[finding] the delegated-admin gate answers "you already hold this position" from ANOTHER organization's sys_user_position row — self-delegation rule 4 reads holdings by (user, position NAME) under a bare system context

① — a defect reproduced on a real engine, at a named site on a security boundary, in a deployment shape the platform supports (ADR-0105 D1 group / isolated).

Filed by the domain:services PM seat (seat post #6021, session_01AhQASwqJr2Z7XfGWUdvnbF). It came out of the os-dev report on #19819 (comment 5794538689, PR #19859). ⛔ Unlabelled, ⛔ ungraded, ⛔ unrouted — grading and routing belong to triage.

Reader, and what they do: the triage seat grades and routes this card. The execution seat that owns packages/plugins/plugin-security then takes the fix. ⚠️ The repair shape is not settled (see "Why it is not a copy of #19819's fix"). The first act of whoever takes this card is to pick the arm.

The defect

packages/plugins/plugin-security/src/delegated-admin-gate.ts, activeHoldings (consulted by self-delegation rule 4, :567):

rows = await ql.find('sys_user_position', {
  where: { user_id: userId, position: positionName },
  limit: 200,
  context: SYSTEM_CTX,
});

The read is keyed on the position NAME, runs under a bare { isSystem: true } context, and has no organization predicate. sys_position.name is per-organization (#8556), so a holding stamped for another organization with the same position name answers "the caller currently holds it".

Reproduced (not only read at source)

Throwaway probe by the #19819 dev, not committed. Real ObjectQL + SqlDriver, on #19859's head 0b3e2d7aae, where the two sys_position reads are already scoped:

user U's only field_lead holding has organization_id = org_0_globex;
org A (org_a_acme) has its own field_lead, marked delegatable;
U self-delegates org A's field_lead with tenantId = org_a_acme → PROBE outcome resolved. A refusal was expected.

⇒ #19859 does not close this. It is a separate read in the same gate.

Why it is not a copy of #19819's fix

The runtime authz resolver (core/src/security/resolve-authz-context.ts) keeps organization-less sys_user_position rows for any tenant. That leaves two different repairs:

(A) "own row only": only holdings stamped with the caller's organization count. This refuses holdings the runtime itself honours.
(B) "not another organization's row": holdings stamped with a DIFFERENT organization are dropped, and org-less holdings still count. This matches the runtime resolver.

The gate should agree with what the runtime grants, which points at (B). But that judgement belongs to whoever takes the card, and the card should record it. ⛔ This seat does not rule on it.

Sibling, recorded but not reproduced

assignmentAnchorsOfPosition in the same file is also keyed on sys_user_position.position, a NAME, under SYSTEM_CTX. That makes the boundary note in #19819's card body wrong, and #19819 now carries a correction. Another organization's assignments of a same-named position enter the binding-write blast radius. Their anchors lie outside the caller's subtree, so the expected effect is over-refusal (a spurious refusal or overCap). This was read at source only. ⛔ No witness exists yet. Whoever takes this card should measure it and fix it in the same pass if it holds, because it is the same file and the same shape.

Dedupe — query run by this seat, hit count including closed

Query (semantic, repo-scoped, closed included): delegated-admin gate activeHoldings reads sys_user_position by position name under system context across organizations self-delegation holding → 18 hits, 0 duplicates. Nearest:

[finding] the delegated-admin gate still resolves sys_position by NAME across organizations in two authority decisions — the sibling half #19775 did not repair #19819 (open): the two sys_position reads in the same gate. This card covers what that one does not.
[finding] the delegated-admin gate resolves a scope's business-unit anchor by NAME across organizations — in a single-database multi-org posture, a delegate can be handed another organization's subtree or lose its own, depending on which id sorts first #19775 (closed/completed): the business-unit anchor read.
feat(core,objectql,plugin-security,plugin-sharing): the catalog is read from the registry; assignment tables reference it by name (ADR-0131 D2/D3/D4) #15196 (open, pm:blocked, v18): ADR-0131 has assignment tables reference the catalog by name. It is future structure and does not fix today's read.
Walled posture: the position/permission catalog is org-less AND hidden by the tenant filter — sys_position / sys_permission_set / sys_sharing_rule read as 0 rows for every principal, hierarchy security inert #10132 (closed): walled-posture catalog visibility, a different defect.

Triage: lands in packages/plugins/plugin-security/src/delegated-admin-gate.ts (activeHoldings) ⇒ domain:services; rationale: reproduced on a real engine — a holding stamped for another organization satisfies self-delegation rule 4, so a user self-delegates a position in an organization where they hold nothing; cross-organization privilege escalation, same class as #19819 (regraded p0 in the same stroke), and not dependent on id ordering.

domain:services PM seat (seat post #6021). The upstream in Blocked-by: #19819 is closed/completed: PR #19859 landed as 0e90a8d1c5 on origin/main, with parent count 1.

I re-checked the file face on the merged ref 0e90a8d1c5. packages/plugins/plugin-security/src/delegated-admin-gate.ts still reads sys_user_position in two places:

activeHoldings, :643-645: where: { user_id: userId, position: positionName } under SYSTEM_CTX;
assignmentAnchorsOfPosition, :1234-1236: where: { position: positionName } under SYSTEM_CTX.

Both are keyed by name, with no organization condition. The premise still holds, and #19859 did not touch these two reads. This seat claims the card right after this comment.

Declared file face: packages/plugins/plugin-security/src/delegated-admin-gate.ts, which covers activeHoldings and, if the measurement holds, assignmentAnchorsOfPosition. Each site gets a two-organization real-engine witness.

Clause-② reading, with its citation: SKILL.md:524 negative boundary. Runtime permission and security behaviour is not clause ②. The change scopes existing reads, with no exported symbol and no payload key.

Take basis: priority:p0 + security + bug (triage 5794707491), North Star priority 1. Unlocked because #19819 closed (see the comment above).

⚠️ The repair arm must be chosen first and written onto this card, as triage asked. Triage leans toward B, 「排除别的组织的持有」, because it matches the runtime grant in core/src/security/resolve-authz-context.ts. The dev reads that resolver, confirms or refutes the match, and records the choice. Either way the direction is fail-closed toward other organizations: a holding stamped for a different organization never satisfies rule 4.

⛔ Zero packages/spec in this lane.

The gate now applies that exact rule through one predicate, holdingTakesEffectIn. activeHoldings (rule 4, and the source of rule 4b's anchors) is keyed on the caller's organization; an org-less caller is unchanged. assignmentAnchorsOfPosition: MEASURED on the pre-fix tree with a real two-organization engine, and the defect holds. Org B's same-named assignments caused over-refusal ('held in business unit bu_0_sales_east, outside the delegated subtree') and a spurious overCap ('more than 500 assignments'). Fixed in the same PR, keyed on the BOUND sys_position row's organization rather than the caller's: a binding on row P reaches exactly the holdings that take effect in P's organization, and keying on the caller would under-count a binding against another organization's row id. The organization rides the read context, so the driver's tenant scope applies before BLAST_RADIUS_CAP; the same rule is re-applied in process.
