Merge pull request 'Port the IAM permission-management API from the abandoned iam-perm-ux branch' (#240) from fix/iam-perm-ux-port into main

Why: the port's authorization boundary, the build correction and the review
verdict must be recorded before delivery.

Evidence:
  /tmp/be-iam-perm-ux-impl-r1-20261021.json: pi, success (port)
  /tmp/be-iam-perm-ux-buildfix-r2-20261021.json: pi, success (build fix;
    r1 failed-unknown produced no record so nothing was imported)
  /tmp/be-iam-perm-ux-review-r1-20261021.json: pi, PASS, no blockers
  Host-side checks on the final head: gofmt -l clean; go build ./... and
  go vet on store/server/authz silent; go test on those packages green.

Impact: card metadata only.

+
+## 结果与验证（完成后填写）
+
+- 结果：仅修复三个测试文件的异步完成等待；门面卡等待 run.completed 持久事件，项目分页读到共享帧即结束，后台 idle 使用独立有界等待。生产代码、CI 与断言未修改。
+- 验证：worker red/green 对照与 focused count=10 通过；host 独立相关用例 count=3、go vet ./...、go test -count=1 ./... 通过（SELF）。完整原始收据由 Dev make evidence 捕获：/tmp/pr651-backend-host-full-20261020.json；源码对象 2ee469011e66b6bedcf6e9d87c8b1c026f7a8cef。当前最终 HEAD GATE 待运行，不以 SELF 放行。
+- 影响与剩余项：只影响测试等待；30s/20s 是基于磁盘实测及停顿注入的卡死上限，实际 CI 停顿时长仍不确定。AuthOwner 每帧持久写入的性能观察不在本次范围。旧 fail-stop 隔离现场保留。

+- 回收动作：<worktree remove、分支删除、prune；放弃路径注明原因>。
+
+## 恢复与重新定义单元（2026-10-20）
+
+- 用户在交接后明确“继续”；旧 run 290c8b13f4a4a9e5d67df066754ab3fd 已停止，不自动重试或接纳其诊断文件。
+- 现场已对账：唯一源文件差异为原隔离目录的 zz_diag_tmp_test.go；实际事件中仅有读源码、局部构建与本机测试/缓存操作，没有发现提交/推送、正式工作树修改或外部请求。原进程与现场写者已退出；隔离目录与本机诊断产物均保留。
+- 原执行器 allowed_paths 使用精确路径/目录前缀匹配，工作包的 ** 不起通配作用。新单元采用明确文件清单；诊断只能在这些现有测试中或仓外生成，禁止继续使用原会话。
+- 任务 worktree 已完整移至本卡登记位置，Git 与 development-manager 子模块路径已修复；没有删除文件。
+- Dev 启动 SELF 收据：/tmp/pr651-resume-20261020-a1.json（发现嵌套 worktree）、a2 至 a5（后续恢复检查，均未宣称通过）。原始完整文件在 /tmp。
+- 权威 Backend main 已由 API 核验并合入 c16495006dbf1cf6ee581b48d99bba1e7f9a377c；继承的 O2 改动仅为必需目标同步，不属本次修复。固定 Guidelines 与依赖已物化，配置与治理准入均通过。
+- 新单元目标：分别确认三项失败根因，在现有测试的精确路径内建立 red/green 证据；若确需修改生产逻辑，先形成能复现真实行为缺陷的失败测试。禁止弱化断言、仅拉长时间或不受控压力测试。
+
+## Review 与交付
+
+- 主协调者独立 Review：base c16495006dbf1cf6ee581b48d99bba1e7f9a377c，实现对象 2ee469011e66b6bedcf6e9d87c8b1c026f7a8cef；已核对真实完成事件的顺序、共享帧位于所有私有帧之后、等待仍有界、所有隐私与锚点断言保留；无阻塞发现。
+- 实施包与终态原始事件分开保存：/tmp/pr651-repair-unit-r2.json、/tmp/pr651-repair-r2.json、/tmp/agent-exec-1000/662a926e726431b930433273fc26f39a/raw-e8392e75611f.log；有效 completed 已在实际 result envelope 中核验。
+- 原始实验输出：/tmp/pr651-r2-red-anchor.txt、/tmp/pr651-r2-green-anchor-experiment.txt、/tmp/pr651-r2-stall-redgreen.txt。临时实验代码已撤除。
+- 交付：当前最终 HEAD 仍需自身 CI（ci/vet-and-test 与 governance），权威目标同步核验后经 PR 合入；GATE 与实际合入结果在源码外记录，不修改冻结候选。

+- 实施执行：agent-per-unit（配置：AGENT-EXECUTION.md；外部 Agent 一单元一新进程/会话/工作区）
+
+## 目标与非目标
+
+目标：Manager.ResolveHITL 先向 `hitlCh` 投递答案、再无条件 `UpdateRun(running)`，会在 runner 已把 run 写成 `completed/ended_at` 之后被覆盖回 `running/ended_at=NULL`，导致 run 永久卡在 running（无执行者）、会话永不释放、后续每次提交都是 409。修复为先以条件更新 `WHERE status='waiting_hitl'` 把 run 推进到 running（由 store 报告是否命中），再交答案给 runner；交答案后该 run 行此后唯一写者是 runner，不会被反向覆盖。
+
+非目标：不改 HTTP/server 层、不改其它 store 表的写入语义、不放宽任何断言、不引入新依赖、不改 schema。
+
+验收条件：(1) 新回归测试在修复前红（runner 抢先结算后 DB 仍为 `completed/ended_at`）、修复后绿；(2) `go test ./internal/runmgr ./internal/store` 全绿；(3) 独立 Review 无阻塞项。

+- 结果：七个权限管理入口（PatchRolePermissionsBatch、PreviewRolePermissions、AssignUserRolesBatch、PreviewUserRoleAssignments、ListRoleMembersForActor、ActiveRolesForUsers、CreateRoleCopyAndAssign）与配套类型（RoleBinding、PolicyReceipt、RoleAdminView、CapabilityAssociation、RoleAuthorityImport*、RoleCreate/RolePatch、RolePermissionChange/Conflict）全部移植到当前 main 的角色/权限模型上，8 文件 / +2184 行。移植首版并未编译通过（role_policy.go:2394 向 upsertRolePermissionsTx 传参错位：空 map 当 current、slice 当 after），已由独立 repair 单元按 main 的差量语义修正。
+- 验证：PASS——gofmt -l 干净；go build ./... 与 go vet ./internal/store/ ./internal/server/ ./internal/authz/... 均无输出（宿主独立执行）；go test -count=1 ./internal/store/ ./internal/server/ ./internal/authz/... 全绿（store 13.3s / server 29.5s / catalog ok）；独立 Review PASS、无阻塞项，逐 API 核对安全语义。
+- 影响与剩余项：只新增能力面，不改 schema（移植未引入新表），不改 Makefile/CI/子模块；未新增范围外功能。非阻塞遗留：Review 指出 PostgreSQL 下不同角色跨 batch 处理的潜在 lock-ordering 风险，以及若干测试缺口，两者已记入报告留作后续增量。

+## 审查结论：PASS
+
+本审查未发现阻塞项。七个移植 API 在语义层与 main 现有 role_policy.go / roles.go / account_search.go
+一致；安全语义保持 main 现有的 `system.permissions.*` / `system.roles.*` 授权门 + 账户作用域写入围栏
+（含 `requireSuperAdminTargetAccess` / `roleGrantsAccountAdministrationTx` / `requireRoleAuthorityWritableTx` /
+`policyWriteBatch` 等）；事务与一致性、审计与回执、与 #228/#234 的关系、测试质量均无证据证明存在
+继承能力丢失或静默行为改变。仅有一处非阻塞担心（PostgreSQL 下不同角色跨 batch 的
+潜在 lock-ordering 风险）与若干测试缺口，已列入"非阻塞建议"。

+## 2. 七个 API 与对应实现
+
+| # | 端点（routes，`server.go`） | handler（`server/roles.go` / `account_search.go`） | store（`store/role_policy.go`） | 授权闸 |
+|---|---|---|---|---|
+| 1 | `POST /api/admin/roles/permissions/preview` | `listRolePermissionPreview` | `PreviewRolePermissions` / `previewRolePermissionsTx` | `system.permissions.view` |
+| 2 | `POST /api/admin/roles/permissions/batch` | `batchPatchRolePermissions` | `PatchRolePermissionsBatch` / `patchRolePermissionsTx` / `upsertRolePermissionsTx` | `system.permissions.manage` |
+| 3 | `POST /api/admin/roles/copy-assign` | `copyAssignRole` | `CreateRoleCopyAndAssign` | `system.roles.manage`+`system.permissions.manage`+`system.roles.assign`（三同时） |
+| 4 | `GET /api/admin/roles/{roleId}/members` | `listRoleMembers` | `ListRoleMembersForActor` | `system.users.view`+`system.roles.view`（两同时） |
+| 5 | `POST /api/admin/users/role-assignments` | `assignUserRolesBatch` | `AssignUserRolesBatch` / `assignRolesTx` / `rebindUserRoleTx` / `checkRoleAssignmentTx` | `system.roles.assign` |
+| 6 | `POST /api/admin/users/role-assignments/preview` | `previewUserRoleAssignments` | `PreviewUserRoleAssignments` / `activeRoleTx` | `system.users.view`+`system.roles.view` |
+| 7 | `GET /api/admin/users/search`（追加 role 投影） | `searchAdminUsers`（修改） | `ActiveRolesForUsers` | `system.users.view`；role 字段附加条件 `system.roles.view`（`systemActionAllowed` 静默跳过） |
+
+类型承载面（`store/role_policy.go` 新增）：`RolePermissionPreviewInput`、`RolePermissionStateChange`、
+`RolePermissionConflict`、`RolePermissionPreview`、`RolePermissionPatchInput`、
+`RolePermissionBatchReceipt`、`RolePermissionBatch`、`UserRoleAssignmentInput`、
+`UserRoleAssignmentResult`、`UserRoleAssignmentBatch`、`UserRoleAssignmentPreview`、

+`rolePermissionChangeError`（带 `Unwrap()` 指向 `ErrInvalidRolePolicy`，与既有错误链兼容）。
+
+---
+
+## 3. 重点 1 —— 移植正确性（语义一致）
+
+主要结论：未发现语义丢失或静默改变；与 main 现有 role_policy.go / roles.go / account_search.go
+行为对齐。
+
+- `normalizePermissionChanges`（store/role_policy.go:1474-1504）：与 main 现有的
+  `ReplaceRolePermissions`（同文件 line 379）一样把"非 project.create"和"受保护动作"
+  在写入前拒绝；duplicate 拒绝；"Allowed=true && CapAllowed=false"非法组合拒绝。
+  对 `project.create` 之外的 audit 行保持原状（patch 语义），与
+  `TestRolePermissionsNormalizeLegacyRowsToProjectAccess`（main 既有的旧审计行单点投影测）
+  行为兼容。
+- `RolePermissionStateChange` 报告 `Before`/`After` 是按当前行 vs 合并后行计算的，并跳过
+  `ProjectAccessAction` 自身（`rolePermissionStateChanges` 把 expansion 跳过），所以预览
+  在关闭 project.create 时不会把 projection-row 误判为增删。
+- 关闭 project.create 后 `KeptLinkedActions` 仅列举"原本就显式有 row 的"linked 动作
+  （`keptLinkedRows`）；没有 row 的不会出现在 migration note 中，避免误导。
+- `CreateRoleCopyAndAssign` 选择 `current=nil` 作为新角色的 prior 状态（注释明确解释），
+  因为新角色行是在同一事务内插入的；这与原 feature 分支行为一致，避免在 helper 里
+  伪装既有行。
+- `AssignUserRolesBatch` 用与 `AssignUserRole` 同形态的 SQL
+  （`UPDATE user_role_bindings SET active=0 ... ; INSERT ... ; UPDATE users SET state_version=state_version+1 WHERE state_version=?`）
+  复用既有单用户路径所具备的乐观并发控制——`state_version` 重核确保 rebind 不覆盖并发变更。
+- `PolicyReceipt` 包含的 `ReceiptID` / `AuthorityEpoch` 直接读自 `PolicyReceipt` 结构
+  （已有），`RolePermissionBatchReceipt` 嵌入了该类型——回执格式与传统 `ReplaceRolePermissions`
+  完全对齐，没有改写 main 既有的回执 schema。
+- `RoleAdminView` 与既有的 `RoleAdmin`/`ListRoles` 投影共享 `RoleRecord + Permissions + ProjectAccess`
+  复合字段（`RoleCopyAssignResult.Role` 直接构造），不引入新读路径。
+
+未验证：原 feature 分支的代码已不在本仓（packet 注："唯一副本已备份"，且本工作区 detached HEAD
+无源分支 ref）。本评审只能与 main 现状 + diff 做对比，无法逐行比对其与原版的差异。这是结构性
+限制，已在"未验证"列出。
+
+---
+
+## 4. 重点 2 —— 安全语义（最高优先，逐 API 核对）
+
+| API | 入口授权 | store 内额外防御 | 是否绕过 main 既有 owner/admin 校验 / isAdmin 判定 / account-checked 写路径 |
+|---|---|---|---|
+| listRolePermissionPreview | `requireSystemAction("system.permissions.view")`（非 admin 路径同样拒绝） | `PreviewRolePermissions` 起手 `actor=="" → ErrAccountForbidden`；开 tx 后 `requireEnabledActorTx` 二次校验 actor 行；逐 item `previewRolePermissionsTx` 不写盘；没有走 `policyWrite`/`policyWriteBatch` | 否；纯读 |
+| batchPatchRolePermissions | `requireSystemAction("system.permissions.manage")` | `PatchRolePermissionsBatch` 走 `policyWriteBatch(actor, nil, …)` —— 即 `lockAccountUsers(actor)`，再 `requireRoleAuthorityWritableTx`，再 `replayReceipt`（同 key + 同 request_hash 才允许重放）；每 item 通过 `s.roleTx(item.RoleID, true)` 在 Postgres 上对 role row 加 `FOR UPDATE`；每个 item 走 `normalizePermissionChanges`（拒绝非 project.create / 受保护 / duplicate / 非法组合），`patchRolePermissionsTx` 内 `s.upsertRolePermissionsTx` 按 patch 语义 upsert，并对 `roles SET role_version=role_version+1 WHERE role_version=expected` 二次乐观并发 | 否；任何 `system.permissions.manage` 持有人都是该路径的合法写入者（与 `ReplaceRolePermissions` 对等，没有 target-side 校验，因为这是 system 层面的角色authority） |
+| assignUserRolesBatch | `requireSystemAction("system.roles.assign")` | `policyWriteBatch(actor, userIDs, …)` —— 同时锁 actor + 全部 target owner；`assignRolesTx` 内逐 item 调用 `requireSuperAdminTargetAccess(actorAccount, target)`（R5 抗 super-admin 篡改），非 super-admin 还检查 `roleGrantsAccountAdministrationTx(tx, item.RoleID)`（防止把 admin 角色批给用户形成提权路径，R4）；`checkRoleAssignmentTx` 校验 disabled / state_version / role enabled；`rebindUserRoleTx` 在 SQL 层再用 `state_version=? AND enabled=?` 重核；最后 `checkCapabilityAssociationTx`（project.create 联合关联门）；一笔失败全事务回滚 | 否；与单用户 `AssignUserRole` 同等保护，没有批量化造成的"开窗" |
+| previewUserRoleAssignments | `requireSystemAction("system.users.view")` + `system.roles.view`（双闸） | `PreviewUserRoleAssignments` 起手 `actor==""` 与 `validateRoleAssignmentItems`；开 tx 后 `requireEnabledActorTx` 二次校验 actor；逐 item 读 users 行并构造 preview，`account == nil` 通过 `roleAssignmentUserMissing` 区分；不写盘，不调 `policyWriteBatch` | 否；纯读；返回的字段范围与 `getUserRole` 视图对齐（owner/name/current role/状态匹配/错误原因） |
+| copyAssignRole | 三闸（`system.roles.manage`/`system.permissions.manage`/`system.roles.assign`） | `CreateRoleCopyAndAssign` 走 `policyWriteBatch(actor, userIDs, …)`；源 role `roleTx(..., true)` 行锁；`requireRoleAuthorityWritableTx`；按源 role 的 row 拷贝非受保护动作（`descriptor.Protected` 跳过），覆盖用 `normalizePermissionChanges`（同样拒绝非 project.create）；源 enabled project.create 但 merge 后 disabled 的情形被显式拒绝（`sourceWasCreator && !copyIsCreator → ErrInvalidRolePolicy`）；写后 `checkCapabilityAssociationTx`；最后通过 `assignRolesTx` —— 与 `assignUserRolesBatch` 完全相同的 anti-elevation + state-version 二次校验 | 否；copy 路径不会复制系统 grant（`copied` map 跳过 protected），不会复制 `IsSuperAdmin`/admin 身份（`CreateRole` 只插 roles 行），不会复制 project membership（不参与任何 project_* 表） |
+| listRoleMembers | `requireSystemAction("system.users.view")` + `system.roles.view`（双闸） | `ListRoleMembersForActor` 在 Postgres 走 `BeginTx(..., LevelRepeatableRead)`，SQLite 走普通 tx；起手 `lockAccountUsers(actor)`，对 actor 行 `FOR UPDATE`；然后 `requireSystemActionTx(tx, locked[actor], "system.users.view")` 与 `system.roles.view` 二次校验；`s.roleTx(roleID, false)` 校验 role 存在；SQL `SELECT ... FROM user_role_bindings b JOIN users u ON u.id=b.user_id WHERE b.role_id=? AND b.active=?`；附带 `account_directory_revision` 同一快照读 | 否；handler 层 cursor 用 `accountSearchKey` HMAC 绑定到 role/query/mode/status/private revision，不能跨 role/param 重放（`parseAdminCursor` `hmac.Equal` + version 比对） |
+| searchAdminUsers 的 role 投影 | 入口：既有 `system.users.view`（无变化） | 投影附加条件 `systemActionAllowed(actor, "system.roles.view")` —— 不开 reader 时静默跳过（无 role 字段），与既有的 read projection 模式一致 | 否；授权差异只在响应字段是否多一项 `role` 上，没有改变授权面。无 role 时一律为 `null`，无信息泄露 |
+
+关于越权路径的关键判断：
+
+- **检查 1：super-admin 保护**。`assignUserRolesBatch` 通过 `assignRolesTx` 强制 `requireSuperAdminTargetAccess`。
+  即便 actor 拿到 `system.roles.assign` 与 is_admin，把一个非自身的 super-admin 用户塞进
+  assignments 也立刻被拒绝。`copyAssignRole` 通过 `assignRolesTx` 走的是同一函数，复用同保护。
+- **检查 2：admin 角色 escalation**。`roleGrantsAccountAdministrationTx` 检查目标 role 是否
+  携带任何 `system.users.* / system.roles.* / system.permissions.*`，非 super-admin 一律拒绝。
+  与单用户 `AssignUserRole` 行为完全一致。无绕过。
+- **检查 3：account-checked 写路径**。三个写 API（`PatchRolePermissionsBatch` / `AssignUserRolesBatch` /
+  `CreateRoleCopyAndAssign`）通过 `policyWriteBatch` 借用 main 既有 account 锁路径
+  （`lockAccountUsers` `FOR UPDATE` + enabled 校验 + 一致 ID/owner 比对），与 `policyWrite`
+  是同一家族。可以理解为对现有单写围栏的"批量化"，没有引入新的、非现有围栏之外的捷径。
+- **检查 4：跨账户读取**。`ListRoleMembersForActor` / `PreviewUserRoleAssignments` /
+  `searchAdminUsers` 三个读取入口都已就授权闸；没有出现"通过 batch 路径可以读到他人 role-membership
+  但单 API 不可读"的二通道。
+- **检查 5：审计/回执旁路**。`policyWriteBatch` 包裹的写入最后都走 `saveReceipt`（除 `CreateRole`
+  类型既有的纯插入路径外），未发现可以既写盘又不留 `policy_receipts` 行的调用点 —— 审计门未开窗。
+
+---
+
+## 5. 重点 3 —— 事务与一致性
+
+`policyWriteBatch` 的事务结构与 `policyWrite`（同文件 line 181）严格同形态：
+
+1. 把 actor 与所有 target owner 加入 owner 集合；
+2. `s.db.Begin()`，defer Rollback；
+3. `lockAccountUsers(tx, owners...)` —— owner 字典序排序后逐个 `FOR UPDATE`，规避锁顺序；
+4. 校验 `actorAccount.Enabled` 与每个 target `target.Enabled && target.ID == userID`；
+5. 读 `authority_state.authority_epoch`（PG 下 `FOR UPDATE`）；
+6. 调用上层闭包；
+7. 闭包负责回写 epoch 与保存 receipt；
+8. `tx.Commit()`。
+
+提交或回滚边界：
+
+- `AssignUserRolesBatch`：验证循环 + rebind 循环均在同一事务；任何一次 `ErrAccountForbidden /
+  ErrConflict / ErrInvalidRolePolicy` 都立即返回事务回滚；`rebindUserRoleTx` 内的
+  `UPDATE users SET state_version=state_version+1 WHERE id=? AND state_version=? AND enabled=?`
+  在 SQL 层提供最后一道乐观并发；批内任意用户状态版本与 `expectedStateVersion` 不匹配即整批回滚。
+- `PatchRolePermissionsBatch`：每个 item 走 `patchRolePermissionsTx`，内部 `roleTx(... true)`；
+  `s.upsertRolePermissionsTx` 按 patch 语义只写 patch 列表中的行（未在 patch 列表的行保持原样
+  不动 —— 这与"显式 patch"语义对齐，不会误把删除当作新增）；`UPDATE roles SET role_version=role_version+1
+  WHERE role_id=? AND role_version=?` 拒绝过期；随后 `checkCapabilityAssociationTx(tx, nil, roleIDs, nil)`
+  —— 只检查涉及的 role 列表的 project.create + linked 关联。
+- `CreateRoleCopyAndAssign`：源 role row 锁、新 role insert、`upsertRolePermissionsTx(... nil ...)`、
+  重新把 `items[].RoleID = roleID`（设置后立即调用 `assignRolesTx`）然后 `checkCapabilityAssociationTx`。
+  关闭源已有的 project.create 又把 copy 设成非 creator 的情形被显式拒绝
+  （`sourceWasCreator && !copyIsCreator → ErrInvalidRolePolicy`），这避免了"复制即失去能力"
+  的伪操作混淆。
+
+`current→after` 增量计算是否会把删除误判为新增：
+
+- `previewRolePermissionsTx`：用 `current = s.rolePermissionBitsTx(tx, role.RoleID)` 与
+  `next = normalizePermissionChanges(item.Changes)`，合并 `after`，对所有 `catalog.Catalog()`
+  内动作比对 `Before/After` 状态不同者写入 `Changes`；删除本质上等同"原本某 row 状态 X，目标 Y"，
+  不会进入 `Changes` 错查为"add"（因为 `current` 中已有 row）。
+- `patchRolePermissionsTx`：以 `current` 为基础 `after` 起点，`patch` 覆盖 `after`；`upsertRolePermissionsTx`
+  对比 `current`/`after` 后只对真正变化者写。删除语义上等同于"原 row 留在 patch 之外即不动"
+  （patch 不写删除显式动作，故删除行为是 patch 之外的子集）—— 这是 patch 语义而非 replace 语义，
+  在端口注释里有显式说明 (`// Only listed actions change; every unlisted row of the role stays exactly as stored`)。
+
+回滚完整性（基于代码路径核查，每条都在收到 err 时让事务回到 Begin 状态，因为没有分支绕过 defer
+`tx.Rollback()`，且所有写入函数都用同一 `tx`）：
+
+- `policyWriteBatch`：`tx.Commit()` 之前的任何 error 都回滚；commit 失败由 defer 再 Rollback 兜底。
+- 三个写 store 函数都没有副作用排序的反向操作（除 rebindUserRoleTx 之外）。
+
+未验证：未运行 `go test ./...` —— 见"未验证"节。
+
+---
+
+## 6. 重点 4 —— 审计与回执
+
+- 三个写 API 都调用 `policyWriteBatch` 并在闭包内 `saveReceipt(tx, actorAccount.ID, key, operation, requestHash, out)`，
+  写入 `policy_receipts` 表（既有 main 表）。
+- 操作名分别用 `"role.permissions.batch_patch"`、`"user.role.assign.batch"`、`"role.copy.assign"`，
+  都是独有的操作标签；replay 通过 `(actor_user_id, idempotency_key)` 复合唯一索引保证幂等。
+- `replayReceipt` 在 hash 不一致时返回 `ErrConflict`；与 `TestRolePolicyIdempotencyKeyCannotChangeRequest`
+  既有的幂等语义一致 —— 同样 key + 不同 request 必然拒收。
+- `PolicyReceipt` 与 `RolePermissionBatchReceipt` 都嵌入了 `PreviousRoleVersion` / `Changes` /
+  `KeptLinkedActions` 等可复核字段。回执包含 `ReceiptID` (`newID("receipt")`) 与
+  `AuthorityEpoch = epoch+1`，方便把回执与下一次 authority epoch 增量对齐。
+- `CreateRoleCopyAndAssign` 在写盘后用 `s.roleTx(roleID, false)`（不带锁，二次 snapshot）+ 
+  `s.rolePermissionRecords(...)` 重新读 `role_permissions` 完整集合（含历史 audit 行），计算
+  `ProjectAccessOf`，保证回执中 `ProjectAccess` 与 `RoleAdmin`/`ListRoles` 共享投影。
+- `RolePermissionConflict` 仅在预览路径出现 —— 由 `state.conflicts()` 推导（既有的
+  `capabilityConflict`、`capabilityConflictReason`），与 `checkCapabilityAssociationTx` 共用同一
+  套冲突识别逻辑。冲突原因 `使用此角色的用户已直接获授创建项目...` / `创建项目需要本人项目...` 都是
+  user-facing 中文，不暴露内部 ID。
+- 审计旁路检查：grep 没有发现 `tx.Exec(...)` 后绕过 `saveReceipt` 的旁路；
+  `policyWriteBatch` 接受的是一个闭包，闭包内未调用 `tx.Commit()`（commit 由 `policyWriteBatch` 唯一持有），
+  这确保 batch 写后必须走 `saveReceipt` 才能 commit 落盘。
+
+未发现绕过审计的写入。
+
+---
+
+## 7. 重点 5 —— 与 #228/#234 的关系
+
+#228（Add read-only role options, a member roster directory and a removed-member send refusal）
+
+引入：
+- `pkg/extension/RoleOption` / `RoleOptionsProvider.ListRoleOptions`（read-only enabled
+  role directory；走 `h.caps.st.ListRoles` 投影为 `roleId+name`）
+- `pkg/extension.AccountDirectoryPurposeProjectRoster`（project roster 枚举）
+- `internal/server/server.go` postMessage 中 "not-project-member" 路径
+
+端口新增：
+
+- `RolePermissionPreviewInput` / `RolePermissionPreview`（管理员对角色权限的变更预览）；
+- `RolePermissionPatchInput` / `RolePermissionBatchReceipt` / `RolePermissionBatch`
+  （管理员的多角色权限 patch）；
+- `RoleCopySource` / `RoleCopyAssignment` / `RoleCopyAssignResult`（复制并指派）；
+- `UserRoleAssignmentInput` / `UserRoleAssignmentResult` / `UserRoleAssignmentBatch`
+  （多用户角色指派）；
+- `UserRoleAssignmentPreview`（指派预览）；
+- `RoleMember` / `UserRoleSummary`（admin 视角下的成员/角色摘要）；
+- 新增 API：permissions/preview、permissions/batch、copy-assign、{roleId}/members、
+  users/role-assignments、users/role-assignments/preview，并给 users/search 加上 role 投影。
+
+没有发现重复或冲突：#228 的 `RoleOptionsProvider.ListRoleOptions` 仍是非 admin 派发面
+（"trust a trusted Host"，且"callers still authorize their own domain action"），
+本端口的 7 个 admin API 在 main 当前路由表里尚不存在；`GET /api/admin/roles/{roleId}/members`
+是 admin 视角的成员名册，没有触及 `AccountDirectoryPurposeProjectRoster` 的项目名册枚举。
+`UserRoleSummary` 是 store-side projection 类型，没有出现在 `pkg/extension/surface.txt` 新增
+位置上（不污染扩展面）—— 这一点有意的：内部 store 投影不应进入扩展契约。
+
+#234（Land the project access and lifecycle role and work-state work on Backend main）
+
+引入：
+
+- `internal/app/hostcaps.go` 中 `RoleAdminProvider`、`CreateRole/UpdateRole/DeleteRole/...`、
+  `ReplaceRolePermissions` 的派发 Host 实现（与 AdminProvider 一起）；catalog 测试
+  `TestCatalogLinkedActionsStayProjectScopedAndUnprotected` 与 `R2` 的角色模型断言。
+- `internal/authz/service.go` 的 system action 决策函数、`ExplainCapabilities` 投影；
+- `internal/server/project_lifecycle.go` 中 `projectWork` / `lifecycleHost`；
+- 测试 `internal/server/project_iam_integration_test.go`、`role_authorization_test.go`、
+  `roles_test.go`、`explain_test.go` 等。
+
+端口新加的项目 1:1 与 #234 项目没有重叠：
+
+- 不动 `RoleAdminProvider` / `RoleAdminView` schema（仍由既有 `RoleAdmin` 函数读出来）。
+- 不动 `AuthorizeSystem`、`ProjectCreateAction`、`ProjectAccessAction`、`ProjectCreateLinkedActions()`。
+- 不动 `lifecycleHost`、`projectWork`、`ExplainCapabilities`。
+- `TestCatalogLinkedActionsStayProjectScopedAndUnprotected` 添加的测试（catalog_test.go 末尾
+  的 +16 行）仅是个保险钉——验证 catalog 中的 linked 动作仍为 project-scope 且非受保护，
+  与本端口在 `normalizePermissionChanges` / `CreateRoleCopyAndAssign` 里加的限制条件一致。
+- 既有的 `TestRoleProjectCreateLinksFullManagement`、`TestReplaceRolePermissionsAcceptsOnlyProjectAccessBoolean`、
+  `TestCapabilityAssociationRejectsStaleVersionAndMissingRole` 等 R2 / R4 锚点测试没有被
+  改写、删除或弱化（详见 §8）。
+
+---
+
+## 8. 重点 6 —— 测试质量
+
+新测试（14 项，全部新增，未删/未跳过既有断言）：
+
+store 层（`internal/store/role_policy_test.go`）：
+
+- `TestPatchRolePermissionsBatchEnablesAndDisablesAcrossRoles`（happy，双 role 同步切换）
+- `TestPatchRolePermissionsBatchAtomicityRejectsWholeBatch`（一坏拒整批 + 验证两 role
+  维持原样 + epoch 不前进）
+- `TestPatchRolePermissionsBatchStaleVersion`（过期 version 拒整批 + role 维持原样）
+- `TestPatchRolePermissionsBatchRejectsLimitAndIdempotency`（20 上限、空批、同 key 重放返回
+  同一 receipt/epoch）
+- `TestPreviewRolePermissionsMatchesCommitResult`（预览允许/拒绝与 commit 一致）
+- `TestPreviewRolePermissionsRejectsInvalidBatchItem`（非法动作仅在 item 级别报错，不写盘）
+- `TestAssignUserRolesBatchRebindsInOneTransaction`（两人 rebind 在一个事务中，epoch+1 + 
+  同 key 重放 epoch 不变）
+- `TestAssignUserRolesBatchRejectsWholeBatch`（一个用户 state_version 过时 → 整批回滚
+  + 两角色 binding_id 与 state_version 未被改写）
+- `TestPreviewUserRoleAssignmentsJudgesEachItem`（三种 case：成功、state_version 过时、
+  用户不存在；预览不写盘不前进 epoch）
+- `TestListRoleMembersForActorRequiresGrantsAndPaginates`（admin 看见、ordinary 被拒）
+- `TestActiveRolesForUsersReturnsActiveBindings`（仅返回 active binding；结束后不再见）
+- `TestCreateRoleCopyAndAssignCreatesRoleAndBindsInOneTransaction`（happy：新 role +
+  绑定 + epoch+1）
+- `TestCreateRoleCopyAndAssignRejectsWithoutResidue`（覆盖坏 overrides / 坏 name / 坏

+
+---
+
+## 10. 非阻塞建议（advice，不阻断合入）
+
+按"安全优先 → 可靠性 → 测试"排列：
+
+1. **[安全] `assignUserRolesBatch` 缺少"非 admin 调用被 403"的 HTTP 层负测**。
+   `TestBatchRolePermissionPatchOverHTTP` 与 `TestRolePermissionPreviewRequiresPermissionViewOverHTTP`
+   已经验证了"持有弱权限的 actor 拿不到 403"。`assignUserRolesBatch` 与 `previewUserRoleAssignments`
+   仅在 happy 路径上测过（`TestBatchRoleAssignmentPreviewAndCommitOverHTTP`）。
+   建议补一条"持有 `system.roles.view` 但无 `system.roles.assign` 的 actor 调用
+   `/api/admin/users/role-assignments` 收到 403"的测试。预期实现确实会拒绝
+   （`assignUserRolesBatch` 起手 `requireSystemAction("system.roles.assign")`），但缺少语义钉。
+
+2. **[安全] `copyAssignRole` 缺少 HTTP 层负测（任一闸不足被拒）**。
+   当前只有 happy path。建议补：
+   - 仅 `system.roles.manage` + `system.permissions.manage`，缺 `system.roles.assign` → 403；
+   - 仅 `system.permissions.manage` + `system.roles.assign`，缺 `system.roles.manage` → 403；
+   - 仅 `system.roles.manage` + `system.roles.assign`，缺 `system.permissions.manage` → 403。
+   三个闸同时持有的语义在生产代码中已写明，但测试未钉死。
+
+3. **[安全/一致性] `assignUserRolesBatch` 缺 user-missing/role-missing/role-disabled 的负测**。
+   `TestAssignUserRolesBatchRejectsWholeBatch` 仅覆盖 stale-state-version 一种失败模式。
+   store 层 `assignRolesTx` 通过 `roleAssignmentUserMissing` / `roleAssignmentUserDisabled` /
+   `roleAssignmentRoleInvalid` 区分三种原因（preview 路径已经分别测过这三种原因，
+   `TestPreviewUserRoleAssignmentsJudgesEachItem`），但 commit 路径没有显式锁定
+   "bad userId / disabled user / disabled role" 都会回滚。
+
+4. **[可靠性] PostgreSQL 下潜在的锁顺序风险**。
+   `assignRolesTx` / `CreateRoleCopyAndAssign` 内部对每个 item 调用
+   `s.roleTx(tx, item.RoleID, true)`，锁定顺序由 items 切片顺序决定。
+   与 `policyWriteBatch` 内部 `lockAccountUsers` 的字典序 owner 锁不同，role-row 锁顺序
+   没有全局规范化。当两个并发 batch 提交 items 涉及交叠 role 集合但顺序相反时，
+   可能出现 PG 层 `40P01 deadlock_detected`，客户端表现为 500（因为 writeStoreErr 对
+   deadlock 没特殊映射）。SQLite 不受影响。
+   建议（任一）：
+   (a) 批前按 `item.RoleID` 排序后再 `roleTx`，让所有 batch 走同一序；
+   (b) 在 writeStoreErr 中对 deadlock 检测加一条 `502/503` 提示;
+   (c) 把 SQL 锁与 `policyWriteBatch` 的 owner 锁合并成同一把 `pg_advisory_xact_lock`
+       key。在评估其工作量后再决定。
+   当前批大小（≤100）下并发风险不大，但应在 batch 大小被放大或 PG 高并发场景重新审视。
+
+5. **[测试] `ListRoleMembersForActor` 缺跨越多 role 测试**。
+   `TestListRoleMembersForActorRequiresGrantsAndPaginates` 只在单 role + active-vs-inactive
+   验证成员计数；没有测 "两个 role，actor 同时查询 role-A，结果只包含 role-A 成员"。
+
+6. **[风格] handler 层 `listRolePermissionPreview` 的 400 路径**。
+   当 `roles` 为空时，handler 直接 400；store 里 `len(items) == 0 || len(items) > maxRolePermissionPreviewItem`
+   也会返回 `ErrInvalidRolePolicy`。两处都在做相同的合法性检查。这是
+   #228/#234 现有 pattern 的一致沿用，但建议未来统一只用一处。
+
+7. **[风格] `previewUserRoleAssignments` 与 `listRoleMembers` 重复了 cursor 计算**。
+   两处都用 SHA256 over `{Kind, Actor, RoleID, Query, Mode, Status, Revision}` 派生
+   version；HMAC 用 `accountSearchKey` 派 cursor token。建议抽 `roleMembersVersion(actor, roleID, query, mode, status, revision)` helper
+   到 `account_search.go`，避免后续在 `copyAssignRole`、`batchPatchRolePermissions` 等
+   写入响应里再次手写。

+
+---
+
+## 12. 未验证（structural limits of detached-HEAD review-only session）
+
+按 packet 第 3 项要求"未验证的结论写明未验证"。下列条目不是结论本身的缺失，而是本会话
+无法跑通验证路径：
+
+1. **未跑 `go test ./...`**：deps 子模块 gitlink 在本 detached-HEAD 工作区中尚未初始化
+   （worktree 内 `deps/*/` 是空目录），且 packet 禁用 `git submodule init/update`，
+   所以 `go build ./...` 也无法走通。所有"编译通过性"和"测试通过性"的结论均以**静态
+   diff/源码对比**为依据，不以运行为依据。评审者**未亲眼见到测试 PASS 输出**。
+
+2. **未对源 feature 分支作交叉比对**：packet 注明 `feature/iam-perm-ux-backend` "唯一副本
+   已备份"，本工作区没有该分支 ref 也无任何 transport 元数据用于追溯。本评审**仅按 diff
+   与 main 既有语义做正向校验**，不与原 feature 分支逐行比对。
+
+3. **PG dialect 下不跑 `go test ./... -tags pg`**：同上。
+
+4. **`tests.test_shell_pipe_hazard` 不可执行**：模板命令，本仓无对应目录与模块，已注明。
+
+5. **未跑 `make precheck`**：packet 在 Dev 仓推进；本仓为子仓，"独立开发"路径见
+   PROJECT.md 但 precheck 归属于 Dev 仓，本审查会话不对其做运行。
+
+---
+
+## 13. 决定
+
+- `terminal_status`: `completed`（独立审查产出完毕，未改动任何非报告文件；非"BLOCKED"）
+- 审查者 ID：iam-perm-ux-port-independent-review
+- 提交建议：可合入 main（前提是 §10 中 (1)(2)(3) 三条负测在合入前补齐或与跟进任务
+  挂钩 —— 推荐补齐后再合，以避免 main 出现"缺少 admin-grant 校准测试"的退化窗口）

+**Base:** `b4399e3` (merge of candidate `6ba53e4` + `main`)
+**Scope (per packet):** `pkg/extension/project_context.go`, `internal/store/context_manifest*`,

+`internal/workflow` (judge + consumption points), `internal/ctxasm/`,

+
+The patch is **purely additive / strengthening** of the r1 (candidate `6ba53e4`) revision. The
+only existing-file edits are:
+
+1. `internal/runmgr/project_context.go` — three narrow inserts inside `recheckManifest`:
+   * `ctx.Err()` re-check before the textual-claim walk,
+   * the textual-claim walk itself (recomputes `sha256(item.Text)` for every `current.Items[i]`
+     and refuses if it doesn't equal `used.InputSHA256`),
+   * final `return ctx.Err()` after a successful recheck (fail-closed on late cancellation).
+   No removal of any prior safety; nothing in `ProjectContext`, `SaveContextManifest`,
+   `BindProjectStepOutput`, `VerifyProjectStepOutput` was changed.
+
+2. `internal/store/context_manifest.go` — adds `requireRecheckableSources` and a single
+   call in `appendContextManifest`. No existing branch removed.
+
+3. `internal/runmgr/project_context_test.go` — one line tightened: `SourceHash: "h2"`
+   added to a fixture so the gate would let a benign receipt through. The test was being
+   held by the new gate and the fixture now mirrors `requireRecheckableSources`'s
+   minimum-identity rule; the original assertion logic is unchanged.
+
+Everything else (`internal/app`, `cmd/storage-migrate`, all new `*_test.go` files) is
+either strictly new test coverage or an idempotency assertion in an existing test.

+
+---
+
+## 2. Findings
+
+### BLOCKING
+
+*None.*
+
+The r1 patch threads the three previously identified gaps:
+
+1. (Provider echo) the textual-claim walk in
+   `internal/runmgr/project_context.go:138–163` plus
+   `internal/runmgr/project_context.go:144–148` (sha recompute) closes it.
+2. (Receipt gate) `requireRecheckableSources` in
+   `internal/store/context_manifest.go:87–107` enforces identities on **every**
+   append.
+3. (Failure modes) `ctx.Err()` is now consulted **twice** in `recheckManifest`
+   (lines 113 and 183) so late cancellation after a successful structural pass
+   still rejects; the deadline-bounded call to `Recheck` in
+   `internal/app/project_context.go:136–143` enforces the 3 s ceiling from the
+   host side.
+
+### MAJOR
+
+*None.* The recheck call site in `internal/wfcompile/project_sources.go:18–56`
+correctly enumerates each persisted prompt step attempt and delegates to
+`VerifyProjectStepOutput`, which itself calls `recheckManifest`. The
+`{{steps.X.output}}` interpolation in `internal/wfcompile/host.go:559–584` is
+rendered **after** `verifyPriorWorkflowOutputs` has already bound and revalidated
+every prompt step's source — see `host.go:102–110` for the strict-mode gate.
+
+### MINOR
+
+| # | File:line | Concern | Suggested treatment |
+|---|-----------|---------|---------------------|
+| M-1 | `internal/runmgr/project_context.go:142` | `if len(current.Items) != len(m.Included) || len(current.Evidence) != len(expectedRefs) || !slices.Equal(current.Missing, m.Missing)` — `current.Missing` ordering is required to be *identical*, not just set-equal. A benign reorder would fail closed, which the spec endorses but is worth flagging because it impacts provider update paths. | Document the fail-closed contract on `ProjectContextSourceRechecker`; or sort `m.Missing` before comparison. |
+| M-2 | `internal/runmgr/project_context.go:170–175` | The `projectEvidenceReader` `break` after a hash mismatch falls through to the **outer** `for _, used := range m.ReadEvidence`. Each `used` is then matched against `current.Evidence` once. Correct, but the inner break on the *no-match* path (`continue` is implicit because the body never executes `break`) could trigger `match` zero times for a `used` whose `current.Evidence` carries a newer `SourceID` revision. The test matrix covers the common cases; consider negative-testing the "revoked source but same ReferenceID" case explicitly. | Add an explicit negative test asserting `VerifyProjectStepOutput` rejects when `current.Evidence` carries a same-ID ref whose `Hash` differs from `used.SourceHash`. |
+| M-3 | `internal/runmgr/project_context.go:182` | `return ctx.Err()` is the final statement after a successful structural pass. This is fail-closed and the spec wants it, but it makes the function *noisy* in unit tests that cancel between passes — it returns `context.Canceled` rather than `nil` for a *successful* recheck whose context expired post-check. | If a future change relaxes the rule, comment this line as load-bearing. |
+| M-4 | `internal/app/project_context.go:118–120` | `s == nil`, `Actor==""`, `ProjectID==""`, *and* `Goal!=""` all return the same generic error. Helpful for the spec but harder to diagnose. | Differentiate the four conditions for host-side observability. |
+| M-5 | `internal/store/context_manifest.go:67–80` | The terminal-state match query requires `attempt_id=? AND delivery='attempted' AND owner=? AND target_id=? AND project_id=? AND input_sha256=?` — but `input_sha256` is not the canonical identity of a model request; the actual identity is `(attempt_id, project_id, owner, target_id, input_sha256)`. That is fine, but a malicious plugin that could write a same-`input_sha256` row with a different `attempt_id` would be blocked by the `attempt_id` equality check; however, **the test for cross-`attempt_id` reuse** is in `internal/store/context_manifest_test.go:45` (attempt reused across target) and not for the other columns. | Add unit coverage that confirms re-using `attempt_id` across `project_id` or `owner` also fails. |
+| M-6 | `internal/wfcompile/host.go:559–584` (`renderRefs`) | `renderRefs` is a runtime resolver used by `doTool` and `doArtifact` (both `strict=true`). `doCard` and `doScript` also reach `renderRefs` indirectly via the `out_<id>` field population; if `doScript` ever feeds `{{steps.X.output}}` into a non-strict step, the trust barrier is the early guard. Currently strict covers every consumer; this is an *invariant*, not a defect. | Document this invariant on `renderRefs`. |
+
+### Observations (informational)
+
+* **Test coverage added in r1 is comprehensive against the spec.** Each requirement
+  has at least one named test whose prefix matches the requirement number:
+  timeout (3 s) → `TestProjectSourceRecheckFailsClosedAtThreeSecondCeiling`,
+  refused/denied/cancellation → `…RefusalDenialAndCancellation`,
+  cross-guard multi-round → `TestProjectCrossGuardRechecksEarlierRoundAfterLaterSource`,
+  receipt gate → `TestSaveContextManifestRejectsUnrecheckableModelInput`.
+* **`internal/ctxasm/` is not in the change set.** The code there is the
+  general-purpose context assembly; the project context manifest construction
+  happens in `internal/projectcontext/Assemble` and `internal/app/project_context.go`
+  (`assembleWorkCompletionWithEvidence`). `ctxasm.AssembleInput` does not
+  reconstruct or re-authorize project sources, and it has not been changed. The
+  two layers do not overlap in their trust boundary: ctxasm consumes agent
+  messages for the engine-level call, project-context generates the trusted
+  receipt the judge revalidates.
+* **`internal/workflow/`** contains only the `Render` / `RenderRaw` /
+  `RenderStep` placeholder expansion. The judge's actual call into
+  `VerifyProjectStepOutput` lives in `internal/wfcompile/host.go` (`doCritic`,
+  `applyScriptPlan`) and `internal/wfcompile/project_sources.go`
+  (`verifyPriorWorkflowOutputs`). The workflow render path runs **before** the
+  host step in `Run`; for project runs the host step calls
+  `verifyPriorWorkflowOutputs(strict=true)` first, so a stale `{{steps.X.output}}`
+  interpolated string never reaches the model without `VerifyProjectStepOutput`
+  having revalidated its source. This matches requirement (3).
+* **`cmd/storage-migrate/main.go` interactions:** `cmdBackup` and `cmdMigrate`
+  both call `refuseCandidateRawContextScope` at lines 295–329 before doing
+  anything else. The new `TestMigrateTrustedContextManifestWithoutRawScope`
+  integration test exercises an idempotent re-run (`cmdMigrate` called twice
+  with same `--migration-id --source --target`) and asserts `len(receipts) == 2`
+  and the absence of `resolve_goal`/`resolve_target_id` columns on the PG side.
+  The PG schema bootstrap (`store.OpenPostgres`) is unchanged and already creates
+  the trustworthy schema without those columns; the `refuseCandidate…` guard
+  blocks any source that still has them.
+* **Concurrency / resume paths:** `recheckManifest` and `VerifyProjectStepOutput`
+  are stateless on the `runCtx` (they only read `c.run`, `c.mgr.st`,
+  `c.mgr.projectSourceRechecker`, `c.mgr.projectEvidenceReader`). Concurrent
+  goroutines are safe modulo a stateful provider; the new
+  `TestProjectSourceRecheckConcurrentCancellationFailsEveryWaiter` exercises 6
+  workers on a shared `runCtx` and asserts every waiter observes the
+  cancellation. Background resume is exercised through re-reading the run row
+  from the store (`trustedProjectContextRequest`) on every recheck call — there
+  is no path that can resurrect a stale in-memory run identity.
+

+
+## 3. Per-file reviewed verdict
+
+| File | Change in r1 | Findings |
+|------|--------------|----------|
+| `pkg/extension/project_context.go` | No change since r0 (candidate `6ba53e4`) — already added `ProjectContextSourceRechecker` interface, `ProjectContextSourceRecheckRequest`/`Result`, never-contains-text contract on `Bundle`. | Pre-existing contract matches requirement (1); no r1 regression. |
+| `internal/store/context_manifest.go` | `+24`: `requireRecheckableSources` + call site. | **PASS** for (4), (5). |
+| `internal/store/context_manifest_gate_test.go` | New file, `+45`. | **PASS** — exercises every missing-identity variant (incl. `OfferedReferences` w/o `ID`, `ReadEvidence` w/o `ReferenceID`/`Revision`). |
+| `internal/runmgr/project_context.go` | `+24/-2`: 3 narrow inserts into `recheckManifest`. | **PASS** for (1)–(7). Minor M-1/M-2/M-3 above. |
+| `internal/runmgr/project_context_test.go` | `+1/-1`: one fixture row received `SourceHash` to satisfy the new gate. | **PASS** — change keeps the assertion intent intact. |
+| `internal/runmgr/project_source_recheck_test.go` | New file, `+349`. | **PASS** — covers (1)/(2)/(3)/(6). The concurrent-cancel test specifically exercises M-3's intent. |
+| `internal/app/project_source_recheck_test.go` | New file, `+97`. | **PASS** — addresses the 3 s deadline, provider refusal, cross-project, missing-actor rejection, and the registered-vs-typed PluginID enforcement (M-4 covered). |
+| `internal/app/project_context.go` | No change in r1 — the existing `recheck` slot already wired the `extension.ProjectContextSourceRechecker` interface and the 3 s deadline. | **PASS** for (3)/(6)/(7). |
+| `cmd/storage-migrate/integration_test.go` | `+10`: idempotency assertion for context manifests. | **PASS** for (5). |
+| `cmd/storage-migrate/main.go` | No change in r1 — `refuseCandidateRawContextScope` already gates v34/v35 sources. | **PASS** for (5). |
+| `internal/workflow/` (render.go, validate.go, registry.go) | No change in r1. | Render is called via `RenderStep` in `wfcompile`, then host `Run` calls `verifyPriorWorkflowOutputs`. **PASS** for (3). |
+| `internal/wfcompile/host.go`, `project_sources.go`, `project_backend.go` | No change in r1 — strict-mode `verifyPriorWorkflowOutputs`, `doCritic` (`judge`), and the `{{steps.X.output}}` `renderRefs` runtime path are already gated. | **PASS** for (3). |
+| `internal/ctxasm/` | No change in r1 — `ctxasm` is not part of the project trust boundary. | **PASS** (out of scope by design). |
+
+---
+
+## 4. Concurrency & recovery deep dive (per spec)
+
+* **Race on `c.projectContextReq`.** Guarded by `c.projectContextMu`
+  (`internal/runmgr/project_context.go:187–196`). `recheckManifest` calls
+  `trustedProjectContextRequest` which builds a fresh `req` value and returns
+  it; the assignment to `c.projectContextReq` happens via `setContextRequest`
+  **only** when a fresh `Resolve` runs. A recheck that races a fresh `Resolve`
+  could observe the *prior* scope value, but the recheck compares against
+  `m.AttemptID`/`m.ProjectID` (persisted) — never against the in-memory scope
+  identity.
+
+* **Read reauthorization races.** `projectEvidenceReader` is called inside
+  `recheckManifest` and `SaveContextManifest`. Both compare the freshly-read
+  `sha256(evidence.Text)` against the persisted `used.InputSHA256`. The reader
+  cannot impersonate a previously-recorded body because the hash is recomputed
+  every time.
+
+* **In-flight cancellation.** `recheckManifest` consults `ctx.Err()` **before**
+  the textual-claim walk (line 113) and **after** (line 183). The `Recheck`
+  provider call itself is wrapped in a 3 s `context.WithTimeout` in
+  `internal/app/project_context.go:136–143`. `TestProjectSourceRecheckConcurrentCancellationFailsEveryWaiter`
+  exercises 6 concurrent rechecks against a single shared `runCtx` and confirms
+  cancellation propagates to every waiter.
+
+* **Backend resume path.** `trustedProjectContextRequest` re-reads the run and
+  conversation from `c.mgr.st` on every call. `internal/runmgr/project_context_test.go`
+  has `TestProjectContextResumeReloadsCurrentVersionAndAuthorization` which
+  constructs a *second* `runCtx{mgr:m, run:reloaded}` for an `Interrupted` run
+  and confirms the resume path uses the current authorization (not the
+  frozen-in-memory snapshot).
+
+* **Workflow sink ambiguity.** `internal/wfcompile/project_sources.go:88–141`
+  records the step start, *invalidates* any prior `WorkflowStepSource` binding
+  on each start, and marks the step `ambiguous` whenever two start events
+  coexist in the in-progress set. The downstream `BindProjectStepOutput` is a
+  no-op when `ambiguous`, leaving the judge to fail closed.
+  `internal/store/workflow_step_source.go:65–110` enforces a bitmask
+  `state == 3` (bits `attempted` + `responded`) for every attempt ID covered
+  by the step; `TestProjectStepOutputRejectsUnsettledAttemptInSameStep`
+  exercises the `attempted` and `unknown` mixed storage cases.
+
+* **Recovery store under interruption.** The recheck call re-reads from
+  `ListContextManifests` every time (`internal/runmgr/project_context.go:52`),
+  so a row committed by an in-flight `SaveContextManifest` is visible to the
+  next cross-guard call but invisible to a prior one. There is no `BEGIN/END`
+  window during which `recheckManifest` could observe an inconsistent set of
+  receipts because each row's gate (`requireRecheckableSources`) is applied
+  in the same SQL transaction as the insert.
+
+---
+
+## 5. Verdict
+
+**APPROVED for merge into `feature/w6-x1-source-recheck`** as far as the reviewer's
+evidence permits. No blocking or major issues identified. The single grade-M
+observations are refinements, not corrections; none block the safety property
+the revision claims.
+
+The reviewer makes no claim about CI green-ness; that requires running the
+test suite. Tests were read; not run.
