engine: the one-definition-of-multi-valued invariant reaches packages/objectql and driver-turso — the domain:engine half of #18199's ruling

[os-support-ai]

The domain:engine half of #18199's ruling — execution, ⛔ not a fresh decision

Filed by the domain:cli execution PM seat (#6024) at #18199's landing, per triage's routing 5681445124, which split that card and named this half explicitly:

A child card carries the objectql + driver-turso sites into domain:engine with Blocked-by: pointing here, so that lane executes a ruling rather than re-deciding one.

The ruling this card executes — ⛔ not re-openable here

#17469 (maintainer ruling, director batch #128 item 5, option 1′) established one definition of 「is this field multi-valued」: isMultiValueField in packages/spec, with storage following it.

⭐ The domain:cli half has now LANDED, so the ruling is no longer theoretical — it is the tree's behaviour on main:

• PR fix(cli): the one-definition-of-multi-valued invariant reaches os generate — the CLI half of #17469 #18392 → squash 7c8d6d9895d2b31954a4a69a7c26788eaa6c286a, verified by content on origin/main (declaredMultiValued present in packages/cli/src/commands/generate.ts), ⛔ not from a merge event.
• All five field.multiple reads in generate.ts now route through one seam that calls the spec predicate, and the three in-tree comments that declared the losing authority were rewritten rather than left standing.

⇒ Blocked-by: is already satisfied — this card is dispatchable now.

The sites — the counts are triage's, ⛔ re-derive before acting

package	files (triage's count, 5681445124)
packages/objectql	11
packages/drivers/driver-turso	1

The two the original card named by line (⚠️ line numbers drift; re-measure):

• packages/drivers/driver-turso/src/remote-transport.ts:2435 — if (field.multiple) return 'TEXT', the column type
• packages/objectql/src/engine.ts:4741 — return field.multiple === true ? marked : marked[0], and :13584 — const multiValued = fdef.multiple === true

⚠️ What a taker owes first — the premise is per-site and FALSIFIABLE

Verbatim from the parent card:

does this site read field.multiple to mean "is this value multi-valued"? A site reading it for a different question is ⛔ not covered. That premise held for 18 driver-sql sites and failed for 3 (message interpolations that echo an author's declaration rather than deciding anything). ⛔ Do not align a site because it matches a grep.

⭐ Two measured precedents for the exclusion side, both worth reading before you start:

1. driver-sql isJsonField and spec isMultiValueField disagree for master_detail / tree / text + multiple: true, so a consumer using the spec predicate to shape a query gets a 400 #17469's own round excluded 3 of 21 driver-sql sites as interpolations.
2. [finding] the one-definition-of-multi-valued invariant #17469 restored stops at the driver-sql package boundary — os generate migration still emits JSONB where the driver now emits varchar (#14829 in reverse) #18199's round excluded packages/runtime/src/action-execution.ts:1279 — it constructs a descriptor (ADR-0104 D2 inheritance) and the one definition is already asked one frame down at packages/spec/src/data/field-value.zod.ts:570 (isMultiValueField(def) ? z.array(element) : element). Aligning it would have applied the predicate to its own output. ⇒ a reported exclusion with a reading is a correct outcome here, ⛔ not a shortfall.

⛔ packages/spec is READ-ONLY for this work — the predicate is the subject of the ruling, ⛔ not a landing site. Anything needing a spec change belongs to the domain:spec seat.

Grading provenance, stated so it can be corrected

• domain:engine is triage's own routing (5681445124), carried here verbatim, ⛔ not this seat's judgement.
• priority:p2 is inherited from the parent [finding] the one-definition-of-multi-valued invariant #17469 restored stops at the driver-sql package boundary — os generate migration still emits JSONB where the driver now emits varchar (#14829 in reverse) #18199 (triage-graded p2 · Bug). ⚠️ This seat does ⛔ not grade; the triage seat should re-grade if the engine-side blast radius differs.

Branch: claude/issue-18408-multi-valued-invariant-objectql-turso
Worktree: objectstack-issue-18408
Domain: domain:engine
Seat: domain:engine#1
File surface: packages/objectql/src/ · packages/drivers/driver-turso/src/ (stop on breach; explain in the report)
Container & model: M, mode:subagent, model: opus (default judgement tier) — quoting this dispatch's own dispatch-gates.mjs --tier: 「Model tier — no path-derived mandate … The tier stays the PM's per-card judgment call (floor sonnet · default opus · ceiling fable).」 ⇒ default judgement tier: the card's whole substance is a per-site falsifiable premise with two measured precedents for excluding sites, so the work is judgement, ⛔ not a grep-and-replace.
Clause-②: no
Thread-read: none
Serial constraints cleared: Both declared packages are FREE. The two cards that held them landed and were verified by content on origin/main — #18637 (packages/objectql/src/hook-wrappers.ts) at 922c755888 and #18630 (packages/drivers/driver-sql/) at 32be735e5b. The two PRs still in review are disjoint: #18645 (packages/core/src/security/) and #18649 (packages/drivers/driver-sql/ — its vitest config and one new reporter file, read from get_files, ⛔ NOT sql-driver.ts). In-flight devs at claim time: 0.

Blocked-by: is satisfied — re-measured, ⛔ not inherited

premise	reading
the domain:cli half landed	✅ declaredMultiValued present 17× in packages/cli/src/commands/generate.ts on origin/main
⭐ dark control, same file, same instrument	0
isMultiValueField exists in packages/spec	✅ present
named site 1	✅ driver-turso/src/remote-transport.ts:2435 — if (field.multiple) return 'TEXT'
named site 2	⚠️ objectql/src/engine.ts:**4759** — the card says :4741. The line drifted by 18. Located by content, as the card itself warns.

⚠️ The site COUNT does not reproduce, and the card told you to re-derive it

Triage's count (5681445124) is packages/objectql = 11 files, driver-turso = 1.

This seat's re-derivation on origin/main, excluding *.test.ts: packages/objectql = 2 files, driver-turso = 1 (matches).

⇒ ⛔ The seat is NOT asserting triage is wrong. The gap is most likely a different population — sites vs files, or tests included — and this seat did not resolve it. ⭐ But the card's own instruction is 「the counts are triage's, ⛔ re-derive before acting」, and it is right: establish your own population, state what you counted (files or sites, tests included or not), and report both numbers against triage's. A count you cannot reproduce is the first thing to reconcile, ⛔ not the last.

Zone 1 — the ruling, ⛔ not re-openable

#17469 (maintainer, director batch #128 item 5, option 1′): one definition of 「is this field multi-valued」 — isMultiValueField in packages/spec, with storage following it. The domain:cli half has landed, so this is the tree's behaviour, ⛔ not a proposal.

Zone 2 — ⭐ the premise is PER SITE and is the whole job

Verbatim from the parent card, and this is what you are being paid to do:

does this site read field.multiple to mean 「is this value multi-valued」? A site reading it for a different question is ⛔ not covered. That premise held for 18 driver-sql sites and failed for 3 (message interpolations that echo an author's declaration rather than deciding anything). ⛔ Do not align a site because it matches a grep.

⭐ Two measured precedents for the exclusion side — read both before you start:

1. driver-sql isJsonField and spec isMultiValueField disagree for master_detail / tree / text + multiple: true, so a consumer using the spec predicate to shape a query gets a 400 #17469's round excluded 3 of 21 driver-sql sites as interpolations.
2. [finding] the one-definition-of-multi-valued invariant #17469 restored stops at the driver-sql package boundary — os generate migration still emits JSONB where the driver now emits varchar (#14829 in reverse) #18199's round excluded packages/runtime/src/action-execution.ts:1279 — it constructs a descriptor rather than deciding multi-valuedness.

⇒ ⚠️ A round that aligns every match has almost certainly got it wrong, because two prior rounds each found exclusions. Report your exclusion list and the reason for each — an empty exclusion list is a claim that needs its own evidence, ⛔ not a default.

  "summary": "Executed #17469's one-definition ruling in the two declared packages: every read of the raw `multiple` flag now asks `@objectstack/spec`'s `isMultiValueField`. objectql routes its three sites through one local seam (`declaredMultiValued`) and record-validator's select/radio gate became the negation of its own multi-value branch's predicate; driver-turso's `RemoteTransport.mapFieldTypeToSQL` short-circuit asks the predicate, so that driver's two transports stop declaring one field's column in two storage classes. The three in-tree comments that declared the losing authority were rewritten. `packages/spec` was not touched. The card's body is intact (no sanitizer truncation); the newest `Claim:` (5714317039) names this branch; assignee was already set by the PM and was not written.",
  "population_and_count_reconciliation": "MY POPULATION: every READ of the field-level `multiple` flag in non-test source of the two declared packages, located by content (`.multiple`, bracket access, destructuring, plus a full word sweep of `multiple`) = 5 sites in 3 files. TRIAGE'S 11 REPRODUCES EXACTLY as SITES (matching LINES), not files: at triage's own ref 827cacbf4b with triage's own declared predicate set (isMultiValueField / field.multiple / .multiple ??), counting matching lines over the WHOLE package (tests and CHANGELOG.md included) gives cli=18, objectql=11, runtime=1, driver-turso=1 — all four cells match triage's table; the file reading gives 6/4/1/1 and matches none. So the gap is a mislabelled column (sites, tests included), NOT an error in triage's work. Two consequences: (a) 10 of triage's 11 objectql lines already ask the spec predicate or are CHANGELOG prose — only engine.ts:4741 (today :4759) is a raw read; (b) triage's predicate set MISSES two raw reads spelled `fdef.multiple` (engine.ts:13168 and :13602), so a taker working from that grep alone would have shipped half the card.

The two authorities cannot disagree at that site today, so aligning it changes no behaviour on any input — it is NOT one of the four divergences. Aligned anyway because the line is the exact complement of the isMultiValueField(def) branch twelve lines below and the equality holds only while packages/spec keeps those two types where they are; two authorities for one dispatch is the drift the ruling ends.

⭐ The count reconciliation — this is the round's best piece of work

The dispatch said the seat could not reproduce triage's 「objectql = 11」 (it counted 2 files), explicitly did not claim triage was wrong, and made reconciling it the first task. The answer:

Triage's 11 reproduces EXACTLY as SITES (matching LINES), not files — at triage's own ref, with triage's own declared predicate set, counting over the whole package including tests and CHANGELOG.md: cli=18, objectql=11, runtime=1, driver-turso=1. All four cells match. The file reading gives 6/4/1/1 and matches none.

⇒ ⭐ A mislabelled column, ⛔ not an error in triage's work. Exactly the resolution the dispatch hoped for and refused to presume.

And the two consequences are why the reconciliation was worth demanding, ⛔ not bookkeeping:

• (a) 10 of triage's 11 objectql lines already ask the spec predicate, or are CHANGELOG prose. Only one is a raw read.
• (b) ⚠️ Triage's predicate set MISSES two raw reads spelled fdef.multiple (engine.ts:13168, :13602). ⇒ A taker working from that grep alone would have shipped half the card.

⭐ Had the seat accepted the number it could not reproduce — or, worse, asserted triage was wrong — neither consequence would have surfaced. A count you cannot reproduce is the first thing to reconcile, not the last.

The per-site premise was applied, and the exclusions are reasoned

Five sites aligned, each with the divergence named (not merely 「it matched」): the option-derived insert default (measured to throw VALIDATION_ERROR pre-fix), the dependents probe and cascade multiValued (both divergent for master_detail + multiple), and RemoteTransport.mapFieldTypeToSQL — where the same driver's two transports declared one field's column in two storage classes, chosen by which URL the deployment holds. ⭐ That last one is a real defect the card did not name.

Exclusions carry reasons, and include an explicit precedent check: 「nothing here CONSTRUCTS a descriptor the predicate is asked of one frame later (#18199's shape) and nothing interpolates the flag into a message (#17469's three)」. ⇒ The dispatch's warning that 「an empty exclusion list is a claim needing its own evidence」 was answered with a populated one.

⛔ Seat ruling on the near_exclusion — it STAYS

record-validator.ts:824 was aligned while the dev stated plainly that it is not one of the four divergences: its own type gate dominates, so isMultiValueField reduces there by construction to multiple === true and the two authorities cannot disagree today. It offered a two-line revert.

Ruling: keep it. The dev's own reason is the right one and this seat adopts it: the line is the exact complement of the isMultiValueField(def) branch twelve lines below, and the equality holds only while packages/spec keeps those two types where they are. ⇒ Leaving one dispatch with two authorities is precisely the drift #17469 exists to end, and 「it cannot diverge today」 is a property of today's spec, ⛔ not of the code.

⭐ Recorded as a seat ruling with a veto window, ⛔ not as silent acceptance — the dev handed the judgement back rather than burying it, which is why it gets an answer.

Verification

• Ablation with on-disk proof: the three source files restored to pre-fix content with the tests left as written; anchors declaredMultiValued 10→0 and isMultiValueField 3→0; mutated run 3 failed / 2 failed across the two packages; restore proven byte-identical by git hash-object against each HEAD blob (3/3) with git diff HEAD empty.
• ⭐⭐ Three of the eight new assertions stay GREEN under the mutation, and say so in their own bodies. ⇒ The dev measured the strength of its own tests and wrote the weakness into the file rather than letting a reader assume all eight bite. That is rarer and more valuable than a clean ablation.
• Live PostgreSQL run because driver-turso inherits from SqlDriver: 186 files / 3315 tests, exit 0 — with a positive control that the live cells really ran (a timezone test passing with OS_TEST_POSTGRES_URL set and skipping without it, same tree). ⛔ MySQL left to CI, ⛔ mysql-server not installed.
• Repo-wide pnpm lint in full, so ⛔ no narrowing claimed. Gates: 65 derived, 63 run, 2 NOT-MEASURED (exit 3), 0 UNRUN, one count on the final head.
• ⭐ check:cross-package-test-inputs was red at the first head and green on the final head after merging origin/main, because fix(gates): judge a cross-package walk root against the index, not the working tree #18641 landed. Named, ⛔ not chased, ⛔ not twinned — and it is the fourth independent measurement of [finding] check:cross-package-test-inputs exits 0 or 1 on the same commit depending on whether a dist/ exists — and lint.yml runs it with no build ahead of it, so CI only ever sees the blind leg #18621, now recorded there as evidence the cause is discharged.

Findings

⏹️ Three noted, not filed, each with a named carrier — an unreachable case 'formula', a duplicated default expression, and ⭐ the triage-table observation itself (「labels its column 'files' while the numbers are matching LINES, and its predicate set misses the fdef.multiple spelling」). The last is correctly not filed: it is a reading of one comment, ⛔ not a reproducible defect, a contract violation or an authoring trap. Its named carrier is the triage seat, next time it counts sites for a split — and this ACCEPT is where that reaches them.

mcp_calls 0 · REST writes 2. ⛔ No label was written, and none was owed — this PR publishes, so skip-changeset would have been wrong. ⛔ No denied-roster tool was called.

⇒ Ready + auto-merge (SQUASH). This seat follows it to MERGED.

Landing reconciliation — PR #18668 is MERGED; this card is closed out.

domain:engine execution seat, session_01CqmCgU5RGDoJYhHUMVp2af, 2026-09-17T15:30Z. ⛔ Every criterion below is command output, not the merge event's echo.

criterion	reading
squash commit	ef67b47afb26a3534da6b27dcc4d7a9912954d97
parent count	1 (6dfa3ea772) ⇒ genuinely a squash. ⛔ Not read off the auto-merge echo, which reports merge in this repo and is non-diagnostic
content verification (⛔ not the merge event)	on origin/main: isMultiValueField = 3 in driver-turso/src/remote-transport.ts, declaredMultiValued = 10 in objectql/src/engine.ts — each equal to the "fixed" anchor count the reverse verification recorded
closed_by_pull_requests	total_count 1, only #18668 ⇒ ⛔ no card was silently closed by a body keyword
label residue	pm:dispatched stripped via label-write.mjs, read back; this card now carries priority:p2 · domain:engine

⚠️ That label strip is a step landing-rule B writes out, ⛔ not optional housekeeping. GitHub closes a Fixes card for you; the label does not follow it down. Left hanging, a card delivered an hour ago counts as in-flight in every label:pm:dispatched lane sweep from here on. ⇒ Done in the same action, ⛔ not deferred to the next patrol — this round already had two green PRs found unlanded by the hourly Routine rather than by this seat, and the same laziness does not get a third instance.

The assignee stays, per the state model: it records who delivered the card, ⛔ it is not an in-flight signal.

⇒ Card final state completed, with zero residue. The three noted, not filed items in the ACCEPT each carry a named successor — the unreachable case 'formula' and the duplicated default expression go to whoever next edits that mapper; the observation about triage's column header goes to the triage seat — so ⛔ no new card is owed.

_{⚠️ Correction, same act: this comment was first posted in Chinese, which SKILL.md:99 allows only for the four named channels (maintainer quick-read, round report, ruling quotations, four-axis analysis). A landing reconciliation is none of them. Re-issued in English; ⛔ nothing in the readings changed, and the error is recorded here rather than erased.}
