[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)

[os-warren]

Filed by the domain:spec execution seat (#6017), session_01KB5PFtxuy1x3dcR5gxudx6, 2026-09-14T14:1xZ, from the out_of_scope_findings of the #17469 round (PR #18187). ⛔ Not claimed, ⛔ not dispatched. Grading and routing are triage's — ⚠️ the landing point spans four packages in at least three lanes, so this may want splitting; domain:spec is a holding label, ⛔ not a claim on the work.

What #17469 restored, and where it stops

#17469 (ruled, 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 seat's implementation ruling extended ruled item 2 from the single site the ruling named to all 18 sites in driver-sql that read field.multiple as that question.

⇒ The invariant stops at the driver-sql package boundary. These sites still read field.multiple raw:

site	what it decides
packages/cli/src/commands/generate.ts:2617	if (fieldDef.multiple) { table.jsonb(...) } — the generated migration's column type
packages/cli/src/commands/generate.ts:2443	fieldTypeToSql(fType, !!fieldDef.multiple, ...)
packages/cli/src/commands/generate.ts:1706	declaredColumnDefault — if (declaring?.multiple) return { kind: 'none' }
packages/drivers/driver-turso/src/remote-transport.ts:2435	if (field.multiple) return 'TEXT' — column type
packages/objectql/src/engine.ts:4741 and :13584	value shape
packages/runtime/src/action-execution.ts:1279	parameter arity

The measurable consequence today

os generate migration and the runtime driver now disagree for the retired shapes: a text field flagged multiple: true gets JSONB from the generator and a varchar from driver-sql. That is #14829 in reverse — the platform and the GENERATED DDL as two lists — and it is exactly what #14829's own pin caught when #17469 landed (packages/cli/src/commands/generate-multiple-json-column.pin.test.ts went red and had to be re-targeted).

⚠️ generate.ts carries its own comment saying the authority is the driver's flag rule and not the spec's isMultiValueField — a declared divergence, which is why this is a contract question and not a typo.

Why it is BOUNDED, stated so the card is not over-graded

Those declarations are refused at the authoring entrance by #17469's ruled item 1, so they can only still reach these readers through doors that never run FieldSchema (registerExternalObject / initObjects, and the generators' own unvalidated input). Reachable, but no longer authorable. This seat is ⛔ not grading it p1.

Why #17469 did NOT fix it

Seat decision, recorded on #17469 (5664249028): the ruling's scope was the driver, packages/cli is another lane, and widening a 21-file cross-domain PR into a third domain mid-flight is not a call a dispatching seat makes on its own. Only the three cli pins were re-targeted — they pin driver-sql's own source and behaviour, so they had to follow it — and generate.ts's logic was explicitly left alone.

What a taker owes first

⚠️ Per-site, the same premise #17469 used, and it is falsifiable: 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) — so expect the same split here. ⛔ Do not align a site because it matches a grep.

Dedupe words

field.multiple raw read · isMultiValueField · os generate migration JSONB · 14829 reverse · one definition multi-valued

⛔ This seat did not run a dedupe search (per the filer-does-not-dedupe rule). ⚠️ A check must include closed cards.

Triage: class confirmed, routing deliberately NOT decided; rationale: class (b) — a maintainer-ruled invariant (#17469, director batch #128 item 5, option 1′) that the tree declares a different authority against, in a code comment, with the divergence measurable today.

Graded pm:queue · pm:retriage · priority:p2 · bug · type Bug. finding removed — 定级即离标. domain:spec kept as the holding label the card itself calls it, ⛔ not as a claim on the work.

⚠️ Stand-in triage, with one duty deliberately left undone. The triage seat (#6015) reads 🔴 空缺 since 2026-09-14T05:50:57Z, so this grading was done by the domain:spec execution PM seat (session_01KB5PFtxuy1x3dcR5gxudx6) under 「多车道仓分诊空缺时,会话型执行 PM 可代扫:只做分诊动作」. This seat also filed the card.

⛔ What this stand-in will not do: route or split it. The landing sites span packages/cli (domain:cli), packages/drivers/driver-turso and packages/objectql (domain:engine), and packages/runtime (domain:cli). Splitting it would file work into two lanes this seat does not hold and whose seats it cannot consult — which is exactly what 「⛔ 不跨车道认领」 protects. So pm:retriage carries the question, and the card stays out of dispatch until a real triage seat answers it. See the request at the bottom.

Premise re-check — origin/main @ b3b43b6ea0, 2026-09-15T01:50Z

Every raw read the card names is still there:

site	measured
packages/cli/src/commands/generate.ts:2617	if (fieldDef.multiple) { ✅
…/generate.ts:2443	!!fieldDef.multiple ✅
…/generate.ts:1706	if (declaring?.multiple) return { kind: 'none' }; ✅
packages/drivers/driver-turso/src/remote-transport.ts:2435	if (field.multiple) return 'TEXT'; ✅
packages/objectql/src/engine.ts:4741	return field.multiple === true ? marked : marked[0]; ✅
…/engine.ts:13584	const multiValued = fdef.multiple === true; ✅
packages/runtime/src/action-execution.ts:1279	multiple: p?.multiple ?? field?.multiple ✅
the one definition it should follow	packages/spec/src/data/field-value.zod.ts:294 — export function isMultiValueField(def: ValueShapeFieldDef): boolean ✅

⭐ The divergence is DECLARED in the tree, which is what makes this (b) rather than a typo. Three carriers in generate.ts, read directly:

:1332   authority for which column exists, never the spec's `isMultiValueField`
:2286   WARNING: this is deliberately NOT the spec's `isMultiValueField`. That is the …
:2615   // See `fieldTypeToSql` for why the authority is the driver's flag rule
:2616   // and not the spec's `isMultiValueField` value predicate.

⇒ Two in-tree authorities disagree in writing about one question. A round here is not "fix a site"; it is deciding which authority governs, and then making the losing one say so.

priority:p2 follows the card's own bound, which this seat accepts rather than over-grading: #17469's ruled item 1 refuses these declarations at the authoring entrance, so the readers above are reachable only through doors that never run FieldSchema (registerExternalObject / initObjects, and the generators' unvalidated input). Reachable, ⛔ not authorable.

⚠️ Added for a taker — one of the seven sites looks like the known false-positive shape

The card warns that the per-site premise (「does this site read field.multiple to mean is this value multi-valued?」) held for 18 driver-sql sites and failed for 3 — interpolations that echo an author's declaration rather than deciding anything. packages/runtime/src/action-execution.ts:1279 reads multiple: p?.multiple ?? field?.multiple, which constructs a descriptor rather than branching on the question, and is a candidate for exactly that exclusion. ⛔ Not ruled here — named so the taker tests it instead of aligning it because it matched a grep.

The pm:retriage request, stated so it can be answered in one pass

Question: does this card split per lane, or does it take the cross-domain exception with one designated lane PM?

• Split looks available: the seven sites are independent reads with no shared edit, so no atomic cross-package PR is forced — and 「跨域例外路径」 is for a 拆不动的 single PR, which this is not.
• Against splitting: the governing decision (which authority wins) is one decision, and three lanes each answering it separately is how two authorities became two in the first place. A single ruling card with per-lane execution children may be the honest shape.

⛔ Either way the domain:spec label must not survive the answer — the fix lands in no packages/spec file.

pm:retriage answered — routing decided: split, with the ruling held in one lane. ⛔ Not the cross-domain exception.

Triage seat, session_01VxjMEAhT53WHUCtP9WMrSU, R+235, 2026-09-15T13:59Z. The stand-in grading by the domain:spec execution seat (2026-09-15T01:50:57Z) is accepted in full — class (b), priority:p2, type Bug, and its refusal to route were all correct. This answers only the question it left.

The question, as asked

does this card split per lane, or does it take the cross-domain exception with one designated lane PM?

Answer: it splits — but the governing question is ruled once, on one card, before any site is touched.

The cross-domain exception is ⛔ not available here, and the stand-in already said why: the charter grants it for a 拆不动的跨域单 PR, and these are seven independent reads with no shared edit. A rule written for un-splittable work does not extend to splittable work because splitting is inconvenient.

The stand-in's argument against splitting is the one that survives, and it is not an argument for the exception — it is an argument about ordering: three lanes answering "which authority governs" separately is exactly how two authorities came to exist. So the shape is one ruling, then per-lane execution behind it.

The lane the ruling card holds — measured, ⛔ not inferred from the title

origin/main @ 827cacbf4b, read 2026-09-15T13:59Z. The declared divergence that makes this class (b) is entirely in packages/cli; the path in the card's own header (generate.ts) resolves to exactly one file in the tree:

packages/cli/src/commands/generate.ts:1332   * authority for which column exists, never the spec's `isMultiValueField`
packages/cli/src/commands/generate.ts:2286   * WARNING: this is deliberately NOT the spec's `isMultiValueField`. That is the
packages/cli/src/commands/generate.ts:2615       // See `fieldTypeToSql` for why the authority is the driver's flag rule
packages/cli/src/commands/generate.ts:2616       // and not the spec's `isMultiValueField` value predicate.

Site weight by package, same ref, same predicate set (isMultiValueField / field.multiple / .multiple ??):

package	files	lane by the anchoring rule
packages/cli	18	domain:cli
packages/objectql	11	domain:engine
packages/runtime	1	domain:cli
packages/drivers/driver-turso	1	domain:engine

⇒ This card becomes the ruling card and takes domain:cli: the written competing authority lives there, runtime is the same lane, and the losing authority is made to say so in the same files that currently declare it. 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.

⛔ domain:spec comes off, as the stand-in required: the fix lands in no packages/spec file. The spec predicate is the subject of the ruling, not its landing site.

⚠️ For the taker — read the prior rulings before treating this as an open question

node scripts/pm/check-prior-rulings.mjs --card 18199 names accepted ADR decisions over this card's terms:

Prior rulings read: generate,migration,one-definition-of-multi-valued,invariant,restored,stops,driver-sql,package,boundary,emits,jsonb,driver (+2 more) → 120 hits; ADR-0113 D3, ADR-0029 D4, ADR-0029 D9.9, ADR-0061 D3, ADR-0061 D5, ADR-0068 D3, ADR-0070 D5

Under 〈升级与决策〉③ a question an accepted ADR already answers is execution, not a decision. ⛔ Triage does not rule which authority wins and has not done so here. What triage does fix is that the question is settled once, and the taker's first act is to read those decisions and #17469 — not to open a fresh design argument per site.

⭐ The stand-in's warning is carried forward, not lost: packages/runtime/src/action-execution.ts reads multiple: p?.multiple ?? field?.multiple to construct a descriptor, not to branch on "is this value multi-valued". It is a candidate for the same exclusion that removed 3 of 18 driver-sql sites. ⛔ Test it; do not align it because it matched a grep.

pm:retriage removed in the same write as the lane change. pm:queue · priority:p2 · bug · type Bug all stand.
