approvals: the `team` approver expansion is not organization-screened either — a cross-org team resolves into a request's approver slate

[os-warren]

Found while verifying the warrant of #10153 ("every sibling approver expansion is org-scoped"). Filed separately rather than widened into that card, per its scope fence.

What was measured

#10153's body lists team among the org-scoped expansions:

• team → expandTeamUsers(value, directoryOrg)

That is not what main does. packages/plugins/plugin-approvals/src/approval-service.ts calls it with one argument at both call sites (the resolveApproverSpec branch and the expression / resolveAs branch), and the method takes no organization parameter at all:

private async expandTeamUsers(teamId: string): Promise<string[]> {
 ...
 rows = await this.engine.find('sys_team_member', {
 where: { team_id: teamId }, fields: ['user_id'], limit: 10000, context: SYSTEM_CTX,
 } as any);

team is also the only graph-shaped type not wrapped in the bounded(...) helper that applies filterApproversWhoCanRead on a cross-org slate — department, position and org_membership_level all are.

Measured on a fake-engine harness at 04096f17e, with a request in org_a routed to a team stamped organization_id: 'org_b':

[PROBE W] org_a request, org_b team -> pending_approvers = ["u_team_b"]

For contrast, on the same tree and the same run, the screened sibling resolves to the dead literal:

[PROBE B] org_a request, only an org_b `cfo` holder -> pending_approvers = ["position:cfo"]
[PROBE B2] same-org `cfo` holder present -> pending_approvers = ["u_pos_a"]

Why it is not obviously the same bug as #10153

sys_team carries an organization_id column (packages/platform-objects/src/identity/sys-team.object.ts), so a team_id transitively names exactly one organization — unlike sys_user.manager_id, which names a row in a global identity table with no tenancy fact on it. An author who picks a team has, in principle, already picked an organization.

What is unscreened is the case where the authored team value points at another organization's team: nothing re-verifies that the team belongs to the request's organization, so the slate silently crosses the boundary.

packages/spec/src/automation/approval.zod.ts also declares both types unscoped in the same table:

team: false,
manager: false,

That flag answers "does the ADR-0105 D9 organization: declaration apply to this type" (retargetability), which is not the same question as "is the expansion screened to the request's organization" — but it does mean the two unscreened branches sit together deliberately, and a fix for one should say what it implies for the other.

Related

• approvals: the manager approver resolves sys_user.manager_id with no organization screen, while every sibling approver expansion is org-scoped #10153 — the same question for the manager branch (its warrant is what this issue corrects)
• Design: does approver routing imply record read visibility? (#7345 model half) #7497 — Design: does approver routing imply record read visibility?

Filed unassigned for triage.

Triage: lands in packages/plugins/plugin-approvals/** (approver-expansion resolution), domain:services; rationale: this is the same org-screen family as #10153 (manager approver, dispatched) and #10119 (criteria sweep) — a team approver expansion resolving a cross-org team into a request's approver slate is a tenant-isolation defect against the same declared invariant every sibling expansion already honours. pm:queue + security, type Bug. Reproduction/named landing symbol is in the body; dispatch alongside (not before) #10153 so both org-screen fixes read the final approver-resolution shape — flag the same-file serial constraint in the claim.

Size/model suggestion: M, opus (security-boundary judgement, but a bounded org-screen add mirroring existing siblings).

PM 预判定级：Clause-②: yes（很可能） —— ⛔ 未认领，先把判据写在这里，免得被在错误层级上派出

本卡与 #10153（manager approver 未做组织屏）是同一形状，而 #10153 的执行位刚刚用测量把我给它的 Clause-②: no 推翻了（见 #10153 comment 5357409793）。推翻它的机制对本卡同样成立：

approval-service.ts:1588 把"只剩 type:value 字面量"的审批人名单判为空，而 onEmptyApprovers:'fail' 策略对空名单抛 NO_APPROVERS。
实测（#10153 的 PROBE C-a / C-b）：今天一个唯一审批人跨组织的节点在 'fail' 下正常开单；换成已被组织屏筛过的类型则抛错。

给 team 加组织屏会产生同样的"只剩字面量"名单 ⇒ 同样把这类输入从被接受变成被拒绝 ⇒ 契约 accept/reject 变更 ⇒ Clause-② yes，须在 CONTRACT_REVIEW_TIER 上派单。本车道当前没有 claude-fable-5。

⚠️ 这个判定是从兄弟卡的测量推来的，隔了一层，不是本卡自己的读数。 接手的执行位必须自己复现（team 版的 C-a / C-b 探针）：若测出 team 不落入同一机制，则本卡可降回 opus——⛔ 但要用读数说话，不是用相似性。

一并留给实现者的两条现成情报（来自 #10153 的测量，可直接站在上面）

1. team 与 manager 并不对称，拆开处理需要论证而不是假定：sys_team 带 organization_id，一个 team id 传递地指定了唯一一个组织；而 sys_user.manager_id 指向的全局身份表完全没有租户事实。所以 manager 是更锋利的洞，team 的屏可以直接用 team 自己的组织戳，不必走 sys_member 成员测试。
2. spec 自己的 APPROVER_ORG_SCOPED 把 team: false 与 manager: false 并列（packages/spec/src/automation/approval.zod.ts）。该表回答的是 ADR-0105 D9 的可重定向性而非屏蔽，所以它不否定加屏——但两者同处一个已声明的类，单独移走一个就是拆类，这件事要在 PR body 里论证。

⚠️ 另见 #10231：分诊在 #10153 上援引的"受治理的一侧"在本仓不存在（provablyDisjointOrgs / screenToTenant 零命中，带反向对照），且 TeamGraphService.managerOf(userId, _organizationId) 丢弃组织参数。⇒ 别把"framework 内已有一群筛过的同级"当成既定前提。

本卡保持 pm:queue、未认领。

• Branch: claude/issue-10230-team-approver-org-screen
• Worktree: ../objectstack-10230（per-repo；⛔ 不在共享主检出上编辑；⛔ 不用 git stash）
• File surface: packages/plugins/plugin-approvals/src/approval-service.ts + 同包测试。⛔ 零 packages/spec 所有权（车道红线）—— packages/spec/src/automation/approval.zod.ts 的 team: false 只读不改（见下）；⛔ 不碰 content/docs/releases/。
• Container & model: claude-opus-5（fable 用尽期间的授权层）
• Clause-②: yes —— 与 approvals: the manager approver resolves sys_user.manager_id with no organization screen, while every sibling approver expansion is org-scoped #10153 同族的 approver slate 组织收窄。今天已有一个跨组织 team 能进入审批人名单，修复后不能，这是对外可观测的接受集变化。
  ⇒ ⚠️ PR 保持 draft，落地后按流程挂 needs:contract-review 等分诊审查。⛔ 不自行翻 ready、不武装 auto-merge。
  ⚠️ 我明确不把它降级成 no：虽然标 yes 会让它排队等审，但「标 no 更省事」不是判据。若你在实现中发现它其实不改对外接受集，停下并说出理由，由 PM 重判。

⭐ 先例：#10334（卡 #10153）已于 01:55 合并，且已通过分诊契约审查

先读它的 diff 再动手 —— 它是同一个文件、同一类问题、已获批准的形状：

private async lookupManager(userId: string, organizationId?: string | null): Promise<string | null>

本卡是它的孪生半边。⚠️ 但不要假设两者可以照抄，卡面已经指出关键差异：sys_team 有 organization_id 列（sys-team.object.ts），而 sys_user.manager_id 指向的全局身份表没有租户事实。所以 team 这一侧的组织归属是可直接读到的，screen 的形状可能更简单也可能更严格 —— 自己测，别从 #10334 推断。

实现要求

1. 前提先复现：卡面给了探针（[PROBE W] org_a request, org_b team -> pending_approvers = ["u_team_b"]）。在同一棵树同一次运行里复现它，再改任何东西。
2. bounded(...) 的不对称是卡面的核心线索：team 是唯一没有被 bounded(...) 包、因而没有 filterApproversWhoCanRead 的 graph-shaped 类型，而 department / position / org_membership_level 都有。先量出这个不对称是否属实，再决定修复是「补 org 参数」还是「纳入 bounded(...)」—— 两者不等价，选哪个要给理由。
3. 二向 pin：跨组织 team 不再进入名单；同组织 team 仍然进入。只测前者，一个「把所有 team 都筛掉」的实现会全绿 —— 本车道今晚已在 finding: an org-stamped sharing rule's criteria sweep runs unscoped — recipients are org-aware, matched records are not, and per-org materialization (10103) multiplies it #10119 上被消融直接证明过这一点。
4. 对照 position 的既有行为：卡面记录 [PROBE B] 跨组织时解析成死字面量 "position:cfo"。如果你的 team 修复产生不同的失败形态（比如空名单 vs 死字面量），说明为什么这里该不一样，不要默认一致。
5. approval.zod.ts 的 team: false / manager: false：卡面明说那个标志回答的是 ADR-0105 D9 的可重定向性，不是「是否按请求组织筛选」。⛔ 不要去改它。但请在 PR 里说明本次修复对那张表意味着什么（卡面要求「a fix for one should say what it implies for the other」）。
6. 消融：预测签名先写下来再跑，双向，git hash-object 证明恢复逐字节一致。
7. 门禁并集在最终提交之后、干净工作树上跑；退出码在任何管道之前捕获；@objectstack/plugin-auth 的 TEST_DEBT 保持 109 不动。

⚠️ 一个不是你的 CI 红

Lint & Repo Gates 可能红在：

✗ check-query-options-erasure-ratchet
 • packages/spec/src/migrations/registry.ts:0:0 — Parsing error: Maximum call stack size exceeded

那是 #10449（P0，devx 车道 os-zhuang 已认领）：该门禁在进程内调用 ESLint，绕开了 pnpm lint CLI 上的 --stack-size=4000，红在 main 的测量群体上、与你的 diff 无关。⛔ 不为它改代码；重跑至多一次；仍红就在报告里指向 #10449，不要空转。
