+- Wave 0–4 服务端/单测已在 `dev`（`fix/conversation-intent-state` 是祖先）。
+- 前端 5s 租约轮询：`web/src/App.tsx`。

+- UI busy 文案：`BlockRenderer` / `DeckDrawer`「编辑中」。
+- 只读总结真实 PI（用例 H）已签；项目 143 诊断污染未删。
+
+## 未完成
+
+- 浏览器刷新恢复与双标签租约可见性（报告用例 E）。

 ### 用例 E：真实 PI + 浏览器刷新/双标签页

- **Input**: 真实 PI 只读总结已执行；浏览器刷新/双标签页待执行
- **Actual Output**: 只读总结见用例 H；刷新和 busy 可见性尚无浏览器证据
- **Evaluation**: PARTIAL
+- **Input**: 新建项目 `INTENT双标签-061002`（id **6275**，**禁止 143**）/ `sess-p6275-u10`；Tab A `POST /api/v1/tasks/runs`「请开始编写用户初始需求表」真实 `pi-agent`；租约出现后 Tab B 再 POST；浏览器双标签打开同一项目
+- **Actual Output**:
+  - health/ready schema **38**、`agent_backend=pi-agent`
+  - Tab A `202` `run_1789452602295343365` status=running；2ms 内 `lease_holder_type=squad`
+  - Tab B HTTP **409** `DOC_BUSY`，响应无 `run_id`；PG `task_runs` 仅 1 行
+  - 聊天窗 assistant `error_info.code=DOC_BUSY` 且 `actions=[]`，另有 `task_status=running` 占位；再次 GET window 同集
+  - 真实 PI **completed**（约 280s，质量 100）；租约在终态探测后 **1ms** 已空（无需客户端刷新）
+  - 终态后再 GET window：DOC_BUSY 卡仍 `actions=[]`，无重试动作
+  - 浏览器（Docker Playwright，宿主机缺 libatk）：双标签可见「本文档正由【项目助手】编辑/生成中」、聊天 `DOC_BUSY`、发送按钮 disabled、刷新后仍无重试。截图 `assets/2026-09-15-conversation-intent-dual-tab/screenshots/`
+- **Evaluation**: **PASS**
+- **性能与耗时**: API 活验 281s；Docker UI 4.4s。产物：`assets/2026-09-15-conversation-intent-dual-tab/live.json`、`playwright-docker.json`
+- 诊断污染：`sess-p143-u9` **未**写入、未删除历史探针

 ## 七、 测试结论与后续优化建议 (Conclusion & Next Steps)

-代码级、构建门禁及真实 PI 只读总结已通过；原句不会创建任务或租约。最终 dev 镜像重建后 `/ready` 为 HTTP 200；只读复核确认用户原会话最大消息 ID 仍为 567、隔离 fixture 会话/消息/run 均为 0、project 143 无有效文档租约。尚不能标记发布完成：浏览器刷新恢复、双标签页租约可见性与并发写“不新增第二 run”仍需补录。真实会话中的诊断消息与误启动产物只记录证据，不在未获确认时删除或回滚。
+代码级、构建门禁、真实 PI 只读总结与 **新建项目双标签 busy** 已通过。项目 **6275** / `run_1789452602295343365`：并发写 409 `DOC_BUSY` 不新增第二 run；刷新后 `actions=[]`；PI 终态后租约自动解除。浏览器双标签截图见 `assets/2026-09-15-conversation-intent-dual-tab/screenshots/`。真实会话 `sess-p143-u9` 中的诊断消息与误启动产物只记录证据，不在未获确认时删除或回滚。`production_ready` 仍为 no（CI 三工作流 E2E / 前端抽检等其它 blocker）。
