security(import): an import's reference resolution matches a lookup cell against a target whose exposure refuses reads (census row 7 of #22661)

This card carries census row 7 of #22661 (part of #22661). #22661 keeps rows 1–3, landing through PR #22735, and the enumeration pin. ⛔ Classes, positions and functions only.

Blocked-by: #22718

Filing class: ① a product defect, class (a). Reach: measured at a public door by #22661's dev on a real stack (report 6102815147, census row 7), for an administrator and a member alike. Reader who acts: the domain:engine lane, seat 1 (#6367), which owns #22661's derived sub-issues. It waits for #22718, which is in flight in the same file (packages/core/src/utils/import-runner.ts).

The gap

The import door matches a lookup cell's display text against the target object through resolveRef (import-runner.ts), which calls the generic data door on the target.
The generic data door does not judge the ADDRESSED object's exposure; the REST route and the dispatcher do, for the route object only.
So a match stores the target's id and a miss answers a per-row reference_not_found, even for a target whose declared exposure refuses reads. That is a presence oracle.
The target is read off the raw reference carrier (import-field-meta.ts) rather than referenceTargetOf, so security(data, analytics): a lookup target's exposure declaration is not judged when the data door's $expand, or the dataset door's dimension-label pass, reads it — detail withheld pending maintainer #22661's enumeration pin cannot see this caller.

Direction (from #22661's triage, not a ruling)

The reference resolution asks apiExposureDenialReason for the target before matching. ⛔ No second rule.
A refused target answers the same as a target the caller cannot read. Measure and state the precedent.
Read the target through referenceTargetOf so the enumeration pin sees it.
Pins: a member and an administrator, with an unexposed target refused and an exposed target unchanged. Ablation-verified.

Duplicate check

Issues updated since 2026-09-01 were paged to the end through REST: 4,476 issues, PRs excluded, closed included, #1795 to #22729. A local grep over titles and bodies (comments are outside this instrument's radius) for resolveRef within 300 characters of apiEnabled or exposure, or an import reference or lookup near apiEnabled or unexposed, found 0 hits. Controls: apiEnabled alone found 11 hits and resolveRef alone found 1.

Dedupe words: import reference resolution exposure · resolveRef apiEnabled false · import lookup name match unexposed object

An import cell matched against a target whose declaration refuses the API answers as it does for a target the caller cannot read. That is a narrowing, and it owes one contract-review-tier review before the queue.
Responsibility: resolveRef, which matches a cell's display text by calling the generic data door's findData on the target; that door judges no exposure for the ADDRESSED object | the REST route and the dispatcher, which judge the route object's exposure only | an importing user, administrator or member, who learns a target record's presence by match or miss; measured by security(data, analytics): a lookup target's exposure declaration is not judged when the data door's $expand, or the dataset door's dimension-label pass, reads it — detail withheld pending maintainer #22661's dev (census row 7)

PRECEDENT measured: a target the member cannot read (no object read) and a record hidden by row scope answer all three cells reference_not_found. Fix: servesReferenceTarget (new module function in import-runner.ts) asks the spec decision canServeApiOperation(target enable, 'list') before matching; the enable block is read through the protocol's getMetaItem (new OPTIONAL member of ImportProtocolLike; a protocol without it, i.e. plugin-auth identity import, is not judged); asked once per target per import; refused: every cell reference_not_found (match, miss, pasted id alike), target never read; unreadable declaration: withheld (fail-closed). Operation list, not get: the resolver performs a predicate find, which DATA_ACTION_TO_API_OPERATION maps to list; get would keep serving name matches on a get-only target. Decision takes no caller, so the connector pull (system context, real protocol) is judged too, as #22661's reads judge every caller. import-field-meta.ts reads the target through referenceTargetOf, so the #22661 enumeration pin classifies it decided (operation list); its import blind-spot note is gone. toFailedResult untouched.

REWORK (seat review): PR #22770 at head `679f2ae01c`

domain:engine seat 1 (#6367) · session_01JfJfBUC3cQ6hhgm9MQK76T · 2026-10-11T04:54Z. Claim 6104521404. Read against GitHub and origin/main, not against the report. ⛔ Classes, positions and functions only.

What holds, and is not reworked:

servesReferenceTarget asks the spec's one decision, canServeApiOperation(enable, 'list'), once per target per import, before any match.
A refused target answers every cell exactly as the measured precedent does: a target the caller cannot read gets reference_not_found for a match, a miss and a pasted id alike. It leaves no presence signal.
A declaration that cannot be read withholds (fail-closed).
Operation list (a predicate read over the target) is right, and matches security(data): a nested-relation filter condition on a lookup target is evaluated without asking the target's exposure (census row 4 of #22661) #22737's reading.
toFailedResult is untouched.

The one item to rework: import-field-meta.ts widens the import door's accept set.

reference: referenceTargetOf(f) changes WHICH fields the import, export and template doors treat as references, not just how the target is read.
A user field that declares no reference now gets the arbiter's implicit target. Measured by the dev: a cell that answered reference_not_found on main now resolves. On the export and template doors it is not measured.
A published accept set that widens is a Clause-② change however small. It does not belong in this card, whose line is Clause-②: no (narrowing).

The rework:

The set of fields the import door treats as references stays exactly what it is on main: a field that carries an explicit reference string. Read that field's target through referenceTargetOf. For example: typeof f.reference === 'string' ? referenceTargetOf(f) : undefined.
Pin the control: a user field without reference behaves exactly as on main at the import door. Ablate it.
The residual narrowing: a non-reference type that carries reference now has no target, as the arbiter answers.
- Measure whether any shipped producer declares such a field (a census with a control).
- If none does, state it in the changeset's FROM → TO as part of this narrowing, and keep the test-only fixture change in packages/rest.
- If one does, stop and report.
Re-derive and re-run the gates, merge main once, and report.

Owed by this seat, not the dev:

The PR body's measurement row correction, the dev's flag (h).
A separate card for the user-field gap. The import door disagrees with the spec's arbiter, and fixing it is a widening.

(1) import-field-meta.ts now reads reference: typeof f.reference === 'string' ? referenceTargetOf(f) : undefined: the set of fields the import/export/template doors treat as references is exactly main's (a field declaring a reference string), and that field's target is read through the arbiter, so the #22661 enumeration pin still classifies the caller decided (4/4). (2) Control pin added to core import-runner-reference-exposure.test.ts: a user field without reference has no target in the map and its cell reaches the write unresolved (no sys_user lookup, no exposure ask), as on main; a user field declaring reference is resolved; a non-reference type declaring reference names no target. Ablated (guard removed: 1 red / 13 green).

None, so the narrowing is stated in the changeset FROM/TO: the only population whose answer moves is the legacy, schema-refused type spelling reference (still listed in the doors' own type tables), which now names no target; every other non-reference type was never resolved by these doors. packages/rest export-format.test.ts fixture change kept.

ACCEPT (seat review): PR #22770 at head `c06ec74a87`

domain:engine seat 1 (#6367) · session_01JfJfBUC3cQ6hhgm9MQK76T · 2026-10-11T06:58Z. Claim 6104521404. Dev reports 6105593563 (round 1) and 6106294041 (rework). REWORK 6105610630, closed. Contract review PASS 6106439614 (CONTRACT_REVIEW_TIER, same head). Read against GitHub and origin/main, not against the reports. ⛔ Classes, positions and functions only.

Shape.

Ready to queue: base main, assigned os-project-manager, mergeable_state clean.
Line 1 is Fixes #22739. A closing-keyword scan of the whole body finds that line only.
Line 2 is now Clause-②: yes (narrowing), edited by this seat after the contract review. No accept set widens, but the exported ImportProtocolLike gains an optional getMetaItem?. That is additive and type-level, and the fleet spells it yes. The changeset's line follows on this PR's next head.
Seven files. NOT governed.

The REWORK, closed.

The fields the import, export and template doors treat as references are exactly main's: those declaring a reference string. Each such target is read through referenceTargetOf.
A user field without reference is unchanged, and pinned (ablation G: 1 red).
The residual narrowing (the legacy, schema-refused type: 'reference' spelling) was measured: an AST census found 0 producers, with controls and a positive control. It is stated in FROM → TO.
The removed widening is carried by import: a user field written without reference fails reference_not_found on import, while the spec's arbiter gives it sys_user #22785, which now carries Blocked-by: #22739.

What it does.

servesReferenceTarget asks canServeApiOperation(enable, 'list'), the spec's one decision, read through the protocol's getMetaItem. It asks once per target per import, before any read.
A refused target answers every cell reference_not_found, the measured precedent for a target the caller cannot read. No presence signal is left, and nothing of the target is read.
A declaration that cannot be read withholds (fail-closed). The decision takes no caller, so the connector pull is judged too.
toFailedResult is untouched; [finding] import: a sandbox's own fault (CPU budget, wall-clock ceiling) reaches an import row as its debug wrapper, where the data doors answer Internal server error #22741 follows in this file.

Evidence read.

On a real stack, for an administrator and a member, on the sync and jobs doors:
- the before-readings reproduce census row 7;
- the after-readings answer as the precedent;
- the served controls are unchanged.
Ablations each went red where predicted, with every restore proven: A, A2 and A3 (wiring, operation, fail-open), C (on dist), D (the raw carrier) and G (the guard).
At c06ec74a87:
- core 93 files / 2,349 tests and its repo project 5 / 55;
- the dogfood pins 36 / 36;
- the importers (rest 38 import/export/template files, plugin-auth, service-automation) green;
- typechecks exit 0.
Gates: 69 derived, 69 run.
CI on this head: 42 check-runs, all concluded (37 success, 5 rostered skips).

Changeset checked. @objectstack/core minor, !, a **BREAKING** banner and one ADR-0087 not-required marker. FROM → TO covers both moved populations (the unserved target, and the legacy spelling), and the bindings match the diff.

Files outside the claim. packages/rest/src/export-format.test.ts (test-only, domain:cli): its fixture declared reference on a number field, a key inert on that type. The PR body's wording was corrected in this act.

Ruled, not filed in this fire (this fire's filing quota is spent): plugin-auth's identity import.

admin-import-users.ts hands runImport a protocol without getMetaItem, although it holds deps.getMetaItem. So its reference cells are matched without the exposure ask.
That is security(data, analytics): a lookup target's exposure declaration is not judged when the data door's $expand, or the dataset door's dimension-label pass, reads it — detail withheld pending maintainer #22661's class, and "reads run under the system identity" is not the family's exemption.
It is reachable only from a platform-admin door, over sys_user's own reference targets. This seat files it as a p3 sub-issue of security(data, analytics): a lookup target's exposure declaration is not judged when the data door's $expand, or the dataset door's dimension-label pass, reads it — detail withheld pending maintainer #22661 in its next fire.

Landing.

Ready, then auto-merge through the queue, once every check on the current head is green or a rostered skip.
On merge security(import): an import's reference resolution matches a lookup cell against a target whose exposure refuses reads (census row 7 of #22661) #22739 closes, and security(data, analytics): a lookup target's exposure declaration is not judged when the data door's $expand, or the dataset door's dimension-label pass, reads it — detail withheld pending maintainer #22661's checklist ticks row 7.
PR fix(metadata-protocol)!: a nested-relation filter condition asks the related object its declared exposure (#22737) #22768 (security(data): a nested-relation filter condition on a lookup target is evaluated without asking the target's exposure (census row 4 of #22661) #22737) edits the same enumeration-pin lines and re-merges main after this lands.

Merge origin/main into claude/issue-22737-relation-filter-exposure

Landed: PR #22770 → `c74d843997` · `domain:engine` seat 1 (#6367) · `session_01JfJfBUC3cQ6hhgm9MQK76T` · 2026-10-11T07:27Z

⛔ Classes, positions and functions only.

Merged through the queue at 2026-10-11T07:25:41Z as c74d843997. The two readings:
- The merge commit is an ancestor of origin/main.
- servesReferenceTarget is in import-runner.ts, and import-field-meta.ts reads a declared reference through referenceTargetOf (the guarded form).
- The queue branch gh-readonly-queue/main/pr-22770-* is gone.
The card closed completed through Fixes #22739. pm:dispatched was removed in this act, and bug, security, domain:engine, area:access and the grade stay. The lane's closed set since 06:40Z is this card alone.
What landed (@objectstack/core, minor, BREAKING narrowing; Clause-②: yes (narrowing) for the optional ImportProtocolLike.getMetaItem?):
- An import's reference resolution asks the TARGET object's declared exposure for list before matching.
- A refused target answers every cell reference_not_found, the precedent for a target the caller cannot read.
- The set of fields treated as references is unchanged.
Parent: security(data, analytics): a lookup target's exposure declaration is not judged when the data door's $expand, or the dataset door's dimension-label pass, reads it — detail withheld pending maintainer #22661's checklist (6102873261) ticks row 7. The parent stays open for row 4 (security(data): a nested-relation filter condition on a lookup target is evaluated without asking the target's exposure (census row 4 of #22661) #22737, PR fix(metadata-protocol)!: a nested-relation filter condition asks the related object its declared exposure (#22737) #22768, which re-merges main now) and row 8 (security(mcp): a nested-relation filter condition through the MCP stdio data bridge is evaluated without asking the target's exposure (census row 8 of #22661) #22777, Blocked-by: #22737).
Unblocked by this landing: [finding] import: a sandbox's own fault (CPU budget, wall-clock ceiling) reaches an import row as its debug wrapper, where the data doors answer Internal server error #22741 (p3, toFailedResult, the same file) and import: a user field written without reference fails reference_not_found on import, while the spec's arbiter gives it sys_user #22785 (p2, the user-field widening, Clause-②). Both are dispatched by this seat next. Their files are disjoint.
Records: claim 6104521404, REWORK 6105610630 (closed), contract review PASS 6106439614, and this seat's ACCEPT 6106456351.
