 - 生成改动文档同步计划：按变更文件自动提示需要同步的 README、API、AGENTS、docs、Obsidian、skill 和 ktWorkflow 入口。
 - 生成多仓库提交/推送计划：按仓库分组、建议提交信息、列出提交和推送前检查。
 - 生成远程只读健康检查和数据库同步安全向导：覆盖飞牛 NAS 服务探测、GTID、`.kt-workspace/db-sync` 转储、备份库和行数校验。
+- 生成或执行部署观测：把 Jenkins build、commit、K8s Deployment、Pod、`/health/runtime` 和任务 smoke 汇总成 `.kt-workspace/test-artifacts/deploy-observation` 下的运行态证据。
 - 生成专项组件工作流：KtTable、BlogArgon、AdminAuth、QQBot、FF14Plugin、NapCatLogin、SystemLog、Knife4jSwagger、FnosK8s 的防踩坑清单和验证点。
 - 生成验证进程清理计划：按项目路径和端口给出 PowerShell 检查命令，不直接杀进程。
 - 清理历史产物：统一治理 `.kt-workspace` 下的测试/验证产物，按目录最近修改时间只保留最近 3 轮，模板目录永久保留；CLI 默认 dry-run，真实清理必须显式传 `--execute`。

 - 要收尾时调用 `kt_finish_task`，默认只生成计划和 review；需要执行验证时显式传 `runValidation=true`。
 - 大方向结束前调用 `kt_workstream_closeout` 或 `pnpm run workstream-closeout`；必须分别传入 `--review` 的 KT 全局审查证据和 `--superpowers-review` 的 Superpowers code review 证据；如果识别到测试流、卡点、误报、清理、部署观测或命令模板，要先升级对应 ktWorkflow 规则再报告完成。
 - 文件改动完成并验证后调用 `kt_global_code_review`，或运行 `pnpm run global-review`；它只读扫描，不删除文件、不提交代码。`findings` 先判定真实风险或工具误报，真实风险修业务代码，误报修 `mcp/ktWorkflow/src/tools/review.ts` 并复跑。
+- QQBot NapCat 登录 review 会检查验证码 pending、Docker 日志窗口、API Pod 读取超时，以及 `needNewDevice/jumpUrl` 是否被保留为 `deviceVerifyUrl` pending 状态。
 - 代码或配置改动后调用 `kt_change_doc_sync`，把需要同步的 README/API/AGENTS/docs/Obsidian/skill/ktWorkflow 入口补齐；无需同步时把原因写进收尾证据。
 - 报告非平凡任务完成前调用 `kt_workflow_loop_audit`，确认测试证据、文档同步、历史清理最终 `deleted=0`、问题固化、ktWorkflow 升级、KT 全局 review 和 Superpowers code review 都过门；清理证据必须显式传入，不能依赖缺省值。
 - 要提交或推送时先调用 `kt_commit_plan` / `kt_push_plan`，按仓库分组确认范围。
 - 要测真实业务链路时调用 `kt_business_test_plan`，选择 `admin-login`、`qqbot-auto-reply`、`qqbot-login-sse`、`fflogs-command`、`system-log-visualization` 等 flow。
 - 遇到同一命令或同一远程步骤重复卡住时调用 `kt_blocker_resolution`；第二次仍失败时先写入 `TASKS.md` 或补成脚本，再继续。
 - 远程服务排查先调用 `kt_remote_health_check`，默认只生成只读命令；需要执行时显式传 `execute=true`。

 - 数据库同步前调用 `kt_db_sync_plan`，先确认源库、目标库、`.kt-workspace/db-sync` 转储目录、带时间戳的备份库和校验点。
 - 改 KtTable、BlogArgon、AdminAuth、QQBot、FF14Plugin、NapCatLogin、SystemLog、Knife4jSwagger、FnosK8s 前调用 `kt_component_workflow`，先看专项禁区。
 - 不确定任务边界时调用 `kt_guardrails`，先拿到“能做什么、不能做什么、怎么验证”。
