plugin-security / objectql: an on-behalf-of insert by a crossing platform operator that names no organization may be stamped outside the delegator's organization set (source reading only; measure reach first)

Filing gate ①, the security exception ("may alter data": measure reach first). The source is a source reading by the isolated contract reviewer of PR #25048 (#24822 half 1), note N3 in 6309495055. It is not measured. Filed by domain:services seat 2 (seat post #21118, os-support-ai, session session_01UmqzD97e14iws6hmVhgZ5y). ⛔ Not a claim. ⛔ Ungraded and unrouted: the grade and lane are triage's.

Disclosure: the maintainer's ruling recorded on #9387 (5323310017) applies. This card states where the reading lives and the governing text. ⛔ No probe, request or payload goes on this card, its PR or any comment.

Reader (who acts): triage grades the card. The lane that takes it measures reach FIRST, and fixes only if reach is shown.

Where it lives (`origin/main` `72518d20f`)

The wall: packages/plugins/plugin-security/src/security-plugin.ts, the Layer 0 write wall (step 3.7) and its insert stored-image seam, for an on-behalf-of context (ADR-0090 D10) whose caller crosses the wall.
The stamp: packages/objectql/src/engine.ts, resolveSystemInsertOrganization, and the driver's injectTenantOnInsert. They fill an absent organization from the context's tenantId after the seam has run.
The reading: under group, the organization stamped onto such a row may never be held to the delegator's organization set. The reviewer judged it "existing before PR fix(objectql,plugin-security): an insert's explicit organization_id the Layer 0 wall judges is stored as sent #25048, identical before and after".

Governing text

ADR-0090 D10: a delegated write is bounded by the delegator's scope.
ADR-0105 D5: the engine stamps from the active organization when the value is absent, and validates explicit values.
ADR-0123 D2: the insert arms for a row that names no organization.

Why p1: an on-behalf-of insert by a crossing platform operator that names no organization may be stamped outside the delegator's organization set (ADR-0131). It is a source reading only, so measure reach first.

Thread-read: 6311031595
Serial constraints cleared:

PR fix(objectql,plugin-security): an insert's explicit organization_id the Layer 0 wall judges is stored as sent #25048, where the reading was made, landed as 2b1382a5b3.
group posture: a member's insert whose organization_id names another organization of its membership set is silently stored in the active organization (the engine's read-only strip), where #21666 ruled an explicit value meets the wall and is never rewritten #24822 half 2 (this seat, in flight) edits step 3.7's UPDATE seam composition and the engine's update strips. So this card measures first, and edits step 3.7 only after that PR lands.
Every open PR's file list was read: feat(objectql): the ReadableIds leaf inside a composed read scope is composed too — the nested master chain (ADR-0139 D6 as amended) #25072, fix(plugin-security)!: an update of a controlled_by_parent detail also asks for edit access on the master its body names (ADR-0055 §3) #25066 and feat(driver-sql,driver-turso,driver-memory,objectql,cli,metadata-protocol): plain organization key part in new unique indexes; the differ reads COALESCE(tenant) as tenant on a certified database (18.x step 7b-1 + 7b-2) #24893 do not touch resolveSystemInsertOrganization or its call site.
Seat 1's controlled_by_parent family (plugin-security: the controlled_by_parent detail write gate may not ask the master-edit question on one more write shape, where ADR-0055 §3 requires it (reach not measured; detail withheld under the disclosure ruling) #25049, plugin-security: under one master-reference declaration, a write to a controlled_by_parent detail is not held to ADR-0055's master invariant on every write shape (reach measured; detail withheld under the disclosure ruling) #25068) works the master-edit chain, not step 3.7.

Widened in place for round 2 (option P), by the seat call 6312131621:

packages/plugins/plugin-security/src/security-plugin.ts: resolveOperationPrincipals (~:8937 at 4feccc268), the delegated-principal prologue only, beside the dangling-delegator refusal. ⛔ Not step 3.7's composition, and ⛔ not assertControlledByParentWrite (seat 1's plugin-security: one more write to a controlled_by_parent detail is decided without asking for edit access on every master it involves, where ADR-0055 §3 requires it (reach measured; detail withheld under the disclosure ruling) #25044 / plugin-security: the controlled_by_parent detail write gate may not ask the master-edit question on one more write shape, where ADR-0055 §3 requires it (reach not measured; detail withheld under the disclosure ruling) #25049 / plugin-security: under one master-reference declaration, a write to a controlled_by_parent detail is not held to ADR-0055's master invariant on every write shape (reach measured; detail withheld under the disclosure ruling) #25068 region).
The three pins the rule turns red, rewritten to in-set organizations: tenant-layer0-verdict-on-operation.test.ts (two cases) and objects/default-row-scope-declarations.test.ts (one persona). Any further red fixture is named in the report before it is rewritten.
A new real-stack pin file under plugin-security/src/.
One .changeset/25063-*.md.
objectql is no longer touched: the stamp is not changed.

Clause-② (round 2): no (narrowing) — a delegated operation whose live active organization the delegator's membership does not back is refused 403 on a walled posture, where it was accepted. It is a BREAKING minor, and owes a review at CONTRACT_REVIEW_TIER before the queue.
Serial constraints cleared (round 2): no open PR touches security-plugin.ts (every open PR's file list was read). #24822 half 2 (this seat) edits step 3.7 and the engine's update strips, not the prologue.

No reach is shown through a public door: the one producer of an on-behalf-of context in this tree cannot build the shape, so every cell that reached needed a hand-built in-process context. The mechanism the card reads is confirmed (R3): step 3.7's seam does not judge a row that names no organization, and the engine's write target plus the driver's insert stamp then fill it. The fix that closes both postures lies outside step 3.7 and outside this card's declared file surface, and it narrows every delegated operation of that shape, not only inserts. The in-surface engine option closes group only. So no code was written and no PR was opened: the seat picks the option and confirms the narrowing face.

⛔ Disclosure (#9387, 5323310017): this record states the rule and an abstract reach only.

Reach, abstractly: shown in process under both walled postures. No public door builds the shape.
The rule P enforces is already stated in two places:
- ADR-0090 D10: a delegated operation is bounded by the delegator's scope;
- resolveDelegatorContext's own assumption that the agent and its delegator are in the same organization.

Ruling: option P. At the delegated-principal prologue (resolveOperationPrincipals), refuse 403 PERMISSION_DENIED for every operation of a delegated context:

on a walled posture,
where a live active organization is set,
and the delegator's membership does not back that organization.

The check is vetOrganizationClaim, the one spelling of that rule. ⛔ No second copy, and no new error code. single and contexts with no active organization keep today's answers.

Why not the others:
- C+B needs two seams and waits on group posture: a member's insert whose organization_id names another organization of its membership set is silently stored in the active organization (the engine's read-only strip), where #21666 ruled an explicit value meets the wall and is never rewritten #24822 half 2's region, and under isolated it turns a refusal into a silent empty read.
- A closes group only, and adds a second fill rule beside the driver's.
- D leaves a published shape (ExecutionContext.onBehalfOf) declared but unenforced (ADR-0049).
The narrowing is confirmed: Clause-②: no (narrowing), a BREAKING minor for @objectstack/plugin-security under the amended 「甲」 ([PM seat] triage (objectstack-wide) — 🟢 Routine · session_01AavokzJ5DndAwitDXvKy4U · trig_01NcnCtMS2tH46nUg1a5TaMJ (hourly) · state = body + the round records newer than it #6015 6303865025).
- It reaches every operation of that shape, not only inserts, and only for contexts no door builds.
- It owes a review at CONTRACT_REVIEW_TIER before the queue.
- The changeset carries the migration sentence for in-process producers.
The three red pins: their fixtures build a delegated context in an organization the delegator does not belong to, which the rule now refuses. They are rewritten to in-set organizations, and each rewrite is named in the PR.
The grants-cache window (the dev's finding 1) is refused by the same check. This card carries it; no separate card.
ADR-0090 D10's text is governed. It needs no change: P implements it. The PR says so, and ⛔ the PR does not edit the ADR.

Four axes (中文):

实际业务需求: 现有唯一的委托生产者(/mcp)天然满足该前提,真实流量不受影响;受影响的只有进程内自建委托上下文、却把它放在被代理人所属组织之外的调用方。
项目长远合理性: 在同时看得到两个主体的唯一位置执行 ADR 已声明的不变量,复用唯一的规则拼写。
防 AI 写错: AI 写的委托生产者若把上下文放错组织,第一次操作就得到响亮的 403,⛔ 不会被静默落到错误组织。
创业阶段不扩散: 只加一处检查;无新门禁、新错误码或新接口面。

Next: the claim 6311248489 is widened in place to the prologue and the three pins' files, and round 2 builds P.
