 - 讀回 188 host hygiene：`awoooi-startup.service` 因 300 秒 timeout 失敗，卡在 ClawBot `docker compose build --no-cache`；但 live `clawbot` / `clawbot-redis` 容器已 healthy，證明舊 startup path 會把單一 rebuild 誤放大成整機 post-reboot failed。
 - 修正 `scripts/reboot-recovery/awoooi-startup.sh`：ClawBot startup 改成 bounded `docker compose up -d`，rebuild 預設 opt-in (`CLAWBOT_STARTUP_REBUILD_ALLOWED=0`) 且有 timeout；移除預設 `--no-cache` rebuild。
 - 修正 `scripts/reboot-recovery/awoooi-startup.service`：`TimeoutStartSec=600`，對齊 10 分鐘 SLO，但不允許單一服務 rebuild 佔滿整個恢復窗口。
+- 修正 `scripts/reboot-recovery/deploy-to-188.sh`：移除硬編碼 sudo credential 與 `sudo -S` 路徑；deploy helper 改為 passwordless sudo / explicit TTY sudo fail-closed，不保存、不讀取、不回顯密碼。
 - 補 `scripts/reboot-recovery/tests/test_188_host_hygiene_checklist.py`，鎖住 bounded / opt-in rebuild 與 600 秒 unit timeout。
