+## 2026-07-01 — 17:18 Gitea CD post-deploy smoke 依賴證據修正
+
+**照主線修正的問題**：
+- CD `#4270` 已成功完成 tests、build-and-deploy、ArgoCD sync、K8s rollout 與 production deploy readback，但 post-deploy browser smoke 回 `SMOKE_RESULT=⚠️`；log 顯示 `npx playwright` 下載孤立 CLI 後找不到 workspace 內的 `@playwright/test`。
+- `.gitea/workflows/cd.yaml` 的 E2E smoke script 改成 `set -euo pipefail`，`pnpm install` 失敗會直接失敗，不再被 `tail` pipe 吃掉；安裝後用 `pnpm --dir apps/web exec node -e "require.resolve('@playwright/test')"` 做明確依賴 readback。
+- Playwright 安裝與執行全面改用 workspace 依賴：`pnpm exec playwright install`、`pnpm exec playwright install-deps`、`pnpm exec playwright test`；禁止回到 `npx playwright` 造成假 smoke。
+- `ops/runner/test_cd_controlled_runtime_profile.py` 新增 guard，鎖住 post-deploy smoke 必須使用 workspace Playwright，避免 Gitea/CD 顯示綠燈但 browser smoke 沒有真跑。
+
+**邊界**：未讀 secret / token / `.env` / raw sessions / SQLite / auth；未使用 GitHub / `gh` / GitHub API；未重啟主機 / Docker / Nginx / K3s / DB / firewall；未 force push。
+
+**下一步**：跑本地 workflow guard 後推 Gitea main，讓下一個 CD 重新產生 post-deploy smoke 證據；production 目前已由 `#4270` 讀回 `fdbbe408c3` closure verified。
