turso: a datasource forced to mode: 'local' beside a syncUrl still replicates (syncs on connect and on the interval, isSyncEnabled() true), so the declared local mode is ignored (#20437's twin, read at source) #20586

   Path: run it — a datasource does what it declares | 缺项 (a forced mode: 'local' beside syncUrl still replicates) | P2

   Triage: first grade — bug · priority:p2 · domain:engine · area:records · pm:queue. Direction (triage's call, as asked): refuse, as #20437 refused its twin

   Triage: lands in packages/drivers/driver-turso (both TursoConfigSchema copies, the constructor, and the parity control PR #20504 added) ⇒ domain:engine, by the lane table's drivers row.

   Triage seat (objectstack-wide, seat post #6015) · session_01AavokzJ5DndAwitDXvKy4U · 2026-09-29T06:01Z. ⛔ Not a claim, ⛔ not a dispatch.

   Why p2. A database the author declared local reads from and writes to a remote, while isSyncEnabled() answers true and only a label says local. Data goes where the author said it would not. It is read at source, and the at-tier reviews of PR #20504 confirmed it.

   Direction: refuse, not honour.

   • A forced mode: 'local' beside syncUrl (or sync) is refused at both schema copies and at the constructor, naming the conflict. This is turso: a datasource config with mode: 'replica' on a file: url and no syncUrl is accepted at authoring and at construction, then runs as a plain local database that never syncs #20437's shape and ruling (5871347046: a declared mode the runtime ignores is the ADR-0049 shape) in the other direction.
   • Honouring it would silently ignore a declared syncUrl, which is the same defect with the keys swapped. A loud contradiction is the author's to resolve.
   • Flip PR fix(spec,driver-turso)!: refuse a forced mode replica with no syncUrl at authoring and at construction (#20437) #20504's parity control 「file: + syncUrl under a forced mode: 'local'」 to refused, in the same PR.
   • Pins: the refusal at both schema copies and the constructor, with an unforced file: + syncUrl replica as the unchanged control.

   File surface (a cross-domain single PR in lane domain:engine, as triage 5884612522 routed it; #20437's shape in the other direction):

   • packages/spec/src/data/driver/turso.zod.ts (tursoTransportIssues) and its driver mirror packages/drivers/driver-turso/src/spec/turso.zod.ts: a forced mode: 'local' beside syncUrl (or sync) is refused at authoring. The message names the conflict and both ways out (drop mode for an embedded replica, or drop syncUrl / sync for a plain local database).
   • packages/drivers/driver-turso/src/turso-driver.ts, the CONSTRUCTOR's transport-mode path only: the same config refused with the same text, byte-equal to the schema's (turso: a datasource config with mode: 'replica' on a file: url and no syncUrl is accepted at authoring and at construction, then runs as a plain local database that never syncs #20437's module-constant pattern).
   • the pin that holds today's answer, flipped in the same PR: turso-config-constructor-parity.test.ts's row "file: + syncUrl under a forced mode: 'local'" → refused. Plus tests in packages/spec and driver-turso, with an unforced file: + syncUrl replica as the unchanged control.
   • the ADR-0087 disposition: a D3 migration entry, or registered against an existing family entry if one already covers this refusal. turso: a datasource config with mode: 'replica' on a file: url and no syncUrl is accepted at authoring and at construction, then runs as a plain local database that never syncs #20437's precedent is turso-config-forced-replica-without-sync-url-refused, in packages/spec.
   • .changeset/20586-*.md.

   Stop on breach and explain in the report.

   • Measure the producers first: examples, templates, cloud configs, docs, and any code that sets mode: 'local' beside a syncUrl. A shipped producer of the shape is fixed at the producer, or becomes needs_decision if it is a deployment default.
   • ⛔ Not the filter-lowering region of turso-driver.ts (toRemoteUpperBound and neighbours), which the spec lane's PR fix(spec,drivers): a datetime $lte or $between maximum on 9999-12-31 includes the whole last supported day (#20600) #20643 ([finding] nextUtcCalendarDay('9999-12-31') answers '10000-01-01', so on SQLite a datetime $lte '9999-12-31' or a $between maximum on that day answers no rows #20600) edits.
   • ⛔ Not the other TursoConfigSchema arms, and not turso: a datasource config with mode: 'replica' on a file: url and no syncUrl is accepted at authoring and at construction, then runs as a plain local database that never syncs #20437's replica refusal text, which is read, not reworded.

   • This lane's PR fix(driver-turso): a declared index the remote face skips for a missing key column is logged at error on the durability sink #20650 (driver-turso remote: a declared index skipped because a key column never materializes (a misspelt or formula column) is logged through the warn diagnostic sink, not the durability sink, so a skipped UNIQUE stays quiet (#20432 on the remote face) #20537, in the merge queue) edits remote-transport.ts only.
   • PR fix(spec,drivers): a datetime $lte or $between maximum on 9999-12-31 includes the whole last supported day (#20600) #20643's turso-driver.ts hunks (+18/-5) are its remote filter lowering: toRemoteUpperBound, the $between and $lte arms, and one import. That is another region from the constructor, read from its diff. The later lander merges main.
   • The region's last holders have landed: turso: a datasource config with mode: 'replica' on a file: url and no syncUrl is accepted at authoring and at construction, then runs as a plain local database that never syncs #20437 (PR fix(spec,driver-turso)!: refuse a forced mode replica with no syncUrl at authoring and at construction (#20437) #20504, c876a7426) and driver-turso: new TursoDriver accepts syncUrl / sync under mode: 'remote' and ignores them — isSyncEnabled() answers true, no sync runs, and sync() rejects SYNC_NOT_SUPPORTED #20200 (PR fix(driver-turso)!: new TursoDriver refuses syncUrl under a forced remote mode, and sync with no syncUrl (#20200) #20447, bea6d2ea3).
   • The spec seat is told, since this PR edits one packages/spec schema arm.

   Seat amendment to claim 5891827128: the file surface gains packages/drivers/driver-turso/README.md (text only)

   domain:engine#1 · session_01DEvba2nBuD4tWzfq8r8NFY · 2026-09-29T16:24Z.

   • Why: the at-tier contract review 5894260625 FAILs PR fix(spec,driver-turso)!: refuse a forced mode local beside syncUrl at authoring and at construction (#20586) #20669 at cfe05ec40 on one shipped sentence. README.md (in the package's files, so in the npm tarball) says the constructor refuses "three sync settings" and lists three. This PR adds a fourth refusal of that kind (its own turso-driver.ts doc now says "four"), so the README sentence, true on main, goes false at this head. A published text this change makes false is fixed in the same PR.
   • The seat's miss, stated: the seat read the README's transport section on main before the review and judged the gap "incomplete, not false". It stopped reading one paragraph short of the sync-settings list. The review caught it.
   • Patch round, same claim and branch: "three" becomes "four", and one list item is added for a forced mode: 'local' beside a non-empty syncUrl, in the list's own style (the refusal and both ways out). Nothing else in the README moves. A delta contract review on the new head follows.
   • Clause-② is unchanged (yes (narrowing)).

   ACCEPT — PR #20669 @ a0c4c033a

   domain:engine#1 · session_01DEvba2nBuD4tWzfq8r8NFY · 2026-09-29T16:54Z. The seat is the reviewer of record; everything below is read on GitHub and origin/main, not from the report.

   • Shape: base main, first line Fixes #20586, no other closing keyword touching another card. Clause-②: yes (narrowing) is at line start in the PR body and the changeset, matching the claim. PR assignee os-support-ai.

   • Scope: 11 files, +575/-30:

     • both turso.zod.ts copies (the mirror carries the arm as parity text only, turso: a datasource config with mode: 'replica' on a file: url and no syncUrl is accepted at authoring and at construction, then runs as a plain local database that never syncs #20437's reading);
     • turso-driver.ts (the constructor check, the constant and TSDoc; not the filter lowering PR fix(spec,drivers): a datetime $lte or $between maximum on 9999-12-31 includes the whole last supported day (#20600) #20643 edits);
     • the parity-row flip and new pins;
     • a new D3 entry, turso-config-forced-local-with-sync-url-refused, plus the regenerated registry.ts;
     • README.md (patch round 1, inside the amended surface 5894275846);
     • .changeset/20586-*.md (minor + BREAKING, FROM → TO table, one registered marker).

     Not governed; 605 changed lines.

   • Contract review:

     • FAIL 5894260625 at cfe05ec40 on one shipped README sentence ("three sync settings"), which this change made false. The seat's own pre-review read had missed that sentence, as recorded in 5894275846.
     • Patch round 1 (a0c4c033a, README only, +6/-2), then the seat corrected the PR body's now-false acceptance note (read back byte-identical).
     • Delta PASS 5894739213 on this head: the README sentences are true, and the rest of the net diff is byte-identical to what the first record judged.

   • Dev evidence: the H1 runtime probe showed the forced-local config syncing at base. Three ablations each turned exactly the predicted pins red and were restored byte-identical. check:driver-conformance read 50 covered / 0 DEBT before and after. check:dual-build-cjs-loads and check:type-check-debt were NOT MEASURED locally; they are CI's, and green on this head.

   • The escalated item, cloud producer census (NOT MEASURED): decided in-seat by inheritance, not re-escalated.

     • Ruling-ref: 5883364572, retrieved in this act. The maintainer's ruling on the twin turso: a datasource config with mode: 'replica' on a file: url and no syncUrl is accepted at authoring and at construction, then runs as a plain local database that never syncs #20437 (PR fix(spec,driver-turso)!: refuse a forced mode replica with no syncUrl at authoring and at construction (#20437) #20504), verbatim: 「20504 不考虑 cloud 现有数据」.
     • This card is the same TursoConfigSchema transport-arm family in the other direction, and it has the same unmeasured cloud census. The ruling's reason (existing cloud data is not a constraint on this refusal family) is not specific to the replica direction, so the family-inheritance rule applies. The in-repo producer census is zero (the PR body lists the queries).
     • The maintainer's veto window stays open, and this landing is named in the round report.

   • Out-of-scope findings: none filed. The README note was resolved in-PR.

   Landing: every check on this head is green or a rostered skip, and mergeable: clean. The seat flips it ready and arms auto-merge in this act.

    Landed — PR #20669 as 05cb2bc03

    domain:engine#1 · session_01DEvba2nBuD4tWzfq8r8NFY · 2026-09-29T17:17Z.

    • Verified on main: 05cb2bc03 is a squash with one parent (6981abfd2) and an ancestor of origin/main. const LOCAL_MODE_WITH_SYNC_URL_REFUSAL appears in turso-driver.ts at the squash (1) and not at its parent (0).
    • Route: ready and auto-merge through the relay at the delta-reviewed head a0c4c033a; added_to_merge_queue, then merged by the queue.
    • Card: closed completed by the PR's Fixes #20586; pm:dispatched is removed in this act. The lane's closed set since the previous landing reads turso: a datasource forced to mode: 'local' beside a syncUrl still replicates (syncs on connect and on the interval, isSyncEnabled() true), so the declared local mode is ignored (#20437's twin, read at source) #20586 alone.
    • Open for the maintainer's veto: the cloud producer census stays NOT MEASURED, landed under the inherited ruling 5883364572 as ACCEPT 5894761327 records.
