Implements the drive state artifact specified in #2187 — an encrypted, signed snapshot of one drive's local rows, published to Arweave so another client can restore the drive without walking its GraphQL history.

Includes #2187. This branch carries the design document as well as the implementation, so the code's section citations resolve for a reviewer. It targets dev rather than the design branch because CodeRabbit reviews are disabled for non-dev bases, and a change this size should not skip review. #2187 can merge first or be closed as superseded — either way the doc lands once.

The spec on this branch is corrected against what was actually built: the operation order is gzip→sign, Content-Encoding must never be set, the payload carries a signed coverage claim, and a known section must be present even when empty. Those corrections are the diff against #2187.

Nothing is published and nothing changes for users. Both paths are behind AppConfig flags that default to false in all three flavours: enableSyncFromDriveState (read) and enableDriveStatePublishing (write). No artifact has ever been posted to any network — every upload collaborator is mocked in tests. The first upload is deliberately a human action.

Trying it

Ctrl+Shift+Q opens dev tools; toggle enableDriveStatePublishing. The item then appears in the New menu for a private drive you own that has files in it. configVersion is deliberately not bumped — the flag ships as false, so a bump would deliver nothing while wiping every user's stored config.

What it does

  • Export one drive's rows — drive, folders, files, all three revision tables, licences — through explicit selectOnly projections. Key material cannot travel: a test reads the generated SQL and fails if a withheld column or a SELECT * appears in it.
  • Seal: gzip → sign as an ANS-104 data item → AES256-GCM under the drive key.
  • Discover by GraphQL, owner-filtered, with "the indexer did not answer" kept distinct from "this drive has no artifact".
  • Import: validate everything before writing anything, then merge in one transaction.
  • Compose into sync as its first source, ahead of snapshots, falling back silently at every failure.

Decisions worth a reviewer's attention

Revisions travel, and every revision does, not just the newest. Entry rows alone restore a drive that renders an empty file listfilesInFolderWithLicenseAndRevisionTransactions INNER JOINs network_transactions through the newest file_revisions row. Measured on a real 42k-file drive: 1.05 revisions per entity, 4.7% with more than one, so full history costs ~5% more rows. This is the one binding call made without a sign-off; it is the superset, so narrowing to latest-only later is a producer-side change needing no reader change.

network_transactions is regenerated on import, never carried. It has no driveId — publishing it would publish rows about the user's other drives to everyone holding this drive's key. The importer derives it through the same helpers sync uses, and marks the rows mined; _asMined argues that trade in full.

Coverage is signed, and the tags are checked against it. Block-Start/Block-End are chosen by whoever posts the transaction and nobody signs them. Re-tagging a genuine artifact with a higher range would advance every importing client's watermark across blocks whose rows it never carried — files silently missing, nothing logged. The claim lives in the payload; a mismatch on either end is refused. The producer reads its watermark and its rows in one transaction, so it cannot tag a range its own payload contradicts.

Content-Encoding: gzip must never be set on this entity, though an earlier draft of the spec said to. ar-io-node indexes it from both L1 transactions and bundled data items and echoes it onto the data response; what the gateway serves is GCM ciphertext, so a browser would try to gunzip ciphertext and fail with ERR_CONTENT_DECODING_FAILED, with no opt-out. Tags are immutable — every artifact published with it would be permanently unfetchable.

A known section must be present even when empty. An absent section and an empty one are indistinguishable on the wire and mean opposite things. A producer built earlier on this branch signs a three-section payload that verifies, counts correctly, and claims honest coverage — and restores a drive whose file list is empty. Unknown sections are still ignored, so additive extension survives.

A sync that skipped entities cannot publish. Sync advances lastBlockHeight regardless of skips, so publishing from that state makes a gap permanent and immutable. Skip state is three-valued: "no sync has run" is not "clean".

What two independent reviews found after the first push

CodeRabbit and an independent QA agent reviewed this separately. Both were worth running: between them they found ten defects that the lanes' own tests, and about eighty mutation checks, had all passed over. The pattern is consistent — the guards we wrote hold, and what got missed was things nobody thought to guard.

  • A ghost folder's children imported unreachable, permanently. The export drops folders with no revision — which is what a ghost folder is — while keeping the files inside them, which do have revisions. Nothing lists a file except by its parent, so those files were invisible, and the import stamped the watermark past the range that would have healed them. Both reviewers found this independently. The consumer now materialises the stand-in the way sync does, so the drive lands in the state the producer is in: a ghost with a Fix button.
  • A second, ungated entry point into the publish flow, predating the feature flag, so the item appeared with publishing switched off. The rail tests all passed — each asserted a property of a function, and none could see a call site nobody handed it. There is now a test that reads the source.
  • syncDeep was short-circuited by the artifact, so the only "start over" remedy the interface offers re-applied the cause.
  • A probe-skipped drive read as "clean" for the publish precondition, though that sync never examined it — which is the D3 rail that stops a gap being published permanently.
  • The merge compared against a timestamp the consumer had fabricated, so a stand-in always outranked the real row and an artifact could never heal a ghost.
  • enableSyncFromDriveState could not be switched on by anyone — no config key, no dev-tools toggle.
  • Only the newest candidate was ever tried, so the window where an L1 artifact is indexed before it is retrievable closed the feature for that drive.
  • A modal overflowed 204px at 320×568, carrying the Close button off a screen whose only job was explaining a refusal.

Measured, not modelled

Nobody had run an export at real scale. drive_state_scale_measurement_test.dart now does, at 41,767 files, and it replaced the proposal's figures — which had been weighed on a VACUUMed SQLite file, from when the plan was to publish the database itself.

was documented measured
serialised 34.63 MiB 52.16 MiB
gzipped 6.65 MiB 9.55 MiB
seal / import / render 4s / 9s / 4s

The size argument is therefore weaker than claimed, which only strengthens the document's own conclusion that size was never the reason to build this. The first run of that measurement reported 2.09 MiB at a 26× ratio, because its transaction ids interpolated a counter; real ids are 32 bytes of entropy and about a third of the payload.

It also showed the producer is the expensive half — peak near 950 MiB from a 263 MiB baseline — and that is the half running in a browser tab. And that an imported artifact was being re-downloaded and re-merged every sync forever, 8.5s to write zero rows.

Verification

1816 passing, 5 skipped; flutter analyze lib test clean. Every guard was mutation-tested — the mutation applied, the failing tests recorded, the mutation reverted. That practice earned its keep here: it caught two tests that passed against buggy code, a guard that could not distinguish having Turbo credits from having the Turbo transport, and three defects that only appeared when independently-green branches were combined.

Known gaps, stated plainly: nobody has run the app, no artifact exists on chain, and the import is untested above ~10 rows.

Downstream

docs/drive-state/DELIVERY_PLAN.md tracks ar-io-docs, ardrive-core-js and ardrive-cli. One item is independent of this feature and should ship on its own: the published ArFS spec calls the snapshot metadata field dataJson, while both implementations use jsonMetadata — anyone building from the docs today reads no metadata from any snapshot.

A published, encrypted, parsed-state blob a client imports in bulk rather
than replaying a drive's history entity by entity. Additive: snapshots
stay the ArFS interchange format and the fallback, and a client that does
not understand an artifact syncs exactly as it does today.

The case is measured rather than assumed. Consuming a snapshot costs one
AES decryption, one JSON parse and one insert *per entity*
(file_entity.dart:117) - ~42,000 of each on the drive we have been
testing, which is the ~80s of chunk processing in its sync log. An
artifact costs one decryption and a bulk insert. It is also smaller: a
42k-file database built and weighed is 31.31 MiB, 6.41 MiB gzipped,
against 43.92 MiB and ~11.37 MiB for the snapshot covering the same
drive. And producing it is cheap in the way snapshots are not - it is
already in the local database, so there is no chain re-read.

The security section leads because the obvious implementation does
permanent harm. The local database holds profiles.encryptedWallet with
its keySalt, and drives.encryptedKey with its IV; serialising the
database would publish a complete offline attack package on the user's
password, permanently, with no delete. Hence export from an allowlist
rather than dump, guarded by a test that fails when the schema grows a
new table or column. Also: authenticated encryption is mandatory and the
codebase's GCM boundary is 100 MiB, which a ~130k-file drive would cross
into unauthenticated CTR; and the artifact should be serialised rows
rather than a .db file, both to avoid handing an untrusted database to
SQLite's parser and to avoid welding the wire format to schemaVersion.

Covers how it composes with sync (one more obscuring range - HeightRange
needs no change), what ardrive-core-js and the CLI would need, and ArNS
as the discovery mechanism, which is already-built plumbing:
ArnsRepository points an undername at an arbitrary txId today.

No code. Open questions are listed rather than answered.

Reworked so it reads as a standard addition rather than an app feature.

- The export is now guarded by schema views rather than an allowlist plus a
  test. A view names its columns, so a later migration widening `drives`
  cannot reach the export; the exporter queries views only and is
  structurally unable to see `encryptedKey` or `keySalt`. Separating key
  material into its own store was considered and rejected as a dependency:
  it migrates wallet material out of a live database whose fixtures are
  stale at v19, and still leaves one drive exported from a database holding
  all of them. Worth doing on its own security merits, separately.
- States the governing principle up front: this is a cache and every
  failure is a fallback. Unknown version, failed decryption, failed
  integrity, unexpected row - all mean sync normally, never fail the drive.
  That is what makes it foolproof; the worst outcome is today's speed.
- The entity is specified in ArFS's own conventions, matching how
  entity-types.mdx documents Snapshot: a `Drive-State-Id` beside
  `Snapshot-Id`, the same `Block-Start`/`Block-End` meaning, and
  `Cipher`/`Cipher-IV` per privacy.mdx.
- Adds what ar-io-docs needs: a Drive State section in entity-types.mdx,
  plus data-model, reading-data and privacy updates.

It also records a bug found while checking the spec against reality. The
published Snapshot format says the metadata field is `dataJson`, in both
prose and example; the implementation reads and writes `jsonMetadata`, and
a real snapshot contains 189 `jsonMetadata` and zero `dataJson`. Anyone
implementing a reader from the docs would get no metadata from any
snapshot and silently fall back to fetching every transaction one at a
time - the exact failure this work exists to remove. Flagged for its own
fix rather than bundled here.

…posal PE-9205

Rewritten after working through discovery, encryption and metadata. The
substantive changes:

- Corrected sizes. The first model left `bundledIn` null when 188 of 189
  real nodes carry it, and assumed a uniform entity mix. Remodelled on the
  snapshot's actual composition the artifact is 34.63 MiB, 6.65 MiB
  gzipped, against 43.92 and 11.37 - 1.27x and 1.71x, not the 1.40x and
  1.77x first claimed. The size argument is correspondingly demoted: it is
  the weakest of the three reasons, not the headline.
- Privacy is a gain, not a cost, which the first draft had backwards. A
  snapshot of a private drive is not encrypted: Content-Type is
  application/json, there is no Cipher tag, and only the per-entity
  metadata values inside are ciphertext. Every file id, parent folder id
  and timestamp is public today. A fully encrypted artifact leaks none of
  it.
- The payload is signed by the drive owner. This is what lets discovery be
  cheap without being credulous: a name is a mutable pointer and proves
  nothing, so verification cannot live in the discovery path. It also
  fixes a practical gap - a bundled data item has no L1 header, so
  `GET /tx/<id>` 404s and its owner is otherwise knowable only through the
  GraphQL indexer.
- ArNS becomes the primary discovery path rather than an accelerator, with
  GraphQL as fallback. The indexer is the least reliable component in the
  stack - it is what rate limits and what truncated a drive list under an
  open circuit breaker - and an artifact should not need it to be found.
- Both transports are required, neither may become one. Turbo is a hosted
  service, and a protocol-level feature that can only be produced through
  it would depend on one operator staying available. A wallet-only user
  must be able to publish and read with no Turbo involvement. The
  signature is what makes L1 and bundled items verify identically.
- AES-GCM, never CTR: CTR's advantages are streaming and random access,
  neither of which applies to a buffered bulk import, and its lack of
  authentication is not theoretical when gateways have been observed
  serving truncated data.
- Completed the tag set against the ArFS standard - ArFS, Content-Type,
  Unix-Time and Data-Start/Data-End were all missing - and added
  Content-Encoding and Entity-Count, the latter as an integrity check
  rather than a statistic.
- Added extensibility (named sections; State-Version bumps only when an
  older reader would misinterpret, never for additions) and observability,
  whose rule is that "no artifact used" and "artifact rejected because X"
  must never look the same in the logs. That distinction is exactly what
  this month's diagnosis cost days for the want of.
- Stated why a new Entity-Type is required rather than a snapshot variant:
  reusing it would have old clients claim the artifact's block range from
  its tags, yield nothing from a body they cannot parse, and silently skip
  those entities while the watermark advances.

Every code and spec citation re-verified; corrected one line number.

The document implied it and never said it, which is a real gap when the
same file recommends *incremental* snapshots two sections later - a reader
could reasonably assume artifacts work the same way.

They deliberately do not, and the reasoning inverts. A snapshot is
expensive to produce because it re-reads the chain, so increments are what
keep production affordable. An artifact is a local database export, so
production was never the expensive part and the only cost is the upload.
That buys back the property worth more than size: it is self-contained.
Any single artifact suffices - no ancestor to locate, none that has to
still be retrievable, and no way for one missing link to invalidate a
chain, which is exactly the residual risk hanging over snapshot chains.

Recorded as policy rather than limitation: `Block-Start` is a tag, not a
constant, and the range composition already handles sources covering
different spans, so an incremental artifact is just one with a non-zero
start. Revisitable without a format break when a drive is large enough
that republishing whole state costs real money - which also makes the
open question on revision depth load-bearing, since that is the lever
keeping a full copy affordable as a drive grows.

Eight decisions closing docs/DRIVE_STATE_ARTIFACT.md section 10, so parallel
lanes share one answer instead of each inventing their own. Recorded as the
coordinator's calls for review rather than settled protocol - all are
reversible before anything is published to chain.

Two are deferrals rather than answers, and are marked as such: database
views for export safety (a schema migration on a database whose fixtures
are stale at v19 is the wrong thing to land unattended - a typed projection
plus a drift test is functionally equivalent today) and ArNS discovery
(needs an undername convention checked against the ARIO spec).

The export layer of the drive state artifact (docs/DRIVE_STATE_ARTIFACT.md):
a drive's current state as an object graph, the D1 section format, and the
exact inverse.

- read file_entries, folder_entries and the drive row for one drive only,
  current state and not revisions (decision D2)
- project every table column-wise so encryptedKey, driveKeyGenerated and
  keyEncryptionIv have no path out of the database, and profiles is never
  referenced (decision D7, proposal 2.1)
- assert the projection against the live Drift schema, so a migration that
  adds a column to an exported table fails the suite until someone says
  whether it may be published
- order rows by id, because the payload is signed and a signature over a
  non-deterministic encoding cannot be reproduced
- skip unknown sections and fields on read, and reject only a version an
  older reader would misread (proposal 6), with enumerated failure reasons
  so a rejection never looks like an absence (proposal 7)

The envelope and the entity only. No export, no upload, nothing published.

- `lib/drive_state/domain/drive_state_envelope.dart` seals a payload in the
  order the proposal fixes (3.3): sign the plaintext with the owner's wallet,
  gzip, then AES256-GCM under the drive key. Signing the plaintext rather
  than the encoding is what lets a bundled artifact, which has no L1 header
  and therefore no knowable owner outside a GraphQL indexer, verify
  identically to a top level one (2.2). Opening runs the exact inverse and
  checks the signature against the drive's known owner.
- Neither direction throws. Every way either can fail is an enumerated
  `DriveStateEnvelopeFailure`, so a caller logs a reason and syncs normally
  rather than failing a drive over a bad artifact (DECISIONS.md,
  non-negotiable 2). A bad signature and an artifact signed by somebody else
  are separate reasons, because they mean different things.
- D5 is enforced at the same boundary the uploader uses to choose GCM over
  CTR: a payload at or above `maxSizeSupportedByGCMEncryption` is refused
  with a reason, never encrypted with CTR and never split. Reading refuses a
  `Cipher` tag that is not AES256-GCM for the same reason.
- The signature has to travel with the payload it covers, so the compressed
  body is a small self-describing frame carrying the owner key, the signature
  and the payload. All big-endian, nothing 64 bit, because `ByteData` has no
  `getUint64` on the web.
- `lib/drive_state/domain/drive_state_entity.dart` carries the 3.2 tags,
  modelled on `SnapshotEntity` down to its conventions. `Block-Start` is 0:
  every artifact is a full copy that supersedes every earlier one (3.4). It
  is a distinct `Entity-Type`, not a snapshot variant, because reusing
  "snapshot" would have an older client claim this entity's block range from
  its tags and then sync nothing for it (3.1).
- The tag names the entity introduces are added to `EntityTag` and friends
  the way the existing ones are.

Tests are behavioural and were mutation checked: removing the size guard,
loosening it to strictly greater, ignoring the verification result, ignoring
the owner check, accepting any cipher, dropping the magic bytes check and
dropping the Block-Start tag each fail exactly the tests that name them.
Test wallets are generated in the test; no key material is committed.

Discovery and the observability vocabulary for the drive state artifact
(docs/DRIVE_STATE_ARTIFACT.md §4 and §7). No import, no sync integration.

- add a DriveStateEntityHistory GraphQL query, modelled on
  SnapshotEntityHistory: owners + Entity-Type "drive-state" + Drive-Id,
  sorted HEIGHT_DESC
- add DriveStateDiscovery, an interface an ArNS resolver drops into later
  (decision D6), and a GraphQL implementation returning candidates newest
  first by Block-End, re-checked client-side against the drive owner because
  the indexer is the least trustworthy component in the stack
- read a bundled data item and an L1 transaction alike (§4.4); nothing
  filters on bundledIn
- add the §7 outcome vocabulary - used, none-found, unknown-version,
  signature-failed, decrypt-failed, integrity-failed, count-mismatch,
  range-already-covered - and a [drive-state] reporter beside the existing
  [snapshot] instrumentation. The three kinds open with three phrases that
  are not substrings of one another, so "no artifact was used" and "artifact
  rejected because X" can never read the same
- a lookup that could not complete returns empty and is reported apart from
  "none found", so a drive is never logged as having no artifact when the
  gateway simply did not answer

Neither is key material, so neither was caught by the leak test - they are
withheld for correctness, and the export lane flagged the first itself.

`syncCursor` is an opaque cursor issued by one gateway's indexer and means
nothing to another, so an importer that adopted it would resume pagination
from an arbitrary position.

`lastBlockHeight` is worse, and was not flagged. It is the *producer's*
watermark, which is a different claim from the artifact's coverage. An
importer adopting one that sits above the artifact's Block-End would
believe it had synced a range the artifact never contained and skip it -
the drive watermark advancing past unsynced entities, which is exactly the
silent drop in SYNC_SKIPPED_ENTITY_PERSISTENCE.md, and the failure this
whole line of work started from. Coverage comes from the Block-End tag and
from nothing else.

Both are removed from `ExportedDrive` entirely rather than left nullable,
so no later code can put them back by accident, and a test asserts neither
name nor value reaches the encoded payload.

The discovery lane branched before the envelope lane's tags merged, so both
declared the same four tag names and the same Entity-Type value with
identical strings. The discovery lane flagged it as a merge-time edit and
described exactly what to do; this is that edit.

References now point at `EntityTag.driveStateId` / `stateVersion` /
`contentEncoding` / `entityCount` and `EntityTypeTag.driveState`, so there
is one definition of each tag name rather than two that agree today.

The reading half of the artifact: open the envelope, check what the tags
promised against what the payload holds, and merge one drive's rows into a
database that holds every drive.

Validation runs to completion before the first write, and the writes are one
transaction. A count mismatch, a Drive-Id that disagrees with the tag, or a
payload carrying another drive's rows leaves the database exactly as it was -
a partial import is worse than none, because it would leave rows nobody
trusted behind a watermark saying not to look again.

The merge reconciles rather than replaces. Rows are matched by primary key
and written only when the artifact's copy is at least as recent as the local
one by lastUpdated; a local row the artifact never heard of is kept, since it
is far likelier to be a recent upload than a deletion. The drive's key
material and sync cursor are never named by the update statement, so they
cannot be nulled out by an import.

The watermark comes from the Block-End tag and from nothing else. The export
withholds the producer's own lastBlockHeight for exactly this reason. The
same argument applies once more to Block-Start: an artifact whose coverage
starts above what this client has synced merges its rows but does not move
the watermark, because doing so would jump a gap nobody walked.

Every DriveStateEnvelopeFailure maps onto the coarser vocabulary the
discovery lane owns, as a switch expression so a new codec failure is a
compile error here rather than a silent default. Nothing throws: the outer
catch turns even an unforeseen failure into an outcome, and the caller falls
back to an ordinary sync.

The envelope signed its payload with `wallet.sign` and wrapped the result in
a hand-rolled binary frame (magic `ARDRVSTA`, frame version, signature type,
three uint32 lengths, owner then signature then payload). Both halves of that
were wrong.

ArConnect and Wander have deprecated arbitrary-data signing, so an extension
user could never have produced an artifact at all. Every ArDrive upload
already signs an ANS-104 data item instead, and that path those wallets still
grant. The artifact body is now a data item signed through that same seam —
`DataItem.sign` with an `ArweaveSigner`, the shape of
`ArweaveService.prepareBundledDataItem` and `BDISigner` — serialised with
`asBinary()` and encrypted.

Opening reverses it with the package's own reader rather than a parser of
ours: decrypt, `processDataItem` to parse and verify in one pass, confirm the
signer resolves to the drive's owner, then gunzip.

- the item's data is the gzipped payload, so the signature covers the bytes a
  reader holds before it decompresses anything, and unsigned bytes never reach
  the decompressor
- the item carries no tags, target or anchor; the ArFS tags that make an
  artifact discoverable stay on the enclosing transaction
- sign still precedes encrypt, AES-GCM is still the only cipher, and the
  100 MiB refusal still has no CTR fallback
- `signatureInvalid` and `ownerMismatch` stay distinguishable, which is what
  lets the fallback log say why a drive skipped its artifact
- `unsupportedFrameVersion` is gone with the frame it described; ANS-104 has
  no version field, so nothing could ever have produced it

Tests port to the new shape and keep their coverage — byte-identical round
trip, tampered ciphertext, another wallet's artifact, over-size, non-GCM
cipher — and gain a case that breaks the signature while leaving the signed
bytes alone. Neutering the verifier fails that case and the tampered-payload
case, which is the check that they are testing verification and not parsing.

The import lane mapped every `DriveStateEnvelopeFailure` onto an outcome,
including `unsupportedFrameVersion`. The signing rewrite deleted that value
along with the hand-rolled frame it described — ANS-104 has no frame
version field, so nothing could produce it any more.

Both branches were green on their own; only the combination was wrong,
which is the case a branch's own gate cannot cover.

Extends the plan past ardrive-web to ar-io-docs, ardrive-core-js and
ardrive-cli, with status per item and a sequencing that puts the parts
needing a human decision on their own line.

Two things checked in the sibling repos change what the proposal assumed:

ardrive-core-js has no snapshot support at all - its entityTypeValues is
drive/file/folder/drive-signature and parseSnapshotData does not exist
anywhere in the source. Adding drive-state there would be the first rollup
artifact core-js can read, which is more work than the proposal's section 8
implied and also the higher-value half, since core-js is what non-web
clients build drive state through.

The CLI creates snapshots through its own utility, and a comment there
attributes the body shape to a core-js function that does not exist. So the
CLI can already produce a rollup nothing in core-js can consume. The
drive-state reader belongs in core-js so that split is not repeated.

The acceptance test for the whole feature is named explicitly: an artifact
written by one implementation, read by another, yielding identical
entities. Until that passes, "cross-client format" is an assertion.

The previous revision claimed ardrive-core-js had no snapshot support and
that a CLI comment referencing `parseSnapshotData` was stale. Both wrong.
The local core-js checkout was sitting on an old feature branch rather
than origin/master, which has a complete 16-file `src/snapshots/` module,
a real `parseSnapshotData` used by `arfsdao_anonymous`, and concepts
deliberately mirroring this app's `lib/utils/snapshots/`.

The error is recorded in the document rather than edited out. It is the
stale-checkout failure the agentic framework warns about, made by the
coordinator on a sibling repo, and it made the downstream work look larger
and lonelier than it is.

Corrected consequences, all favourable: the range-composition machinery
already exists in core-js, so drive-state mirrors a proven structure; the
`parseSnapshotData` → `arfsdao_anonymous` read path is the seam to slot
beside; and section 3 is now scoped as `src/drive_state/` alongside
`src/snapshots/` rather than as a first-of-its-kind reader.

One real constraint surfaced in its place: `src/snapshots/index.ts` says
the module is not yet wired into the live listing path. Drive-state should
not overtake that integration, or it lands as a reader nothing calls -
flagged to coordinate with the desktop work rather than assumed.

D2 said the payload should carry current state only, not revision history,
on the reasoning that entries "cover everything the explorer renders". That
was false and I did not check it before binding it as a decision three
lanes built on.

`filesInFolderWithLicenseAndRevisionTransactions` - the query the file
explorer actually uses - INNER JOINs `network_transactions` twice, each
through a subquery over `file_revisions`. A file row with no revision
produces NULL on the ON condition and is dropped from the result. So an
artifact carrying entries alone would import 41,000 files and display zero
of them, in every folder, while global search and the folder-tree paths
(which do not join revisions) would still show them - an internally
inconsistent drive.

It would not heal either: the import advances the watermark to Block-End,
so the next sync queries only beyond it and never fetches the revisions
that would satisfy the join.

The import lane's own tests could not catch this. Every assertion about
landed rows reads `db.select(db.fileEntries)` directly, which is the one
read path that does not join revisions.

The payload must therefore carry file_revisions, folder_revisions and the
network_transactions rows they reference. This costs nothing against the
published size figures: the 34.63 MiB measurement already modelled entries
plus revisions plus network transactions. It was D2 that departed from
what had been measured.

Found by the independent import audit; verified against the query.

Composes the three merged drive-state lanes - discovery, the envelope, the
importer - into the source `docs/DRIVE_STATE_ARTIFACT.md` §5 puts above
snapshots and GraphQL, and wires it into `_syncDrive` ahead of the snapshot
pass.

- `DriveStateSyncSource` discovers, fetches through the existing
  `ArweaveService`/`DataGatewayFallback` seam, imports, and reports exactly
  one §7 outcome per drive per sync. It is the only layer that logs one:
  every layer below it returns its verdict because none of them knows the
  sync reached its end.
- The imported range becomes an obscuring range through the mechanism that
  already composes snapshots - it raises the `lastBlockHeight` seed
  `SnapshotItem.instantiateAll` turns into its `obscuredBy` accumulator, and
  the start of the total range `HeightRange.difference` subtracts from. No
  second mechanism, and nothing else in `_syncDrive` moves.
- Gated behind `enableSyncFromDriveState`, which defaults to false, and
  behind a drive key, because v1 is private-drive only (§2.6). With the flag
  off no discovery query is issued and nothing is constructed.
- Every failure is a fallback: discovery, fetch, import and any unexpected
  throw all leave the sync starting exactly where it would have. The
  artifact's coverage is clamped to the current block height so a lying
  `Block-End` cannot build a backwards `Range` and fail the drive.
- A transport failure - an unanswered discovery query, an unfetchable body -
  is logged as a warning note rather than an outcome: §7's vocabulary
  describes what happened to an artifact, and neither of those learned
  anything about one.

…ed entities PE-9205

Adds the creation half of the drive state artifact: export -> seal -> ArFS
entity, stopping short of upload.

- drive_state_creation_service.dart builds a prepared, unsent DriveStateEntity
  with Entity-Count from the export, Block-End from the drive's own watermark,
  Block-Start 0, and Data-Start/Data-End derived from the rows it carries. It
  has no upload collaborator to call.
- The D3 precondition runs first, before anything is read or sealed: a drive
  whose last sync skipped entities is refused, and so is one whose skip state
  cannot be established. Publishing a gap into an immutable artifact is the
  failure SYNC_SKIPPED_ENTITY_PERSISTENCE.md describes.
- drive_state_sync_skip_status.dart turns SyncCubit's skip report into a
  three-valued answer, so "cannot tell" is refusable rather than rounded down
  to clean. SyncCubit gains two read-only getters - when a sync last completed
  and which drives it covered - because an empty skip map and a clean one are
  otherwise the same value, and a scoped sync replaces the map wholesale.
- A cubit and confirmation modal show what would be published (drive, entity
  count, size, block range) behind an explicit Publish button. The upload seam
  is wired and its shipped implementation publishes nothing (D8).
- User-facing strings are hardcoded English, matching the statusMessage
  strings this surface already carries.

`folder_entries` and `file_entries` do not hold only what the chain said.
Sync writes a stand-in row for a ghost folder - named after its own uuid,
parented to the drive root - and DriveDao writes a placeholder for a
discovered drive's root folder so the drive can be opened before its
metadata arrives. Both are stamped with *now*; a synced row carries its
revision's chain commit time. The importer keeps a local row only when it
is strictly newer than the artifact's, so a fabricated row always wins:
publishing a drive that held one would replace a correctly synced folder
with a uuid-named ghost in every client that imported it, permanently,
because an artifact cannot be recalled.

Export only chain-derived rows. The discriminator is revision existence -
a revision is written only when real metadata is read - which is the same
signal DriveDetailCubit uses to tell a genuinely empty drive from one that
has never synced. `isGhost` alone would not do: the root folder
placeholder deliberately carries no marker, since the upsert that lands
real metadata leaves absent columns alone and the flag would stick
forever. Entity-Count follows the exported rows, so it stays honest.

Three guard weaknesses went with it:

* The drift guard had a fourth-table blind spot. The exported and withheld
  column lists were separate `if (table is X)` chains and the test named
  the same three tables literally, so a section added for a fourth table
  passed a guard that never looked at it. That matters because the obvious
  candidates - network_transactions, arns_records, ant_records - have no
  driveId at all, and exporting one would publish rows about the user's
  other drives inside a blob encrypted with one drive's key. Both
  classifications are now decided together in one place, driven by a single
  list of exported tables that the test iterates, and the test asserts every
  other table in the schema is refused.

* Nothing asserted that `profiles` is refused - it threw only by falling
  off the end of a dispatcher. Refusal is now the dispatcher's first check,
  with explicit tests for `profiles` and the revision tables.

* The leak test asserted one 4-byte base64 string, and never value-checked
  keyEncryptionIv. Drift's default serializer passes a Uint8List through
  untransformed, so a leak through a generated toJson() would render as a
  JSON int array and slip past a base64 assertion. The queries are now built
  by named functions so the test can assert the generated SQL names no
  withheld column and selects no star - the mechanism rather than one
  rendering - and the value assertions use high-entropy bytes checked in
  both forms.

…ressor PE-9205

Four security fixes to the drive state artifact, on a format that becomes
immutable once anything is published.

- The coverage claim moves inside the signed payload. `Block-End` lived only
  as a transaction tag, and the importer wrote it straight to
  `drives.lastBlockHeight` - so a third party could copy an owner's genuine
  artifact bytes verbatim, re-publish them under `Block-End: 9999999`, and
  pass every check: the signature verifies (they are the owner's bytes), the
  drive decrypts, `Drive-Id` and `Entity-Count` match. The watermark would
  jump to a height nothing was ever synced to and that range would never be
  queried again - the silent drop in SYNC_SKIPPED_ENTITY_PERSISTENCE.md.
  `DriveStateExport` now carries a required `coverage` claim, the importer
  refuses an artifact whose `Block-Start`/`Block-End` tags disagree with it
  (`coverage-mismatch`), and the watermark is set from the signed value. The
  tags stay: discovery needs them to order candidates without downloading.
- Decompression is bounded at `maxSizeSupportedByGCMEncryption`, the same
  100 MiB the seal side refuses to cross. gzip reaches ~1032:1, so a ~6 MiB
  artifact expanded to gigabytes, and verification could not help - the bytes
  are genuinely signed, so the bomb reached the decompressor by design. The
  bound is enforced during inflation, because a gzip trailer's recorded size
  is chosen by whoever wrote the stream. Returns `decompressedTooLarge`.
- `unsupportedSignatureType` maps to `signatureFailed`, not `unknownVersion`.
  It is an authorship failure, not "your client is old".
- The `Content-Encoding: gzip` tag is gone. The transaction's data is GCM
  ciphertext and gzip is two layers inside it; an AR.IO gateway echoes the
  tag onto the HTTP response (`ar-io-node`, src/routes/data/handlers.ts), so
  a browser would gunzip ciphertext and fail permanently. No other ArDrive
  entity sets it.

Every guard is mutation-checked: removing the cross-check, making `coverage`
optional, dropping the bound, reverting the signature mapping and re-adding
the tag each fail a test.

The export now carries only rows a revision backs. Two fixtures written
before that landed built folders through `addTestFilesToDb`, which writes
file revisions but no folder ones, so their folders read as local stand-ins
and dropped out of the export.

Claude-Session: https://claude.ai/code/session_01LFV6xYmFz2meXf5EW2M1FB
Conflict resolution and two integration fixes the merge exposed:

- exportDriveState reads the coverage claim through its own named query
  rather than folding lastBlockHeight into the drive-row projection, whose
  generated SQL is what the leak test asserts. All four reads now run in one
  transaction, so the claim and the rows it describes are the same snapshot.
- DriveStateEntity.fromEnvelope takes the coverage object instead of a
  blockEnd integer. The creation service was reading the watermark before
  the export and tagging that value, so a sync batch landing in between
  would have tagged a Block-End the signed payload contradicts - an artifact
  that rejects itself, paid for and permanent.
- The sync fixture now moves the producer's watermark before exporting, so
  its artifacts are self-consistent the way a real one is. The clamp test
  covers a genuine over-large claim; a new test covers a real body re-tagged
  with someone else's range.

vilenarios and others added 5 commits August 19, 2026 12:36
Six review findings against the creation, envelope and pricing paths. Each
one is a place where the code documented a promise it did not actually keep.

- the creation cubit emits after every await, and the modal that owns it is
  dismissible. Closing it mid-seal or mid-upload made `emit` throw, and in
  `prepare` that throw landed in the method's own catch, which emitted again
  and threw again with nothing left to catch it. Guarded at every resumption
  point with `isClosed`, the shape `DriveDetailCubit`, `DriveAttachCubit` and
  `refreshTurboBalance` in this same file already use. A publish that lands
  after its modal is gone is not cancelled — it is paid for — it reports into
  the log instead.
- the decompression bound was sound for the pinned `archive` 3.4.10, but only
  because the three write methods it overrode happened to be the ones
  `GZipDecoder` calls and the other three delegate to `writeByte`. Neither is
  contractual. Added a second gate on `length`, which every write path must go
  through whatever method admitted it, and a test that fails if a future
  `archive` writes bytes through anything the first gate does not see.
- `DriveStatePublishCostEstimator` documents that only an AR failure is fatal,
  then called `getFreeAllowance` unguarded — one collaborator's "never throws"
  away from a Turbo outage removing the feature from users paying in AR. Also
  swapped the balance guard from `.catchError` to `try`/`catch`, which is not
  the same thing: `.catchError` cannot catch a collaborator that throws on the
  way to returning its future.
- `DriveStateEnvelopeCodec.open` documents that it never throws, and caught
  the data item's stream `on Error` — which lets an `Exception` past the
  caller's fallback and turns a bad artifact into a failed sync, the one thing
  §2.5 forbids. Widened it, guarded the signature-type read, and wrapped the
  whole path once more so a step that grows a new failure mode later still
  cannot cost a drive.
- §2.3 sized the AES-GCM refusal at "near 120k entities", extrapolated from a
  VACUUMed SQLite figure. `seal` weighs serialised JSON, with a revision row
  per revision: 41,767 files x (695 + 1.05 x 701) = 57.0 MiB, so the crossover
  is ~73,000 files and the headroom ~1.75x, not ~3x. Corrected, with what eats
  the rest, and the test now holds the measured figures.
- `DriveStateEntity.addEntityTagsToTransaction` guarded its required tags with
  `assert`, which release builds strip. A null `Block-End` would have published
  `Block-End: null` — paid for, permanent, and refused by every reader
  including the client that wrote it. Now a real check that names every missing
  tag.
Closure is not acyclicity. Every parentFolderId now resolves, but A -> B -> A
resolves too, and getFolderTree recurses on parentFolderId with no depth
bound — so a loop hangs drive size, folder download, manifests and
share-folder selection. Permanently: once blockEnd == localWatermark the
same payload re-applies on every sync.

Local parents are read as well as carried ones, because a cycle need not
live wholly inside the payload. Re-parenting one carried folder onto a local
folder whose own ancestor is that carried folder closes a loop out of two
individually innocent rows, and a payload-only check passes it.

Chain data cannot produce a cycle; this guards a malformed or broken
producer, which is the case the threat model keeps.

estimate() returns a Future. The test body does not await the matcher, so the test can complete before the assertion resolves. Use await expectLater so a non-throwing estimate fails this test rather than leaking into a later one.

Comment thread test/drive_state/qa_findings_test.dart Outdated
vilenarios and others added 3 commits August 19, 2026 13:24
Nobody had ever run an export at the size of a real drive. The proposal's
size table came from weighing a VACUUMed SQLite file, back when the plan was
to publish the database itself; the shipped format is a serialisation of
rows, and JSON is bulkier than SQLite's binary pages.

Measured through the real exportDriveState over 41,767 files:

  serialised   52.16 MiB   (was documented as 34.63)
  gzipped       9.55 MiB   (was documented as 6.65)
  vs snapshot   1.19x smaller gzipped, 1.19x larger before

So the size argument is weaker than claimed, which only strengthens the
document's own conclusion that size was never the reason to build this.

The first run of the measurement reported 2.09 MiB at a 26x ratio, because
its transaction ids interpolated a counter. Real ids are 32 bytes of entropy
and about a third of the payload, so that was wrong by more than four times.
The fixture now draws ids and uuids at their true entropy, and the note is
in the doc for whoever re-derives this.

The GCM crossover is quoted as a range, 70,000-80,000 files: the per-row
extrapolation and the end-to-end weigh-in disagree by 10%, and they disagree
because row width is dominated by names and paths. The range is the honest
answer; a single figure would not be.

The measurement is committed and skipped by default behind a new measurement
tag, so the numbers in docs/ are reproducible without costing CI a minute.

The format version was a bare integer in two places - the `State-Version`
tag and the payload's `version` field - and one number cannot say both
"this is an addition you can ignore" and "this is a change you would
misread". §6.1 is a case study in what happens when it tries: an early
three-section payload verified, counted correctly, claimed honest
coverage, and restored a drive with an empty file list.

- add `DriveStateFormatVersion`, a `major.minor` value type with parsing,
  ordering and a `toString` that round-trips. One `current` constant, so
  the tag and the payload field cannot drift apart at the producer;
  `DriveStateEntity.currentStateVersion` and `driveStateFormatVersion`
  are gone.
- no patch component: there is no bug-fix level of "what fields exist",
  and two components match `ArFS: "0.15"`.
- reader rule: accept your own major at any minor, refuse a higher major
  and a lower major separately, each with its own message. The lower arm
  is explicit rather than left to the section checks, which would either
  misdiagnose it as a truncated payload or accept it outright.
- a version that will not parse - absent, `"1"`, `"1.0.0"`, `"x.y"`,
  more digits than an int holds identically on the VM and in a browser -
  is malformed, not unknown-version. A bare `"1"` is refused rather than
  read as `1.0`: no writer emits that shape and nothing is on chain, so
  tolerating it would be an untested path with no producer behind it.
- cross-check the unsigned tag against the signed payload field and
  refuse any disagreement, following the `Block-Start`/`Block-End`
  precedent. Reported as integrity-failed: it says the artifact's tag
  and body disagree, not that this client is old.
- `unknown-version` now covers a wrong major in either direction; the
  code is unchanged and the direction is in the detail.
…E-9205

The spec described the payload as "a container of named sections" without
ever saying what they are called, so another client could not implement a
reader from it — which is the document's whole purpose for core-js and the
CLI. §3.3 now lists all seven, says all seven are required and may be empty,
and says which two tables are deliberately absent and why.

D9 records the move to two-component major.minor, including the reason the
older-major arm is explicit rather than cosmetic: under mutation, a
structurally-current payload relabelled 0.9 was silently imported.

D10 records that arns_records and ant_records do not travel. Verified rather
than assumed: assignedNames is a JsonKey field on FileEntity, written into
and read back from the file's ArFS metadata on chain, so the drive-side fact
is authoritative content whichever client assigned the name — and it is what
the file list and details panel actually render. What is lost on a restored
drive is search-by-name until the ArNS repository refreshes. Reversible as a
minor bump under D9, which is the case semver was introduced to make cheap.

Also corrects the qa_findings header, which still claimed every test in the
file was expected to fail. They all pass now.

On the configVersion suggestion — declining deliberately, and recording why.

Both flags ship false, which is already the AppConfig constructor default. A stored config missing the key therefore already yields exactly the value the asset file would deliver, so a bump delivers nothing. What it would do is replace every user's stored config wholesale — including any dev-tools toggle they had set, and enableSyncFromDriveState in particular.

The advice becomes correct the moment either flag ships true in the asset file, and that is recorded next to the flags so whoever flips one sees it.

Two other notes from this review round: the 45 character path hyphenation nit points at a passage that was replaced in 2cde10e2e with measured figures, so it no longer applies. The stale qa_findings_test.dart header was real and is fixed in 1510ff435 — those tests all pass now, and the header still said every one was expected to fail.

…rows PE-9205

The round trip test proved a drive *renders* after an import. It said
nothing about what the rows contained, and the columns a user would most
notice losing — thumbnails, pins, licences, ArNS names, the hidden flag —
were guaranteed only structurally: named in the export's projection, named
in the import's companions, and asserted nowhere.

Adds thirteen tests to `drive_state_round_trip_test.dart`:

* one file carrying a deliberately non-default value in every optional
  column, asserted on the consumer's `file_entries` row, its
  `file_revisions` row, and through `watchFolderContents` where the value
  is user visible;
* `thumbnail` parsed back into `Thumbnail` via
  `DriveDataTableItemMapper`, not compared as a string, so a blob that
  survives but no longer decodes fails;
* `assignedNames` round-tripped through `parseAssignedNamesFromString`,
  which returns null for anything it cannot read;
* `customJsonMetadata` and `customGQLTags` asserted byte for byte and as
  decoded JSON, because these blobs are re-emitted as ArFS metadata;
* the licence pointer on the file row and the `licenses` row asserted
  together, plus that two licensed files keep two distinct licences;
* `isHidden` on a file and a folder, both ways, through `hasHiddenItems`
  and through the predicate the explorer filters with;
* a revision the consumer already synced, to prove the artifact's copy
  collides with it rather than forking — the assertion the date columns
  exist for, since `file_revisions` is keyed by `dateCreated`;
* a file whose optional columns are all null, so the null path is
  exercised beside the populated one;
* drives with folders and no files, and with nothing but a root folder.

Dates are compared against the producer's stored row rather than the
fixture literal: drift stores DATETIME as unix seconds, so sub-second
input is truncated before the export runs. A tripwire records that, since
the format carries milliseconds and would become the narrower of the two
if drift's storage ever changed.

No production defect found — every value survives unchanged. Each new
assertion was mutation-tested against a deliberate break in
`drive_state_export.dart` or `drive_state_import.dart` and confirmed to
fail.
…e list PE-9205

The scale measurement stopped at gzip, so the half of the pipeline most
likely to break was the half nothing exercised above ten rows: `seal`
permits a 52 MiB payload because it weighs the uncompressed size against a
100 MiB bound, and the import lands the whole drive in one drift batch.

- make the fixture describe a drive that could actually be published and
  imported: a root `folder_entries` row with the `folder_revisions` row that
  vouches for it, and a non-zero `lastBlockHeight`. Without the first, the
  importer refuses the payload outright because the drive's `rootFolderId`
  resolves nowhere; without the second, `DriveStateCreationService` would
  never have sealed it. Costs 509 bytes, and leaves every figure in
  `docs/DRIVE_STATE_ARTIFACT.md` §1.1 and §2.3 where it was
- seed from a generator created per call, and draw the root folder's ids
  last, so both tests build byte-identical fixtures and the ids §1.1 was
  measured over do not move
- add a second measurement behind the same tag: export, seal with a real
  wallet and real AES-GCM, import into a second empty database, then read
  the drive back through `DriveDao.watchFolderContents` and count what
  renders in every folder
- measure the same artifact imported twice, which is what the next sync
  does while the drive's watermark sits at the artifact's `Block-End`
- report process RSS at each stage boundary, with what it measures and what
  it does not stated in full: it is a VM figure and the conclusion that
  matters is about a browser tab

Two ways the drive state publish path could tell a user something untrue.

The publish precondition (DECISIONS.md D3) refuses to build an artifact from
a sync that skipped entities, because sync advances lastBlockHeight regardless
of skips and an artifact records that gap permanently and immutably. The
decision is implemented three-valued and refuses on "I do not know". Its
inputs were not that careful.

syncAllDrives probes for drive activity and sets aside every drive it believes
unchanged. Those drives are not synced, and they are not added to
failedDriveIds either, so a completed sweep left them satisfying every check
the precondition makes: a completion stamped, a coverage claim that did not
exclude them, and a skip map with nothing to say about them. They read as
clean off the back of a sync that never opened them.

What the probe establishes is that a hundred-transaction page of the owner's
Drive-Id-tagged transactions since the drive's watermark did not mention it.
That is a claim about the chain, not about what any sync read. So the report
now names the drives it examined, announced before the first drive is touched,
and SyncCubit keeps its skip record per drive instead of replacing it per
sync:

  - a drive the probe set aside keeps whatever the last sync that did open it
    established, which is nothing at all unless one did. This is the honest
    answer rather than "unknown": nothing synced the drive, so neither its
    rows nor its watermark moved - every writer of lastBlockHeight is reached
    only from inside a drive's own sync - and the last report about it is
    still true of it. It also fixes the case the old comment described as
    load-bearing, where syncing drive B erased drive A's record;
  - a sync that stopped early, by error or by cancellation, erases what it
    knew about the drives it had opened. It may have advanced a watermark past
    entities it never read and then died without reporting;
  - a drive that was examined and failed loses its entry for the same reason.

Second, ArweaveDriveStateUploader reported every L1 failure as one that spent
nothing. TransactionUploader.upload (arweave-dart v4.0.2, the pinned ref)
awaits _postTransactionHeader() before yielding its first event and only then
streams the chunks, so a failure part-way leaves a transaction that exists,
will be charged for, and is missing its data. An artifact is tens of MiB and
therefore always many chunks, so that window is always open. Telling the user
nothing was spent invites the retry that prepares a second transaction and
pays for it too.

uploadTx now reports the header post, and a failure after it returns a third
outcome carrying the transaction id and saying plainly that publishing again
costs again. Turbo is unchanged: a data item is one request, so a failure
there is a failure.

Nothing here publishes anything. Every upload in every test is a mock.
…9205

Measured at 41,767 files: re-importing the same artifact costs a 9.55 MiB
download, ~173,000 statements and about 8.5 seconds, and writes zero rows.
That was not a one-off. A successful import leaves Block-End and the drive's
watermark equal, and the no-rollback guard refuses only Block-End < watermark,
so nothing stopped the next sync repeating all of it on the autoSync
interval, indefinitely.

The guard stays `<`. An artifact whose range the drive already covers can
still carry entities a *consumer's* sync skipped, and importing it is how
those get repaired — widening to `<=` would lose that. What must not repeat
is re-importing the same artifact, so the identity checked is the transaction
id, and a different artifact at the same Block-End is still read.

Per session rather than persisted: holding one transaction id per drive means
a schema migration, and the cost avoided is per-sync, not per-launch.

Also corrects §2.3, which claimed the 100 MiB bound was "on what AES-GCM must
hold in one piece". Measured end to end, AES-GCM holds 9.55 MiB — exactly
what the network carries — while the bound is checked against the 52.16 MiB
serialised payload, so it guards neither the cipher nor the transport. What
it actually guards is the producer's memory, which peaks near 950 MiB from a
263 MiB baseline, and that is the half running in the user's browser tab.

Every widget test this modal had ran at the default 800x600 surface, which is
neither shape it ships in. The new tests pump it through showArDriveDialog —
the production entry path, so the dialog's own geometry is in play rather than
a bare Scaffold body — at 390x844, 320x568 and 1440x900.

The first thing they found is a defect. Only the confirm state passed
`scrollableContent: true`; the other five left their body unbounded. A long
refusal sentence at 320x568 overflowed by 204 pixels and carried its Close
button off the bottom of the screen, leaving the barrier as the only way out of
the modal whose whole job was to explain why publishing had been refused. None
of these states controls the height of what it renders — drive name, refusal
sentence, uploader error, transaction id all arrive from elsewhere at any
length — so all five now bound and scroll their own body.

- add a narrow-screen group to drive_state_creation_modal_test.dart covering
  the confirm, refusal, failure and published states, asserting no overflow,
  that the modal stays inside the viewport and within modalStandardMaxWidthSize,
  and that the confirm and close actions can be reached and hit
- the width assertion is not redundant with the overflow one: showAnimatedDialog
  passes insetPadding explicitly and Dialog reads a null insetPadding as zero,
  so the dialog reserves no horizontal margin and modalStandardMaxWidthSize is
  the only thing between this modal and the screen edge. A fixed `width:` is
  then clamped by BoxConstraints.enforce rather than overflowing, and is
  invisible to an overflow check
- add drive_state_web_platform_test.dart, which runs under --platform chrome as
  well as on the VM, and measures on the running platform where int.parse stops
  round-tripping: 16 digits compiled to JavaScript, 19 on the VM
- correct DriveStateFormatVersion's account of its nine-digit cap. It claimed a
  longer run of digits "parses to different values on the two platforms", which
  is not true from ten to fifteen — those are exact on both. The cap is sound
  but conservative, and the comment now says where the platforms actually part

If publishAndImport() rejects for an unrelated reason, this test passes without proving that the importer validates drives.rootFolderId. Assert the expected rejection outcome and root-folder-specific detail before accepting the refusal path.

Use a non-nullable return type for lastSyncCoveredDriveIds. The getter always returns a set, and the production adapter never passes null. Keep driveStateSyncSkipStatus nullable if direct callers need null to bypass coverage filtering; its null branch is not dead.

Preserve uncertain results in the creation state. DriveStateCreationCubit.publish maps every non-published result to DriveStateCreationFailure, which loses the structured txId and outcome. Retain these fields so future retry or presentation logic cannot treat a paid transaction as an ordinary failure.

… PE-9205

The artifact source is covered in isolation, with the snapshot source
deliberately switched off so nothing but the artifact can move the GraphQL
range. That left the configuration a drive with existing snapshots actually
runs - all three sources live - untested. sync_repository_composition_test
is that case: both sources on, asserting the exact block ranges each source
is left responsible for, because a gap between two of them is a permanent
silent drop while an overlap is only wasted time.

What it establishes:

- No gap. An artifact through B, a snapshot above it and GraphQL for the
  remainder together cover [0, tip], and the only block covered twice is B
  itself: Range is inclusive at both ends and the GraphQL range is built as
  Range(start: syncFromBlockHeight, ...), so the artifact's last block is
  re-walked. Idempotent - revisions upsert on their primary key - and in
  line with the look-back overlap the ordinary path already applies.
- A snapshot straddling B keeps the half above it. The obscuring
  accumulator is seeded with [0, B], so the snapshot is left [B+1, end];
  that band is neither re-walked over GraphQL nor dropped.
- A snapshot starting exactly at B does not serve B - GraphQL does.
- Two snapshots that overlap each other split the shared band rather than
  either dropping out or both serving it: the transaction they both hold is
  delivered to the parse stage exactly once.
- An artifact that fails to verify still leaves the snapshot source
  working, which is the fallback chain's core promise.

One fix, in the remaining case. A snapshot entirely below the artifact's
coverage is left with no sub-ranges and can serve no block, but was still
handed to SnapshotValidationService - a HEAD probe retried for up to ~50s
whose answer cannot change the sync either way. syncAllDrives makes these
routine rather than rare: its batched prefetch queries once per owner from
the lowest start height across their drives and gives every result to every
drive, so a drive an artifact moved far ahead is handed the snapshots its
neighbours needed. They are now dropped before validation, and named in a
log line so a shrinking snapshot count is never a mystery.

349-353: 🗄️ Data Integrity & Integration | 🔵 Trivial | ⚡ Quick win

Add an assertion for the drive watermark after a successful import.

The file proves which ranges each source is asked for. It does not prove what the sync leaves in drives.lastBlockHeight. Two writers touch that column in one sync: DriveStateImporter writes the signed Block-End, and _parseDriveTransactionsIntoDatabaseEntities later writes currentBlockHeight. Only an assertion shows which value survives, and a wrong value silently re-walks or silently skips blocks on the next sync.

Add a helper next to fileIds and assert it in the first group.

♻️ Proposed helper and assertion
   Future<Set<String>> fileIds() async => (await (db.select(db.fileEntries)
             ..where((f) => f.driveId.equals(driveId)))
           .get())
       .map((f) => f.id)
       .toSet();
+
+  /// What the next sync of this drive would resume from.
+  Future<int?> watermark() async =>
+      (await db.driveDao.driveById(driveId: driveId).getSingle()).lastBlockHeight;

Then, in group('an artifact and snapshots above it'):

test('leaves the watermark at the tip, not at the artifact\'s claim',
    () async {
  await sync();

  expect(await watermark(), currentBlockHeight,
      reason: 'the GraphQL pass walked through the tip, so a resume from '
          '$artifactBlockEnd would re-walk blocks already accounted for');
});

Keep the actions row outside the scroll view. scrollableContent exists, but body includes _buildActions(...); the actions row is therefore inside the SingleChildScrollView and its maxHeight constraint.

Add the Chrome test to CI

.github/workflows/test.yml runs scr test, which invokes flutter test without --platform chrome. Add a CI step for test/drive_state/domain/drive_state_web_platform_test.dart --platform chrome.

Three rules added to §5 that a reader has to get right and that each cost
time to learn here: a deep sync must not read an artifact; an artifact
already imported must not be imported again, keyed on transaction id rather
than range; and snapshots the artifact already covers must be skipped before
they are validated, not after.

None of those are obvious from the format, all three were found by running
it, and any other client implementing §5 would otherwise rediscover them the
same way.

D1's compression figure was the modelled 5.2x; measured end to end it is
5.46x. Delivery plan rows updated to what landed, plus two that were implicit
and are now explicit: localisation at ship time, and persisting the skip
ledger and the imported-artifact record across sessions.

The public path is the private one minus a layer: serialise, gzip, sign as
an ANS-104 data item, and stop. `Cipher` and `Cipher-IV` are absent, and
their absence is the discriminator. Format version stays 1.0 — nothing is
published to chain, so folding public support into the initial format means
there is never a world where some 1.0 readers handle public drives and
others do not.

Proposal §2.6 recommended private-only on two arguments, and neither holds.
"Public drives have least to gain" is false: the win is skipping ~420
GraphQL queries and ~42,000 metadata fetches, which a public drive pays
identically, and what it skips is the per-entity decryption — the cheapest
of the three per-entity costs. "A single blob enumerating every name, size
and relationship helps an adversary" is already conceded: a snapshot of a
public drive is exactly that blob, unencrypted, published today.

- `DriveStateProtection`, a sealed type with private constructors reachable
  only through a factory taking the drive's own `privacy` column with its
  key. Only the `public` arm yields the unencrypted variant, and the codec
  switches exhaustively over it — so publishing a private drive in the clear
  is not a check that could be skipped, it is a value that cannot be built.
- The cipher/privacy cross-check, both directions, reported as its own
  `privacy-mismatch` outcome: at the tags before the body is touched, again
  in the codec, and a third time against the signed payload's own `privacy`
  field, which the merge would otherwise write onto the local drive row.
- `DriveStateCreationRefusal.publicDriveUnsupported` and `isPrivateDrive`
  are gone. Ownership, write permissions, non-empty, the D3 skip
  precondition and the watermark all still apply to a public drive.
- The read path resolves the protection from the drive row rather than
  gating on `driveKey == null`, which could not tell a public drive from a
  private drive whose key had gone missing.
- D5's 100 MiB bound keeps its number and loses its justification: it was
  an AES-GCM constraint, GCM holds the compressed item (9.55 MiB against a
  52.16 MiB payload), and the public path has no cipher at all. It is now
  this format's own constant, founded on the producer's memory, with a test
  holding it inside `maxSizeSupportedByGCMEncryption`.
- The confirmation modal drops the encryption clause for a public drive and
  adds nothing in its place.
- §2.6 rewritten, §1.3, §2.2, §2.3, §2.4, §3.2, §3.3, §7 and §9 updated,
  and D11 recorded in DECISIONS.md.

Checked out PE-9205-drive-state-impl and ran its own scale measurement here,
so the comparison is two tests on one machine rather than my numbers against
its reported ones. Its sizes reproduce exactly, which is what makes the rest
of the table trustworthy.

The producer figure needed care. #2188 reports 'seal 4 s', which is its
jsonEncode plus gzip and matches at 3,893 ms. Its export step is a separate
9,111 ms the headline omits, so like-for-like is 13,004 ms against 679 ms.

Also adds gzip timing and process RSS to this branch's measurement, so both
tests now report the same spans.

Merges PE-9205-drive-state-impl and swaps only the payload. Its uploader,
discovery, sync composition, observability, UI and config flags are reused
unchanged — they deal in bytes and tags, so the container was never their
business, and rewriting them would have thrown away work two reviews had
already hardened.

The producer now builds a SQLite database with ATTACH + INSERT ... SELECT
instead of jsonEncode. Two lines in the creation service, plus a platform
sink: ATTACH needs a path, and native and web disagree about what a path is.

Web is not supported yet and says so rather than failing halfway. The web
database is drift's sql.js backend, whose SqlJsDatabase.export() returns
`main` — there is no way to read an attached database's bytes back out, and
drift surfaces no filesystem. The sqlite3 WASM path does have one, which is
what makes both directions work in #2196, and reaching it means moving off
drift/web.dart. Native and the CLI work today.

Known state: the read side still parses JSON, so this half does not yet
round-trip. Four of the creation-service tests fail with FormatException
because they utf8.decode the payload to assert its shape — they assert the
container, and are rewritten with the importer.

The reader now attaches the artifact, runs PRAGMA integrity_check, matches its
sqlite_master against the frozen schema byte for byte, and only then reads a
row. The rows travel through the same DriveStateExport the JSON reader
produced, so _merge is untouched: ghost folders, folder-cycle detection,
newer-row-wins and the shared network_transactions derivation are the
implementations two reviews already hardened.

That is deliberate. Reimplementing that merge in SQL to save a few hundred
milliseconds would trade a reviewed guard for a new one nobody has read.
Moving the bulk tables to INSERT ... SELECT is a behaviour-neutral
optimisation and belongs after this is green, not before.

One version constant for the branch, moved to 0.1, and taught that in the 0.x
range the MINOR is the compatibility unit. 0.1 and 0.9 share a major, so a
major-only check would let a later staging build read an artifact an earlier
one published meaning something different — which is the whole reason to be in
the 0.x range while experimenting.

Test fixtures now follow DriveStateFormatVersion.current instead of restating
'1.0'. Restating it is how a fixture ends up asserting a version the code no
longer speaks, which is exactly what happened: every import rejected on
version, and the tests that then read restored rows hung on Stream.first of an
empty result rather than failing on the real cause.

The round-trip fixture builds a real SQLite payload rather than a fixture's
idea of one. 26/26 pass: export, seal, tags, import, merge, and the file list
rendering from the restored drive.
