ARCHITECTURE.md:492 counted five files under server/engine/ while the
directory has shipped six since #143. The missing one is
providers/local-runtime-v2.capabilities.js, the declaration-only module
whose sole import is ../capabilities.js — the split that keeps the v2
host's ~4.7 s TypeScript dependency tree off the boot path. The
local-runtime-v2.js row credited itself with the declaration it only
re-exports, so that credit moves to the file that actually defines it.

The zh-CN mirror takes the same edit in the same commit (equal weight);
check-docs-alignment.mjs resolves the new bare-path citation against the
merged tree.
…ine-abstraction M2)

Baseline: feat/engine-capabilities (M1, PR #143), NOT main — the
server/lib/engine -> server/engine path fix has not landed yet.

- test/lib/engine/capability-snapshot.test.js boots ONE real catalogue
  host on an isolated tmp data dir (MINIMAX_DATA_DIR + every
  MCODE_WEBUI_* path pinned before the provider import) and audits
  every full/partial key of both providers against the reflected
  surfaces: full requires every tracked method (REQUIRED_METHODS,
  derived from the live prototype chains — 91 adapter / 94 CliService
  methods — not copied from the design matrix); partial requires the
  present half to exist, method-named missing items to be genuinely
  absent (under-declaration goes red), and kebab-case sub-capability
  names to have no covering method; none is not method-checked.
- Mutation tests pin the checker itself: flipped level / deleted
  method / grown sub-capability each go red (also verified by hand:
  three file mutations red at exit 1, restored byte-identical).
- Registry-driven static guard: every registered provider declares
  exactly ENGINE_CAPABILITY_KEYS — typo keys cannot pass silently, and
  M4 providers are swept without editing the test.
- Docs: ARCHITECTURE.md/.zh-CN.md M2 section, webui.md/.zh-CN.md
  migration-state entry; tmp prefix registered in the leak gate.
… path

The M1 path move took server/lib/engine to server/engine. This file was
written against the old one and rebase carried the code forward without
carrying the import, so the suite failed on MODULE_NOT_FOUND and said
nothing about the capabilities it was meant to check.
…ther

Three leaks, all from state that lived outside the component that
should have owned it.

page.tsx read localStorage during render, so the pre-rendered HTML and
the first client frame could not agree — a skeleton screen was hiding it,
which is exactly the kind of cover that disappears the moment someone
edits the shell. The first frame now uses defaults and one mount effect
restores; the three write-back mirrors are gated so a default never
overwrites a stored value. Scroll position is read by the same sessionKey
effect Chat already had, which reads the same key.

The draft store was a module-level bucket, so a draft, a failure banner
and a model chip all followed you across sessions — type into one
conversation, switch, and your words are in the other. The store is
keyed by session now. Isolation is not discarding: switching back finds
the draft still there. Clearing was the alternative and it destroys an
unread banner every time you return to a conversation.

#126 left the accepted-but-unconfirmed banner without anything to
consume it when a turn ended. unconfirmedPatchOnTurnEnd clears it on the
falling edge of running, and only there — the three-value decision about
when to show it is untouched.
…the engine facade

Migration step M3, batch B0 (engine-abstraction). 13 endpoints across
routes/plugins.js and routes/turn-diff.js reached the catalogue host by
importing lib/acp-client.js#getCatalogueHost directly. They now call
getEngineCatalogueHost() from the facade.

- engine/host.js: the lazy bridge. Its only import is a dynamic
  `await import("../lib/acp-client.js")` inside the function body, so
  engine/index.js gains a function and not a module load. That boundary
  is the whole point: app.js reaches engine/index.js through
  routes/engine-capabilities.js, and a static import of acp-client there
  would put the ACP client tree on every server start — the regression
  M1 paid for once (209ms -> 2700ms; facade load 4685ms -> 5ms once
  declaration and construction were split). The value is forwarded
  verbatim, `null` included, so "host did not boot" stays
  RUNTIME_UNAVAILABLE and never a second host.
- engine/index.js re-exports the getter; the two routes import it from
  there and no longer name acp-client.js.
- No endpoint behaviour changes: same wire shapes, statuses, codes, same
  `deps.getCliService` / `deps.getDiffApplication` seams, same one
  process-wide host. Measured on the module graph: routes/plugins.js
  drops from 13 product files + @mavis/shared to 8 files and zero bare
  packages; engine/index.js's whole closure is 6 files and 0 bare
  specifiers. Server start and the facade's own load are unchanged
  (facade ~1.2ms -> ~3ms, i.e. one more 45-line zero-import file; boot
  stays in the same 200-300ms band) because lib/state-bus.js already
  pulls acp-client into app.js's boot graph — closing that edge belongs
  to the catalogue read/write batches (M3-B1+), not here.

Tests: test/lib/engine/host-facade.test.js pins the contract against the
real module graph rather than against source text — a resolve hook
(module.registerHooks) in a fresh process reports, per parent, which
specifiers each entry resolved. It asserts neither route has a direct
edge to acp-client/runtime-host/acp.mjs, that loading engine/index.js
pulls no host module and no @mavis/* or @minimax/* package, that
engine/host.js is in that closure, and the source-shape tripwires
(dynamic import only, facade re-export). Mutation-checked: making the
facade import statically turns 4 tests red, making plugins.js import
directly turns 4 more red. The existing plugins/turn-diff suites pass
unchanged under both transports (158 tests x acp and x runtime).

Docs: ARCHITECTURE.md + .zh-CN.md — the engine/ file table gains
engine/host.js on top of the six files #143 + the doc batch settled, the
"one host" rule now names the facade, and the boot-path discipline is
stated where the file list lives. docs/webui.md + .zh-CN.md are
untouched: no user-visible change. Source inventory regenerated for the
two new files (rebase conflict in it was resolved by taking the upstream
copy and regenerating, never by hand).
…ites immune to the gate's isolation env

The webui gate runs with MCODE_WEBUI_DATA_DIR, MCODE_WEBUI_SETTINGS_PATH and
MINIMAX_DATA_DIR exported at a scratch directory. Two suites read paths those
exports take away from them:

- config.js#resolveDataDir reads MINIMAX_DATA_DIR ?? MAVIS_DATA_DIR, so the
  gate's MINIMAX_DATA_DIR outranked mavis-usage.check.mjs's own MAVIS_DATA_DIR
  fixture and every DB-backed case resolved null against a scratch dir that
  holds no runtime-state.sqlite. The suite now exports the name that wins.
- config.js resolves SESSIONS_DB as MCODE_WEBUI_SESSIONS_DB ||
  join(WEBUI_DATA_DIR, "sessions.json"). A caller that exports
  MCODE_WEBUI_SESSIONS_DB redirects the store, while the suite's beforeEach
  still cleared join(DATA_DIR, "sessions.json") — so each run read the
  previous run's records and the mid-run switch resolved an id whose
  workspace belonged to a since-removed tmp dir. Both chat-route suites now
  pin MCODE_WEBUI_SESSIONS_DB to the same path their cleanup clears.

Test-only: no server/ code, no helper under test/helpers/_setup.js, and no
assertion weakened or skipped. Verified with the three variables set, with
MCODE_WEBUI_SESSIONS_DB additionally set, and bare.

…ransport (M3-B1)

The directory-read family — #9 acp-sessions, #10 acp-session-title, #72
protocol/list-sessions, #74 state, #75 health — reached the engine through
whatever MCODE_WEBUI_TRANSPORT happened to be, so "does the engine support
this" had no answer anywhere except the absence of a crash. server/engine/
session-reads.js gives it one: each endpoint declares the capability and the
provider method it needs, the facade checks the registered provider's
declaration first, and a provider that does not offer the read answers 501
through invokeHandler instead of an empty list.

Nothing on the wire moves. The facade forwards to the same acp-client
exports the routes already called, so the 30s cache, the cwd normalisation,
the 30s-stale sidebar push semantics and the catalogue-sessions projection
are the same code; handleHealth becomes async because the version now
resolves through the facade, which is why app-hono's legacy-parity helper
learned to await it. /api/state's snapshot field list is untouched —
snapshotViewFields and mcodeSessionsSnapshotFields are the first-frame render
contract and this batch adds and removes nothing.

Each read also reports where its bytes came from — catalogue, acp, or
acp-fallback when the runtime transport asked for a host that never booted.
That is metadata, not wire, and it is the difference between a sidebar that
degraded and one that pretends.

Two things this batch found rather than assumed: the catalogue host exposes
no version accessor, so /api/health keeps answering from the ACP initialize
mirror and says so rather than inventing a method; and protocol.js#72's old
test drove a mock key nothing read, so "the cwd filter works" had never
actually been proven.
…ade (M3-B2)

Routes #8 GET /api/session-tree and #11 GET /api/sessions/:id/export
through the engine facade instead of the transport, keeping every
response shape, status code and reason string unchanged.

The two families are separate files because their gate policies are
opposite. The tree is entirely engine data, so a provider that cannot
list sessions genuinely has no tree: assertSessionTreeCapability throws
and invokeHandler answers 501. Export's primary source is sessions.json
and the engine only contributes a best-effort transcript enrichment the
endpoint has always promised never to block on, so
checkSessionExportCapability reports and never throws — gating it hard
would delete working functionality in response to a declaration about a
capability the endpoint does not depend on. The tree route re-throws the
capability error, matched with the class's own instanceof helper rather
than a `.name` compare: `name` is a writable instance property, so a
stray `err.name = "…"` would silently turn that 501 back into the 200
soft-fail the gate exists to prevent. A test pins both halves — the real
class propagates, an impostor carrying the right `.name` does not.

Verified by exporting the real tree (303 rows, 32 projects, 299 nodes)
before and after and diffing every node's id/title/parent/depth: 3289
field comparisons, zero differences. A synthetic fixture covers what the
live data does not contain (orphans, cycles, four-level nesting, exotic
titles): 165 comparisons, zero differences. Two pre-existing shapes are
pinned because a "cleanup" would silently break them — child nodes carry
no `children` key (all 66 of them), and the response has no
parent_session_id key at all.
…acade (M3-B4)

#20 /api/account, #57 /api/models and #73 /api/protocol/capabilities now reach
the engine through three new engine/ modules instead of naming lib/mcode-rpc.js,
lib/models.js, lib/providers-config.js, lib/engine-catalogue.js and
lib/acp-client.js themselves.

Three modules because the three gate policies are all different: the account
read gates HARD on authCredentials.getAccountStatus (the same provider method
B3's #15/#16 read, so a provider that drops it takes both down together), the
model catalogue gates SOFT (its primary sources are files webui owns, so a hard
gate would delete a working picker), and #73 declares nothing at all because it
IS the declaration endpoint.

The model projection moved whole — three sources, the per-provider dedupe, both
builtin-tree annotations and the three derived figures are now named pure
functions pinned on their inputs, and #57 is verified by a full snapshot whose
oracle was captured from the pre-refactor implementation. Its read stays
synchronous so handleGetModels keeps its contract, which is also why
engine/model-reads.js is not re-exported from engine/index.js: its four sources
reach @mavis/shared and js-yaml, and the boot-path guard is right to refuse
that under the shared facade.

#73 is the one response body in the migration that changes: it gains an
`engine` key carrying the engine-capabilities view, with `providerFor` saying
whether the declaration came from the active transport's provider or from the
default one standing in. Every pre-existing key keeps its name, position and
value, and the ACP wire table is not replaced by the 14 matrix keys.
…ilities view (user-approved contract change)

`GET /api/protocol/capabilities` used to answer from two hand-maintained
places: `MCODE_ACP_CAPABILITIES`, a flat `{method: boolean}` table of the
ACP JSON-RPC surface, and the `initialize` agentInfo mirror. The engine's
DECLARED capability surface already existed — the 14-key per-provider
object that `GET /api/engine-capabilities` serves — so webui was carrying
two parallel answers to "what can this engine do", able to disagree, with
no test able to notice. This makes `capabilities` the declared object and
drops the wire table from the endpoint.

This is a reviewed, user-authorised endpoint contract change, not a refactor
side effect, and it is stated as such in the module header, in
`docs/API.md` and in both ARCHITECTURE twins. The twelve old accessors are
asserted GONE, so a consumer reading `capabilities.set_mode` gets
undefined and fails loudly rather than receiving a truthy object field.
No runtime consumer exists: nothing in `webapp/` reads this endpoint, and
`engine/capability-reads.js` no longer imports `lib/mcode-rpc.js` at all
(pinned by a static tripwire, because an unused import is behaviourally
inert and no behavioural test could see it).

The `engine` key the previous commit added is REMOVED rather than kept:
with `capabilities` already the declaration, an `engine` block would carry
the same 14 keys a second time in one response. What survives from that
shape is the provenance — `capabilitiesProvider` / `capabilitiesProviderFor`,
the honest bit that says whether the declaration came from the active
transport's provider or from the default one standing in — plus
`capabilitiesUnavailable` for the derived degradation roll-up. A test
counts the declaration's occurrences in the serialised body and requires
exactly one, so a second carrier is a red bar.

`MCODE_ACP_CAPABILITIES` is kept and stays pinned by
`test/lib/mcode-rpc.check.mjs`: it is still a true statement about the
ENGINE's ACP surface and `docs/CAPABILITIES.md` cites it as one. It has no
webui consumer left, recorded as debt in the module header rather than
deleted as a side effect.

`docs/webui.md` and `docs/webui.zh-CN.md` gain a diff here for the first
time in this migration: they carried the old response shape in their
endpoint tables, and an authorised contract change has to be documented
where the contract is written.
…ger has

Found by the dual-axis code review (Standards + Spec) before B4 merges. No
logic changes; both were documentation lying about the code next to it.

`engine/index.js` still described #73 as an additive change — "the response
body gains a key (`engine`, the engine-capabilities view) … additive rather
than a replacement". The second B4 commit made it a REPLACEMENT and deleted
the `engine` key, so the facade's own export table was the one place still
telling a reader the opposite of what the endpoint does. It now states the
replacement, why the `engine` key was removed rather than kept, and what
survived from it (the provenance keys and the derived roll-up).

`docs/ARCHITECTURE.md` and its zh-CN twin called `engine/account-reads.js`'s
read **synchronous**. It is `async` — `readEngineAccount` awaits a
`Promise.all` of dynamic imports — and the boot-path note the row pointed at
describes model-reads, not this module. The same two documents already
listed account-reads correctly under the `await import()` rule a few
paragraphs down, so the file contradicted itself in two languages at once.
Both rows now say asynchronous and point at the ordinary rule.

Also drops a dead `assertEngineCapability` import from
`engine/model-reads.js`: the soft gate inspects the declaration inline, so
the throwing helper was never called and its presence read as if the soft
path could still throw. Replaced by a comment saying why it is absent, so
the next reader does not "fix" it back in. And the one comment with Chinese
embedded mid-sentence (仓库 review 要求注释用英文) is now English; the header
parentheticals naming each family (账户读 / 模型目录读 / 能力声明读) stay, as
do the quoted product strings — `本地用户` is the real zh-CN value of
`userMenu.localUser` and `shell.tsx` cites it the same way.
M3 batch B5: #7 DELETE /api/sessions/:id, #4 POST /api/sessions/rename and
#6 POST /api/sessions/cleanup-orphans stop driving the store, the caches
and the engine's own local_runtime_* tables from the route. They ask
engine/session-writes.js instead, so the load -> resolve -> authorize ->
intent-audit -> mutate ordering — and the resurrection guard inside it —
becomes named, testable code rather than a two-line helper a route could
call out of order.

#7 and #6 gate HARD on sessionCrud.deleteSession, because the rows they
destroy are the engine's own; #4 declares no capability at all, because a
rename writes webui's own store and touches no engine surface. The policy
is decided by who owns the rows the write destroys, which is a different
question from the read families' and does not have the same answer twice
in a row here.

The facade exposes a plan/commit pair rather than one deleteSession(),
so the write-ahead audit still lands between "know what the user asked to
delete" and "delete it". Response bodies are built in the facade once,
which is what lets the #6 and #7 dryRun shapes be pinned byte-for-byte by
unit tests. No status code, response body or error code changes.

The 32-table delete SQL stays in lib/mcode-session-delete.js and is
reached by dynamic import; acp-client.js and four test files bind to that
specifier, so collecting it is a later batch's job. Recorded as KNOWN
DEBT, along with rename writing a webui-side label only, and delete not
detecting an in-flight session.
…rfaces

The authorize-button fix (08599472) surfaced five more primary surfaces
pairing text-text_default_inverted_static with bg_interaction_primary_default;
dark mode inverts that background to pure white while the token stays
near-white, so the label composites to white-on-white. Swap all of them to
text-text_label_primary_default and add a source-scan guardrail that keeps
the pairing out of primary surfaces while pinning the sanctioned status-badge
exception (toolbar).
M3-B6: #3 POST /api/sessions/switch now asks the engine facade instead of
reaching into lib/acp-client.js, lib/transcript.js, lib/mavis-usage.js,
lib/models.js and lib/config.js from the route.

The new engine/session-switch.js owns the four load-bearing facts the
~290-line handler had accumulated: the mvs-sid-first resolution order
(single base-session identity), the backfill decision and its read, the
workspace containment gate (which runs before any cs mutation, so a
refused switch leaves the client untouched), and the response body.

The gate is SOFT — it reports and never throws — because the switch's
primary data is webui's own record and both engine touches have a
defined degradation. Gating hard would remove a working endpoint over a
title and a transcript, and would do it on the default acp transport
first.

The route keeps what is its own: the "id required" 400, the status
mapping, the fail-closed audit and the SSE push — the audit has to land
after the switch has already mutated cs, and the push must not fire when
it fails.

Behaviour is unchanged and pinned: the four red lines (transcript
backfill, cumulative detection, workspace containment, single base
session identity) each get named tests with their negative half, and the
success body's key ORDER is compared as a string. Six mutations of the
facade were run to prove the tests are load-bearing.

KNOWN DEBT 1 in the new module records what this batch did NOT retire:
the 3-candidate transcript probe. The default acp transport has no
engine surface to replace it with, getMessages paginates where the probe
caps lines, their orderings differ, and export's enrichment is still
byte-pinned to the same candidates. What IS retired is the coupling —
the route no longer names lib/transcript.js, and the probe list is an
implementation detail behind one seam.
main's #148 squash is a subset of dev-lhl content (every main blob is an
older revision of a file dev-lhl evolved, verified blob-by-blob against
e595c7c). Resolving toward dev-lhl loses nothing and advances the merge
base past the squash, unblocking PR #149.
gitleaks' generic-api-key rule flags the deliberate sk-secret-should-
never-leak fixture that model-reads.test.js uses as a leak-prevention
tripwire (asserting the facade never serializes provider keys). The
value is fake and the assertion exists to catch real leaks; allowlist
the exact pairing instead of weakening the fixture.
The full-history scan flags two synthetic-credential fixtures: the
model-reads leak tripwire (fake provider keys asserting the facade
never serializes them) and the fs-credential-guard canaries (fake
id_rsa/pem bodies asserting the 403 guard). Pin their fingerprints in
.gitleaksignore; the .gitleaks.toml path allowlist for the same files
stays as a coarse first line.
The match-targeted entry missed the byok fixture key (the generic rule's
match string differs from the tripwire value the entry was written for).
Scope both entries to the two fixture files themselves — every finding
in them is synthetic by construction — and keep .gitleaksignore as the
precise fingerprint layer.
The batch plan transcribed the abort bound as 5s; the migrated file ran
2000ms. The product call (2026-10-03) takes the plan's value: the longer
grace gives a stubborn child more time to finalize at the cost of
'already stopped' staying a lie for three extra seconds. The pinning
test moves with it and KNOWN DEBT 1 records the resolution.
main's #149 squash is the dev-lhl tree at 3f5b8d2; everything since is
gitleaks fixture allowlists plus B7. Resolving toward dev-lhl advances
the merge base past the squash and keeps PR #150 to its real content.
fengzhi09 and others added 23 commits October 3, 2026 17:54
main's #158 squash carries M4-1 (acp provider registration) and P18
(code block overflow); resolving toward dev-lhl advances the merge
base past the squash (SPEC rule 8).
main's #159 squash carries M4-2 (exec provider registry), M4-3a
(deleteSession facade), P17 (svg escape), D1 (exec stream events)
and PB-1 (session context actions); resolving toward dev-lhl
advances the merge base past the squash (SPEC rule 8).

The General page's 上下文窗口用量显示 switch wrote `webui-context-window-usage`
and nothing read it, so flipping it changed nothing on screen. The key now has
a live channel in lib/settings-local.ts — `subscribeContextWindowUsage`, the
same subscribe*/unsubscribe shape lib/theme.ts uses for the appearance picker —
and components/context-meter.tsx reads the flag at mount, follows the channel,
and draws its ring only while the switch is on. Toggling it takes effect in
the already-open page; the composer mount point stays unconditional so there is
one gate, not two that can disagree.

The stored default stays "false", the desktop reference's default, and the
bare "true"/"false" format stays: the key did not move onto the
webui:ui:v1 envelope, which would have broken the reference-shared contract.
What does change is that an untouched profile no longer sees the meter — it
used to draw unconditionally while the switch did nothing.

Also moves the panel's `expanded` hook above the component's early returns;
it was declared after `if (!context || !context.limit) return null;`, which
made a hook conditional on whether a snapshot had arrived.

The item was a placeholder claiming a browser cannot reach the OS file
manager. That was never true — `POST /api/fs/reveal` has been
implemented and registered all along (`server/routes/fs.js#handleFsReveal`,
`server/app.js`), and a webui install is normally the same machine that
holds the workspace. Only the wire was missing.

`webapp/lib/project-reveal.ts` carries the two claims the batch makes, as
injected-transport functions so both are driveable in `node:test` without
a render harness: `projectRevealTarget` resolves the project's path
(first repo root, else first directory — the same rule the 切换目录 row
already used, now sharing one helper), and `runProjectReveal` fires the
request and reports whatever did not work.

The pre-check is the interesting half. `revealInFileManager` RESOLVES
with `{ok: false}` on an HTTP error rather than rejecting, so a
try/catch-only implementation treats every containment refusal and every
missing opener as success and the user watches a menu that did nothing.
The `!result.ok` branch is asserted for that reason.

The row is disabled for exactly one reason now — the project is bound to
no local directory — and the tooltip says so in those words instead of
shrugging with `common.notLocal`. Success is silent (the file-manager
window is the feedback); failure goes to the same banner as the menu's
other writes, labelled with the menu's own localized name.

The SESSION-level reveal stays a placeholder: the desktop reference
disables it too, so there is no parity to chase, and unlocking it would
be a product decision this build has not made. Both menus live in one
file, so the session one is pinned as still-honest.

Tests: `webapp/test/project-reveal.test.ts` (19 cases across behaviour,
bilingual coverage, and menu wiring); the expired reveal half of
`shell-elements-parity.test.ts` is corrected. Six mutations verified red
(dropped path argument, swallowed refusal, re-hard-disabled row, pathless
click, retired tooltip, bypassed pre-check).
The settings page printed ten desktop shortcut rows disabled behind a
「浏览器环境不适用」 notice while app/page.tsx dispatched Ctrl+N and
Ctrl+,. Both statements could not be true, and neither the page nor the
handler owned the truth.

webapp/lib/shortcuts.ts is now the single registry: per row it records
the combination, whether the browser hands that combination to a page at
all, and — when it does not — which of three reasons applies (the
browser owns the combination, the WebUI has no surface, the action's
semantics are undecided). app/page.tsx matches keydowns through it and
the settings page renders it, so the two cannot drift apart.

Unlocked: Ctrl+K (search surface) and Ctrl+Alt+O (new task) join the two
bindings that already worked; the three live rows are rebindable, the
overrides persist under webui-shortcut-bindings and are re-validated
against the registry on read, and a combination another dispatched row
already owns is refused with the conflicting action named. Ctrl+N stays
dispatched but is labelled platform-limited rather than offered as
rebindable, because the browser takes it on Windows and Linux.

The notice now says what each state means, and every blocked row prints
its own reason instead of sharing one blanket denial.
SB-7 — the A1 revision for the Token Plan view. Ticket 53's A1 ruling
("no source, so placeholder") was applied to the whole plan card, but two
sources exist: the plan quota over `POST /api/usage` (already live) and the
plan tier over `GET /api/account`. The card is now split by source instead
of by card.

- `PlanCard` takes the plan name and renders it verbatim; `planNameOf` is a
  pure resolver (a failed account surface, no plan, and a blank tier all
  collapse to null) and there is deliberately no default tier.
- The container fetches `/api/account` on mount, as the user menu's account
  card does, and passes the resolved name down.
- Credits, expiry and invoicing stay placeholders, but the reason is now the
  accurate one — the cloud account domain, which this self-hosted session
  has no credentials for — instead of "not applicable to the local
  edition", which was already false of the plan name above it.
The 「用量与模型」 tab's source switcher, its 「使用中」 badge and the
MiniMax API key row were three `useState` / `disabled` controls under a
comment claiming this repo has no `setMiniMaxModelSource` backend. The
four engine methods behind them have existed the whole time
(local-runtime-v2 `cli-service.ts`: getMiniMaxModelSource,
setMiniMaxModelSource, upsertMiniMaxApiKey, testUserModel) and had no
HTTP window. This adds the window and makes the tab's three claims
true.

Four new endpoints, all over `host.cliService` through the existing
`getEngineCatalogueHost()` facade:

  GET  /api/model-source          the active source + masked key status
  PUT  /api/model-source          switch the source
  PUT  /api/model-source/api-key  upsert the key (absent = keep)
  POST /api/model-source/test     connectivity probe, stored key

The gate is on the LIVE member, not on a declaration: the four methods
hang off the v2 cli-service's own `modelProviders` requirement, which is
not one of the 14 declared capability keys, and adding a 15th for one
batch would restate every provider declaration and the snapshot audit
(PB-1 met the same situation for `pinSession` and resolved it the same
way). No host is 503, a host without the method is 501, and an engine
refusal keeps its own `LocalModelProviderError` status and code.

Four decisions worth stating:

- The keep-key sentinel. The GET can only return a mask and the engine
  rejects a mask submitted as a key, so an absent or empty `apiKey`
  keeps the stored one, calls no engine write, and answers
  `{changed:false}` with the current status. Same convention and same
  empty-string spelling as `PUT /api/providers`.
- Every write answers from a READ BACK, never from the request, so a
  response cannot report a source or a key status the engine does not
  hold.
- A key-status read that is missing or throws degrades to
  `available:false` rather than to `hasKey:false`, which would tell a
  user with a stored key that they have none.
- An error with no engine status becomes a fixed 500 whose body carries
  no engine text: an exception string from an unrecognised thrower is
  the one place a credential could still be echoed.

On the tab: the pill stays the VIEW and the badge is fed only by a
read-back, so a refused switch (the engine's `NO_API_KEY`) leaves the
key field the user needs on screen while the badge keeps showing what is
really in use. The probe reads the STORED key and says so
(`tested:"stored_key"`); the button is disabled while the field holds
an unsaved value, because v2's `testUserModel` takes no key override.

Not in this change: the add-model dialog's 「自动获取」 still resolves
against the built-in preset directory (v2 has no per-provider catalogue
query for an arbitrary key), and the Token Plan cards stay on decision
A1. Both are recorded in the module's KNOWN DEBT.

Verified on an isolated instance (own port, own engine data dir) against
the real v2 runtime: a synthetic key is stored and masked, `saveAndUse`
switches the source in one call, the switch survives a process restart,
and the probe returns a completed 200 with a real 401 status for that
key. Nine mutations were injected and each is killed by the suite.
