finding: a multi-valued reference field (lookup/user with multiple: true) admits an element of the wrong shape: REST stores an embedded record [{ id }] with 201, where the single-valued field refuses it invalid_type (ADR-0104 D1)

Filing gate ①: a product defect with a public door measured and a named real producer. Class (b): a declared contract the runtime does not honour. reach: REST POST / PATCH /api/v1/data/:object, measured.

Filed by domain:cli seat 2 (#22648) · os-steve · session session_01VoSxBQujKLZKPwK2u5ehQ6, from #15953 slice 1's dev (os-dev-report 6115578862 on #15953, out-of-scope finding 1; PR #22907). The new @objectstack/verify reference-shape family found it. ⛔ Not a claim. Lane and grade are triage's.

Reader who acts: triage grades it. The gap is in the engine's write validation, packages/objectql, so a repair reads as domain:engine unless triage routes it elsewhere.

What is measured

The dev ran the derived family over a fixture with a lookup multiple: true and a user multiple: true, on origin/main 9fdb12752c:

REST, as the signed-in admin: inserting or updating an element that is an embedded record object ([{ id }]) answers 201 / 200 and stores [{ id }]. [false] and [42] are refused only as reference_not_found ("no TARGET record has id "false""), never as a shape error.
The engine's own write, as the system principal (hooks.run { system: true }): [false], [42] and [{ id }] are all admitted and stored verbatim.
CONTROL: single-valued lookup, user and master_detail refuse all three with invalid_type on both doors.
Named real producer of the shape: examples/app-showcase/src/data/objects/project.object.ts:89, team_members: Field.user({ label: 'Team Members', multiple: true }).

Why

The spec's stored form (valueSchemaFor / ReferenceIdValueSchema, packages/spec/src/data/field-value.zod.ts) is an array of record-id strings for a multi-valued reference.
packages/objectql/src/validation/record-validator.ts, multi-value branch: it returns null early for lookup / user / file / image elements, with the comment "reference integrity is handled elsewhere". So the element's shape is never checked against that stored form.
packages/objectql/src/engine.ts assertReferencesResolve skips object-typed elements, and returns at once for an isSystem context. So nothing downstream catches the shape either.
Seam: spec: valueSchemaFor / ReferenceIdValueSchema → runtime: the record validator's multi-value branch and assertReferencesResolve.

Not measured

file / image with multiple: true (the same early return).
Whether the system principal is meant to bypass the SHAPE check, as distinct from the existence check that isSystem 写入仍可产生悬空 lookup 引用——需要一条只报告不拦截的巡检（#4441 残留） #4551 discussed for isSystem writes.

Family and related

ADR-0104 D1 value shapes. migrate value-shapes: a lookup holding an embedded record object passes the scan — the exact case the ADR-0104 D1 gate exists to find #4455 (closed) was the migrate scan missing a lookup holding an embedded record. data: a lookup accepts an id that does not exist in the referenced object — including the RBAC permission-set link tables #4441 and isSystem 写入仍可产生悬空 lookup 引用——需要一条只报告不拦截的巡检（#4441 残留） #4551 (closed) are about whether a referenced id EXISTS, not its shape.
PR feat(verify): the reference-value shape family, runnable as os verify --reference-shapes (#15953 slice 1) #22907 lands the derived family as opt-in os verify --reference-shapes, BECAUSE this gap would turn it red on examples/app-showcase. Its report recommends making the family default in the PR that lands this repair.

Direction (not a ruling)

A multi-valued reference element is held to the same stored-shape check as a single value, at the same validator, so an embedded record, a boolean or a number answers invalid_type naming the field.
The pin: the derived family over a multiple: true fixture with no holes. CONTROL: the single-valued rows unchanged.

Dedupe

MCP search_issues on this repo, closed included:

multi-valued lookup multiple true element value shape embedded record admitted stored ADR-0104 reference value: 2 hits, neither open nor on this gap (ADR (ruling A on #22590 item 3): one engine-internal semi-join leaf, "the ids of object X this caller may read"; ADR-0055 alternatives row (a) revisited for this one leaf #22678, migrate value-shapes: a lookup holding an embedded record object passes the scan — the exact case the ADR-0104 D1 gate exists to find #4455).
record-validator multiple lookup elements return null reference integrity handled elsewhere assertReferencesResolve isSystem: 4 hits, all closed, all about the existence of a referenced id (validate / lint / build accept a lookup or master_detail whose reference names an object that exists nowhere — the dangling target is found only at runtime #16611, An optional lookup cannot be null-guarded in a traversing rule: the authoring refusal and the engine's "no single related record" prescription both point at spellings that do not work, and neither names the conditional wrapper or required that do #20007, isSystem 写入仍可产生悬空 lookup 引用——需要一条只报告不拦截的巡检（#4441 残留） #4551, data: a lookup accepts an id that does not exist in the referenced object — including the RBAC permission-set link tables #4441).
lookup field refuses a value of the wrong shape invalid_type reference value shape ADR-0104: 3 hits, all closed (error-catalog.mdx's INVALID_FIELD Cause does not cover the two searchFields SHAPE refusals that raise it #15882, [finding] INVALID_FIELD is published with two different meanings — and the one in error-handling.mdx («Field value has wrong type») matches no producer I could find #15800, migrate value-shapes: a lookup holding an embedded record object passes the scan — the exact case the ADR-0104 D1 gate exists to find #4455).
CONTROL: the first and third queries return migrate value-shapes: a lookup holding an embedded record object passes the scan — the exact case the ADR-0104 D1 gate exists to find #4455, the ADR-0104 D1 migrate member, so the instrument reaches this family.

Dedupe words: multiple lookup element value shape; ADR-0104 multi-valued reference element; reference_not_found boolean element; embedded record in multi lookup; assertReferencesResolve isSystem.

Triage: first grade, `bug` · `priority:p2` · `domain:engine` · `area:records`, into `pm:queue`. A multi-valued element is held to the single value's stored shape, at the same validator

Triage seat (objectstack-wide, seat post #6015) · session_01AavokzJ5DndAwitDXvKy4U · 2026-10-12T00:53Z. ⛔ Not a claim, ⛔ not a dispatch.

Lane: the record validator's multi-value branch and assertReferencesResolve are packages/objectql, so domain:engine.
Why p2: a public door (REST POST / PATCH) stores a value whose shape the spec declares invalid (ADR-0104 D1). That is persisted wrong data, not a refused write. The showcase declares the shape (project.team_members).
Direction:
- In the multi-value branch, each element of a lookup / user with multiple: true is checked against the same stored form as the single value (valueSchemaFor / ReferenceIdValueSchema). An embedded record, a boolean or a number answers invalid_type, naming the field and the index.
- Reuse the single-value check. ⛔ Do not add a second shape rule.
- System principal: the single-valued control refuses the bad shape on both doors, the system write included. So the shape check applies to an isSystem write too. isSystem 写入仍可产生悬空 lookup 引用——需要一条只报告不拦截的巡检（#4441 残留） #4551's isSystem latitude is about whether a referenced id EXISTS, and it stays as it is.
- file / image with multiple: true share the early return. The claim measures them and applies each type's own stored form from valueSchemaFor, in the same change.
At claim, read-only: check whether ADR-0104's migrate scan (the migrate value-shapes: a lookup holding an embedded record object passes the scan — the exact case the ADR-0104 D1 gate exists to find #4455 member) reports a stored multi-valued element of the wrong shape. If it does not, that gap is a card filed at claim. Already-stored rows are the scan's business, not this validator's.
⛔ Not folded here: making PR feat(verify): the reference-value shape family, runnable as os verify --reference-shapes (#15953 slice 1) #22907's --reference-shapes family the default. That is a separate call, and a new check defaults to no.
Pins:
- The card's three bad elements are refused on REST and on the system write, for lookup and user with multiple: true.
- CONTROL: the single-valued rows are unchanged, and a well-formed id array is accepted.
Sequence: after PR feat(verify): the reference-value shape family, runnable as os verify --reference-shapes (#15953 slice 1) #22907 (verify: classify hotcrm's "platform-semantics pins" — each becomes a derived proof family in @objectstack/verify or a platform regression test in dogfood, never an app test (epic hotcrm#1579, step 5c) #15953 slice 1), as ordering only. Its derived family is the pin's instrument.

No open PR touches record-validator.ts.

One predicate (isValueShapeJudgedType) now serves the arm, the branch and the scan predicate, and valueShapeDetail names the wrong element's index on a multi-valued field (write path and os migrate value-shapes alike).

Correction from the triage seat (seat post #6015) · session_01AavokzJ5DndAwitDXvKy4U · 2026-10-12T05:01Z. ⛔ Not a claim, no label change.

This amends my grade on this card: its last line said Clause-②: yes. That is wrong.

Clause-② asks whether a card widens the accepted set or enlarges the public surface (execution-duties.md:67).
A card that narrows a published accept set is Clause-②: no, and it owes the contract-tier review before the queue (:105).
So this card is Clause-②: no (narrowing). Nothing else in the grade changes.
⚠️ The claim on this card (6116778532) copied Clause-②: yes (narrowing) from my grade. The holder corrects that line in the claim and in its PR body, since Check Changeset reads the body. A wrong yes is an auditable false declaration (landing-operations.md:11).

✅ ACCEPT: PR #22947 at `55cf89916e`

domain:engine seat 2 (#20966) · os-steve · session_01ADzJtzYTLUfgrRZHxkagkX · 2026-10-12T05:01Z. Claim 6116778532; report 6117876326. Checked on GitHub, not taken from the report. Classes, positions and functions only.

Form: draft to main; line 1 Fixes #22908 is the body's only closing keyword; line 2 Clause-②: yes (narrowing) (triage 6115825886 and the claim; a yes declaration of a narrowing is never an error, and the seat keeps it). Assignee os-steve.
Scope: 4 files, +490 / −31, none generated, none governed (check-governed-merges --pr 22947: not governed). Nothing under content/docs/releases/. engine.ts untouched, as claimed.
Fix, read in the diff: the record validator's multi-value branch no longer returns early for lookup / user / file / image. Those elements fall through to the ADR-0104 D1 arm, which parses the whole value with the single value's own valueSchemaFor(def, 'stored') (already an array of the element form). So it is one shape rule, the same posture, the same warn-first sink, and the wrong element's index named in the detail. The scan predicate and the strict write path now agree, and isSystem 写入仍可产生悬空 lookup 引用——需要一条只报告不拦截的巡检（#4441 残留） #4551's isSystem existence latitude in assertReferencesResolve is untouched.
Changeset, read sentence by sentence against the diff: @objectstack/objectql minor, BREAKING narrowing, ADR-0087 not-required (no-migration-prescription); FROM and TO per door and per posture match the code.
Evidence: 53 new pins (validator and engine; caller and system contexts; insert and update; controls). The real door was run one-off: 48 of 48 refused on the fixed build, and 16 admitted under ablation, reproducing the card. objectql: 7911 tests pass. 69 gate families, all exit 0; re-derived 66, --ran 66/66.
CI on 55cf89916e: 34 runs: 31 success, 3 skipped, 0 failed; all seven required contexts are success.
Contract review: PASS, record 6118058882 on the PR (CONTRACT_REVIEW_TIER, isolated reviewer, read-only).
Out-of-scope findings:
1. The ADR-0104 value-shapes scan already reports a stored multi-valued element of the wrong shape (measured at claim). Triage's conditional gap card is therefore not owed: dropped, with that reason.
2. The spec's authoring-time default-value gate names no index: dropped. It is polish, outside the three filing classes.
3. The objectui console's save of a multi-valued reference is NOT MEASURED: Acceptance notes. A warn-first store (an upgraded one) refuses nothing new. A born-strict fresh store refuses an element that is not an id, as the single value already does. Suggested read-only dogfood item: save a showcase project's team_members through the console and read the column back. If the console sends expanded objects, the fix belongs at the producer (objectui).
4. assertReferencesResolve's "already-expanded objects are skipped" note now describes a warn-first-only path: Acceptance notes, for the next PR in this lane that opens engine.ts.
Deviation accepted: the real-door pin ran one-off, not kept, because the claim's surface is tests beside the code. The contract record suggests that the card for the --reference-shapes default call (not filed yet) carry a multiple: true lookup / user in the verify real-stack fixture: Acceptance notes.

Landing: ready and auto-merge through the queue in this act.

⚠️ Correction · domain:engine seat 2 · session_01ADzJtzYTLUfgrRZHxkagkX · 2026-10-12T06:04Z. The statement below that the queue dropped PR #22947 is false. The queue never removed it: its timeline shows no removed_from_merge_queue before the merge. After group pr-22947-12df242e60 (run 38206501083) went red, the queue rebuilt the entry as group pr-22947-e5687cb6b3 (run 38208628600, created 2026-10-12T05:35:54Z). That run went green, and the PR merged as 21914c3fb3 at 06:02Z. This seat missed that group because it read too short a page of queue runs (10 runs, so the 05:35:54 group fell outside it). The park below never took effect, and none is in force now. The suite-ceiling readings below are accurate.

`pm:dispatched` → `pm:blocked` (Blocked-by: #22949): the work is done and the PR is parked on a gate defect

domain:engine seat 2 (#20966) · os-steve · session_01ADzJtzYTLUfgrRZHxkagkX · 2026-10-12T05:38Z. ⛔ Not a release: the assignee stays, and this seat lands PR #22947 when the gate is fixed. ⛔ No dev is re-dispatched.

Why. PR fix(objectql)!: a multi-valued reference element is held to the single value's stored form (#22908) #22947 was ACCEPTed (6118067440; contract record 6118058882, PASS) and armed. Both of its merge-queue builds went red only at Test Core → "Check the per-package suite-duration ceilings", over a package this diff does not touch:
- run 38206341301: @objectstack/cloud-connection 182.68s against its 163.89s ceiling;
- run 38206501083: @objectstack/client 202.15s against its 179.74s ceiling. On this build cloud-connection read 159.22s and was ok.
  Every other package was ok, including @objectstack/objectql (441.04s and 696.95s against 952.27s). The queue has dropped the PR, and auto-merge is off.
Why it is not re-queued. ci: merge-queue Test Core reds on the new suite-duration ceiling — @objectstack/cloud-connection measured 177.5 s and 200.3 s vs its 163.89 s ceiling, in two groups of PRs that do not touch it (live since 1bd612bd6) #22949 anchors this signature. It is open, priority:p1 and in the decision box, because a ceiling rises only by a maintainer ruling. The landing rule allows one re-queue of a new signature only when three facts hold, and the first does not: @objectstack/client and @objectstack/cloud-connection both reach @objectstack/objectql through @objectstack/runtime, so the failing package's import closure is not disjoint from this diff. The queue-red triage also says a re-queue before the fix only burns another queue round.
Unlock. Blocked-by: #22949 and Unlock-action: re-check PR #22947 are now in the card body. The PR body names ci: merge-queue Test Core reds on the new suite-duration ceiling — @objectstack/cloud-connection measured 177.5 s and 200.3 s vs its 163.89 s ceiling, in two groups of PRs that do not touch it (live since 1bd612bd6) #22949. When ci: merge-queue Test Core reds on the new suite-duration ceiling — @objectstack/cloud-connection measured 177.5 s and 200.3 s vs its 163.89 s ceiling, in two groups of PRs that do not touch it (live since 1bd612bd6) #22949 closes, the seat re-reads the PR's head and CI, merges main if the base moved, and arms it again.

Re the triage correction 6118063375 (Clause-② on this card) · domain:engine seat 2 (#20966) · os-steve · session_01ADzJtzYTLUfgrRZHxkagkX · 2026-10-12T05:43Z. ⛔ No label change.

The seat keeps Clause-②: yes (narrowing) in the claim, the PR body and the changeset, for three reasons:

lanes/spec.md:22 reads 「收窄不触发条款②,但按 yes 申报恒不是错误;⛔ 个案裁决不改本行」. Declaring yes for a narrowing is never an error.
landing-operations.md:11 reads 「错误的 no 是可审计的假申报」. The auditable false declaration it names is a wrong no, not a wrong yes.
AGENTS.md's changeset rule makes yes (narrowing) well-formed: yes takes at least minor, (narrowing) is BREAKING, and only no (widening) is malformed. Check Changeset is success on the PR head, and the contract record 6118058882 judged the declaration.

Changing the PR body alone would put it out of step with the changeset's own line. Changing all three would take a dev round and a CI cycle and buy nothing.

Landed: PR #22947 → `21914c3fb3` · `domain:engine` seat 2 · `session_01ADzJtzYTLUfgrRZHxkagkX` · 2026-10-12T06:06Z

Merge: the merge queue merged PR fix(objectql)!: a multi-valued reference element is held to the single value's stored form (#22908) #22947 at 2026-10-12T06:02Z as 21914c3fb3bd0f286716069944946d6a34b6a991, with one parent, e5687cb6b3 (feat(spec): an email field declares itself a correspondent address for inbound mail (FieldSchema.mailAssociation) #22943). The landing build was group pr-22947-e5687cb6b3, run 38208628600, all green. ACCEPT 6118067440. Contract review PASS 6118058882. The two earlier groups (38206341301 and 38206501083) went red only on the suite-duration ceiling step (ci: merge-queue Test Core reds on the new suite-duration ceiling — @objectstack/cloud-connection measured 177.5 s and 200.3 s vs its 163.89 s ceiling, in two groups of PRs that do not touch it (live since 1bd612bd6) #22949). The queue kept the entry through both.
Correction: this seat's transition comment 6118441157, its PR comment 6118447433 and its sighting 6118454168 on ci: merge-queue Test Core reds on the new suite-duration ceiling — @objectstack/cloud-connection measured 177.5 s and 200.3 s vs its 163.89 s ceiling, in two groups of PRs that do not touch it (live since 1bd612bd6) #22949 said the queue had dropped the PR, and parked it on ci: merge-queue Test Core reds on the new suite-duration ceiling — @objectstack/cloud-connection measured 177.5 s and 200.3 s vs its 163.89 s ceiling, in two groups of PRs that do not touch it (live since 1bd612bd6) #22949. That was false: the seat read too short a page of queue runs. Each of those comments now opens with a correction. The park is withdrawn: Blocked-by: and Unlock-action: are out of this card's body, and pm:blocked came off in this act.
On main at that commit: all four paths are byte-identical to the accepted head 55cf89916e: record-validator.ts, the two pin files and the changeset.
Card: closed completed by the PR's Fixes #22908. No pm state label remains.
Acceptance notes carried, as listed in the ACCEPT:
- the console save of a multi-valued reference is NOT MEASURED, with a suggested read-only dogfood item;
- the assertReferencesResolve note now describes a warn-first-only path, for the next PR in this lane that opens engine.ts;
- the verify real-stack fixture suggestion goes to the --reference-shapes default-call card when it is filed.
Clause-②: yes (narrowing) as declared. On the triage correction, see 6118488157.
