Fixes #24960

Clause-②: no (narrowing)

Narrowing face: a SqlDriver.connect() that resolved now refuses. On a SQLite file whose bytes are not a SQLite database, connect() used to log and swallow SQLITE_NOTADB and resolve; it now rejects with SqliteDatabaseFileError (code: 'SQLITE_NOTADB', filename, a message naming the file), in development and production alike. On a development boot, resolveSqliteDriver re-throws that refusal instead of stepping down to wasm SQLite, so the operator's file is no longer renamed to FILE.corrupt-TIMESTAMP and replaced with an empty database. Nothing exported changes shape.

Route A, the card's seat ruling, as dispatched: the producer refuses the file, and the step-down classifies the code. B (consumer-only sniffing) and C (keep the wasm quarantine as dev recovery) are not taken.

What changed

• packages/drivers/driver-sql/src/sql-driver.ts, the applyAutoVacuumIncremental region only. The first-statement codes that are a verdict on the file now sit in one table, SQLITE_FILE_REFUSALS: SQLITE_CANTOPEN (as runtime: a declared sqlite datasource whose file cannot be created never settles its connect, so the boot is refused only by a plugin start timeout (30 s, 120 s after PR #23694) that names neither the datasource, the path nor the open error #23696 shipped it, same words) and SQLITE_NOTADB (new, "is not a SQLite database, and was left as it is"). Either throws SqliteDatabaseFileError before anything is written. Every other PRAGMA failure keeps today's warning and return false.
• packages/drivers/driver-sql/src/sqlite-database-file.ts: the class doc names the new code. Doc only.
• packages/services/service-datasource/src/sqlite-driver-fallback.ts: isSqliteFileOpenFailure adds SQLITE_NOTADB, with its doc list and one sentence in the module note. This is the cross-lane line for domain:services that the dispatching seat declared. resolveSqliteAbsentFileTarget, knexConfigFor and the probe body are untouched, because driver-sql: the read-only probe's absent-file test (existsSync) reads an unopenable SQLite path as absent, so os migrate plan opens an empty in-memory database, reports the datasource connected, and plans DDL into a file that cannot exist #24961 is changing those in parallel. A local git merge-tree of this head with that branch's head 28d5dd67e is clean.
• .changeset/24960-sqlite-notadb-connect.md: patch for @objectstack/driver-sql and @objectstack/service-datasource. It carries the Clause-②: no (narrowing) line, the BREAKING banner with the operator's fix, and an ADR-0087 not-required (no-migration-prescription) disposition.
• Two new pin files: packages/drivers/driver-sql/src/sql-driver-24960-sqlite-not-a-database.test.ts and packages/services/service-datasource/src/__tests__/sqlite-driver-fallback-not-a-database.test.ts.

Premise, measured (better-sqlite3 13.0.3, Node v22.22.0)

• H1 holds. On a plain-text file, better-sqlite3's new Database(file) succeeds, and the first statement, PRAGMA auto_vacuum, throws code: 'SQLITE_NOTADB' ("file is not a database"). So do PRAGMA journal_mode and SELECT 1. A file whose 100-byte header was overwritten past the magic string answers the same code. On base, applyAutoVacuumIncremental matched only SQLITE_CANTOPEN, logged "Failed to set PRAGMA auto_vacuum=INCREMENTAL" and returned false, so connect() resolved.
• H2 holds. With the code in isSqliteFileOpenFailure, the development probe re-throws at the native rung, and wasm's quarantineCorruptFile is never reached for a declared datasource whose addon loads. The pins assert that the file's bytes are unchanged and that the directory holds only that file: no .corrupt-* sibling, no journal, no WAL.
• H3 holds. The card's "native better-sqlite3 unavailable (ABI mismatch or not built)" line is the step-down's own NATIVE_SQLITE_WASM_FALLBACK_WARNING ("dev using wasm SQLite"). The driver's similar warning fires only for a native load failure, which SQLITE_NOTADB is not. With this change the step-down never runs on this path, so the warning no longer prints: the pin asserts warn was never called, and the public-door run below prints neither line.
• Does any caller rely on connect() resolving over a file that is not a database? I found none. I grepped the tree for NOTADB / "not a database" / SQLITE_CORRUPT / "disk image is malformed", for tests that write arbitrary bytes into a .db file, and read every resolveSqliteDriver caller.
  • os db clean: it called resolveSqliteDriver({ dev: true }) and then VACUUMed. On base, a garbage file was moved aside, and the "clean" reported the empty replacement's size. Now it refuses the file, which is the better answer.
  • The development telemetry sibling (telemetry-datasource.ts): it already drops its separation on any throw, catch then undefined, the same as for fix(cli,service-datasource): under bin/run-dev.js (NODE_ENV=development) an unopenable SQLite datasource steps down to an in-memory engine, so a dev-mode os migrate audit-mail-bodies reports an unreachable archive as examined and clean #24950's codes. The boot continues.
  • dev-organization-ownership-upgrade.test.ts writes text into dev.db but drives a fake CLI, and no driver opens it.
  • TursoDriver local and replica modes open the file through this SqlDriver.connect(). Measured: a file written by @libsql/client with an encryptionKey answers better-sqlite3 with SQLITE_NOTADB. Such a datasource is now refused at connect, naming the file. Before, connect resolved and every read through Knex failed with the same code, so nothing that worked stops working.

Evidence

Pins (all at head 6d3dd6247, under os-verify-lock):

• driver-sql, sql-driver-24960-sqlite-not-a-database.test.ts: a plain-text file is refused with SqliteDatabaseFileError. The pin checks code = SQLITE_NOTADB, filename, a message naming the file and carrying the cause, the same bytes after, and the directory listing equal to the one file. It runs under both NODE_ENV=development and NODE_ENV=production. Controls: a real database reconnects and answers, and an empty file connects. Result: 8/8 with the runtime: a declared sqlite datasource whose file cannot be created never settles its connect, so the boot is refused only by a plugin start timeout (30 s, 120 s after PR #23694) that names neither the datasource, the path nor the open error #23696 file.

• service-datasource, sqlite-driver-fallback-not-a-database.test.ts:

  • development resolveSqliteDriver rejects with the driver's refusal, warns nothing, and leaves the file untouched;
  • production returns native unprobed, and its connect() refuses the file;
  • DatasourceConnectionService.connectDeclared reports availability: 'failed' with a reason naming the file and registers no driver, in development and production, and the file is untouched.

  Result: 24/24 with the fix(cli,service-datasource): under bin/run-dev.js (NODE_ENV=development) an unopenable SQLite datasource steps down to an in-memory engine, so a dev-mode os migrate audit-mail-bodies reports an unreachable archive as examined and clean #24950 file and sqlite-driver-fallback.test.ts.

• Whole packages at c5b499cf0, before merging main: driver-sql "Test Files 226 passed | 12 skipped (238) · Tests 3696 passed | 209 skipped (3905)" (the skips are the live PG/MySQL cells); service-datasource "Test Files 51 passed (51) · Tests 912 passed (912)". tsc --noEmit exit 0 for both. tsc --listFiles includes each new test file (1 hit each).

• The merge of origin/main at 4fe3af9d7 brought feat(spec,objectql): report a caller value a stored expression replaced, as DroppedFieldsEvent reason stored_expression #24778, feat(spec)!: addRecord says what renders — enabled required, position top, mode/formView retired #24970 and docs(deployment): branding env vars follow the runtime — OS_PRODUCT_NAME defaults to ObjectOS, six readers added, precedence per posture #24990. They touch spec, objectql, ui and docs, none of these packages, and the targeted pins above were re-run on the merge head.

Ablation (scripts/ablation-replace.mjs WRAP with a trap restore, at c5b499cf0):

• Leg A, the driver. The SQLITE_NOTADB table row was mutated to ABLATION_24960_NOTADB: anchor 1 to 0, blob b99ad91eeb7e to 3eb1e25b29ac. driver-sql was rebuilt, and ablation-dist-preflight.mjs found the marker in 2 built files.
  • Predicted and observed: driver-sql "2 failed | 6 passed". Red: the development and production refusal pins (connect() resolved for a file that is not a SQLite database). Green: the controls and the runtime: a declared sqlite datasource whose file cannot be created never settles its connect, so the boot is refused only by a plugin start timeout (30 s, 120 s after PR #23694) that names neither the datasource, the path nor the open error #23696 file.
  • Predicted and observed: service-datasource "4 failed | 9 passed". Red: development resolved to engine sqlite-wasm; the production refusal was undefined; both DatasourceConnectionService cases read 'available'.
  • Restore proved: blob == HEAD, git diff HEAD empty. After the rebuild, preflight --absent found the marker in none of the 6 built files, and the tree was clean.
• Leg B, the step-down. || code === 'SQLITE_NOTADB' was mutated to ABLATION_24960_SD: blob 165d52e2d851 to bda6c0c91769. The subject is a relative src import, so this leg needs no dist step.
  • Predicted and observed: "2 failed | 11 passed". Red: the two development cases. Green: the two production cases, which the driver alone carries, and the 9 cases of fix(cli,service-datasource): under bin/run-dev.js (NODE_ENV=development) an unopenable SQLite datasource steps down to an in-memory engine, so a dev-mode os migrate audit-mail-bodies reports an unreachable archive as examined and clean #24950.
  • Restore proved: blob == HEAD, git diff HEAD empty.

Public door, the card's own: bin/run-dev.js migrate apply --yes --database-url file:main.db over a dist/objectstack.json that declares archive (driver: sqlite, autoConnect: true) on a plain-text file, at head 6d3dd6247 after a turbo run build --filter=@objectstack/cli^... (60/60).

• Object bound to archive: the run prints datasource 'archive': connect failed — SQLite database file '…/data/archive.db' is not a SQLite database, and was left as it is: PRAGMA auto_vacuum - file is not a database. (1 object(s) bind to it explicitly … fail-fast per ADR-0062 D5) and exits 1. The md5 is unchanged and data/ holds archive.db main.db.
• autoConnect only: the run prints WARN datasource 'archive': connect failed — … is not a SQLite database … — degrading (datasource left unconnected), then Applied 0 change(s), and exits 0. The md5 is unchanged, there is no .corrupt-* sibling, and no step-down warning prints.
• The card measured the base on the same door: the file was renamed, an empty 16384-byte database was written, and the run read connected.

Driver ledger (pnpm check:driver-conformance):

• Before, at 4b8f597ba: "55 covered cell(s), 0 in the DEBT ledger, 0 exempt"; dialect axis 9 suites, 8 matrix and 1 named, 0 in the DIALECT ledger.
• After, at 6d3dd6247: the same counts. The ledger did not move.

Gates. node scripts/pm/dispatch-gates.mjs --commands --repo objectstack-ai/objectstack (no paths) at 6d3dd6247 derived 72 commands: the seat's 55 plus 17 for the changeset and the new test files. I ran each one once, sequentially, with its exit captured before any pipe, and all 72 exit 0. Two answered exit 3 (PREREQUISITE NOT MET) on the first pass and were re-run after their prerequisite:

• check-plugin-teardown-shape.mjs --self-test needed its pinned fixture commit, fetched at depth 1;
• check:dual-build-cjs-loads needed every package's dist/, from a turbo run build that was 75 of 76 cache hits.

--ran reconciliation: "72 derived, 72 run, 0 NOT-MEASURED, 0 UNRUN", a derived zero because all 72 recorded an exit code. CI owns the full farm and test:repo.

Acceptance notes

• SQLITE_CORRUPT, the same defect one code over, is not in this PR. It is reported to the seat; this PR leaves it alone. A SQLite database truncated inside its 100-byte header answers the first PRAGMA with SQLITE_CORRUPT ("database disk image is malformed"), which connect() still swallows. I ran the same door at this head with an object bound to archive: archive.db was moved to archive.db.corrupt-1792539192447, an empty database was written in its place, the run read datasource 'archive': connected under the "native better-sqlite3 unavailable" warning, and it exited 0. The fix would be one more row in SQLITE_FILE_REFUSALS and one more code in isSqliteFileOpenFailure. It stays out because the ruling and the claim name SQLITE_NOTADB, and sqlite-driver-fallback.ts is also held by the driver-sql: the read-only probe's absent-file test (existsSync) reads an unopenable SQLite path as absent, so os migrate plan opens an empty in-memory database, reports the datasource connected, and plans DDL into a file that cannot exist #24961 claim, so the in-place exemption does not hold.
• A residual rename this route cannot reach. When the native addon cannot LOAD (an ABI mismatch) and the declared file is not a database, the native rung cannot read the file to classify it. The step-down still goes to wasm, which renames the file. I measured this with the fix(cli,service-datasource): under bin/run-dev.js (NODE_ENV=development) an unopenable SQLite datasource steps down to an in-memory engine, so a dev-mode os migrate audit-mail-bodies reports an unreachable archive as examined and clean #24950 suite's own load-failure seam (acquireRawConnection answering a real ERR_DLOPEN_FAILED): the run resolved to sqlite-wasm, and data/ held archive.db and archive.db.corrupt-TIMESTAMP. It lives in the wasm quarantine, which the claim scopes out.
• The probe body's comments in sqlite-driver-fallback.ts ("refuses a file it cannot open or create") still name only the open-failure half. I left them unedited to stay off the driver-sql: the read-only probe's absent-file test (existsSync) reads an unopenable SQLite path as absent, so os migrate plan opens an empty in-memory database, reports the datasource connected, and plans DDL into a file that cannot exist #24961 region.
• After this branch's last merge, main gained fix(plugin-auth): the register form's Application Type reaches the OAuth provider as application_type #24992 (plugin-auth), which this diff does not touch. I did not merge it, so the gate union stays measured on the head it names.

What this run could not see

• 1 changed file(s) yielded no anchor (packages/drivers/driver-sql/src/sqlite-database-file.ts) — pages documenting those are invisible to this run
• the SDK route bridge reached 54 of 206 client-bound route-ledger rows — the other 152 have no registrar path: tail to select them, so pages documenting THEIR client methods cannot appear above, on this or any run. Of those 152: 0 are remediable by widening that discovery convention (an in-repo file declares the path; the convention did not scan it); 55 are structural — on a ledger where NOT ONE row is declared in-repo, so no discovery change reaches them at any price; 97 are undecided (no in-repo declaration, on a ledger that has other in-repo registrars — absence and an unreadable spelling are not distinguishable here). The rows themselves: node scripts/docs-audit/affected-docs.mjs --bridge-coverage
• a page that states a rule by its inputs shares no identifier with the emitter that implements the rule, so an emitter-only diff cannot list it — not on this run and not on any run. Measured on fix(driver-sql): emit varchar(maxLength) for a text field a declared index keys on #11430: content/docs/protocol/objectql/types.mdx documents the text-family column mapping by the ObjectQL type names it maps FROM (text / textarea / html) while the diff changed createColumn; it went unlisted, and it was the page that diff falsified, in four places. No shared token exists to detect this on, so a rule your change carries has to be re-read by hand in the pages that restate it.
• a key NAME is not a key, so the hand re-read the line above prescribes can land on the wrong schema. The same spelling is authorable on one governed type and a [REMOVED] tombstone on another for each of active, aria, joins, objects, template, tools and version (censused on [finding] tools is a key on BOTH AgentSchema (tombstoned, dead) and SkillSchema (live, cloud-attested), so a name-based search attributes skill examples to the agent key — it produced a false stop-the-line alarm on PR #19059 #19093 over the liveness ledger's governed types, top-level keys); nothing in a search result distinguishes the two, so a grep hit on a LIVE example reads as evidence about the DEAD key. Measured on fix(spec): the agent.tools liveness row says dead — it claimed live on a key the schema tombstoned #19059: content/docs/ai/agents.mdx was reported as contradicting the agent.tools tombstone over its tools: example at :161, which is inside the defineSkill({ block opened at :155 — the page was already correct. Settle ownership by PARSING the value against both schemas, never by the name: that literal PASSES SkillSchema, and as an AgentSchema it FAILS at tools with the tombstone prescription. ⛔ These names are not the whole class — a key retired through a .strict() guidance map leaves no tombstone in the walked shape and none of them here (tool.category, live as AIToolDefinition.category).

Coarse fallback — 13 page(s) merely mention a changed package (the pre-#9192 predicate, kept for the deliberately-wide backstop): node scripts/docs-audit/affected-docs.mjs --json 62bc1293080968f0ec8c3d31dc1f9ed8da4077df → packageMentionDocs.

Which tree this was computed on

This run read content/docs from befe1313369ede18acf6da6e40349e2cb62f6063 — the merge of head 69f54e9130bebfc69d274ae74b10fb27e50a250f into base 62bc1293080968f0ec8c3d31dc1f9ed8da4077df, which is what actions/checkout gives a pull_request run. Not the PR head.

A worktree cut from an older main holds a different content/docs, so re-deriving there can legitimately return a different list — that is a different tree, not a wrong row. To answer on the same tree:

# while this PR is open — GitHub drops the merge commit once it closes
git fetch origin befe1313369ede18acf6da6e40349e2cb62f6063 && git checkout befe1313369ede18acf6da6e40349e2cb62f6063
# afterwards, rebuild it from the two parents, which stay fetchable
git fetch origin 62bc1293080968f0ec8c3d31dc1f9ed8da4077df 69f54e9130bebfc69d274ae74b10fb27e50a250f && git checkout -B drift-repro 62bc1293080968f0ec8c3d31dc1f9ed8da4077df && git merge --no-ff 69f54e9130bebfc69d274ae74b10fb27e50a250f

node scripts/docs-audit/affected-docs.mjs --json 62bc1293080968f0ec8c3d31dc1f9ed8da4077df

⚠️ That checkout carried uncommitted changes, so the commit above does not fully identify what was read.

Advisory only, and a precision-first one (#9192): a page is listed because it names a
symbol, wire route or SDK method this diff touched — not because it mentions a changed
package. Each row says which anchor put it there, so a wrong row is reportable rather than
merely annoying. To re-verify, run the docs-accuracy-audit workflow scoped to these files:
node scripts/docs-audit/affected-docs.mjs 62bc1293080968f0ec8c3d31dc1f9ed8da4077df → pass the list as
args.docs, on the commit named under Which tree this was computed on.

Seat review · domain:engine seat 2 · session_01QK6pdbxKZiHdFApL8RYVh9 · 2026-10-21T00:53Z · head 6d3dd6247 · verdict: REWORK, patch round 1 (one item).

• Check Changeset is red, and it is right. The PR declares Clause-②: no (narrowing), and the gate reads narrowing as BREAKING, which ships minor during the launch window (job 118956257961). The changeset says the opposite: "It ships as patch … breaking-ness is carried by this banner … not by the level". Raise @objectstack/driver-sql and @objectstack/service-datasource to minor (both packages carry the narrowed behaviour), and correct that sentence. Nothing else changes.
• The rest of the review holds on this head: the diff stays inside the claimed regions (applyAutoVacuumIncremental / SQLITE_FILE_REFUSALS, isSqliteFileOpenFailure and its doc); 40 of 41 check-runs on 6d3dd6247 are success or skipped; the pins carry an ablation with predicted equal to observed.
• The dev's open question (SQLITE_CORRUPT), answered by the seat: B. It is filed as the family's closing card driver-sql: two more SQLite file failures read connected on a declared datasource — SQLITE_CORRUPT (a truncated header) is swallowed at connect, and a dangling-symlink directory passes makeDatabaseDirectory; on a development boot both step down to wasm #25019, together with driver-sql: the read-only probe's absent-file test (existsSync) reads an unopenable SQLite path as absent, so os migrate plan opens an empty in-memory database, reports the datasource connected, and plans DDL into a file that cannot exist #24961's dangling-symlink finding, serial after this PR and PR fix(driver-sql): a read-only boot refuses a SQLite datasource whose file can be neither opened nor created, instead of reporting it connected #25007. This PR keeps its claimed scope.
• The class b finding (Turso encryptionKey in local mode) is filed as turso: a local-mode datasource's declared encryptionKey is never applied, so the database file is written in plaintext that any SQLite reader opens without the key #25020 for triage.
• The contract review owed for the narrowing face runs on this head; a changeset-only push does not move it.

The PR is a draft on an internal branch (head repo = base repo), 324 changed lines, and its file list touches no governed surface.

① Derived judgments

Each accept-set or public-surface change the diff implies, named right or wrong:

1. SqlDriver.connect()'s accept set — narrowed by exactly one code, right. On base, applyAutoVacuumIncremental refused only SQLITE_CANTOPEN; every other first-PRAGMA failure logged and returned false, so connect() resolved. At the head the lookup is a two-row private table, SQLITE_FILE_REFUSALS (SQLITE_CANTOPEN with the runtime: a declared sqlite datasource whose file cannot be created never settles its connect, so the boot is refused only by a plugin start timeout (30 s, 120 s after PR #23694) that names neither the datasource, the path nor the open error #23696 words verbatim, SQLITE_NOTADB new), and a hit throws SqliteDatabaseFileError(filename, words, cause). Every other code keeps the base path unchanged: native-load failures still warn the step-down one-liner and return false; anything else keeps the full warning and false. The refusal is raised before anything is written: the PRAGMA auto_vacuum read is the connection's first statement and applySqliteJournalMode (the WAL switch) runs only on true, so no journal, WAL or .corrupt-* sibling can appear; the driver pin asserts the bytes and the directory listing. :memory: and the openedEmptyInMemory redirect never answer SQLITE_NOTADB. Exactly route A as ruled; B and C are not taken.

2. SqliteDatabaseFileError's code set — grows by one, right; it is not a public export. code is the cause's own: an operating-system code from ensureDatabaseExists (ENOENT, EACCES, ENOTDIR, EEXIST, …), SQLITE_CANTOPEN, and now SQLITE_NOTADB. Its shape (name, code, filename, cause, message SQLite database file 'PATH' WORDS: REASON) is unchanged. packages/drivers/driver-sql/src/index.ts does not export the class, so the consumer contract is duck-typed name + code (the service-datasource pin reads it exactly so). No api-surface artifact moves; the changeset's sentence about the class keeping its shape is accurate, and stronger than it needs to be.

3. resolveSqliteDriver's step-down — narrowed in development by the same one code, right. isSqliteFileOpenFailure is /^E[A-Z0-9]+$/ || SQLITE_CANTOPEN || SQLITE_NOTADB, judged on code alone, no message text. In development the native rung's connect() now throws before the probe's SELECT 1, the predicate matches, and the refusal is re-thrown: no wasm rung, no in-memory rung, no NATIVE_SQLITE_WASM_FALLBACK_WARNING (the pin asserts warn never called, which also retires the card's wrong-cause line). Production is untouched: native returned unprobed, refusal at the service's connect. The native-load step-down (ERR_DLOPEN_FAILED, the bindings no-code case) is unchanged, and the fix(cli,service-datasource): under bin/run-dev.js (NODE_ENV=development) an unopenable SQLite datasource steps down to an in-memory engine, so a dev-mode os migrate audit-mail-bodies reports an unreachable archive as examined and clean #24950 pins and the mocked sqlite-driver-fallback.test.ts cases carry no old-behaviour pin for a non-database file. The module note's claim "every rung opens the same file, so no rung can cure this" is true of the wasm rung in the cited code: WasmSqliteConnection.open reads the bytes, new SQL.Database(bytes) or PRAGMA quick_check throws, and quarantineCorruptFile renames to FILE.corrupt-TIMESTAMP and starts an empty database. Only this PR's classification keeps a declared datasource off that path; the quarantine itself is unchanged, by the claim's scope.

4. Callers whose answer flips — all flip to the ruled answer; one is unlisted by the dev.

   • DatasourceConnectionService.connectDeclared through the factory's sqlite arm: the throw reaches handleFailure; an object bound to the datasource (or a mapping, or boot-critical) is fail-fast per ADR-0062 D5 (exit 1, the message carries the file), autoConnect-only is warn … degrading (datasource left unconnected), state failed, no driver registered. Pre-existing mapping, now reached; pinned in both modes. Right.
   • os db clean (dev: true): before, a garbage primary was quarantined and the empty replacement VACUUMed and reported; now VACUUM failed for FILE: …, exit 1, file untouched. Right.
   • provisionTelemetryDatasource (the dev telemetry sibling): any throw is caught to undefined, so a garbage telemetry file now leaves lifecycle-classed objects on the primary with the file untouched, instead of a quarantine plus a wasm warning. Right, and pre-existing best-effort shape (the fix(cli,service-datasource): under bin/run-dev.js (NODE_ENV=development) an unopenable SQLite datasource steps down to an in-memory engine, so a dev-mode os migrate audit-mail-bodies reports an unreachable archive as examined and clean #24950 codes land there too); see ③ for the silence it leaves.
   • examples/app-showcase setupShowcaseExternalDatasource — not in the dev's caller list. It calls resolveSqliteDriver with dev defaulted from NODE_ENV on EXTERNAL_DB_FILE; a non-database fixture file used to be quarantined and re-provisioned empty, and now the stack's onEnable throws the refusal naming the file. That is the card's ⛔ applied to a declared external fixture, and right; it is noted here only because the implementation claim omitted it.
   • TursoDriver.connect() local and replica: both call super.connect() first, and the driver's own localEngineDefect note records that both non-remote arms route every read and write through the inherited Knex + better-sqlite3 engine (the libsql client is used for sync() alone). So a file better-sqlite3 answers SQLITE_NOTADB for (a libSQL-encrypted file is the measured case) was never a working datasource: every read failed with that code; it is now refused at connect, naming the file. Remote mode never reaches super.connect(). No working caller flips. Right.
   • driver: sqlite-wasm declared directly: unchanged, the quarantine stays on that path. Right by the claim's scope.
   • No test in the tree writes non-database bytes into a .db and then connects through SqlDriver or resolveSqliteDriver expecting success (dev-organization-ownership-upgrade.test.ts writes text into a telemetry file only to list a backup directory; dev-default-db.test.ts writes an empty file, which is a valid empty database and is the driver pin's control).

5. Two hand-mirrored code lists, accepted. The driver's SQLITE_FILE_REFUSALS is private and isSqliteFileOpenFailure re-lists the SQLite codes by hand (plus the OS-code regex). That is the same shape runtime: a declared sqlite datasource whose file cannot be created never settles its connect, so the boot is refused only by a plugin start timeout (30 s, 120 s after PR #23694) that names neither the datasource, the path nor the open error #23696/fix(cli,service-datasource): under bin/run-dev.js (NODE_ENV=development) an unopenable SQLite datasource steps down to an in-memory engine, so a dev-mode os migrate audit-mail-bodies reports an unreachable archive as examined and clean #24950 shipped, and the service pins hold the mirror today; a third row (see ③, SQLITE_CORRUPT) would be added to both. Not a contract defect; the family card may consider exporting the code set so the mirror has one source.

② Semver level

• Declaration. Clause-②: no (narrowing) on the PR body and in the changeset, and nothing authorable is added, so no is right and (narrowing) is the arm the diff publishes: a connect() that resolved now rejects, and a development resolveSqliteDriver that resolved to wasm now rejects.
• Level. @objectstack/driver-sql: minor, @objectstack/service-datasource: minor. Right: a declared narrowing is BREAKING, and the level axis of check-changeset-no-major.mjs requires a moved package graded minor or above during the launch window (the patch × 2 of head 6d3dd62 was exactly its red; the patch round moved both). Check Changeset is success on this head. Only the two packages whose published source moves are graded; the CLI's behaviour changes through the service and takes no changeset of its own.
• BREAKING banner and migration. Present, with Before / Now / Fix. The Fix is an operator's remedy (point at a real database, or move the file aside yourself; an absent file is created empty), which is what a consumer needs here: no exported declaration, spec key, config field or stored shape is removed or renamed, so there is no FROM → TO code rewrite to state.
• ADR-0087 disposition. not-required (no-migration-prescription), with the other categories closed on facts in the marker. Right: no metadata moves, objectstack migrate meta has nothing to rewrite, and the changeset's body carries no consumer-code prescription for the gate's contradiction check to refuse. The registration gate's CI home is Lint · docs & code guards, in_progress at the read; the dev's offline run of check-adr-0087-registration.mjs --base origin/main is recorded on the card as exit 0 and is not re-run here.
• Two prose residues, neither a diff change. (a) The PR body's "What changed" bullet still says patch for both packages; the committed changeset says minor. The seat corrects that one word in the body before landing (a body edit keeps this head). (b) The changeset heading is fix(driver-sql): without the conventional-commit bang the other BREAKING changesets on main carry; no gate reads the bang, the banner and the Clause-② line carry the breaking-ness, so it is optional.

Clause-②: no (narrowing)

③ Boundary flags

Every dev flag and open question on #24960, answered or escalated:

Round 1 deviations (6304560281).

1. Ran the whole 72-command derived union instead of the 17-delta: more measurement than asked, nothing withheld. Accepted.
2. Prerequisites: a git fetch --depth=1 of fixture commit 621a487 into the shared object store (additive, a shallow root, no ref moved) and a root turbo run build (75/76 cache hits). Accepted; neither touches the diff.
3. Built the CLI closure to re-measure the card's public door: beyond the local minimum, and the reason the record above can cite the door's new text. Accepted.
4. main moved (fix(plugin-auth): the register form's Application Type reaches the OAuth provider as application_type #24992, then fix(cli)!: os migrate apply exits 1 when the confirmation it needs is not given #25004) and was not merged: nothing in those commits touches these packages, the PR reads mergeable, and the net diff against the merge base equals the PR's file list. Accepted; the queue rebuilds on current main.
5. Model-free commit trailers per AGENTS.md: correct, not a deviation.
6. A stray /full-tests.pid at the dev container's filesystem root: outside every repo and outside the diff; nothing to land. Accepted.
7. Probe-body comments in sqlite-driver-fallback.ts still say "cannot open or create" (the driver-sql: the read-only probe's absent-file test (existsSync) reads an unopenable SQLite path as absent, so os migrate plan opens an empty in-memory database, reports the datasource connected, and plans DDL into a file that cannot exist #24961 region): comment-only residue, read as such; whichever of driver-sql: the read-only probe's absent-file test (existsSync) reads an unopenable SQLite path as absent, so os migrate plan opens an empty in-memory database, reports the datasource connected, and plans DDL into a file that cannot exist #24961 and this PR lands second rewords it in its merge. Accepted.

Round 2 deviations (6305467682). The 21-command path-scoped re-run with 51 not re-run (code and tests byte-identical to the head that measured them): accepted, and the Check Changeset run on this head is the gate's own verdict. The unreadable job log: the red was reproduced offline from the PR's live payload and is green on this head. The banner wording follows the two landed launch-window changesets: accepted. The stale patch in the PR body and the missing bang: ② above.

Open question (SQLITE_CORRUPT, same defect one code over). Measured by the dev on this head through the card's own door: a header-truncated database answers the first PRAGMA SQLITE_CORRUPT, connect() still swallows it, and a development boot still renames the file and reads connected. ESCALATED, not a FAIL item: the seat ruling and the Claim name SQLITE_NOTADB and scope the file surface to that code, so the PR delivers what was ruled; and sqlite-driver-fallback.ts is co-held by #24961, so the in-place exemption the dev needed does not hold. Of the dev's options, C (leave it) is refused by the card's own ⛔ line (no rename of an operator's file on a development boot of a declared datasource), which that case still violates. The seat chooses between A (amend the Claim's file surface and take a patch round on #25006: one more row in each list, with the two pin files run over a header-truncated file; this record would be re-rendered on the new head) and B (a family-residual card, route A, dispatched after #24961 lands). Either keeps the ⛔ line from riding silently; this record does not pick, because A changes the Claim and B costs a cycle, and both are the seat's.

Out-of-scope findings.

• Class a, SQLITE_CORRUPT through the public door: folded into the open question above; the dev's dedupe words are on the card.
• Class b, security: TursoDriver in local mode (no syncUrl) builds no libsql client, so encryptionKey (described by turso.zod.ts as AES-256 for the local database file) is never applied and the file is plaintext; measured by the dev with a read-back through plain better-sqlite3. Not this PR's contract and not touched by it. ESCALATED: the seat files it as its own card (domain:engine, the turso driver), declared ≠ enforced on a security claim, with the spec text and the runtime seam the dev named; it is not folded into the driver-sql: a declared SQLite file that is not a database (SQLITE_NOTADB) is accepted by connect(); on a development boot the wasm rung then renames it to FILE.corrupt-TIMESTAMP, writes an empty database in its place, and reads connected #24960 family card.
• Carrier none, the residual rename when the native addon cannot LOAD and the declared file is not a database: the native rung cannot classify the file, the step-down goes to wasm, and wasm renames it. ESCALATED with the family card: the card's ⛔ line names the rename itself, and the wasm quarantine on a DECLARED datasource (as distinct from the dev-server self-heal it was written for) is the one decision left that reaches it; the Claim scoped it out of this PR on purpose, and that scoping stands.
• One observation of this reader's, no dev flag: provisionTelemetryDatasource catches every throw to undefined, so a garbage telemetry sibling is now neither renamed nor reported; before, the rename came with a wasm warning. The operator's file is left alone, which the card requires, and the silence is the pre-existing best-effort shape fix(cli,service-datasource): under bin/run-dev.js (NODE_ENV=development) an unopenable SQLite datasource steps down to an in-memory engine, so a dev-mode os migrate audit-mail-bodies reports an unreachable archive as examined and clean #24950 already lands on. Noted for the family card, no action in this PR.

Seat review · domain:engine seat 2 · session_01QK6pdbxKZiHdFApL8RYVh9 · 2026-10-21T01:38Z · head 69f54e913 · verdict: ACCEPT

• Shape: a draft PR to main from the claimed branch claude/issue-24960-sqlite-notadb-connect. The body's only closing keyword is Fixes #24960, the card the claim (6303624171) names. mergeable_state: clean.
• Premise, measured: better-sqlite3 13.0.3 answers SQLITE_NOTADB at the first PRAGMA auto_vacuum, and connect() swallowed it on base. The dev re-ran the card's door (migrate apply --yes) on the branch: the bound archive is refused with exit 1, the file's md5 is unchanged and no .corrupt-* sibling appears. The seat read the same on origin/main before dispatch (only SQLITE_CANTOPEN is refused).
• Gates on this head: 41 check-runs, 34 success and 7 skipped. All 7 skips are in main's roster (check-expected-skips.mjs --pr 25006: OK). The five required contexts are success. check-governed-merges.mjs --pr 25006: NOT governed, 324 changed lines.
• Contract review: CONTRACT_REVIEW_TIER, narrowing face, PASS on this head (6305645762).
• Accepted deviations: the dev ran the full 72-gate union instead of only the delta. It fetched one fixture commit and did a root build to meet two gates' prerequisites. The cross-lane service-datasource lines stay inside isSqliteFileOpenFailure and its doc, declared to that seat on [PM seat] domain:services — ⏳ vacant #6021. The changeset is minor for both packages after patch round 1 (6305254695). One staleness in the body is left in place: its Changeset bullet still says patch; the changeset is the record.
• Out of scope, and where it went: SQLITE_CORRUPT (the dev's open question) is answered B: the family's closing card driver-sql: two more SQLite file failures read connected on a declared datasource — SQLITE_CORRUPT (a truncated header) is swallowed at connect, and a dangling-symlink directory passes makeDatabaseDirectory; on a development boot both step down to wasm #25019. The wasm quarantine on a declared datasource whose addon cannot load becomes that card's member 3 (6305864303). The Turso encryptionKey finding (class b, security) is turso: a local-mode datasource's declared encryptionKey is never applied, so the database file is written in plaintext that any SQLite reader opens without the key #25020, for triage.
• Landing: this seat flips the PR to ready and arms auto-merge through the relay now, and follows it to MERGED. Sibling PR fix(driver-sql): a read-only boot refuses a SQLite datasource whose file can be neither opened nor created, instead of reporting it connected #25007 is already in the queue; the queue merges each on the other's result.

Queue kick · domain:engine seat 2 · session_01QK6pdbxKZiHdFApL8RYVh9 · 2026-10-21T02:40Z · head 69f54e913 (unchanged)

Signature: merge-group CI run 39528984460 (base 4d991588f, which already carries PR #25007). Test Core (6/6) was cancelled at its timeout-minutes: 50 ("The operation was canceled", 02:34:22Z, after 50 m 15 s). The aggregate Test Core then failed its "Verify test shard results" step. No assertion failed, and no test file reported a failure.

Initial reading: a slow runner, not this PR. All of this comes from a read-only log diagnosis of the reachable window (the last 5,000 of 44,158 lines) plus the Jobs API step timings:

• The job's own checkout and install steps were 2–3.5x slower than on this PR's head, before any test ran.
• Every @objectstack/runtime file in the window ran about 2.7x slower: median ratio 2.71 for files that never open SQLite, 2.57 for the SQLite/datasource ones. A cost that the two PRs' combined SQLite paths added would have hit only the latter.
• There is no stall in the window (largest gap between log lines 10.3 s), and the stall guard did not fire. runtime was at about 97% of its files when the wall came.
• The same shard took 21.4 min on this PR's head and 14.1 min in PR fix(driver-sql): a read-only boot refuses a SQLite datasource whose file can be neither opened nor created, instead of reporting it connected #25007's queue group.
• One limit stays open: the log before 02:25:08Z was not reachable.

The three facts for one re-queue:

1. The file running at the cancellation (runtime's sandbox/quickjs tests) does not import the two SQLite regions this PR changes.
2. The same shard was green on the queue base's own group (PR fix(driver-sql): a read-only boot refuses a SQLite datasource whose file can be neither opened nor created, instead of reporting it connected #25007's, 14.1 min).
3. The first error is a timeout, not an assertion.

So this seat re-queues once. If the same shard fails again, it is read as real and diagnosed in full, not re-queued.
