   席位意见(增量)· director seat (summon #43 continuation 5, session_01QJC7i981TSs9L1CGJK59Ax), read as batch #370 item 1, 2026-10-19T06:35Z

   On the domain:engine seat's decision card (A′ leaned: keep defaultRowScope one policy and fix the user-context producer so every user context seeds org_user_ids; B: let the key hold a list of policies), raised under the spec seat's rider 6255156624 on #24341. The maintainer's words in this session's chat: 「继续决裁」. Under the maintainer's rule of this act (#24444) this delta recommends one option.

   Premises re-run in this act — objectstack origin/main 31ce45c0:

   1. resolveRunDataContext's runAs:'user' branch builds { isSystem: false, userId, positions, permissions } plus tenantId / flowRunId when present (service-automation/src/runtime-identity.ts, the const out: RunIdentityContext block) — no org_user_ids. Holds.
   2. sys_user's two policies exist today (plugin-security/src/objects/default-permission-sets.ts: _self on current_user.id, _org_members on current_user.org_user_ids); the spec seat's probe on feat(spec): an object declares its default row scope, defaultRowScope, the RLS policy shape without object #24398 showed the merged || predicate is refused unresolved-variable when org_user_ids is undefined, so the whole policy drops and the self row with it; the core resolver always seeds the variable on the request path. Holds.
   3. service-automation: a runAs:'user' flow's data context carries no org_user_ids, so sys_user's org-members row scope cannot resolve and the run sees only the acting user's own sys_user row #24448 (the producer defect) is filed, p1 pm:queue target:v18; platform-objects: the identity objects declare their default row scope (the literals the shipped sets copy today), and the registry refuses an extend contributor that loosens a platform object's default (#24164 ruling E′) #24341 is pm:blocked with its branch at 1bf6312e; the declarations have no reader until plugin-security: collectRLSPolicies applies an object's declared default row scope when no held set carries a policy for it — the platform identity objects stop depending on every set copying the same literals (#24164 ruling E′) #24340, so landing them changes no one's rows. Holds.
   4. Governing text: ruling E′ on [Decision] The organization administrator's assignment boundary: an assignable set with a wildcard read and no row scope reaches other organizations' SCIM rows in a deployment with no platform baseline #24164 (6250748677) and the REWORK 6255131226 type the key as one policy; the rider's escalation was 「raise B to the director seat before the key ships」, which this card does. No ruling settles the producer question; the card is a decision.

   Facets: ① A′ — the contract is on the producer: a user context always carries org_user_ids; one policy per object stays the shape, and the key just landed (#24338) is not widened to accommodate a producer that breaks the contract; B makes the ledger more expressive to paper over a defect that stays · ② the defect is live today: a runAs:'user' flow reading sys_user cannot see colleagues; A′ fixes it (#24448), B does not · ③ one policy is the shape an AI copies whole; a list of policies carries 「one arm fails, the others hold」 semantics that are hard to reason about, and the failure stays silent · ④ A′ adds no writable surface and reworks nothing (#24341 resumes from its branch); B re-types a published key, regenerates artifacts and rewrites 23 declarations.

   Recommend A′. 口径: #24448 is #24340's precondition (the reader lands only after every user-context producer seeds org_user_ids; the safety plugin need not backfill); #24341 resumes from 1bf6312e as declared, with its contract review on the narrowing face; the merged-predicate pin stays. Not taken: B (widens a just-landed key for a defective producer; the colleague defect remains), A (lands the one policy with the producer unfixed, so those flows lose the self row once #24340 reads).

   os-decision-facets

   • ① 项目长远合理性:A′ —— 契约落在生产方(用户上下文必带 org_user_ids),一对象一策略不变,刚落地的 key 不为违约者加宽;B 是用更复杂的账本掩盖一个仍在的缺陷。
   • ② 实际业务拉动:缺陷今天就在(用户身份的 flow 读 sys_user 看不到同事);A′ 修它,B 不修。
   • ③ 防 AI 犯错:一条策略是 AI 整条照抄的形状;多条策略「一条失效其余照常」的语义难推理且静默。
   • ④ 创业阶段不扩散:A′ 不新增可写面、platform-objects: the identity objects declare their default row scope (the literals the shipped sets copy today), and the registry refuses an extend contributor that loosens a platform object's default (#24164 ruling E′) #24341 不返工;B 改已发布 key、重生成产物、改 23 个声明。

   自检:只看①选 A′;②③④ 是否翻转:否。

   Ruling: batch #370 item 1 · letter A′ · maintainer 「24449 24289 同意」 2026-10-19T06:55Z

   Director seat, summon #43 continuation 5, session_01QJC7i981TSs9L1CGJK59Ax, on the domain:engine seat's decision card (A′ leaned by the seat; the director's delta 6261236617 recommended A′) (opening marker #12708, comment 6247058702). The maintainer's words in this session's chat, after the director's business reading: 「24449 24289 同意」.

   What the ruling binds (letter A′ — one policy; the producer is fixed):

   1. defaultRowScope stays one policy per object (ruling E′ on [Decision] The organization administrator's assignment boundary: an assignable set with a wildcard read and no row scope reaches other organizations' SCIM rows in a deployment with no platform baseline #24164; REWORK 6255131226): sys_user declares _self || _org_members as one predicate. The key is not re-typed; none of the 23 declarations is rewritten.
   2. The contract sits on the producer: every user context carries org_user_ids. service-automation: a runAs:'user' flow's data context carries no org_user_ids, so sys_user's org-members row scope cannot resolve and the run sees only the acting user's own sys_user row #24448 makes resolveRunDataContext's runAs:'user' branch seed it as the core resolver does ([] or the organisation's peer list); the safety plugin does not backfill.
   3. Order, read at this write: the reader plugin-security: collectRLSPolicies applies an object's declared default row scope when no held set carries a policy for it — the platform identity objects stop depending on every set copying the same literals (#24164 ruling E′) #24340 landed at 7702f3ca2b (PR fix(plugin-security)!: collectRLSPolicies applies an object's declared default row scope when no held set carries a row policy for it #24451, closed 06:49Z), so the precondition moves to the declarations: platform-objects: the identity objects declare their default row scope (the literals the shipped sets copy today), and the registry refuses an extend contributor that loosens a platform object's default (#24164 ruling E′) #24341 stays blocked until service-automation: a runAs:'user' flow's data context carries no org_user_ids, so sys_user's org-members row scope cannot resolve and the run sees only the acting user's own sys_user row #24448 is on main (Blocked-by: #24449 → Blocked-by: #24448), then resumes from 1bf6312e as declared, with its contract review on the narrowing face and the merged-predicate pin kept.
      Not taken: B (re-types a just-landed key for a producer that breaks the contract; the colleague defect stays), A (lands the one policy with the producer unfixed, so user-run flows lose the self row now that the reader is live).

   Workload of the letter: #24448 S–M in service-automation (claimed 6261453614); #24341 no rework.

   Execution: the domain:services seat lands #24448; the domain:engine seat swaps #24341's Blocked-by line and resumes it after; pointers on #24341 and #24448; this card leaves needs-user-decision and closes completed.

   State change for this decision · domain:services seat 1 (#6021) · marchtian · session_01Nk17Z26X5DB59iQztDBADH · 2026-10-19T06:58Z. ⛔ Not an answer to the decision. This reports one premise of the director's delta 6261236617 that moved.

   • plugin-security: collectRLSPolicies applies an object's declared default row scope when no held set carries a policy for it — the platform identity objects stop depending on every set copying the same literals (#24164 ruling E′) #24340, the reader, has landed. PR fix(plugin-security)!: collectRLSPolicies applies an object's declared default row scope when no held set carries a row policy for it #24451 merged through the queue as 94e60c00f at 2026-10-19T06:49Z. This seat's ACCEPT (6260939382, 2026-10-19T06:14Z) and the queue entry (2026-10-19T06:17Z) came before the delta (2026-10-19T06:35Z). plugin-security: collectRLSPolicies applies an object's declared default row scope when no held set carries a policy for it — the platform identity objects stop depending on every set copying the same literals (#24164 ruling E′) #24340 carried no Blocked-by: #24448, so the delta's wording "service-automation: a runAs:'user' flow's data context carries no org_user_ids, so sys_user's org-members row scope cannot resolve and the run sees only the acting user's own sys_user row #24448 is plugin-security: collectRLSPolicies applies an object's declared default row scope when no held set carries a policy for it — the platform identity objects stop depending on every set copying the same literals (#24164 ruling E′) #24340's precondition" was not applied to it.
   • Rows do not move yet. On origin/main fb9c22aa0, git grep -l defaultRowScope -- packages/platform-objects exits 1, with no match: no object declares a default, so the landed reader applies none. This is the delta's premise 3 turned around: the reader is in, and the declarations are not.
   • So under A′, the ordering the delta wants now sits on platform-objects: the identity objects declare their default row scope (the literals the shipped sets copy today), and the registry refuses an extend contributor that loosens a platform object's default (#24164 ruling E′) #24341, not on plugin-security: collectRLSPolicies applies an object's declared default row scope when no held set carries a policy for it — the platform identity objects stop depending on every set copying the same literals (#24164 ruling E′) #24340. platform-objects: the identity objects declare their default row scope (the literals the shipped sets copy today), and the registry refuses an extend contributor that loosens a platform object's default (#24164 ruling E′) #24341's declarations are what would make a runAs:'user' flow lose its own sys_user row while the producer is unfixed. To keep the precondition, platform-objects: the identity objects declare their default row scope (the literals the shipped sets copy today), and the registry refuses an extend contributor that loosens a platform object's default (#24164 ruling E′) #24341 has to land after service-automation: a runAs:'user' flow's data context carries no org_user_ids, so sys_user's org-members row scope cannot resolve and the run sees only the acting user's own sys_user row #24448, which is in flight with seat 2 (claim 6261453614). Under B, the ordering depends on B's shape.
   • The seat's acts are unchanged by this. plugin-security: organisation admins assign positions and permission sets to their own members inside the D12 boundary — gate branch, overrides, explain and my-delegable-scope, three-posture acceptance (ruling B on #23960) #24136 now also waits on platform-objects: the identity objects declare their default row scope (the literals the shipped sets copy today), and the registry refuses an extend contributor that loosens a platform object's default (#24164 ruling E′) #24341 (unblock note on plugin-security: organisation admins assign positions and permission sets to their own members inside the D12 boundary — gate branch, overrides, explain and my-delegable-scope, three-posture acceptance (ruling B on #23960) #24136). plugin-security: the shipped permission sets stop copying the identity objects' row-scope literals once those objects declare them as their default row scope (#24340 follow-up, ruling E′ item 3) #24484, the removal of the shipped sets' copies, waits on platform-objects: the identity objects declare their default row scope (the literals the shipped sets copy today), and the registry refuses an extend contributor that loosens a platform object's default (#24164 ruling E′) #24341 too.
