 - 是否需要显示“预计剩余时间”。如果需要，建议第一版只显示粗略区间，不做精确倒计时，避免误导。
 
+完成记录：
+
+- 完成日期：2026-07-03
+- 相关改动：
+  - 任务详情页新增运行时长、最近进度相对时间、热点 / 评论 / 报告数量和默认规模耗时提示。
+  - `GET /api/tasks/{task_id}` 新增运行秒数、最近进度秒数、中文时长文案、长时间无进度布尔值和 10 分钟阈值。
+  - running 任务超过 10 分钟无进度更新时，页面展示“可能仍在等待外部接口或 AI 响应”的提示。
+  - 兼容 SQLite 读出的无时区 datetime，避免运行时长计算因 naive / aware datetime 混用报错。
+- 验证命令：
+  - `docker cp app/. hot-comments-tool-app-1:/app/app/`
+  - `docker cp tests/. hot-comments-tool-app-1:/app/tests/`
+  - `docker exec hot-comments-tool-app-1 sh -lc 'python -m pytest /app/tests/integration/test_routes.py::test_running_task_detail_page_shows_stage_runtime_and_stale_progress_warning /app/tests/integration/test_routes.py::test_task_api_includes_runtime_and_stale_progress_fields -q'`
+  - `docker exec hot-comments-tool-app-1 sh -lc 'python -m pytest /app/tests/integration/test_routes.py -q'`
+- 验证结果：
+  - WO-13 聚焦测试：`2 passed, 1 warning`
+  - 路由集成测试：`21 passed, 1 warning`
+- 验收结论：
+  - 用户无需打开日志即可看到任务当前阶段、运行时长、最近进度、热点 / 评论 / 报告数量和长时间无更新提示。
+  - 本轮不显示精确预计剩余时间，只显示非承诺式耗时说明，避免误导。
+- 遗留问题：
+  - 轮询接口失败时的前端可见同步失败提示仍归入 WO-19。
+  - 当前仍通过运行容器执行测试，本机 `.venv` 依赖未恢复。
