fix(agent): Chat Agent 全链路 P0-P5 整改

封堵鉴权旁路与导出 IDOR，DocGov 改服务端身份；对话层 PendingAction 接真实 docgov/taskrun；修复流式租约假死与会话级任务流；加固配置/doc_id/NULL；补齐 slog 与测试；前端 ErrorBoundary 与受控文档重试。

+# Chat Agent P6 Backlog Issues
+
+以下项不阻塞当前发布，建议分别开 issue 排期：
+
+- **B5** 报价模块接入轻量复核与输入范围校验（`internal/quote/`）
+- **A5/A6** 小队工作流支持非关键步骤降级；并行 trace 序号改单次加锁读-算-写（`internal/squad/`）
+- **A7** 将中文注释中的已知限制迁移为正式 issue
+- **D3** 摘要引擎替换为语义摘要（依赖模型接入，需单独评估）（`internal/ctxmgr/summarizer.go`）
+- **D5** 知识库按环境隔离方案评估（当前三环境共享 KB 为 intentional 架构）
+- **D7** 对话数据留存期限与敏感字段加密（先对齐合规再定技术方案）

+# Chat Agent 全链路修复整改 测试报告
+
+## 一、 测试背景 (Background)
+
+依据《Chat Agent 修复路线图》完成 P0–P5 整改：鉴权旁路封堵、DocGov/导出 IDOR 收敛、PendingAction 对话接线、流式租约修复、前端会话隔离、配置密钥校验、doc_id 并发与 NULL 兜底、可观测性 slog、前端 ErrorBoundary/受控文档重试等。
+
+## 二、 测试目标 (Test Objectives)
+
+- P0：无凭证 401；跨用户导出 403；DocGov 使用服务端身份
+- P1：`PendingAction` 由 Session 执行 docgov/taskrun
+- P2：流式假死租约过期；`useTaskRunStream` 按 session 隔离
+- P3：非 dev/test 弱密钥启动失败；`CreateOrGetDocument` 并发单记录
+- P4：intent/coordinator/taskrun slog 与 taskrun 单测
+- P5：ErrorBoundary、docLoadError 重试、MessageBubble memo、AppShell 880px
+
+## 三、 测试方案与环境 (Test Plan & Environment)
+
+- OS：darwin 25.6.0；Go 1.27；Node vitest 5
+- 后端：`AgentBackend=stub` 单元/集成；KB 离线降级
+- 层级：`go test` 包级回归 + 前端 `npm run test`
+
+## 四、 预期结果 (Expected Results)
+
+| 用例 | 预期 |
+|------|------|
+| 无 Bearer 调 export-source | 401 |
+| 用户 2 导出用户 1 会话 | 403 |
+| test_manager 上游 approved 后 workflow run | 200 |
+| PendingAction review_approve | 状态 → approving |
+| 并发 CreateOrGetDocument 同 doc_id | 单记录 |
+
+## 五、 实际测试结果与判定 (Actual Results & Evaluation)
+
+### 5.1 P0 导出 IDOR
+
+- **输入**：admin token 注入 sess；用户 2 请求 export-source
+- **输出**：401（无 token）；403（跨用户）
+- **判定**：PASS
+
+### 5.2 P1 action_executor
+
+- **输入**：reviewing 文档 + `docgov.review_approve` PendingAction
+- **输出**：`DocState=approving`
+- **判定**：PASS（`TestExecuteAction_DocGovReviewApprove`）
+
+### 5.3 P2/P3 workflow + doc_id
+
+- **输入**：动态 projectID + stub backend workflow run
+- **输出**：HTTP 200；lineage 非空
+- **判定**：PASS（`TestProjectWorkflow_TestManagerAndLineageStale`）
+
+- **输入**：两 goroutine 并发 `CreateOrGetDocument`
+- **输出**：同一 doc_id，GetDocument 单条
+- **判定**：PASS（`TestCreateOrGetDocument_ConcurrentSameDocID`）
+
+### 5.4 前端
+
+- **输入**：`vitest run` 单文件
+- **输出**：chatWindowArtifact 1/1 PASS
+- **判定**：PASS（全量并行偶发 worker 失败，单文件稳定）
+
+## 六、 自动化测试套件汇总 (Test Suite Execution)
+
+```
+go test ./internal/server/ -run 'TestServer_ReplyExportAPI|TestServer_ChatUnread|TestProjectWorkflow|TestHandleRunProjectWorkflow'  → PASS
+go test ./internal/chat/ ./internal/bizdev/ ./internal/coordinator/ ./internal/config/ ./internal/taskrun/ ./internal/ctxmgr/ → PASS
+```
+
+注：`TestE2E_*` / `TestPiAgent_*` 需真实 pi-agent 环境，本轮 stub 回归未将其计入通过统计；上线前须按铁律补真实 Agent 端到端验收。
+
+## 七、 测试结论与后续优化建议 (Conclusion & Next Steps)
+
+- P0–P5 代码整改与 stub 层回归通过，可合并 dev。
+- 建议：在 dev 容器内跑真实 MiniMax-M3 全链路 E2E；修复 `npm run test` 并行 worker 偶发失败；P6 backlog 按 `.doc/backlog/chat-agent-p6-backlog.md` 开 issue。
