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

Filing gate ①, class a, reach measured through a public door. Filed by the domain:engine seat 2 (seat post #20966, os-support-ai, session session_01QK6pdbxKZiHdFApL8RYVh9) from two dev reports of this seat's dispatches: #24960's (6304560281, open question 1 and out-of-scope finding 1) and #24961's (6304625148, out-of-scope finding 1). ⛔ Not a claim. Grade: triage's.

Reader (who acts): the domain:engine seat (packages/drivers/driver-sql), in one PR, with one line of packages/services/service-datasource/src/sqlite-driver-fallback.ts declared cross-lane to domain:services. It is serial behind PR #25006 (#24960) and PR #25007 (#24961): it edits the regions both of them change.

The family, enumerated (this card is its closing card)

"A SQLite file the declared datasource cannot use is classified by its own driver at connect, and never stepped down past":

SQLITE_CANTOPEN: 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, landed.
SQLITE_NOTADB (a file that is not a database): 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, PR fix(driver-sql): a SQLite file that is not a database fails connect() at once, naming it, and a dev boot no longer renames and replaces it #25006.
the read-only boot's unopenable path: 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, 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 card, member 1: SQLITE_CORRUPT (a header SQLite cannot read).
this card, member 2: a dangling symbolic link as the datasource's directory, on the boot that writes.
Noted, not a member (no public-door reach measured): a non-database file under a native addon that cannot LOAD still steps down to wasm, whose quarantine renames it. It lives in driver-sqlite-wasm, and PR fix(driver-sql): a SQLite file that is not a database fails connect() at once, naming it, and a dev boot no longer renames and replaces it #25006's Acceptance notes carry it.

Member 1: `SQLITE_CORRUPT`, measured at PR #25006's head `6d3dd6247`

reach: bin/run-dev.js migrate apply --yes, a declared archive datasource (driver: sqlite, one object bound) on a SQLite file truncated to its first 50 bytes:
- archive.db was renamed to archive.db.corrupt-1792539192447;
- an empty database was written in its place;
- datasource 'archive': connected, under the "native better-sqlite3 unavailable" warning; exit 0.
Mechanism: better-sqlite3 answers SQLITE_CORRUPT at the first PRAGMA auto_vacuum, which SqlDriver.applyAutoVacuumIncremental swallows. The probe's SELECT 1 fails as DATABASE_ERROR (cause SQLITE_CORRUPT), isSqliteFileOpenFailure does not classify it, and the step-down goes to wasm, whose open quarantines the file.
Expected: refused at connect, naming the file, in both modes, the file untouched. After PR fix(driver-sql): a SQLite file that is not a database fails connect() at once, naming it, and a dev boot no longer renames and replaces it #25006 that is one more SQLITE_FILE_REFUSALS row and one more code in isSqliteFileOpenFailure.

Member 2: a dangling-symlink directory, measured on `4b8f597ba`

reach: bin/run-dev.js migrate apply --yes, a declared archive datasource (driver: sqlite, one object bound) whose directory is a dangling symbolic link: datasource 'archive': connected, then the false step-down warning "native better-sqlite3 unavailable (ABI mismatch or not built) — dev using wasm SQLite", then exit 1 later.
Mechanism: makeDatabaseDirectory (packages/drivers/driver-sql/src/sqlite-database-file.ts) accepts mkdir's EEXIST on the link as a concurrent creator. better-sqlite3 then throws a code-less TypeError ("Cannot open database because the directory does not exist"), applyAutoVacuumIncremental logs it and connect() resolves. The probe steps down to wasm.
The runtime host already refuses this shape for the primary database (cli/runtime: a dangling symlink in the SQLite database directory's path fails os dev and os serve late, with a plugin-start error that names neither the file nor the directory (the two bounded-walk copies accept any EEXIST) #24090, standalone-stack-uncreatable-db-directory.test.ts). 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 read-only probe refuses it too, so on this one shape os migrate plan says failed while migrate apply says connected.
Expected: the writing boot refuses it at connect, naming the file and the link, as the read-only boot does after 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.

None covers a declared datasource's writing boot.
Control: "SQLITE_NOTADB not a database wasm quarantine" hit 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 first, so the channel answered.

Dedupe words: SQLITE_CORRUPT step-down quarantine · truncated header declared datasource renamed · dangling symlink makeDatabaseDirectory EEXIST declared datasource.

Family note · domain:engine seat 2 (seat post #20966) · session_01QK6pdbxKZiHdFApL8RYVh9 · 2026-10-21T01:16Z. ⛔ Not a claim, no label change.

One more shape for this card's enumeration, from PR #25007's contract review (6305566864, own flag 10), by code reading and NOT MEASURED: a dangling symbolic link as the database FILE itself (not its directory). The read-only probe answers ENOENT at the first stat, walks from the directory, and reads it absent. The writing boot creates through the link when the link's target directory exists, which is consistent, and answers SQLITE_CANTOPEN when it does not. Whoever takes this card measures it beside member 2 and either pins it or names it out of scope in the PR.

Family note 2 · domain:engine seat 2 · session_01QK6pdbxKZiHdFApL8RYVh9 · 2026-10-21T01:38Z. ⛔ Not a claim, no label change.

PR #25006's contract review (6305645762, ③) escalates the "noted, not a member" line in this card's enumeration, and this seat takes it into the card's scope as member 3, to be decided by measurement. When the native addon cannot LOAD and a declared datasource's file is not a database, the step-down goes to wasm, and driver-sqlite-wasm's quarantine renames the operator's file. #24960's ⛔ line names that rename itself. The quarantine on a DECLARED datasource, as distinct from the dev server's own self-heal it was written for, is the one place left that reaches it.

Whoever takes this card measures it with the #24950 suite's load-failure seam. If refusing it means changing what the quarantine does for a declared datasource, that change is the card's fork to report, not the dev's to choose. The same review also notes that the dev telemetry sibling catches every throw (a garbage sibling is now neither renamed nor reported). That is the pre-existing best-effort shape, and it is listed here only so the PR names it.

Claim: PM loop round 2 · 2026-10-21T03:28Z · p2, domain:engine (triage's grade). The SQLite file-failure family's closing card: SQLITE_CORRUPT swallowed at connect, a dangling-symlink directory accepted on the writing boot, and the wasm quarantine on a declared datasource whose addon cannot load. Both prerequisites have landed: PR #25006 (7f9961680) and PR #25007 (4d991588f).

File surface:

packages/drivers/driver-sql/src/sql-driver.ts, SQLITE_FILE_REFUSALS and applyAutoVacuumIncremental (member 1, SQLITE_CORRUPT).
packages/drivers/driver-sql/src/sqlite-database-file.ts, makeDatabaseDirectory: member 2, a dangling link refused on the writing boot, as probeAbsentSqliteDatabaseFile already refuses it on the read-only boot.
packages/services/service-datasource/src/sqlite-driver-fallback.ts, isSqliteFileOpenFailure. This is cross-lane, under the declaration on [PM seat] domain:services — ⏳ vacant #6021.
Member 3 (the wasm quarantine for a declared datasource whose native addon cannot load) is measured first. If closing it changes driver-sqlite-wasm's quarantine behaviour, the dev reports it as a fork and does not choose.
The dangling link as the database file itself (6305577138) is measured; the PR either pins it or names it out of scope.
Pins, and changesets.

Clause-②: no (narrowing): connects that resolved over a corrupt-header file or a dangling-link directory are refused. It owes a CONTRACT_REVIEW_TIER review before the queue.
Responsibility: driver-sql's connect and service-datasource's step-down move an operator's file aside on a development boot | none: PR #25006 covers SQLITE_NOTADB only, PR #25007 the read-only boot only | any declared SQLite datasource whose file is truncated or whose directory is a dangling link
Thread-read: 6305864303
Serial constraints cleared: the open PRs' file lists were read at this claim. None touches sqlite-database-file.ts, sqlite-driver-fallback.ts or the SQLITE_FILE_REFUSALS region. PR #24893 and PR #24940 (os-steve) hold other regions of sql-driver.ts.

Seat ruling · member 3 (the wasm quarantine) · domain:engine seat 2 (seat post #20966) · session_01QK6pdbxKZiHdFApL8RYVh9 · 2026-10-21T07:57Z · route A, inherited from #24960's route A. This is a seat ruling under PM discretion: the maintainer may overturn it on this card before member 3 is dispatched.

Input: the dev's fork report on this card, 6310958104 (open question 1, options A–D, measured; nothing in driver-sqlite-wasm changed by PR #25080).

Governing text:

This card's family line: "A SQLite file the declared datasource cannot use is classified by its own driver at connect, and never stepped down past".
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's route A (claim 6303624171): "on a development boot the operator's file is neither renamed nor replaced". It landed as PR fix(driver-sql): a SQLite file that is not a database fails connect() at once, naming it, and a dev boot no longer renames and replaces it #25006 (7f9961680).

Why it is inherited, not escalated. A new branch of a family inherits the parent's ruling together with its reason, unless that reason is measured to be peculiar to the parent branch. Here it is not.

The quarantine's own reason was a torn wasm image. The atomic flush (write, fsync, rename) has since closed that.
Its measured population is operator files on declared datasources only: (a) the development step-down with an addon that cannot load, and (b) an explicit driver: 'sqlite-wasm' datasource. Case (b) renames the file and reads available in development AND production.
So the parent's reason (never rename or replace an operator's file; refuse it at connect, naming it) applies unchanged. The dev's four axes point the same way.
No security boundary or destructive action is involved. The ruling stops a destructive action.

What it binds:

WasmSqliteConnection.open() refuses a file sql.js cannot read, in every mode. The refusal names the file and carries code SQLITE_NOTADB / SQLITE_CORRUPT. Nothing is renamed and no empty database replaces it. quarantineCorruptFile retires.
resolveSqliteDriver re-throws a wasm file refusal instead of stepping down to the in-memory rung.
The durability test's self-heal case becomes a refusal pin.
Clause-②: no (narrowing), with driver-sqlite-wasm and service-datasource at minor, BREAKING.
⛔ No option and no knob (B), no leaving it (C), no header sniff in the consumer (D).

Cost, named: a development server whose own wasm image is damaged no longer boots itself clean. The operator moves the file aside, and the refusal's prescription says how.

Order:

Member 3 is serial after PR fix(driver-sql): a SQLite database whose header SQLite cannot read, and a dangling-link directory on the boot that writes, fail connect() naming the file #25080, because both edit sqlite-driver-fallback.ts.
PR fix(driver-sql): a SQLite database whose header SQLite cannot read, and a dangling-link directory on the boot that writes, fail connect() naming the file #25080 switches to Part of #25019, because its merge must not close this card.
Member 3 is dispatched on this card once PR fix(driver-sql): a SQLite database whose header SQLite cannot read, and a dangling-link directory on the boot that writes, fail connect() naming the file #25080 lands. Its PR carries Fixes #25019.

Probe	Reading
PR #25080 (`Part of #25019`)	`merged: true`, merge commit `d6a5fa3ba`, through the merge queue
`origin/main`	`d6a5fa3ba fix(driver-sql): a SQLite database whose header SQLite cannot read, and a dangling-link directory on the boot that writes, fail connect() naming the file (#25080)`
queue branch	`gh-readonly-queue/main/pr-25080-*` gone
card	open (the `Part of` keyword did not close it)

Landed:

Member 1: SQLITE_CORRUPT at the first statement is refused at connect, naming the file.
Member 2: a dangling-link directory is refused on the writing boot.
The dangling link as the file itself (6305577138) is closed on the read-only boot.

The contract review is 6311414662 (PASS).

Left: member 3, the wasm quarantine. It is ruled and not dispatched. The seat's ruling 6311031589 is route A, inherited from #24960:

WasmSqliteConnection.open() refuses a file sql.js cannot read, in every mode, naming it, with nothing renamed or replaced. quarantineCorruptFile retires.
resolveSqliteDriver re-throws a wasm file refusal instead of stepping down to memory.
Clause-②: no (narrowing), minor for driver-sqlite-wasm and service-datasource. It owes a CONTRACT_REVIEW_TIER review and the full dogfood battery.
Its PR carries Fixes #25019.
The maintainer may overturn the ruling here before a seat dispatches it.

The serial constraint with PR #25080 is cleared by this merge. The measurement to build on is the dev report 6310958104 (H3: both doors measured).

Spun off and filed: #25084, the handle a refused connect keeps open, for triage.

State: pm:dispatched → pm:queue in this act, and the assignee is cleared. The seat that takes the card re-claims it.
