+# 受控文档三权流转控制完善（审核/批准/归档/重开 + 锁定期补充消化）
+
+> 落地版 · `task_id=doc-review-lifecycle-2026-09-25` · 2026-09-25
+
+## 1. 目标
+
+在既有四态状态机（`drafting→reviewing→approving→approved`）上补齐四条缺口，不重造状态机：
+
+| ID | 缺口 | 处理 |
+|---|---|---|
+| G1 | 锁定期补充误生成提案后卡死 | 积压账本 + `skipped_locked` |
+| G2 | 职责人流转零通知 | 生命周期事件 + 收件人按槽位路由 |
+| G3 | 批注不落库 / 权限过宽 | 阶段化矩阵 + resolve API + 前端落库 |
+| G4 | 重开无 UI / 审批人仅创建人 | Approver 优先 + 创建人兜底 + 前端入口 |
+
+## 2. 状态机（语义不变，正交积压）
+
+```mermaid
+stateDiagram-v2
+    drafting --> reviewing : submit_review
+    reviewing --> approving : review_approve
+    reviewing --> drafting : review_reject
+    approving --> approved : approver_approve
+    approving --> reviewing : approver_reject
+    approving --> drafting : approver_reject
+    approved --> drafting : reopen_approve
+```
+
+积压表 `document_pending_supplements`（goose `00072`）独立于 `document_records` 状态列。回 drafting 时 `DigestPendingOnReturnToDrafting` 标记 digested 并通知 author。
+
+## 3. 锁定期补充闭环
+
+1. `CreateFromSupplement`：`LockedSnapshot = IsLocked || state != drafting`；`BusySnapshot` 仍为编辑租约。
+2. `Decide`：锁定项 → `OutcomeSkippedLocked` + `PendingLedger.Record` + 知会当前职责人（reviewing→reviewer，approving/approved→approver，缺位→author）。
+3. 回 drafting（驳回/重开）→ 消化积压 + `pending_supplements` digest。
+
+## 4. 流转通知收件人
+
+| 事件 | 收件人 |
+|---|---|
+| `document.review_requested` | ReviewerID |
+| `document.approval_requested` | ApproverID |
+| `document.rejected` / `reopened` / `pending_supplements` | AuthorID |
+| `document.approved` | AuthorID |
+
+`docnotify.RecipientForDocEvent` 统一解析；lifecycle hook 在 `SubmitForReview` / `Review*` / `Approver*` / `ReopenForRevision` 成功后触发。
+
+## 5. 批注权限矩阵
+
+| 状态 | 可新增批注 |
+|---|---|
+| drafting | author, reviewer |
+| reviewing | reviewer, author（回应） |
+| approving | approver, reviewer |
+| approved | 禁止新增（`ErrDocumentLocked`） |
+| viewer | 恒只读 |
+
+`POST /api/v1/docgov/comments/{id}/resolve`：author 在 drafting 可 resolved；reviewer 可 reopen。
+
+## 6. 重开审批
+
+`handleProjectTraceReopenApprove`：文档 `ApproverID` 且成员仍 active → 可批；全部批准人缺位/退出 → 项目创建人兜底。前端 approved 态提供「申请再修订」。
+
+## 7. 明确不做
+
+- 不新增第五状态、不改 `IsLocked` 语义、不引入批量审批委托、不动 FAV 归档链路。

+# 受控文档三权流转控制完善 测试报告
+
+## 一、测试背景 (Background)
+
+补齐受控文档审核/批准/归档/重开链路与锁定期补充积压闭环（G1–G4），对应设计见 `.doc/system-design/2026-09-25-doc-review-lifecycle-design.md`。
+
+## 二、测试目标 (Test Objectives)
+
+1. 锁定态补充 → `skipped_locked` + 积压落账，不生成提案。
+2. 流转通知收件人按职责槽位路由。
+3. 批注阶段化权限矩阵（负例：viewer / approving 期 author）。
+4. 重开审批：Approver 优先，缺位回退创建人（代码路径；HTTP 集成待环境）。
+5. 前端批注策略与 API 形状。
+
+## 三、测试方案与环境 (Test Plan & Environment)
+
+- OS: Linux；Go 短测；前端 `tsx --test`。
+- 层级：工程单元 / 包级短测（验证契约「工程工具验收补充」）。
+- **真实 PI E2E**：本回合未获授权共享环境与产品 Runner 槽位，记为 **未运行**（不得冒充 PASS）。
+
+## 四、预期结果 (Expected Results)
+
+见各用例断言。
+
+## 五、实际测试结果与判定 (Actual Results & Evaluation)
+
+### 5.1 Go：`internal/docgov` / `supplementimpact` / `app/docnotify`
+
+- **测试输入**：`go test ./internal/docgov/... ./internal/supplementimpact/... ./internal/app/docnotify/... -count=1`
+- **实际输出**：
+
+```text
+ok  	chat-agent-system/internal/docgov	0.003s
+ok  	chat-agent-system/internal/supplementimpact	0.002s
+ok  	chat-agent-system/internal/app/docnotify	0.002s
+```
+
+- **评价判定**：PASS（含 `TestDecideLockedSkipsAndRecordsPending`、`TestAddCommentStageMatrix`、`TestRecipientForDocEvent`、`TestHandleReviewRequestedRoutesToReviewer`）
+- **性能与耗时**：约 1–2s 量级冷启动后单包毫秒级
+
+### 5.2 Go：`internal/server` short
+
+- **测试输入**：`go test ./internal/server/ -count=1 -short`
+- **实际输出**：`ok chat-agent-system/internal/server`（约 19s）
+- **评价判定**：PASS
+
+### 5.3 前端 commentPolicy
+
+- **测试输入**：`./node_modules/.bin/tsx --test src/lib/commentPolicy.test.ts`
+- **实际输出**：4 tests pass（stage matrix / viewer / resolve gates）
+- **评价判定**：PASS
+
+### 5.4 真实 PI E2E 全链
+
+- **评价判定**：未运行（待授权环境：编制→送审→锁定批注→驳回→积压消化→再送审→批准→归档→重开）
+
+## 六、自动化测试套件汇总 (Test Suite Execution)
+
+| 套件 | 结果 |
+|---|---|
+| `go test` docgov / supplementimpact / docnotify | PASS |
+| `go test ./internal/server -short` | PASS |
+| `commentPolicy.test.ts` | PASS |
+| 产品 PI E2E | 未运行 |
+
+## 七、测试结论与后续优化建议 (Conclusion & Next Steps)
+
+- 单元与短测覆盖 G1–G3 主路径与负例；G4 审批人逻辑已落代码，需在获授权环境用真实成员/退出成员补 HTTP 验收。
+- 合入后建议：跑 goose `00072`、再跑一次真实 PI 全链并回填本节 5.4。
