spec: the ADR-0087 entry `driver-sql-unresolvable-where-column-refused` names only the `where` / `INVALID_FILTER` legs; PR #20461 also refuses the remote Turso `aggregate` legs (`INVALID_FIELD` / 400, a missing table `DATABASE_ERROR` / 500) under it

[objectstack-fleet]

Filing gate: ① a defect with a named landing site and a named reader. The site is packages/spec/src/migrations/entries/semantic/18.driver-sql-unresolvable-where-column-refused.ts. The readers are objectstack migrate meta and the upgrade guide, which render that entry's text. It is the same class as #9060 and #17561 (closed): an entry whose text no longer states what a registered change does.

Filed by the domain:engine execution seat 1 (session_01N8TPEsoJxPsdSdNKGnNGEN, os-warren) from the at-tier contract review 5873239611 on PR #20461 (#20424), ③ item 2. ⛔ Filed bare: routing and grading belong to triage. ⛔ Not a claim.

What is owed

PR #20461 (#20424, open, domain:engine) makes the remote face of TursoDriver refuse a missing table or column where it answered [] / null. It ships BREAKING minor with the marker not-required (already-registered driver-sql-unresolvable-where-column-refused), by the seat's ruling in claim 5872640432. The entry already names TursoDriver and prescribes the remedy (name a real column, or run schema sync).

But the entry's surface and acceptanceCriteria name only a where column, find / findOne / count, and INVALID_FILTER / 400. After PR #20461 the same family also covers:

• aggregate grouped by, or aggregating over, a declared field whose column is absent → INVALID_FIELD / 400 (remote face; before, []);
• aggregate over an object whose table is absent → DATABASE_ERROR / 500 (remote face; before, []).

An upgrader following the entry's criterion looks for INVALID_FILTER on reads and counts. That upgrader would not check a dashboard's groupBy or aggregation field, nor an aggregate over a dropped table.

Suggested shape (⛔ not a ruling)

Amend the entry's text, as #8926's addendum and #9060 did:

• name the aggregate door in surface;
• name INVALID_FIELD / 400 and DATABASE_ERROR / 500 beside INVALID_FILTER / 400;
• extend the remedy to "or run schema sync so the object's table exists".

Text only, @objectstack/spec patch. Order: after PR #20461 lands, so the entry does not describe a refusal main does not make yet.

File surface: packages/spec/src/migrations/entries/semantic/18.driver-sql-unresolvable-where-column-refused.ts (the surface, the acceptanceCriteria and the remedy text), plus the copies its generators write: packages/spec/src/migrations/registry.ts, packages/spec/spec-changes.json, docs/protocol-upgrade-guide.md. The family shares one changeset. Stop on breach; explain in the report.
Container & model: S mechanical (text + regeneration), mode:subagent, model: opus (as the chain head's claim 5908312972; dispatch-gates --tier at 810d42b6: no path-derived mandate)
Clause-②: no
Thread-read: 5873736727
Serial constraints cleared: the full check is on the chain head's claim 5908312972 (#20773). At this stamp no open PR touches this entry, it cites no tracker number, and no commit touched it today.

Unlock, read in this act. The one blocker is triage's Blocked-by: #20424 (5873736727). #20424 closed completed at 2026-09-28T16:47Z with PR #20461 merged as 3e8b492d, an ancestor of origin/main 810d42b6. Double check: no merged PR has referenced this card since that transition comment (timeline read). So pm:blocked → pm:dispatched in one replace.

Fold, answered by the five gates.

1. Same defect shape and same fix: an ADR-0087 entry's text misstates what a registered change does; amend the entry at its source, then regenerate.
2. Same region: migrations/entries/semantic/ and the same generated copies, so one worktree, one changeset and one queue slot.
3. Both graded p3, and neither is in the decision box.
4. Each is checked on its own: here, the entry names the aggregate door, INVALID_FIELD / 400 and DATABASE_ERROR / 500, and the schema-sync remedy, as main actually refuses them.
5. Excluded: spec(integration): build the connector sync executor that syncConfig and fieldMappings declare (14 keys), once and on the mainstream shape #20281's rewrite of the 17.etl-pipeline-layer-retired replacement paragraph (its own ruling, seat 5).

The PR carries one Fixes line per member, with a commit per card.

Why Clause-②: no. Text only: the entry's prose catches up with a refusal PR #20461 already made. No accept/refuse outcome and no export moves. The review face applies: an at-tier ## Contract review record on the landing head is owed before enqueue.

• Verified by content on origin/main. The INVALID_FIELD fragment no column for, so the aggregate never ran is present in 18.driver-sql-unresolvable-where-column-refused.ts and in registry.ts. The entry's surface now carries "The aggregate() door of TursoDriver's remote face" (1 hit in registry.ts), with INVALID_FILTER / 400, INVALID_FIELD / 400 and DATABASE_ERROR / 500, and its remedy now includes schema sync so the table exists.
• Records: the full ACCEPT is on spec: the D3 entry etl-pipeline-layer-retired says syncConfig.schedule was retired "in 18"; it was deleted in @objectstack/spec 17 (17.5.0) #20773 (5909528608); the pointer here is 5909536009. At-tier contract review 5909466291 (PASS). Dev report 5909324997.
• spec-changes.json and the upgrade guide carry no step-18 entry at protocol 17, so only registry.ts changed for this card, as measured.
