Step 1 composesplugin-security's real rules, so the claimant runs them, and adomain:servicesreviewer reads the configurations tried.- Why p2, measurement-first: a possible one-bit disclosure, seen only under a synthetic read scope. The resolver's docblock declares the elevation deliberate, on the premise that write access to a detail implies read access to its header. If no real configuration breaks that premise, there is nothing to fix. If one does, it is a disclosure in the security family. So the card stays in that family until Step 1 answers.
- Step 1 is the whole first dispatch. Measure only, no fix:

Clause-②: no - Narrowing: a detail write naming a header the caller cannot read answers what a write naming a header that exists nowhere answers. It owes one contract-review-tier review before the queue; the changeset carries the arm and its ADR-0087 disposition, as the family does (security(import): an import's reference resolution matches a lookup cell against a target whose exposure refuses reads (census row 7 of #22661) #22739, security(auth): the identity import hands
runImporta protocol withoutgetMetaItem, so its reference cells skip the target's exposure ask (census row 9 of #22661) #22800).

"summary": "This implements ruling A (6107211425). A master-detail detail write now reads its header in two steps, the same shape the preview uses. Step 1 is the caller's read door: the new ObjectQL.masterDetailHeadersCallerReads, one find under the caller's own context, projected to id (one id asked by equality, a batch by $in). Step 2 is the existing elevated, tenant-kept read, run only for the headers step 1 returned. A header step 1 does not return (hidden by row scope, a refused read, or a failed read) binds as a missing header: the reference check answers reference_not_found and parent-scoped requiredWhen/readonlyWhen meet an unbound parent. That is wired into resolveMasterDetailParent, resolveMasterDetailParents and, for master_detail fields only, assertReferencesResolve (via the new masterDetailHeaderExists). Those three seams cover every write path: insert (single and array), insertMany, update by id (repoint and previousParent included) and the predicate/bulk update. System callers ask no read door, the plain lookup probe is unchanged, and a readable header is still judged on its stored values. The 'settled upstream' docblock is rewritten to state the rule, and four comments that called the write's header read elevated-only are corrected. ADR-0055 is not edited and the preview's code is unchanged.",
"tests": "New file packages/objectql/src/engine-unreadable-master-detail-header.test.ts: 30 tests, all passing, synthetic read scope as in #22474. Refusal pins assert the ADR-0112 envelope (status 400, code VALIDATION_FAILED, field code) and that the message with the id removed equals the nonexistent-id message. Pins: (a) the reference check through insert, batch insert, repoint by id and bulk repoint, plus a refused read of the header object and the partial insertMany; (b) requiredWhen on insert, update by id and bulk, and repoint by id and bulk; (c) readonlyWhen by id and bulk, lenient and strict; the mechanism (read door first, then elevated). Controls: a readable header unchanged; a readable header with its state column hidden or masked still judged on the stored value; a nonexistent id; a controlled_by_parent detail unchanged under a readable header; a system caller unchanged with no read door asked; a plain lookup keeps its elevated probe. | Updated pins that encoded the old elevated-only read shape: engine-reference-tenant-scope.test.ts (3 pins: tenancy-disabled and group counts are now 2 finds; the ELEVATED pin now asserts door then elevated for each read, with the tenant on all 6) and engine-required-when-parent.test.ts (cost pin: one batched door read plus one batched elevated read per insert, and one door read per supplied header for the reference check). | Ablation, run from committed eefbde9 with node scripts/ablation-replace.mjs (trap-restored). The mutation forced masterDetailHeadersCallerReads to return every id: anchor x1 -> x0, blob 513539a2e224 -> 118559d7a44d. The subject is imported from src by relative path, so no build was involved. Mutated run: 22 failed / 81 passed over 4 files. All 18 unreadable pins and the mechanism pin turned red, as did the 3 tenant-scope read-shape pins and the cost pin. All 12 behaviour controls stayed green. Restore: blob after restore 513539a2e224 == HEAD, git diff HEAD empty. | Full runs at bb5d739 (os-verify-lock VERDICT command-exit 0): @objectstack/objectql vitest run --project local gave Test Files 401 passed (401), Tests 7840 passed (7840). @objectstack/plugin-security vitest run (it aliases @objectstack/objectql to src, so the real SecurityPlugin rules ran, including the controlled-by-parent suites) gave Test Files 196 passed (196), Tests 3973 passed / 45 skipped. | An earlier full objectql run at 01ed9ca had 47 failed in 7 files. In each, the test double's find did not understand $in. The fix, e0775cb, asks one id by equality. A re-run of those 7 files plus the 4 header files passed: 11 files / 200 tests. | Merged head fef9354, after merging origin/main 72b26ed, pnpm install --frozen-lockfile, and pnpm --workspace-concurrency=2 --filter '@objectstack/objectql...' build (VERDICT command-exit 0): pnpm --filter @objectstack/objectql typecheck passed (tsc --noEmit plus check:test-typecheck OK; the 3 edited or new test files are in the tsconfig.test.json program, confirmed with --listFilesOnly).

"class: b · reach: exception: security (possible data disclosure) · evidence: ruling A (6107211425) says a write of a master-detail detail whose header the caller cannot read answers exactly what a write naming a header that exists nowhere answers. That does not hold for an object that also declares a predicate rule traversing one hop through its master-detail FK. ObjectQL.resolvePredicateRelated (the #18682 related read, whose docblock records an 'accepted cost') reads a tenanted master elevated, with no read door, and its verdict comes before the reference check. A scratch probe on fef9354 with a synthetic read scope (not committed) found 3 different answers for the same write: a header that exists nowhere gave _record rule_violation; an unreadable open header gave _record rule_violation; an unreadable locked header gave invoice reference_not_found. So the answer for an unreadable header still depends on its stored state.

Landing held. The ruling's stated outcome was measured not to hold on one path, so this PR stays draft and un-armed as an objection window until the maintainer answers #22892. Under every option there it lands as is; on the answer this seat readies it and arms auto-merge.

Filing gate: ① under the possible-data-disclosure exception. The first step is to measure reachability. Measured by #22474's dev (os-dev-report 6085563448,
out_of_scope_findings[0]) with a synthetic read-scope middleware, not withplugin-security's real rules. Filed bydomain:engineseat 2 (seat post #20966),session_01Bw3y2DWhT9RPnrmDsNqEVG.⛔ Not a claim; triage grades and routes.Ruled A (6107211425): a detail write under a header the caller cannot read answers as a nonexistent header, every master-detail detail; Step 1 struck;domain:engineclaims the ruled fix.reach: exception — possible data disclosure, unmeasured at a real door. Step 1 is the measurement below. If it finds no reachable caller, this card closes as not planned with that evidence.
What was seen
resolveMasterDetailParent/resolveMasterDetailParents(packages/objectql/src/engine.ts) read underreferenceCheckContext(the caller's context plusisSystem). That is [finding] master-detail parent binding reads the header with no tenant —parent.*predicates leak another org's header fields; the dangling-reference audit is blind to cross-org references #19837's fix, which closed the cross-organization version of this oracle.requiredWhen: "parent.status == 'sent'"is evaluated against that header. With a read-scope middleware that hides headerhxfrom the caller while the caller may write a detail line under it, the insert admits whilehx.statusis draft. It refusesdescriptionasrequiredoncehx.statusis sent. So each write discloses one bit of a header the caller cannot read, and a caller who can author the rule chooses the comparison. The reference check also admitted the unreadable header id.controlled_by_parent(ADR-0055). The disclosure exists only if a real deployment lets a caller write a detail whose header that caller cannot read.validate()preview binds no master-detailparentheader in either mode, so an import dry run refuses a detail row whose rule readsparentwhile the write admits it #22474) makes the preview read the header through the caller's read door, keeping only values served in full. So for such a caller, the preview and the write can disagree, and PR fix(objectql): a validate() preview binds the master-detail header the write binds (#22474) #22518's changeset says so.Step 1 — measure reachability (owed before any fix)
On a real
ObjectQL+SecurityPlugin+SqlDriverstack, in each posture, find whether any configuration grants a caller write on a master-detail detail object while denying read on the header row. The configurations to try are object permissions, sharing rules,controlled_by_parent, and an RLS policy on the master. Try both insert and update. Also try the update-pathreadonlyWhenthat readsparent.Who acts on it
