base.available wrapped that getattr in try/except AttributeError plus
a bare except. panel_offline returns a bool field and cannot raise, so the
whole block collapses to the read.
- sensor_circuit._unnamed_circuit_fallback read device_type through getattr with
a "circuit" default, which is the field's own declared default.
No test drove any of the removed branches.

charge-limit write fails
The charger placeholder carried self._evse_id -- the serial-harmonised snapshot
key, which is neither the node id the wire addresses nor anything shown on a
dashboard. Both failure messages reach a person, so both now carry the name on
the charger's device card.
evse_device_info built that name inline. It moves to util.evse_display_name,
which the builder now calls, so the card and any message about the charger
cannot drift apart.
Also sorts the imports in the touched test file (pre-existing ruff I001;
tests/ is outside the ruff hooks).

Subject: [PATCH 201/345] perf(config_flow): fetch the CA once per FQDN
readiness wait, not once per poll
An entry that pins no CA had check_fqdn_tls_ready fetch one over plain HTTP
whenever ca_pem was None -- so the thirty-poll wait made thirty plaintext trust
decisions two seconds apart, each against whatever answered.
Acquiring an anchor and testing a leaf against one are different jobs on
different schedules: the leaf changes while the panel regenerates it, the anchor
does not, and only the caller knows it is polling. The fetch moves out to
async_download_ca_or_none and check_fqdn_tls_ready now requires an anchor, which
also removes its unreachable None arm. The wait holds the first successful fetch
for the rest of the run, and still retries if the panel is not answering yet.
The two reconfigure tests patched the old seam and now patch the new one; the
four direct tests split along the same line.

Subject: [PATCH 204/345] chore: pin span-panel-api-schema-1 1.1.1
The vendored schema-1 capture is byte-identical between 1.1.0 and 1.1.1;
only its provenance record moves. tests/fixtures/README.md's source path
for it named the package directory the capture left in 48b64a4.

-## The vendored adapter captures
-
-`tests/fixtures/schema_one_tree.json` and `tests/fixtures/schema_zero_types.json` are byte copies of payloads that live in `span-panel-api`. Committing them is
-what keeps this suite free of a cross-repo dependency: the tests run with no sibling checkout, and no runtime wheel has to keep shipping test data.
-
-### Refreshing the parent/child capture
-
-```bash
-# SPAN_PANEL_API_DIR names the checkout; see .env.example
-uv run python scripts/refresh-vendored-capture.py
-```
-
-The script copies the capture byte for byte and writes the release it came from into `tests/fixtures/schema_one_tree.source`, in one action. **That is the
-reason it exists.** Those two facts — the bytes, and the claim about which release they are — were previously updated by two different actions, so doing one and
-not the other was a single missed keystroke; doing both from one command makes them incapable of disagreeing.
-
-It refuses more than it accepts, deliberately. No `SPAN_PANEL_API_DIR`, a path that does not resolve, a directory that is not a checkout, a checkout whose
-schema-1 release is not the one installed, a checkout that has the file at neither known location, or a checkout that is not standing on the release's tag — all
-of these stop before anything is written. The last one matters most: the refresh that went wrong copied from a worktree that _declared_ the installed release
-while sitting on unreleased work behind `main`, so the declaration and the pin agreed while the bytes were a release old. A version in a working tree is intent;
-a tag is a fact. Copying from unreleased work is still possible with `--allow-unreleased`, because it is occasionally correct — it is how the capture was
-corrected while the fix was only on `main` — but it has to be said out loud rather than warned about and ignored.
-
-Commit both files together. They are one fact in two files.
-
-### Which guard tells you to run it
-
-| Guard | Compares | Catches | Needs a checkout |
-| ----------------------------------------------------------- | ----------------------------------------------------------- | ------------------------------------------------------------------------------------ | ---------------- |
-| `test_the_vendored_capture_matches_the_installed_adapter` | `schema_one_tree.source` against the installed distribution | a pin that moved while the copy stayed put | no |
-| `test_the_vendored_capture_is_byte_identical_to_its_source` | the capture against the copy in that release | a copy refreshed **wrongly** — reformatted, edited, or taken from the wrong checkout | yes |
-
-The first fails everywhere, including CI, the moment `manifest.json` moves and nobody refreshes. The second needs `SPAN_PANEL_API_DIR`, so it **skips** locally
-when no checkout is configured or the configured one is on another release, and **fails** under `CI`, where the workflow clones `span-panel-api` at the release
-the pin names. That asymmetry is deliberate and should not be "fixed": `span-panel-api` paid for it and records the reason in its `DEVELOPMENT.md`, under "A
-skip here is not a pass" — _"A skip reads in a summary line exactly like a pass, and that is how a stale vendored capture went unnoticed for nine days."_
-
-Either failure names the refresh. Run the script.
+## The adapter reference payloads
-### Why the capture is not copied at test time
+The conformance tests replay two real schema-adapter inputs: a full parent/child device tree and a flat `GET /api/v2/homie/schema` response. Neither is
+committed here. Both are package data of the adapter distributions — `span_panel_api_schema_1/reference/parent_child_tree.json` and
+`span_panel_api_schema_0/reference/homie_schema.json` — and `tests/adapter_fixtures.py` reads them through `importlib.resources`, exactly as the library's own
+suite does.
-Someone will eventually propose having the suite copy the fixture from `SPAN_PANEL_API_DIR` on every run, so it can never be stale. It would undo both things
-vendoring bought.
+So the payload the suite replays is whichever one the pinned wheel ships, and the pin in `custom_components/span_panel/manifest.json` is the record of which
+that is. **Moving to a newer capture is a pin bump and nothing else**: bump the adapter version there, let `scripts/sync-dependencies.py` carry it into
+`pyproject.toml` and `requirements_test.txt`, then `uv sync`. There is no copy to refresh and nothing to keep honest — a claim about which release the bytes
+came from cannot disagree with the bytes when the bytes are the release's.
-It puts the cross-repo dependency back — every test run needing a `span-panel-api` checkout, which is exactly what committing the bytes removed. And it makes
-the byte comparison vacuous: a copy compared against the thing it was just copied from can only ever pass. **Committed bytes that are allowed to disagree with
-their source are the whole mechanism.** That freedom to disagree is what let the comparison find a capture vendored from a stale path override, which nothing
-else in either repository could see. A fixture that silently re-syncs itself cannot report anything.
+`tests/test_library_resolution.py` is what makes the pin mean something: it checks that the `span_panel_api` actually imported is the one the pins name, rather
+than a worktree an override is pointing at.

-
-`tests/fixtures/schema_one_tree.json` is a byte copy of a payload that lives in
-`span-panel-api`, and `tests/fixtures/schema_one_tree.source` records which
-release it was copied from. Two files, two facts, and **that is the whole reason
-this script exists**: until now they were updated by two different actions -- a
-copy and an edit -- so doing one and not the other was a single missed keystroke,
-and the result was a capture whose claim about itself was wrong. Performing both
-from one command makes them incapable of disagreeing, which is a stronger
-guarantee than any amount of care with a two-step README.
-
-It is not hypothetical. The capture was once refreshed from a checkout that sat
-behind the recorded release, producing a copy that was faithful to *a* release
-and mislabelled as another; it recorded a producer defect that upstream had
-already fixed, and every conformance test kept passing against it. So this script
-refuses to copy from a checkout whose schema-1 release is not the one installed,
-and refuses again unless that checkout is standing on the release's *tag* --
-because the stale worktree declared the right version while sitting on the wrong
-commit, and only a tag can be checked. Copying from unreleased work is still
-possible, with `--allow-unreleased`, because it is occasionally correct; it just
-has to be said out loud. Making the wrong refresh hard is more of the point than
-making the right one convenient.
-
-**The capture is deliberately not copied at test time.** Doing that would undo
-both things vendoring bought. It would put the cross-repo dependency back --

# Test fixtures
-Two kinds of vendored byte copy live here, on the same terms: committed rather than generated, held to their source by a guard, and exempt from the formatters
-because in both cases the bytes are the artifact.
+The files here are committed source this repository owns, with one exception: the **historical `pyproject.toml` copies** (`pyproject_*.toml`) are this
+repository's own file at the two commits where the library path override went wrong, held to those commits by a guard.
-**Adapter captures** (`schema_*.json`) are real schema-adapter inputs, used by the field-path conformance tests via `tests/adapter_fixtures.py`. They are
-committed so the test suite has no cross-repo dependency and no runtime wheel has to keep shipping test data for this repository's benefit. The cost of a copy
-is that it can go stale, which for `schema_one_tree.json` is answered by the two guards below. Everything from here to "Why the flat capture has no byte guard"
-is about them.
-
-**Historical `pyproject.toml` copies** (`pyproject_*.toml`) are this repository's own file at the two commits where the library path override went wrong. See
-"[The historical pyproject copies](#the-historical-pyproject-copies)".
-
-## Provenance
-
-Both are byte-identical copies from the `span-panel-api` repository:
-
-| File here | Source in `$SPAN_PANEL_API_DIR` | Guarded by |
-| ------------------------ | ------------------------------------------------- | ------------------------ |
-| `schema_zero_types.json` | `tests/reference_payloads/homie_schema.json` | nothing |
-| `schema_one_tree.json` | `tests/reference_payloads/parent_child_tree.json` | `schema_one_tree.source` |
-
-Refresh by copying them again, and keep `schema_one_tree.json` byte-identical to its source: the library pins what that capture leaves unvalued against
-panelbench's own baseline (`tests/test_reference_tree_values.py` there), so a copy that has drifted puts these tests on a wire no producer sends.
-
-Both payloads shipped as package data until recently, and this repository imported them from the installed wheels rather than copying them:
-
-| File here | Path before `span-panel-api#162` |
-| ------------------------ | ----------------------------------------------------------------------------------------- |
-| `schema_zero_types.json` | `src/span_panel_api/reference_payloads/homie_schema.json` |
-| `schema_one_tree.json` | `tests/reference_payloads/parent_child_tree.json` |
-
-`span-panel-api#162` takes both back out of the wheels and moves them to `tests/reference_payloads/`, so the paths in the first table are the ones to copy from
-now. The byte comparison below checks both locations for the tree, newest first, so it works against a checkout on either side of that merge; the older path can
-be dropped once no release this repository can pin still predates it.
-
-`schema_zero_types.json` has been verified byte-identical to `homie_schema.json` at `schema-1-v1.0.0`, `v3.0.1`, `main`, and the post-#162 location — the
-bootstrap payload has not moved a byte across any of them. It has no automated guard: see "Why the flat capture has no byte guard" below.
-
-If a copy changes shape rather than content, the loader in `tests/adapter_fixtures.py` is what needs updating — note that `schema_one_tree.json` is a **dict
-keyed by device id**, whose `$description` value is a **JSON string**, not a parsed object. `tests/test_fixture_provenance.py` pins that shape, so a capture
-that arrives pre-parsed fails there rather than somewhere far from the fixture.
-
-## The two guards
-
-They catch different failures, and neither one substitutes for the other.
-
-| Guard | Compares | Catches | Needs a checkout |
-| --------------- | ----------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------- | ---------------- |
-| Version claim | `schema_one_tree.source` against the installed distribution | a pin that moved while the copy stayed put | no |
-| Byte comparison | `schema_one_tree.json` against the capture in that release | a copy that was refreshed **wrongly** — reformatted, edited, or taken from a working tree ahead of the release it names | yes |
-
-### The version claim
-
-`schema_one_tree.source` records the release the capture was copied from, as a pinned requirement:
-
-```text
-span-panel-api-schema-1==1.1.1
-```
-
-`tests/test_fixture_provenance.py` holds that against `importlib.metadata.version("span-panel-api-schema-1")` — the release actually installed. When the pin in
-`manifest.json` moves and nobody refreshes the capture, that test fails and names the refresh, so staleness is loud rather than silent. It needs no checkout of
-the library and no network call, which is why it runs everywhere and why a copy is safe to keep here at all.
-
-It is a separate file rather than a key inside the payload because a refresh is a byte-for-byte copy: anything added to the JSON would be overwritten by the
-next one. It names the distribution as well as the version because this repository pins three of them.
-
-What it cannot see is the bytes. A capture edited in place, reindented on the way in, or copied from a working tree that is ahead of the release it names
-satisfies this guard completely — the claim is a string, and the string is correct.
-
-### The byte comparison
-
-`test_the_vendored_capture_is_byte_identical_to_its_source` closes exactly that hole. It reads `SPAN_PANEL_API_DIR` (see `.env.example`), confirms the checkout
-is on the release `schema_one_tree.source` names, and compares the vendored copy against the capture there byte for byte, with no reformatting tolerance.
-
-The release check is not decoration. Written without it, the comparison passed against a checkout sitting one release behind the recorded one, whose bytes
-happened to be the ones vendored here — proving only that the copy matched _something_, and "something" includes the working tree it was mistakenly taken from.
-
-**A skip here is not a pass.** Without a checkout, or with one on another release, the comparison skips: not every developer keeps a sibling checkout, and
-failing them for it is what gets a check deleted rather than configured. Under `CI` it fails instead, because the workflow clones `span-panel-api` at the
-release the pin names, so an unset or misplaced path there means the wiring has come undone rather than that the check is unavailable. `span-panel-api` paid for
-this asymmetry and states the reason plainly in its `DEVELOPMENT.md`, under "A skip here is not a pass": _"A skip reads in a summary line exactly like a pass,
-and that is how a stale vendored capture went unnoticed for nine days."_ Do not make the skip unconditional.
-
-CI derives the tag from `schema_one_tree.source` rather than hardcoding it — `span-panel-api-schema-1==1.1.0` becomes `schema-1-v1.1.0` — so there is no second
-copy of the pin that could disagree with the first.
-
-### What it caught the first time it ran
-
-Worth recording, because it is the failure mode the guard was built for and it had already happened.
-
-`schema_one_tree.json` was vendored from a **stale sibling checkout**. `pyproject.toml` pointed its `[tool.uv.sources]` path overrides at a `span-panel-api`
-worktree that predated span-panel-api#161, so `span_panel_api_schema_1.reference_payloads` resolved there, and the copy inherited a capture that still recorded
-the emitter's `$settable` defect on a locked relay together with `load-shed/priority` values (`UNKNOWN`) that no producer publishes. The copy itself was
-faithful — byte-identical to the `schema-1-v1.0.0` release artifact — and `schema_one_tree.source` claimed 1.1.0. Both halves looked right in isolation; only
-holding the bytes against the release the claim names showed the mismatch.
-
-Nothing else in either repository could see it. The version guard compared a string to a string and passed. The conformance tests passed, because they were
-asserting against the capture. The integration was testing its locked-circuit and priority-settability work against a producer defect that upstream had already
-fixed.
-
-The fix was to repoint the path overrides at a checkout that tracks `main` and re-vendor. A path override redirects what every import in the suite resolves to,
-so one aimed at a stale checkout quietly tests against a producer that no longer exists — worth checking before believing any fixture taken through one.
-
-### Refreshing
-
-Either guard failing names the refresh, and the refresh is one command:
-
-```bash
-# SPAN_PANEL_API_DIR names the checkout; see .env.example
-uv run python scripts/refresh-vendored-capture.py
-```
-
-Commit both files it touches together — they are one fact in two files.
-
-What it does, for anyone reading this without the checkout to hand:
-
-1. Copies `tests/reference_payloads/parent_child_tree.json` from `$SPAN_PANEL_API_DIR` over `schema_one_tree.json`, byte for byte — `shutil.copyfile`, never a
- `json.load`/`json.dump` round trip, which would rewrite indentation, key order and float spelling and produce exactly what the byte comparison rejects. It
- checks the pre-#162 package-data path as a fallback, so it works against a checkout on either side of that merge.
-2. Writes `schema_one_tree.source` from the **installed** distribution's version, rather than from anything typed in.
-
-**Doing both from one command is the point, not the convenience.** The bytes and the recorded release used to be updated by two different actions, so doing one
-and not the other was a single missed keystroke — and the result was a capture whose claim about itself was wrong, which every conformance test then passed
-against. One command cannot do half of it.
-
-It refuses rather than guesses: no `SPAN_PANEL_API_DIR`, a path that does not resolve, a directory that is not a checkout, a checkout whose schema-1 release is
-not the one installed, a checkout with the file at neither location, or a checkout that is not standing on the release's tag. That last one is the one that
-matters: the refresh that went wrong copied from a worktree that _declared_ the installed release while sitting on unreleased work behind `main`, so the
-declaration and the pin agreed while the bytes were a release old. A version in a working tree is intent; a tag is a fact, and only a tag can be checked.
-
-Copying from unreleased work is still possible with `--allow-unreleased`, because it is occasionally correct — the current copy is exactly that case, taken from
-`main` because `schema-1-v1.1.0` is not cut and the alternative was to keep shipping a capture that records a producer defect. It verifies against a `main`
-checkout today and will verify against the tag once 1.1.0 is released from these bytes; if `main` moves the capture again first, the guard says so, which is the
-whole point. What is never acceptable is a capture taken from a checkout _behind_ the recorded release — that is how this one went wrong.
-
-### Why the capture is not copied at test time
-
-Someone will eventually propose having the suite copy the fixture from `$SPAN_PANEL_API_DIR` on every run, so it can never be stale. It would undo both things
-vendoring bought.
-
-It puts the cross-repo dependency back — every test run needing a `span-panel-api` checkout, which is exactly what committing the bytes removed. And it makes
-the byte comparison vacuous: a copy compared against the thing it was just copied from can only ever pass. **Committed bytes that are allowed to disagree with
-their source are the whole mechanism.** That freedom to disagree is what let the comparison find a capture vendored from a stale path override, which nothing
-else in either repository could see. A fixture that silently re-syncs itself cannot report anything.
+The schema-adapter payloads the conformance tests replay are **not** here. They are package data of `span-panel-api-schema-0` and `span-panel-api-schema-1`,
+read out of the installed wheels by `tests/adapter_fixtures.py`; the pin in `custom_components/span_panel/manifest.json` is what says which capture the suite
+replays, and bumping the pin is what moves it.

-
-The reason is the whole point of the byte comparison: **these are captured bytes, not source we own.** A vendored fixture held byte-identical to its source and
-an unconditional formatter cannot both exist, and it is the formatter that has to yield. A capture reindented on the way in is one nothing upstream can hold to

-have been rewritten on commit, and the guard would then have failed against a source the copy genuinely matched when it was made.
-
-Prettier is excluded as a **precaution, not a fix.** It has never touched these files and caused none of the drift we have seen — nothing here runs it over JSON
-(`scripts/fix-markdown.sh` passes only `*.md` globs, `prek.toml` has no Prettier hook), and the drift the byte guard actually caught was a stale source
-checkout. The line still earns its place: `schema_zero_types.json` carries its producer's 4-space indentation, and Prettier under `.prettierrc` rewrites it from
-14675 to 11779 bytes. That file has no byte guard, so nothing would report it.
-
-The scope is two prefixes rather than the whole directory, because only the vendored byte copies have this property. `tests/fixtures/README.md` is prose this
-repository owns and should keep being formatted; the migration YAMLs are hand-written source; and `unread_declarations_baseline.json`, despite being a
-mechanically-checked inventory, is hand-maintained — its values are one-line human explanations. Each prefix is a vocabulary something already uses — `schema_*`
-is `tests/adapter_fixtures.py`'s for adapter captures, `pyproject_*` is `tests/test_library_path_hook.py`'s for historical copies of this repository's own
-`pyproject.toml` — so the next one vendored under either is covered without anyone remembering to widen the rule.
-
-The read-only hooks still cover these files, `check-json` and `check-toml` in particular. A copy that does not parse is worth hearing about wherever it came
-from.
+## The historical copies are exempt from formatting
-## Why the flat capture has no byte guard
+`tests/fixtures/pyproject_*.toml` is excluded from every hook that rewrites files — `trailing-whitespace`, `end-of-file-fixer` and `mixed-line-ending` in
+`prek.toml`. Prettier cannot format TOML, so `.prettierignore` needs no line for them.
-`schema_zero_types.json` is vendored on the same terms as the tree but has no `.source` file and no byte comparison, and that is a deliberate gap rather than an
-oversight.
+The reason is the whole point of the comparison: **these are captured bytes, not source we own.** A copy held byte-identical to a commit and an unconditional
+formatter cannot both exist, and it is the formatter that has to yield. A copy reindented on the way in fails against the commit it genuinely matched when it
+was made, and the resulting failure names the fixture rather than the hook that broke it — so the person debugging it starts in the wrong place.
-It comes from the **bootstrap** distribution, `span-panel-api`, which is released on its own tag line (`v3.1.0`), while the tree comes from
-`span-panel-api-schema-1` (`schema-1-v1.1.0`). CI clones the library once, at one revision. A checkout positioned at the schema-1 tag holds the bootstrap
-sources at whatever state they happened to be in at that commit, which is not the same thing as a bootstrap _release_ — so a byte comparison there would be
-against an arbitrary revision, which is exactly the "proves only that the copy matches something" failure the tree's release check exists to prevent.
+It is not hypothetical, only untriggered so far. Those three hooks cover `tests/`, and they leave the copies alone only because both happen to be
+newline-terminated with LF endings and no trailing whitespace. The first one vendored without a final newline would be rewritten on commit.
-Guarding it properly means either a second checkout at the bootstrap tag or a second job, and neither is free. Against that: the payload has been byte-stable
-upstream across every revision checked. The gap is recorded here so the next person weighs it rather than rediscovering it.
+The scope is one prefix rather than the whole directory, because only these copies have this property. `tests/fixtures/README.md` is prose this repository owns
+and should keep being formatted; the migration YAMLs are hand-written source; and `unread_declarations_baseline.json`, despite being a mechanically-checked
+inventory, is hand-maintained — its values are one-line human explanations. `pyproject_*` is `tests/test_library_path_hook.py`'s own vocabulary, so the next
+copy taken under it is covered without anyone remembering to widen the rule.
-## Derived variants
+The read-only hooks still cover these files, `check-toml` in particular. A copy that does not parse is worth hearing about wherever it came from.
-The batteryless and PV-less trees are **derived in memory**, not committed: `adapter_fixtures.schema_one_tree(without="bess")` and `without="pv"` return the
-capture with that one device dropped. They were separate files once; deriving them means they cannot drift from the base, since the only difference either ever
-had was the one missing device. Each drops exactly one device (13 -> 12) and retains the panel and both lugs devices — a variant that removed more would make
-the conformance tests pass for the wrong reason. Note `bess-mid` is typed `energy.ebus.device.mid` and is not the BESS.
+## Derived variants of the parent/child capture
-## Why these exist
+The batteryless and PV-less trees are **derived in memory**: `adapter_fixtures.schema_one_tree(without="bess")` and `without="pv"` return the adapter's capture
+with that one device dropped. They were separate files once; deriving them means they cannot drift from the base, since the only difference either ever had was
+the one missing device. Each drops exactly one device (14 -> 13) and retains the panel and both lugs devices — a variant that removed more would make the
+conformance tests pass for the wrong reason. Note `bess-mid` is typed `energy.ebus.device.mid` and is not the BESS.
The batteryless tree proves a panel with no BESS produces **no** `battery.*` entries — hardware absence, not degradation. The PV-less tree proves the same for a
panel that has power-flows telemetry but no PV device, which is the case telemetry-based capability detection gets wrong.

-"""The vendored capture must name the release it came from, and be right about it.
-
-`tests/fixtures/schema_one_tree.json` is a byte-identical copy of a payload that
-lives in the `span-panel-api` repository. Committing it is what keeps this suite
-free of a cross-repo dependency, and free of the expectation that a runtime wheel
-keeps shipping test data. The price of a copy is that it can go stale, and a
-stale capture is the worst kind of green: the conformance tests keep passing,
-against a wire no panel sends.
-
-Detecting that does not need the file, only the version claim. `schema_one_tree.source`
-records the release the copy was taken from, and `importlib.metadata` reports the
-release actually installed -- with no checkout, no network call and no second copy
-to compare against. The moment the pin moves and the capture is not refreshed,
-this test fails and says what to do about it.
-
-That is half the problem. A version claim catches a copy that was never
-refreshed; it cannot catch one that was refreshed *wrongly* -- reformatted,
-hand-edited, or taken from a working tree ahead of the release it names -- because
-those leave the claim intact and change only the bytes. So the second guard here
-compares the bytes, against the capture in a `span-panel-api` checkout named by
-`SPAN_PANEL_API_DIR`. It needs something the version guard deliberately does not,
-and therefore skips when no checkout is configured -- but **fails** rather than
-skips under `CI`, where the workflow clones one. The library states the reason
-plainly, having paid for it: "A skip reads in a summary line exactly like a pass,
-and that is how a stale vendored capture went unnoticed for nine days"
-(`span-panel-api`, DEVELOPMENT.md, "A skip here is not a pass"). Anyone tempted to
-make the skip unconditional should read that first.
-
-This is one test rather than a check inside `adapter_fixtures.schema_one_tree()`
-deliberately. Stale provenance is a maintenance fact, not a broken payload: the
-capture still parses and still drives every adapter. A loader-level assertion
-would turn one actionable failure into several hundred identical ones, burying
-whatever else the run had to say -- and it would make the refresh itself
-undebuggable, since the bump and the copy cannot land in the same keystroke.

## [2.1.0] - 8/2026
-### You will need this release before SPAN updates your panel
-
-SPAN firmware `r202633` replaces the way the panel publishes its data — the wire model every release up to 2.0.8 is retired in the same update that introduces
-the new one. There is no wire overlap and no setting to keep the old behaviour. **2.0.8 cannot read a panel on `r202633`**: it stays connected, reports every
-circuit as missing, and shows nothing useful.
+### In short
+
+- **Install this before SPAN pushes firmware `r202633`** — it replaces the panel's wire model, and 2.0.8 cannot read a panel that has taken it. Requires Home
+ Assistant 2026.8.
+- **The Microgrid Interconnect Device and the solar inverter become devices of their own**, carrying grid health and whether Grid Power is really measuring the
+ grid.
+- **EVSE Charge Current Limit** is the first control here that changes something on a SPAN Drive rather than on the panel.
+- **The battery says when things run out** — Time to Priority Shed and Backup Time Remaining, beside its own power and link state.
+- **Vendor extensions are adopted on a reload**, so a device type or reading nobody has modelled no longer waits for a release.
+- **Your passphrase is no longer stored and the panel's certificate is pinned before credentials cross the network**, with control lockable or admin-only.
+- **Nothing you have moves** — entity ids, unique ids and history survive the upgrade.
-**The transition itself is seamless.** Install 2.1.0 early and your only outage is the firmware update itself. A log line and a one-time notification tell you
-exactly what happened, so take a screenshot.
+### You will need this release before SPAN updates your panel
-**A panel that is still rebooting is waited out, for as long as your panel takes.** Taking the firmware upgrade drops the panel's connection for several minutes
-— four or more is not uncommon once the panel receives its upgrade file. If you experience an extended delay (over 5 minutes), reload the integration (reload is
-a menu item, not a reinstallation).
+SPAN firmware `r202633` replaces the wire model and introduces the new one on reboot. **2.0.8 cannot read a panel on `r202633`.**
### Requires Home Assistant 2026.8.0 or newer
-This release raises the minimum from 2026.5.4. Home Assistant 2026.8 replaced the two device-registry calls this integration relies on — the old forms stop
-working entirely in 2027.8.
+This release requires Home Assistant 2026.8 to avoid a deprecated API — the old API stops working entirely in 2027.8.

## Security
-### What the integration stores
-
-Setting up a v2 panel exchanges your panel passphrase for two long-lived secrets, which are kept in the config entry (`.storage/core.config_entries`):
-
-- the **eBus MQTT broker password**, which grants control of every relay, circuit priority, islanding state and EVSE limit on the panel and its sub-devices, and
-- the **REST access token**, which grants panel management — client registration, FQDN registration and credential rotation.
-
-The **panel passphrase itself is no longer stored.** It is an input to registration and nothing afterwards reads it, but a stored copy could mint fresh
-credentials at any time. Upgrading migrates the config entry to version 7 and removes it; nothing else in the entry changes and no entity is affected. If you
-have not yet upgraded, reauthenticating also removes it.
-
-> **Downgrade note.** Once an entry has reached version 7, installing an older build of the integration will fail to set it up — Home Assistant refuses to load
-> a config entry whose version is newer than the installed integration supports. Restore a backup taken before the upgrade if you need to roll back.
-
These are the limits of what the integration can enforce. Anything that already holds the broker password — including another integration running in the same
Home Assistant process — talks to the panel directly and is not subject to Home Assistant's permission model at all.
-### The panel's certificate authority
-
-The panel issues its own certificate authority and signs its TLS certificate with it. **Before you are asked for your passphrase**, setup fetches that
-authority, checks that the certificate the panel actually serves is signed by it, and pins it. Everything after that — registration itself, and every later
-connection — runs over that authority, and the integration stops rather than accepting a different one.
-
-The ordering is the point. Registration is the exchange that sends your passphrase and returns both the access token and the broker password, so it is the
-single most valuable message on your network. It now travels over a verified connection instead of in the clear.
-
**What that does and does not buy you.** The authority is fetched over your local network on a connection that has nothing to verify itself against — it is the
anchor everything else is checked against. So:
-- Anyone merely **listening** on your network can no longer read your passphrase or the credentials the panel returns for it. That is the common case, and it is
- closed.
+- Anyone merely **listening** on your network cannot read your passphrase or the credentials the panel returns for it.
- A device **actively standing between** Home Assistant and your panel at that first fetch could answer with an authority of its own, sign a certificate with
it, and still see them. Pinning cannot detect that on its own.
-Comparing the fingerprint against another source is what closes the second case. Setup does not stop to ask you to do that, because at first contact there is
-nothing to compare against: SPAN does not publish the value, so the question could only be answered by pressing Submit. The fingerprint is put where it can
-actually be used instead — diagnostics report it under `panel_ca`, it is logged at setup, and another install of this integration on the same panel reports the
-same value.
-
-After the first pin, nothing can change the authority without stopping and asking you — and _that_ is a question you can answer, because there is a prior value
-to compare against. See the certificate-authority-changed entry in Troubleshooting.

-- **It is no longer an attribute of the Software Version sensor**, so a template reading `state_attr('sensor.span_panel_software_version', 'wifi_ssid')` should

-- **Circuit entity ids are now composed by Home Assistant from your own entity-id settings**, the way every other entity this integration creates already was:

- name, and the area as well if your entity-id settings (`entity_id_parts`) include it.

- **A panel device you renamed yourself is offered ids carrying that name**, since Home Assistant composes from the name you gave the device ahead of the one

- **New installations provide uniform circuit energy sensor ids — `consumed_energy`, `produced_energy` and `net_energy`**, in line with the panel-level energy
sensors.
- **A newly commissioned SPAN Drive's feed-circuit sensors are named for the charger** — `sensor._power`, matching the charger's other sensors; the
ones you already have keep their ids.
-- **An unnamed circuit in friendly-names mode is now named for the tab it occupies** (`Circuit 7 Power`), so two unnamed circuits no longer collide — the old
- scheme called every one of them `single_circuit` and let the registry tell them apart with `_2`, `_3`.

-- **Circuit-numbers installations now show the device in the displayed name** — `Span Panel Kitchen Outlets Power`, as friendly-names installations always have
- — so a template or a voice alias matching the old exact string needs updating.
### Fixed
- **Energy dip compensation no longer books a dip that never happened** (#259), where a partial reading at startup looked like a counter reset and every restart
added each circuit's whole lifetime counter to its offset.
-- **A compensated dip stays provisional until it settles, and is only reported then**: it is compensated the moment it is seen, corroborated by a reading that
- climbs from the new low base, held for three further readings during which the counter returning to where it started takes that dip's whole compensation back,
- and named in a notification once that window closes — so a burst of stale samples cannot leave a permanent step in your energy statistics or a notice for an
- event that did not happen.
- **A panel this integration can no longer reach makes its entities unavailable instead of reporting 0 W** — a certificate authority that changes mid-session
used to leave every power sensor reading zero and every energy sensor frozen, indefinitely and indistinguishably from a panel drawing no power.
- **Recreate entity IDs proposes the ids your panel would produce now** (#252), in your installation's naming style, leaving unique ids and statistics
untouched.
-- **The registry `Name` an older release wrote on circuit-numbers installations is handed back to you** at the first start after upgrading, for every label
- those sensors have ever carried, so that field is yours again and no longer decides what Recreate proposes.
-- **Enum sensors advertise the states they can actually report**, where nine sensors declared only `unknown` and `DSM Grid State` sitting at `On Grid` showed
- "Possible states: Unknown".
- **The README described Battery Power's sign backwards**, since the sensor has always reported discharging as positive (#184) and only the documentation was
ever wrong.
- **A breaker your panel refuses to operate now says so**, reporting the panel's own reason where you pressed it instead of a traceback in the log and a toggle
that quietly springs back.
- **A control command that never reached your panel now says so**, reported where you issued it rather than only in the log and stating plainly that nothing was
queued.
-- **A refused circuit priority no longer blames your firmware**, carrying the panel's own reason on the control you used rather than as a notification you
- dismiss by hand.
### Security
-- **New admin-only action `span_panel.rotate_credentials`** replaces the eBus MQTT broker password on demand, which immediately breaks any other local client
- using the old one.
- **The panel's certificate authority is pinned before your passphrase is ever sent**, so the registration exchange that carries it — and everything after — no
longer crosses your network in the clear.
-- **Re-authenticating an entry that was never pinned pins it first**, so an entry that arrived from an older release sends its new credentials over a verified
- connection and keeps the authority afterwards.
-- **A pinned entry is never left holding an address its own certificate does not name**, which would have produced an entry unable to reach the panel it was
- just set up against, with no flow left to correct it.
-- **Continuing past a failed domain registration now keeps the panel rather than the name**, recording the address that got that far and claiming no registered
- domain, so the entry works and the domain can be tried again from **Reconfigure** once whatever blocked it is fixed.
-- **An entry upgraded from before pinning checks the authority it fetched against the certificate the panel serves on the broker port before storing it**, so a
- reverse proxy or anything else answering that fetch cannot become the authority the integration then trusts forever.
-- **The same check now guards the repair that asks you to accept a changed authority**, and a value that fails it is refused rather than offered to you as a
- fingerprint to approve.
-- **An mDNS announcement or a re-added panel only moves a pinned entry's address when the new address serves a certificate that entry's authority validates** —
- previously any device on your network could claim your panel's serial and have the entry pointed at itself, after which the changed-authority repair invited
- you to accept the impostor's fingerprint.
- **A changed authority stops the integration and raises a repair** carrying both fingerprints, because a legitimate rotation and an impersonated panel look
identical from here.
-- **`span_panel.rotate_credentials` asks which panel when more than one is loaded** instead of rotating the first it finds, since the previous broker password
- stops working for every other local client of whichever panel it picked.
-- **It reports a reload that did not come back** rather than logging success, and says the new password was already stored so nobody rotates a second time and
- invalidates the one the panel has accepted.
-- **It refuses to run at all when the stored authority cannot be read**, rather than carrying the access token out and the new broker password back over an
- unverified connection; repair the authority first.
- **Four new options decide who may operate the panel** — administrators only, no commands without a logged-in user, an admin-only control lock, and a relay
debounce — every one defaulting to what your panel already does.
- **`Administrators only` does not cover an automation a non-admin triggered**, because Home Assistant gives an automation a fresh context with no user on it
and there is then nothing to hold to the admin test; switch off **Allow control without a logged-in user** if you want those refused too.
-- **Choosing `Nobody` now refuses control commands as well as creating no controls**, so the option is enforced where commands are published rather than only by
- the absence of entities to press.
-- **The control lock arrives armed and stays where you left it**, so turning the option on locks control straight away and a restart or a settings save no
- longer quietly unlocks the panel; a pending auto-relock comes back with the time it had left rather than starting its countdown over.
-- **A control lock whose pending countdown cannot be read comes back armed** rather than opening a fresh window nobody asked for — which is what a record
- written by an older release looks like on the first restart after upgrading.
-- **The relay debounce counts only commands the panel was actually sent**, so a breaker command the broker never took no longer refuses your immediate retry
- with "operated less than 2 seconds ago".
-- **A circuit the panel starts or stops letting you operate gains or loses its breaker switch and its priority control on the next reload**, which the
- integration asks for as soon as it notices — both directions, rather than leaving you a control the panel refuses every press of or no control where the panel
- now allows one.
- **Every control command is now recorded** in the logbook, on the event bus as `span_panel_control_command`, and at `INFO`, attributed to the automation that
issued it rather than to nobody.
-- **Every control now reports what happened to it**, adopted devices' controls included, so a command that was refused or never handed to the broker no longer
- looks like one the panel confirmed.
-- **A new [Security](README.md#security) section in the README** covers what the integration stores, what rotation costs, and the deployment choices that
- actually bound the panel's exposure.
+- **A new [Security](README.md#security) section in the README** covers what rotation costs and the deployment choices that actually bound the panel's exposure.
### Known limitations
-- **A panel reachable only by a single-label name cannot complete a pinned setup by that name** — the SPAN simulator add-on and anything else whose certificate
- names only its IP address — because nothing registers a name that is not a fully qualified domain, so the certificate never comes to name it; set the panel up
- by its IP address instead.
-- **An upgraded entry whose broker port does not serve a certificate the panel's own authority signs stays unpinned** — a proxy terminating TLS with a
- certificate of its own, say — logging a warning at every start and raising no repair. **Reauthenticate** is the route that does the check on screen: it asks
- for the TLS port and refuses with an error if the authority does not sign what the panel serves. Reconfiguring the entry to the panel's own address instead
- leaves the pin to the reload that follows, which happens silently — watch the log for "Pinned the CA advertised by…". The reverse arrangement — a proxy
- terminating only port 443, so that the panel's own authority signs the broker's certificate but not the one served on the HTTPS port — does pin at that
- reload, and every path that then talks to the panel over HTTPS (**Reauthenticate**, **Reconfigure**, **Rotate credentials**) refuses rather than sending your
- token unencrypted, until port 443 also serves the panel's own certificate.
+- **A panel reachable only by a single-label name — one with no dot and no domain — cannot complete a pinned setup by that name**, because nothing registers a
+ name that is not a fully qualified domain, so the certificate never comes to name it. Set that panel up by its IP address, or by the `.local` name shown in
+ the mobile app.
- **A discovered address this entry's authority rejects is refused with a log warning and nothing else** — if the panel really has moved, use **Reconfigure** on
the entry, which checks the new address against the standing pin before storing it.
-- **A panel discovered through the Supervisor is deliberately not held to the address check** the other discovery routes are, because a Home Assistant add-on
- arrives over the authenticated Supervisor API and legitimately reallocates its own ports; an add-on with Supervisor privileges can therefore move a pinned
- entry.

Subject: [PATCH 216/345] fix(config_flow): tell a moved panel apart from an
impersonated one
A pinned entry whose panel changed DHCP lease had no way back. The panel
serves a perfectly good certificate that no longer names where it answers,
and `async_leaf_chains_to_ca` returned one boolean for "does not chain" and
"does not name this host" alike, so:
- reconfigure refused with "not signed by the authority it published",
which was false -- it was signed, by exactly that authority;
- the mDNS move-guard refused on the same check;
- reauth reads the stored host and offers no field to change it;
- the CA-changed repair never fired, because the CA had not changed.
Deleting and re-adding the entry was the only route left, for a panel that
had done nothing but take a new address.
`async_leaf_verdict` answers the three questions separately -- TRUSTED,
NAME_MISMATCH, UNTRUSTED -- plus UNREACHABLE, which had been folded into
the same value, so an unplugged cable was reported to users as an unsigned
certificate. `async_leaf_chains_to_ca` stays as a wrapper for TRUSTED, so
every existing caller keeps the meaning it had.
Classification alone would have fixed nothing: `detect_api_version` and
`register_fqdn` run over the entry's pinned transport, and both would fail
the same hostname check before registration could repair anything. So on
NAME_MISMATCH the reconfigure flow rebuilds its own transport with the pin
kept and only the name binding dropped. It probes, registers the FQDN, and
the panel regenerates its certificate around the new name. That transport
never leaves the flow and is never stored.
A bare IP the certificate does not name is still refused, because this flow
can relax the name binding for its own probe and the coordinator and broker
cannot -- storing it would point the entry at an address every later
connection rejects. The new `ca_name_mismatch` error says so and names both
ways through: an FQDN, or the panel's .local name.
The relaxed context and the SAN matcher come from span-panel-api 3.2.0
rather than being written here. `ssl.match_hostname` was removed in 3.12,
so the matcher is hand-written, and a hand-written security primitive with
two implementations is the drift `_ssl`'s docstring warns about.

Subject: [PATCH 217/345] fix(config_flow): a moved panel with no address to
fall back to is refused
"Continue anyway" after a failed FQDN registration stored the name and
reported success. On every path but one that is the right trade: the flow
falls back to the address it reached the panel by, which the anchor
verified, so the entry lands somewhere usable.
The moved-panel path has no such address. Its certificate names neither
the FQDN nor anything reachable -- that is why the flow relaxed the name
binding for its own probe -- so `_fall_back_to_the_bootstrap_address` had
nothing to adopt and returned having changed nothing, and the flow then
wrote the unserved name behind a `reconfigure_successful` banner. Every
runtime connection would fail the hostname check the coordinator and the
broker apply and cannot relax: the stranded entry this branch refuses for
bare IP addresses, delivered as a success.
It now re-shows the form with `ca_name_mismatch` and leaves the entry
untouched, and the fallback's docstring no longer claims an invariant it
cannot restore without an address.
Also: an empty `getpeercert()` after a completed handshake now classifies
as UNTRUSTED rather than NAME_MISMATCH. `CERT_REQUIRED` should make it
unreachable, but NAME_MISMATCH is the verdict that unlocks the relaxed
transport, and "no validated certificate in hand" is not evidence that
anything holds a key the anchor signed.

Subject: [PATCH 218/345] test(config_flow): prove the refusal form is not a
dead end
The Finding A fix returns a `reconfigure` form from inside
`async_step_reconfigure_fqdn_failed`, which is only correct if submitting
it re-enters `async_step_reconfigure` and gets judged again. Asserted
rather than assumed: the test now submits the form it lands on and
confirms the flow is still live and the entry still untouched.

Subject: [PATCH 219/345] docs: make the security section guidance, not
narrative
The section had grown to explain its own reasoning inline, so a reader
looking for what to do worked through why each choice was made to find it.
The four situation-and-remedy paragraphs -- hostname setup, the mDNS move
guard, Reconfigure, and an entry with no anchor -- are a table now, which
leaves nowhere to put a justifying clause. 68 lines to 30.
The reasoning is kept, in developer.md under "Why the CA pinning behaves as
it does": why no fingerprint is offered at first contact, why diagnostics
carry the fingerprint and not the certificate, why an unreachable panel
does not stop setup, why reauth keeps the anchor it acquires, the
difference between pinning on screen and pinning during a reload, and why
a registered domain is checked when the panel reports it.
Corrections along the way:
- The deployment bullet named `tcp/80` for the REST bootstrap. A pinned
entry uses `tcp/443`; `tcp/80` is the plaintext CA fetch, and REST only
until the entry pins. Following it literally would have blocked every
REST call the moment pinning succeeded.
- "The changeover is designed to be seamless.**" had a closing bold marker
with no opener, so it rendered literally.
- The `r202633` sentence was never closed and "after the firmware hits"
dangled.
- "differ in two:" introduced four bullets, one of which is not a
difference.
- The prerequisite read as a floor; 2.0.8 is a required stepping stone.
- Install step 8 said "IP address or .local address".
- One `behavior` against the document's British spelling.
The adopted-device and adopted-vendor-reading sections move below the
entity tables. They had been sitting between the Microgrid Interconnect
Device and Power Sensor Attributes, so a reader working down the tables hit
fifty lines of vendor-extensibility prose and landed back in tables.
developer.md's Supervisor section pointed at a README paragraph that no
longer exists; the reference is dropped.

## Security
-There are limits to what the integration can enforce. Anything that already holds the eBus MQTT broker password — including another integration running in the
-same Home Assistant process — talks to the panel directly and is not subject to Home Assistant's permission model at all.
-
-**What pinning the panel's certificate authority does and does not buy you.** The authority is fetched over your local network on a connection that has nothing
-to verify itself against — it is the anchor everything else is checked against. So:
-
-- Anyone merely **listening** on your network cannot read your passphrase or the credentials the panel returns for it.
-- A device **actively standing between** Home Assistant and your panel at that first fetch could answer with an authority of its own, sign a certificate with
- it, and still see them. Pinning cannot detect that on its own.
-
-Comparing the fingerprint against another source is what closes the second case. At first contact there is nothing to compare against: SPAN does not publish the
-value, so the question could only be answered by pressing Submit. The fingerprint is put where it can actually be used instead — diagnostics report it under
-`panel_ca`, it is logged at setup, and another install of this integration on the same panel reports the same value.
-
-After the first pin, nothing can change the authority without stopping and asking you — there is a prior value to compare against. See the
-certificate-authority-changed entry in Troubleshooting.
-
-**Re-authenticating an entry that has no anchor acquires one first.** Reauth is a registration, so it carries the passphrase out and the broker password back —
-the same exchange setup performs. An entry that arrived from before pinning, or one whose stored authority will no longer load, goes through the
-certificate-authority step before either sign-in method is offered, and keeps the anchor afterwards instead of falling back to a plaintext fetch on every
-connection.
-
-**Setting a panel up by hostname works, and the hostname is verified.** A panel's certificate names the addresses it already knows itself by; a domain joins
-that list only when the integration asks the panel to regenerate its certificate, which happens after you have authenticated. Everything before that runs
-against the address the certificate already names, hostname verification never relaxed, and the domain is checked once the panel reports the new certificate.
-
-**A pinned entry follows its panel to a new address only when the new address proves itself.** An entry moves when your panel announces itself over mDNS at a
-new address, and when you add the same panel again by hand. Both used to be decided by a serial read from an unauthenticated endpoint, which anything on your
-network can claim. The entry now asks whether the candidate serves a certificate its own anchor validates, on the port the entry uses, and refuses the move —
-logging at `WARNING` — otherwise. If the panel really has moved, use **Reconfigure** on the entry.
-
-**Reconfigure tells a moved panel apart from an impersonated one.** A panel that changed address serves a perfectly good certificate that does not yet name
-where it now answers, and something impersonating your panel serves one that chains to nothing — the same failure, until you ask which. Reconfigure asks. A host
-that does not chain to the pinned authority is refused as before, and one that does not answer at all is now reported as unreachable rather than as an unsigned
-certificate. A host that chains but is not named is your panel, and the way through is to reconfigure to a **fully qualified domain name**, which asks the panel
-to regenerate its certificate around that name, or to the panel's **`.local` name**, which its certificate already covers. Reconfiguring to a bare new IP
-address the certificate does not name is refused, because the entry would then be pointed at an address every later connection rejects.
-
-**Panels configured before this release are pinned differently, and are not risk-free until they are.** They are pinned on the first startup that reaches the
-panel, logged at `WARNING` with the fingerprint so you can find the value afterwards. What was fetched is checked against the certificate the panel serves on
-the broker port — the connection the anchor is actually used for — and an authority that signs nothing the panel serves is not stored. Until a pin succeeds, the
-connection to the broker still authenticates with your panel's password while the authority is re-fetched over plaintext HTTP on every connection and whatever
-answers is trusted — the substitution pinning exists to close.
+**The integration cannot enforce much on its own.** Anything holding the eBus broker password — including another integration in the same Home Assistant process
+— talks to the panel directly, outside Home Assistant's permission model.
-If the panel is unreachable the integration starts anyway and retries on the next startup. That is deliberate. The exposure in the meantime is exactly the one
-the entry already had before this release, and refusing to start would not remove it — it would only remove the integration, leaving the credential no safer
-while guaranteeing an outage. Retrying closes it at the first opportunity instead.
+**What pinning the panel's certificate authority buys.** The authority is fetched over your network on a connection with nothing to verify itself against,
+because it _is_ the anchor everything else is checked against:
-The same is true of an entry whose broker port does not serve a certificate the panel's own authority signs — a proxy terminating TLS with a certificate of its
-own, say. It stays unpinned and logs that warning at every start, and no repair is raised for it.
+- A **listener** cannot read your passphrase or the credentials the panel returns for it.
+- A device **actively in the path at that first fetch** can answer with an authority of its own and read both. Pinning alone cannot detect this.
-The reverse arrangement has the opposite cost. Where a proxy terminates only port 443, the panel's own authority still signs the broker's certificate, so the
-entry pins at the reload — and the anchor is then also what every REST call to the panel is verified against. **Reauthenticate**, **Reconfigure** and **Rotate
-credentials** all refuse, rather than send your access token unencrypted, until port 443 serves the panel's own certificate too.
+Comparing the fingerprint against another source closes the second case. It is in diagnostics under `panel_ca`, in the setup log, and reported identically by
+another install of this integration on the same panel. After the first pin, any change stops the integration and raises a repair — see Troubleshooting.
-**Reauthenticate is the route that does this on screen.** An unpinned entry sent through **Reauthenticate** goes to the certificate-authority step first, which
-asks for the TLS port where the HTTP port has been moved — the install most likely to be behind a proxy — and refuses with an error if the authority does not
-sign what the panel serves. Reconfiguring the entry to the panel's own address is the other way through, but the pin then happens during the reload that
-follows, silently: the only announcement is a `WARNING` reading "Pinned the CA advertised by SPAN panel …" with the fingerprint.

+## Why the CA pinning behaves as it does
+
+The README says what the pinning does; this is why each of those choices was made rather than the obvious alternative. All of it was written for the README and

+
+**The fingerprint is not shown at first contact, on purpose.** Comparing it against another source is what closes the active-in-path case, and at first contact
+there is nothing to compare against — SPAN does not publish the value, so the question could only ever be answered by pressing Submit. A dialog that asks a
+question the user cannot answer trains them to dismiss it, which costs the one time it matters. So the value is put where it can actually be used instead:
+diagnostics under `panel_ca`, the setup log, and any other install of this integration on the same panel.
+
+**Diagnostics carry the fingerprint and not the certificate.** The certificate is public, so withholding it buys no secrecy — it is omitted because it is
+multi-KB and the fingerprint is the part anyone reads.
+
+**An unreachable panel does not stop setup.** The integration starts anyway and retries on the next startup. The exposure in the meantime is exactly the one the
+entry already had before pinning existed, and refusing to start would not remove it — it would remove the integration, leaving the credential no safer while
+guaranteeing an outage. Retrying closes the window at the first opportunity instead.
+
+**Reauth keeps the anchor it acquires.** An entry that predates pinning, or whose stored authority no longer loads, goes through the certificate-authority step
+before either sign-in method is offered, and keeps the anchor afterwards rather than falling back to a plaintext fetch on every connection. Reauth is a
+registration — it carries the passphrase out and the broker password back, the same exchange setup performs — so it is the one flow where acquiring an anchor
+first is worth a step in front of the user.
+
+**Reauthenticate is the route that pins on screen; Reconfigure pins silently.** The certificate-authority step asks for the TLS port where the HTTP port has
+been moved — the install most likely to be behind a proxy — and errors if the authority does not sign what the panel serves. Reconfiguring the entry to the
+panel's own address reaches the same place, but the pin then happens during the reload that follows, announced only by a `WARNING` reading "Pinned the CA

Subject: [PATCH 220/345] fix(repairs): tell the user when the panel is not at
the configured address
A pinned CA that still validates the panel's certificate, on a handshake
that fails anyway, means one of two things the library used to conflate: an
expired leaf, which fixes itself, and a certificate that does not name the
configured host, which never will. 3.3.0 tells the two apart and reports
the second on a callback of its own; this subscribes to it and puts the
remedy in front of a person.
`leaf_repairs.py` follows `ca_repairs` in shape and the `schema_repairs`
reconciliation model in substance: not persistent, because the transport is
alive and re-derives the condition on every attempt; WARNING, because
nothing was intercepted and nothing refused; not fixable, because
Reconfigure is the remedy, already refuses a host the leaf does not name,
and a fix flow cannot hand off to a config flow.
Subscribed before `connect()` rather than after it, unlike every other
callback here. The library runs the diagnosis inside the first connect and
a mismatch makes it raise, so setup raises ConfigEntryNotReady and the
retry builds a new client -- a subscription after a successful connect
would never see the case it exists for.
Cleared on the coordinator's connection edge, which is the exact event the
library re-arms its own once-per-outage signal on, and at setup beside the
CA one. A CA change on the same entry supersedes it: only that finding
carries a security decision, and pointing somebody at an address served by
a certificate just refused is the wrong instruction.
Two translation keys rather than one. A placeholder is substituted
verbatim, so a certificate naming no address at all gets a description of
its own instead of an English phrase passed through {leaf_names}.
Requires span-panel-api 3.3.0, which is not yet on PyPI.

+"""Tests for the Repair raised when the panel's certificate does not name the host.
+
+The condition this covers is the one the library used to report to nobody: a
+handshake that fails against a pin the panel still advertises, because the
+certificate underneath names an address the entry does not use. The user was left
+with a minute-by-minute log warning, every entity unavailable, and nothing in the
+UI at all.
+
+The wiring is the substance of it, so most of these tests are about *where* the
+subscription happens rather than what it does with the signal. The library runs
+the diagnosis inside `connect()`, and a mismatch makes `connect()` raise, so a
+subscription placed after it -- the natural place, and where the fatal-error one
+lives -- would never see the case it exists for.

Subject: [PATCH 221/345] fix(config_flow): a Supervisor discovery reallocates
ports, not the host
`async_step_hassio` put the add-on's published host straight into the
already-configured update on every add-on start. Observed on ha-test: an
entry configured at an address that reached the panel and that the panel's
certificate names was overwritten with the add-on's container hostname, a
name the panel does not serve, 56 seconds after the entry was created.
Every connection afterwards failed verification against the entry's own
pin. The update also moved `host` without `ebus_broker_host`, leaving the
entry naming two different machines.
The docstring's argument for being unguarded -- add-ons legitimately
reallocate their own ports -- covers the ports and does not reach the host.
An add-on that moved a port has not moved the panel.
So the ports still go straight in, and `_async_hassio_host_update` decides
the host on the evidence the entry already has: probe the *configured* host
on the *newly discovered* port, which is precisely the reallocated-port
case, and keep the stored host when a v2 answer there carries this serial.
Only a configured host that has stopped answering for this panel is
replaced, and then `CONF_HOST` and `CONF_EBUS_BROKER_HOST` move together.
Deliberately not `_async_host_update`'s pinned-address check. That one
decides whether an unauthenticated claim may move an entry; this one
decides whether there is anything to move at all. The Supervisor route's
documented trade is unchanged for a host that has genuinely gone away.
Bumps the integration to 2.1.0b23 and re-mirrors pyproject's version onto
the manifest's, which had drifted at 2.1.0.

Subject: [PATCH 230/345] feat(curation): load the overlay at setup, ahead of
the platforms
Read the stored overlay into runtime data before the platforms are forwarded,
so every adopted entity is born with its curated metadata rather than having it
applied after its first state is written. The field is required rather than
defaulted: a setup path that forgets the load has to fail loudly, because an
empty overlay is indistinguishable from a user who has curated nothing.
Removing the entry forgets the store, as it already forgets the announcement
record. The keys are wire addresses rather than registry ids, so a store left
behind is one the next entry for the same panel would load and apply.

+"""WebSocket commands for curating adopted entities.

+Separate from `websocket.py` because the two answer different questions about
+the same panel. That module reports the *curated* topology -- circuits, tabs,
+sub-devices, the entity ids a dashboard renders from -- and its readers are
+dashboards. This one reports what the panel publishes that nobody has modelled
+yet, and its reader is an editor: every row carries the choices the user may
+assert, computed from the wire declaration through Core's own maps, so the card
+never offers an option the curate command would refuse.
+
+**Nothing here writes registry state, and that is a boundary rather than an
+omission.** Enabling, naming, icons, areas and display units are registry acts
+the user makes through Core's own websocket commands, which already ask for
+admin and already carry the undo. This module owns exactly the metadata Core has
+nowhere to put -- a state class, a device class and prominence for an entity
+built from a vendor declaration -- and `curation.py` owns whether an assertion
+is admissible.
+
+This module must not import `websocket.py`: registration runs the other way, so
+the dependency has one direction and no cycle can appear as further commands

Each panel is a separate config entry with its own device ID. To render multiple panels, call `span_panel/panel_topology` once per panel device ID. The response
is scoped to a single panel — circuits, sub-devices, and entity mappings from other panels are never included.
+
+## `span_panel/adopted/list`
+
+Returns every adopted row on a panel, grouped by the device card it renders on. An adopted row is a property the panel publishes that this integration models no
+field for — a whole device nobody has modelled, or a vendor extension on a device it does model — surfaced as a disabled diagnostic entity in plain wire
+vocabulary.
+
+Those entities carry deliberately minimal metadata, because a state class is not declared on the wire and is not derivable from one, and a device class guessed
+off a unit mislabels as often as it helps. The owner of the vendor device is not guessing, so this command is the input to an editor where they can say what the
+integration refuses to infer. Each row therefore carries not only what the wire declares but the choices Core's own maps admit for that declaration, computed
+server-side so a card never offers an option that would be refused on save.
+
+Admin only, like every command here.

+| `entity_id` | string/null | Null when the entity is not in the registry yet |
+| `datatype` | string | The declared Homie datatype |
+| `unit` | string/null | The declared unit, verbatim |
+| `settable` | bool | Whether the panel accepts a write to this property |
+| `name` | string | The entity's name in wire vocabulary |
+| `curation` | object | The stored record, as stored; `{}` when the row has never been curated |
+| `allowed_device_classes` | string[] | Device classes admissible for this platform and unit; empty for a control row |
+| `allowed_state_classes` | string[] | State classes admissible for this row; empty off a numeric sensor |
+| `stale_fields` | string[] | Stored fields the current declaration no longer supports |
+
+`curation` reports what is stored rather than what would be applied. A field named in `stale_fields` is one the wire has outgrown since it was asserted — the
+entity is built without it, and the editor shows it so the user can see their assertion was dropped rather than silently losing it.
+
+A row is listed whether or not its entity exists yet: adopted entities are created disabled, and a vendor extension appears on the setup after its device card
+does. Curation is keyed on the wire address rather than on a registry ID, so a row can be curated before its entity exists.

Subject: [PATCH 235/345] security(rest): ride the pinned CA at runtime, and
fail closed with repairs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Fixes #264. Every REST call site adopted `panel_rest_transport` when the pin
landed — config flow, reauth, repairs, rotate_credentials — except the one
that runs on every startup: the schema fetch inside connect() stayed on
plaintext HTTP with the pin sitting unused in entry.data, which is the
condition the library's transport warning named. The runtime client now
takes the pinned context and the HTTPS port (span-panel-api 3.4.0), so a
pinned entry makes zero plaintext bootstrap calls in steady state.
Failing closed follows the library's own escalation rule: a matching
fingerprint never convicts. A rotated CA — diagnosed by re-reading the
advertised CA, plaintext deliberately — is the one terminal outcome, taking
the existing guided re-pin repair. Under an unchanged CA the leaf probe
splits the rest: a moved panel raises the existing address repair and keeps
its promise to retry; a leaf the pin does not validate — a middlebox, or a
certificate a clock reset pushed outside its window — raises its own
non-persistent repair and retries, so the clock case heals itself and
plaintext is never fallen back to; missing evidence just retries. The two
same-fingerprint repairs supersede each other, since a panel cannot be both
moved and intercepted.
A stored anchor that cannot be read stops setup with a fixable repair that
reuses the CA-change flow, instead of quietly downgrading the one call that
runs unattended on every boot. A stored HTTPS port of 80 — which the library
refuses under a context — ends in a clear error naming Reconfigure, and both
port forms now refuse it at input.
For the population the deferred pin serves — TLS behind NAT, a port forward,
a proxy, never asked for a port by the gated CA step — Reconfigure now
offers the HTTPS port on any pinned entry, probing against and persisting
the submitted value, and the retry message for an unreachable pinned panel
names the expected port and the remedy. Entry removal clears the whole CA
repair family, including two pre-existing leakers.

+## [2.1.1]
+
+### Fixed
+
+- **The startup warning that panel traffic is unencrypted is resolved, not silenced** — a pinned entry now reads the panel's schema over HTTPS verified against its pinned certificate authority, instead of plaintext HTTP (#264).
+
+### Added
+
+- **A repair when the HTTPS port serves a certificate the pin does not validate** — a wrong HTTPS port, a proxy terminating TLS in front of the panel, or a panel whose clock reset in an outage; the integration keeps retrying without connecting and never falls back to plaintext, so the clock case heals on its own.
+- **A repair when the stored certificate authority can no longer be read**, guiding you through re-acquiring and confirming the panel's certificate authority.
+- **Reconfigure now offers the HTTPS port on any panel with a pinned certificate authority**, for installs whose TLS lives behind a proxy or port forward and were never asked.
+
+### Changed
+
+- **A panel whose certificate authority rotated is now also detected at startup's first read**, raising the same guided re-pin repair it already had.
+- **A moved panel detected at startup's first read raises the existing address repair and keeps retrying**, exactly as it promises.
+- **When a pinned panel cannot be reached at all, the retry message names the HTTPS port and the Reconfigure remedy** instead of only reporting the panel as not ready.

+"""The runtime client rides the pinned transport, and refuses to ride without it.
+
+Issue #264: every other REST call site adopted `panel_rest_transport` when the
+pin landed — config flow, reauth, repairs, `rotate_credentials` — and the one
+that runs on every startup did not. The schema fetch inside `connect()` stayed
+on plaintext HTTP with the pin sitting unused in `entry.data`, which is exactly
+the condition the library's transport warning names.
+
+Fail closed, both ways it can fail. A stored anchor that cannot be read is not
+downgraded to plaintext at the one call that runs unattended on every boot; a
+certificate the pin rejects is not retried into submission. Each gets a Repair,
+because both need a person: the first needs a new anchor accepted, the second is
+either a legitimately rotated CA (accept it) or something standing in front of
+the panel's TLS port (investigate it) — and which of those it is gets diagnosed
+the same way the library diagnoses the MQTT side, by re-reading the advertised
+CA and comparing fingerprints.

Subject: [PATCH 236/345] fix(deps): pair pytest-homeassistant-custom-component
with the pinned Home Assistant
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Each release of the test harness pins one exact Home Assistant, so its pin
and the homeassistant pin are a single choice — the pyproject says so. The
bump to 0.13.358 paired with 2026.9.0b0 against the pinned 2026.8.3, an
unresolvable pair that CI's re-lock from PyPI reports as a sqlalchemy split
(2.0.52 vs 2.0.51) while a stale local venv resolves nothing and notices
nothing. 0.13.357 is the release that pins 2026.8.3.

+Stores the metadata a user asserts for one adopted row, or clears it. The `key` is one `adopted/list` reported: the rows this command accepts are derived the
+same way and from the same snapshot, so a key that command did not offer is refused rather than stored.
+
+**This command writes no registry state.** Enabling an entity, renaming it, giving it an icon or an area, and choosing a display unit are all Core's own
+websocket commands, which already ask for admin and already carry the undo. What is here is only what Core has nowhere to put — a state class, a device class,
+and prominence for an entity built from a vendor declaration.
+
+A successful save has three effects and no others: the record is written to the integration's own store, the config entry is scheduled for reload, and the
+result is returned. The reload is not incidental. An entity description is fixed when the entity is constructed, so a record reaches its entity only by that
+entity being built again — and being built _with_ it, since a state class that first appears after states have been recorded is a statistics reset rather than a
+metadata change.
+
+Admin only, like every command here.

+| `device_id` | string | The device registry ID for the **main SPAN panel**, the same handle `panel_topology` takes |
+| `key` | string | The `key` of the row being curated, exactly as `adopted/list` reported it |

+| Field | Type | Description |
+| ----------------- | ------ | -------------------------------------------------------------------------------------- |

+| `device_class` | string | A sensor or binary-sensor device class the row's platform and declared unit admit |
+| `entity_category` | string | `none`, the one storable value — it promotes the entity out of the diagnostic category |
+
+`record` replaces the stored record rather than merging into it: a field left out is a field cleared. The values admissible for a given row are exactly the
+`allowed_state_classes` and `allowed_device_classes` that `adopted/list` reported for it, so a card built from that response never offers a value this command
+refuses.
+
+### Response

+
+#### Warnings
+
+| Code | Description |
+| -------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------- |
+| `statistics_removed` | The cleared record carried a state class, so long-term statistics stop being compiled and HA raises its own `state_class_removed` repair |
+| `total_increasing` | The recorder reads a drop of more than a tenth as a meter reset and starts a new cycle, so a reading that legitimately falls manufactures consumption |
+
+Warnings are never refusals. They name effects the stored record does not show on its face, because both are about the recorder rather than about the entity.
+
+### Errors
+
+| Code | Description |
+| -------------------------- | ------------------------------------------------------------------------------------- |
+| device_not_found | The device_id does not exist in HA |
+| not_span_panel | The device is not a SPAN Panel device |

+| not_loaded | The integration or config entry is not loaded |
+| no_data | The coordinator has no panel data yet |
+| unknown_key | No curatable row on this panel carries that key |
+| invalid_state_class | A state class was asserted on a row that is not a numeric sensor |
+| invalid_device_class | The value is not a device class for this row's platform |
+| incompatible_device_class | The device class does not admit the unit the row declares |
+| invalid_field_for_platform | A control row accepts prominence only, not a state class or a device class |
+| invalid_format | The request failed the command schema — an unknown value or field, or a malformed key |
+
+The first five are the codes `adopted/list` answers, from the same resolution: a consumer that learned them for one command does not meet a second set on the
+next.

Subject: [PATCH 243/345] docs: curation of adopted entities
developer.md gains a Curation section covering the .storage overlay and its
scope-prefixed keys, validation refusing at save and dropping at construction,
the description helpers that keep both AST guards absolute, the two websocket
commands' zero-registry-writes boundary, and why the reload is the mechanism
rather than a courtesy. The revisable-vs-not table's state_class row moves from
"never set at all" to user-curated only, and the diagnostics section gains the
adopted_curation block's withholding rule.
README.md documents the Adopted tab: what the integration sets versus what is
Home Assistant's own, that saving reloads, the total_increasing and
statistics-class-removal consequences, and that identity never changes.

+is what turns it into something with a real name, a proper category and statistics out of the box.
+
+### The Adopted Tab
+
+The integration will not guess what an adopted reading means. You are not guessing — it is your device — so the built-in dashboard has an **Adopted** tab where
+you can tell the integration what it refuses to infer. It lists every adopted entity on your panel, grouped by the device it belongs to, and expands each one
+into a small form. The tab appears only for administrator accounts.
+
+Three of those fields are the integration's own, and they are the ones Home Assistant has nowhere to put for an entity built from a vendor declaration:
+
+- **Device class** — what kind of quantity this is (power, temperature, energy), which gives the entity a sensible icon and, for the classes Home Assistant
+ knows how to convert, lets you pick a display unit.
+- **Statistics class** — Home Assistant's `state_class`, which is what enrolls the reading in long-term statistics and makes it usable on an Energy dashboard or
+ in a long-range history graph. This is the piece nothing else in Home Assistant can set for you.
+- **Prominence** — whether the entity stays filed under Diagnostics or is promoted out of it.
+
+The rest of the form — **name, icon, area, and whether the entity is enabled** — is Home Assistant's own entity settings, shown here so you do not have to go
+somewhere else, and saved into Home Assistant's registry exactly as if you had edited the entity directly. The integration never changes any of it on your
+behalf; enabling an adopted entity is always something you do.
+
+You are only offered choices your panel's own declaration allows. A statistics class is offered only on numeric readings; the device classes listed are the ones
+compatible with the unit your panel publishes, and the unit itself stays whatever the publisher sends.
+
+**Saving reloads the integration.** That is not a formality — it is how the setting takes effect. An entity's type information is fixed at the moment the entity
+is built, so the reload is what rebuilds it already carrying what you asserted, rather than attaching a statistics class to an entity that has been recording
+without one — which Home Assistant reads as its statistics starting over rather than as a change of metadata.
+
+Two consequences are worth knowing before you use the statistics class:
+
+- **`total_increasing` tells Home Assistant the reading is a meter that only counts up.** The recorder treats a drop of more than a tenth as the meter being
+ reset and starts a new cycle, so choosing it for a reading that legitimately falls will manufacture consumption that never happened. Choose it only for a
+ genuine lifetime total.
+- **Removing a statistics class stops statistics, and Home Assistant will say so.** If an entity already has statistics and then loses its statistics class,
+ Home Assistant raises a repair notice against it — a warning rather than something with a fix button — and stops compiling new statistics for it. The
+ statistics already collected are not deleted, and the notice clears by itself if you put a statistics class back.
+
+**Nothing about the entity's identity changes.** It keeps the same entity id, the same unique id and the same history, so dashboards and automations pointing at
+it keep working. Statistics simply begin from the point the entity is enabled and writing states with a statistics class; the history it recorded before that
+stays as ordinary state history.

+## Curation: metadata the user asserts
+
+Adoption's refusal was never "adopted entities may not have statistics" — it was "the integration will not guess", and those are the same rule only while nobody
+who does know the answer has anywhere to say it. `curation.py` is that place. It owns three fields and no others: `state_class`, `device_class`, and promotion
+out of `EntityCategory.DIAGNOSTIC`. Everything else a user might want to change about an adopted entity — its name, icon, area, display unit, precision, and
+whether it is enabled at all — is registry state Core already owns, and this integration writes none of it.
+
+Identity is untouched in every case. A curated row keeps its `unique_id`, its `entity_id` and its platform: the overlay changes what an entity declares, never
+what it is. That is what makes this safe to apply to entities whose ids are [permanent by design](#terminal-identity) — it is metadata handed to an existing
+identity, not a second identity namespace.
+
+### The store is an overlay keyed by wire address
+
+`helpers.storage.Store` at `span_panel.curation.{entry_id}`, one per config entry for the same reason `additions.py` has one: two panels in one house curate
+independently. The stored shape is `{"records": {key: {field: value}}}`, and a record holds only what the user asserted — a missing field means the adopted
+default, and a missing key means the row was never curated at all.
+
+The keys are scope-prefixed wire addresses rather than `unique_id`s:
+
+| Half | Curation key | Built by |
+| ----------------------------------- | -------------------------------- | ------------------------ |
+| Vendor reading on a modelled device | `{scope}/{node}/{property}` | `extension_curation_key` |
+| Entity on an adopted device | `{identifier}/{node}/{property}` | `adopted_curation_key` |
+
+The prefix is what makes a key injective: `path` is `{node}/{property}` on both models and is unique only within one device. The two namespaces cannot collide,
+because only an adopted identifier carries the `_adopted_` token. Neither key goes through `get_user_friendly_suffix`, which is what makes `adopted_unique_id`
+[deliberately non-injective](#the-device-level-grammar-is-not-injective-and-the-collision-is-caught) — keying the store on a `unique_id` would have inherited
+that collision and let one record reach two wire addresses.
+
+**A record asserting nothing clears its key rather than being stored.** Its stored form is `{}`, which `parse_record` refuses, so writing it would leave a
+record on disk that the next load reports as unreadable — the warning meant for a damaged or hand-edited store — and the save after that would delete, over a
+value the signature accepts. Save may not write what load rejects.
+
+Records are never pruned. One whose wire path stops being published goes inert rather than being deleted, which is the same "the integration never decides a
+row's fate" stance the rest of adoption takes. The whole store does go when the config entry is removed (`async_forget_curation`), and that one is deliberate:
+the keys are wire addresses rather than registry ids, so a store left behind is one the next entry for the same panel would load and apply, re-asserting
+metadata the user removed the panel to be rid of.
+
+### Validation refuses at save, and runs again at construction
+
+`validate_record` refuses rather than warns, because a stored record is applied unattended at every future setup — a warning would be read once, by nobody.
+Everything decidable without the wire is decided in the websocket schema instead (enum membership, the one storable `entity_category`, the key's charset), so
+only cross-field questions reach the validator: a `state_class` needs a sensor row with a numeric datatype, a `device_class` must belong to its platform's enum
+and must admit the unit the row declares (through Core's own `DEVICE_CLASS_UNITS`), and a control row accepts prominence and nothing else.
+
+The same validator runs again at construction, where it drops rather than refuses. A record can go stale between the save and a later setup — the vendor may
+change a row's unit or datatype — so `sanitise` re-measures each field independently, keeps the ones that still validate, and `CurationOverlay.for_row` emits
+one warning naming what it dropped. It never raises: curation must not be able to block setup. It never deletes either, because the wire may revert and the
+user's other assertions are still good.
+
+That is also why the list command reports a record **as stored** rather than as it would be applied, beside a `stale_fields` list naming the difference.
+Reporting the sanitised form would show the user an assertion they never made and hide that theirs was dropped.
+
+### The description helpers are the only place `state_class` is spelled
+
+`adoption.py` and `extension.py` each carry an AST guard asserting the token appears nowhere in them — not as a keyword, not as an `_attr_state_class` target,
+not as a `SensorStateClass` name. Both stay true while their entities carry curated state classes, because neither module builds its own description: both call
+`curation.sensor_description`, which takes the wire path, the declared unit, the `DEVICE_CLASS_BY_UNIT` default and the record, and returns the
+`SensorEntityDescription` the entity is constructed from. `binary_sensor_device_class` and `entity_category_for` do the same job for the other two fields.
+
+This ends up stricter than the design asked for. The plan was to relax the adoption guard into "the keyword is permitted when its value comes from the curation
+interface"; routing through a helper meant it did not have to relax at all, and the guard newly added for `extension.py` could be the same absolute form rather
+than a weaker one. A guard that admits one shape of exception is a guard somebody has to re-read before trusting.
+
+### The two commands write no registry state
+
+`websocket_adopted.py` defines `span_panel/adopted/list` and `span_panel/adopted/curate`, and `websocket.py`'s `async_register_commands` registers them beside
+`panel_topology` — the import runs that way and only that way, so no cycle can appear as further commands join. Both are `@require_admin`, both take the main
+panel's device registry id, and both answer `panel_topology`'s error codes from the same resolution — a consumer that learned one set does not meet a second.
+[websocket-api.md](websocket-api.md) is the wire contract; what matters here is the boundary.
+
+**Enabling is Core's act, and so are naming, icons, areas, display units and precision.** `config/entity_registry/update` already exposes all of them, already
+requires admin and already carries the undo, so duplicating any of it here would mean two writers for one field and no rule about which wins. What is left over
+is exactly what Core has nowhere to put — a state class, a device class and prominence for an entity built from a vendor declaration — and that is the whole of
+what `curate` stores. `entity_category` is the interesting one: it _is_ a registry column, but it is absent from that websocket's schema, which is why promotion
+has to come from us.
+
+Both commands derive their rows through one function, `_rows`, using the same helpers the entity builders use — `resolve_identifier` and `classify` for an
+adopted device, `adoptable` and `resolve_platform` for a vendor reading. A second derivation would let the editor disagree with the entities it edits: offering
+a state class for a row that is really a control, or a key `curate` cannot resolve. `curate` re-derives rather than trusting the key it was handed, because the
+store is keyed on wire addresses and a key nothing publishes would be held forever — read by no entity and shown on no list.
+
+`_rows` inherits the adopted-device collision rule as a **skip** rather than a listing. A row whose `unique_id` was claimed by a lexically earlier wire path is
+left out entirely, because `entity_id` resolves by (platform, `unique_id`): listing it would report the _winner's_ entity beside the loser's curation key,
+inviting a record saved against an entity that will never read it under a live `entity_id` saying it will. `_create` already warns and names both addresses, so
+the skip is silent.
+
+### The reload is the mechanism, not a courtesy
+
+A save has exactly three effects: the record is written, the entry is scheduled for reload, and the result is returned. The reload is the half that reads as
+politeness and is not. An entity description is fixed when the entity is constructed, so a record reaches its entity only by that entity being built again — and
+being built _with_ it, because a `state_class` that first appears after states have been recorded is a statistics reset rather than a metadata change.
+
+The response also carries advisory `warnings`, which are consequences of a save rather than objections to it: the write has already happened, and the user asked
+for it. `statistics_removed` fires on what a save _leaves_ rather than on how it was spelled — a record narrowed to its other fields drops a state class exactly
+as clearing the whole record does — and names Core's answer to that, which is to raise its `state_class_removed` repair and stop compiling statistics for the
+entity. Statistics already collected are not deleted. `total_increasing` is the other warning, and it reinterprets a reading rather than describing it:
+`sensor/recorder.py`'s `reset_detected` reads a drop of more than a tenth as a meter reset, so a reading that legitimately falls manufactures consumption.

Subject: [PATCH 244/345] security(discovery): probe a pinned entry's
configured host over its pin
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The Supervisor-discovery host check reads the serial that decides whether
the entry moves, and it read it over plaintext with the entry's anchor
sitting unused — the one probe of a configured host that did not ride the
pin. Since span-panel-api 3.4.1 exempts the status endpoint from the
plaintext warning, nothing in the log would say so either; the probe now
takes the entry's own transport, on the add-on's newly published TLS port
when it published one, because a reallocated port is the very case this
probe exists for. Unpinned entries keep the plaintext probe they always
had. (Direct checks run in lieu of the worktree-incompatible uv hooks:
pytest 1676 passed, ruff, mypy all clean.)
