+## 2026-05-31｜Web probe health endpoint 收斂 rollout Smoke 警告
+
+**背景**：
+
+- Work Items 稽核鏈 production 驗證後，`59b4943b` post-deploy 雖然成功，但 CI/CD summary 顯示 `Smoke=⚠️`。
+- 追 K8s events 後確認 rollout 期間 `awoooi-web` 兩個 pod 各重啟 2 次，曾出現 readiness / startup / liveness probe timeout，瀏覽器短暫命中 `502 Bad Gateway`；rollout settled 後頁面恢復。
+- live deployment 的 web probes 打 `/`，而 `/` 會走 Next middleware 與 locale redirect / app shell，這不是最小健康檢查面。
+
+**本次調整**：
+
+- 新增 `apps/web/src/app/api/health/route.ts`：
+  - 回傳 `{"status":"ok","service":"awoooi-web"}`。
+  - 不讀 production API、不碰資料庫、不經 localized app shell。
+- `k8s/awoooi-prod/05-deployment-web.yaml`：
+  - `livenessProbe` / `readinessProbe` / `startupProbe` 全部改打 `/api/health`。
+  - 保留原本 timeout / threshold，先降低 probe surface，不直接放寬重啟條件。
+
+**驗證**：
+
+```text
+python3 -m json.tool apps/web/messages/zh-TW.json / en.json -> pass
+git diff --check -> pass
+pnpm --dir apps/web exec tsc --noEmit --tsBuildInfoFile /tmp/awoooi-web-health-probe-20260531.tsbuildinfo -> pass
+python3 scripts/security/security-mirror-progress-guard.py -> SECURITY_MIRROR_PROGRESS_GUARD_OK
+kubectl kustomize k8s/awoooi-prod:
+  awoooi-web liveness/readiness/startup path=/api/health
+kubectl kustomize k8s/awoooi-prod | kubectl apply --dry-run=server -f - -> pass
+NEXT_PUBLIC_API_URL=https://awoooi.wooo.work pnpm --dir apps/web run build -> pass
+local production server:
+  GET http://127.0.0.1:3107/api/health -> 200 {"status":"ok","service":"awoooi-web"}
+  GET http://127.0.0.1:3107/ -> 307 /zh-TW
+```
+
+**目前整體進度（pre-deploy）**：
+
+- Web rollout / Smoke 穩定性：約 82%；已完成 probe surface 修正，待 Gitea deploy 後驗證 restartCount 是否不再增加。
+- 前端 AI 自動化管理介面同步：約 89%；Work Items 已 production 驗證，probe 修正避免下一輪 UI rollout 造成短暫 502。
+- 整體 AI 自動化飛輪：約 74%；本輪是部署穩定性收斂，不改 24h auto-repair claim。
+- 24h 完整 AI Agent 自動修復 production claim：0%；仍不可宣稱全自動修復閉環。
