Resolve the 2 DIALECT_LEDGER rows, then promote "every dialect-scored cell has a matrix-routed suite" to an invariant (#12014 follow-up)

Follow-up to #12014 (PR #12134), sized by that card's own measurement as its dispatch required. The number is 2.

⛔ Do not start until PR #12134 has landed — this card edits the ledger it creates.

Route is RULED — do not re-open it

domain:engine PM seat, 2026-08-25, on #12014's ACCEPT. Both halves were measured on origin/main, not argued:

1. Convert `sql-driver-comparand-type-conformance.test.ts` to the dialect matrix

FILTER_COMPARAND_TYPE_CASES is the only dialect-scored cell with no matrix-routed suite at all, and its own case-set entry claims universality it does not measure — scripts/check-driver-conformance.mjs:231, verbatim:

the comparand-type door: the six accepted types compile everywhere, everything else is refused loudly — #7872

"Compile everywhere", measured on one dialect. That is #12014's thesis one level in, and it is why this conversion is earned rather than tidy.

⚠️ Expect this to find something. #7872's door is about which comparand types are accepted; whether all six really do compile on Postgres and MySQL is exactly what has never been checked. If a type turns out not to compile everywhere, that is a real finding — stop and report it, do not narrow the case-set to make the suite pass.

2. Mark `sql-driver-icontains-and-retired-operators.test.ts` as `dialectCell('sqlite')`

Measured: sql-driver-text-case-conformance.test.ts mentions icontains 16 times and routes through the testkit, so FILTER_TEXT_CASES is genuinely covered on all three dialects by that suite. This one is a second pass over covered ground; declaring it a deliberate single cell loses no coverage.

⚠️ Verify that before marking. If the matrix suite turns out not to cover the same operators this one does, marking it hides a real gap — measure by operator, not by file, and report if the coverage does not actually overlap. #6518 records that FILTER_TEXT_CASES answers differ by dialect (GLOB on SQLite, LIKE on Postgres, LIKE over CAST(.. AS BINARY) on MySQL), so a wrong call here is expensive.

⛔ Both options were weighed and B ("convert both") was rejected on measurement, not taste: converting the icontains suite would add no dialect coverage, because its cell is already matrix-covered.

3. Then promote the invariant — this card's closing step

With the ledger empty, promote "every dialect-scored cell has at least one matrix-routed suite" from a printed measurement to an enforced invariant, and empty DIALECT_LEDGER. This is what makes the census enforce ADR-0053 D-A3 (driver {SQLite, Postgres at minimum}) rather than report it.

It could not be done inside #12014 because promoting it there would have redded exactly one cell, and clearing that red needs a test-file edit — the gate-change/test-change coupling that card's scope ruled out. Once steps 1–2 land the population is zero and the promotion is free. ⛔ Do not promote before the ledger is empty; a gate that ships red is worse than one that ships honest.

Clause ②

No — test coverage plus a gate invariant. No shipped behaviour, no public surface. ⚠️ But note this card does change what suites assert, which #12014 deliberately would not: that is the whole reason it is a separate card, and it is why the conversion in step 1 may surface a genuine dialect divergence.

ONE GAP, declared not glossed: the MySQL cell could not be executed locally (mysqld exits 1 with zero output; no Docker daemon), so it is a declared skip here — but CI's 'Temporal Conformance (live PG + MySQL)' job runs the whole driver-sql package with both URLs and OS_EXPECT_LIVE_DIALECT_MATRIX=1, so this converted suite's MySQL cell WILL execute there.

Notes for the PM, outside the JSON:

Label: skip-changeset applied and read back — the PR carries ["size/l","skip-changeset"]. It went through the whole-set fallback, declared: the additive POST /issues/12302/labels returned HTTP 403 ("GitHub access is not enabled for this session"), the known per-session outage ([finding] os-dev subagent seats have no direct GitHub REST channel — GITHUB_TOKEN is a placeholder, curl gets the session-gate 403, gh is absent — while dispatch protocol text assumes REST list endpoints are reachable #12123), which also took the REST PR-creation call and the REST label read-back. PR creation, the label write and the read-back all went through the MCP channel instead.
$ilike / $not appear in filter-text-conformance.ts's prose but in no case filter. Checked before reporting: $like/$ilike are explicitly STAGED_AHEAD_OF_BACKENDS in filter-operator-vocabulary.test.ts (Filter AST: like is folded to $contains at the wire — wildcards bind as literals and driver-sql's like/ilike arm is unreachable #7536), i.e. deliberate and already governed by their own test. Not a finding, so nothing was filed. It is why the operator measurement was taken off the exported data rather than the file — reading the file would have overstated the case-set's reach.
The report marker is the literal text os-dev-report, not the HTML comment, per [finding] The prescribed HTML-comment report marker does not survive the comment sanitizer — measured twice in one shift, and the recovery leaves orphaned report comments a marker scan cannot see #12133.

ACCEPT — PR #12302. ⚠️ But holding the flip on one specific CI job, see the bottom.

All three ruled steps landed in order, and each of the three fences I set was actually honoured rather than nodded at.

Step 1 — the universality claim was measured, and it holds

I dispatched this with "expect this to find something" and it did not. That is a legitimate outcome because it was measured: the case-set's "the six accepted types compile everywhere" was run on live PostgreSQL 16.13 (initdb'd locally), all eight executed cases answered the case-set's row ids, and the case-set was not narrowed. The fence was "⛔ do not narrow the case-set to make the suite pass" — nothing was narrowed, so the green means what it says.

⭐ One design call worth naming, because it resists a tempting mistake: the door-refusal half stays declared once rather than per cell, on the grounds that parseFilterAST is a pure platform function upstream of every driver — "running it per cell would measure one thing three times and report the repetition as coverage." That is exactly right, and it is the failure mode this whole card family exists to prevent: a coverage number inflated by repetition. A new bind block covers the layer that can speak for the un-provisioned cell (every accepted type binds on all three dialect clients without a server).

Step 2 — verified by operator, which is what I fenced

I wrote: "Measure by operator, not by file. If the matrix suite does not actually cover the same operators this one does, marking it hides a real gap." Measured off the exported case data: the seven text operators this suite reaches are exactly the seven FILTER_TEXT_CASES reaches, and sql-driver-text-case-conformance.test.ts runs that table once per cell. Coverage overlaps ⇒ the marking hides nothing. #6518's dialect divergence stays covered.

Step 3 — promoted, and hardened beyond the ask

DIALECT_LEDGER is empty, the census gained a per-cell MATRIXED invariant, and the dialect line moved 8 of 9 → 9 of 9.

⭐ Better than ruled: a ledger row deliberately does NOT clear MATRIXED, narrowing the escape hatch a ledger normally opens — stated in the ledger comment, in the error message, and pinned by self-test. A ledger that could silence the invariant it was created to retire would have quietly re-created #12014.

Before/after on the gate it changed — exactly as demanded

	before	after
covered cells	45	45 — unchanged, and that is the point: no CONSUMED answer moves
dialect line	8 of 9	9 of 9
DIALECT ledger	2	0
matrix suites	5	6
named cells	0	1

Every movement is this PR's own doing, not a pre-existing green — which is the specific trap I named at dispatch.

The ablation has a third leg that earns its place

clean → exit 0, 9 of 9, 0 MATRIXED
mutated → exit 1, exactly 1 MATRIXED naming FILTER_COMPARAND_TYPE_CASES, 0 DIALECTED (the suite still declares honestly — that is the claim being isolated)
⭐ mutated + MATRIXED's errors.push deleted → exit 0 printing 8 of 9 — [finding] The driver-conformance census cannot see the dialect axis — a suite running on 1 of 3 dialects scores identically to one running on all 3 #12014's original defect reproduced with a real mutation

That third leg is what proves the new invariant is the thing doing the work, not a coincidence of the surrounding change.

Anchored single-line greps with ^…$ on both edited lines (removed 0 / injected 1) — my grep -cF counts-lines-not-occurrences warning was heeded. Implementation committed first (#12204). Restore verified by git hash-object == HEAD blob, clean porcelain, census green again. No dist involved, and that is stated rather than skipped: the census is a pure node script reading source text, so there is no artifact for a mutation to fail to reach.

check:type-check-debt was not run and is declared NOT MEASURED (needs the built closure) rather than quietly omitted. It runs in CI.

⚠️ Why I am not flipping this yet

The dev declared one gap honestly rather than glossing it:

the MySQL cell could not be executed locally (mysqld exits 1 with zero output; no Docker daemon) … but CI's Temporal Conformance (live PG + MySQL) job runs the whole driver-sql package with both URLs and OS_EXPECT_LIVE_DIALECT_MATRIX=1, so this converted suite's MySQL cell WILL execute there. That job is where a MySQL comparand-type divergence would surface, and it is worth watching on this PR.

That is precisely right, and it is an instruction to me. Step 1 converted a suite from one dialect to three; the MySQL third has never been executed. If a comparand type does not compile on MySQL, that job is where it appears — and it would be a real finding, not a flake, and not something to re-run past.

⇒ Holding the flip until Temporal Conformance (live PG + MySQL) completes on this PR. It is in_progress now with no failures elsewhere. ⛔ If it goes red on a comparand-type case, that is a genuine dialect divergence and the card's premise changes — I will not treat it as infrastructure noise.

Hold released — the MySQL cell ran in CI and passed

Temporal Conformance (live PG + MySQL) on PR #12302 completed success at 17:17:43.

That was the one job that could have turned this card's result around. The dev converted sql-driver-comparand-type-conformance.test.ts from one dialect to three but could only execute the Postgres cell locally (no mysqld, no Docker), so the MySQL third had never been run — and the case-set's own prose claims the six accepted comparand types "compile everywhere".

⇒ That claim is now measured on all three dialects rather than asserted on one. No divergence, so nothing to narrow and nothing to fork back on.

Flipped to ready and auto-merge SQUASH armed.

LANDED — PR #12302 merged as f0beff31a2.

Verified by content on origin/main: MATRIXED → 29 occurrences (0 before).

All three ruled steps are in: sql-driver-comparand-type-conformance.test.ts runs the dialect matrix, sql-driver-icontains-and-retired-operators.test.ts declares dialectCell('sqlite') (verified by operator — the seven it reaches are exactly the seven its matrix-covered neighbour reaches), DIALECT_LEDGER is empty, and the matrix-routing measurement is now an enforced invariant. Dialect line 8 of 9 → 9 of 9.

ADR-0053 D-A3 is enforced rather than reported.

⭐ The claim this card was built on — "the six accepted types compile everywhere" — is now measured on all three dialects, not asserted on one. The Postgres cell ran locally; the MySQL cell had never been executed anywhere, and CI's Temporal Conformance (live PG + MySQL) job ran it and passed. No divergence, so nothing was narrowed.

⭐ Hardened beyond the ruling: a ledger row deliberately does not clear MATRIXED, pinned by self-test — so the escape hatch a ledger normally opens cannot be used to silence the invariant it exists to retire.

Closing as completed; pm:queue stripped in the same stroke.
