+## 2026-06-28 — 09:16 direct runner source guard 實作收斂
+
+**背景**：09:00 前的 live hotfix 已把 110 上 direct / Gitea runner 全部 mask，但 `awoooi-startup-110.sh`、cold-start 與 P3 release gate 還沒有把 `awoooi-direct-runner-open.service` 這條 transient direct runner 路徑納入 source-level guard。
+
+**完成內容**：
+- `scripts/reboot-recovery/awoooi-startup-110.sh` 新增 `RUNNER_FAIL_CLOSED_SERVICES` 與 `RUNNER_FAIL_CLOSED_BINARY_PATHS`，預設未同時具備 `AWOOOI_START_GITEA_RUNNER_ON_BOOT=1` 與 `/run/awoooi-runner-host-enabled` 時，會強制 kill / disable / mask direct runner 與 Gitea runner units，並把 live runner ELF quarantine 成 163-byte fail-closed stub。
+- `scripts/reboot-recovery/full-stack-cold-start-check.sh` 新增 110 runner fail-closed readback：direct / Gitea units 必須 `load=masked unitfile=masked active=inactive`，direct runner process count 必須 `0`，runner binary 不得是 ELF。
+- `scripts/reboot-recovery/post-start-quick-check.sh` 新增 `110 runner fail-closed guard` section，並以 `HOST_WEB_BUILD_PRESSURE_ATTEMPTS=1` 讀回 pressure gate。
+- `scripts/reboot-recovery/p3-controlled-release-gate.sh` 將 direct runner fail-closed 狀態納入 `BAD_RUNNER_GUARDRAILS`，避免 P3 release gate 只看 `actions.runner.*` 而漏掉 transient direct runner。
+- Live `/usr/local/bin/awoooi-startup-110.sh` 已更新並加 immutable；讀回 `LIVE_STARTUP_DIRECT_UNIT=1`、`LIVE_STARTUP_GUARD_FUNC=2`、`LIVE_STARTUP_DEFAULT=failclosed`。
+
+**驗證結果**：
+- 本地：`bash -n` 通過 `awoooi-startup-110.sh`、`full-stack-cold-start-check.sh`、`post-start-quick-check.sh`、`p3-controlled-release-gate.sh`；`git diff --check` 通過；direct runner source invariant 通過。
+- quick-check runner-only：`POST_START_QUICK_CHECK PASS=13 WARN=0 BLOCKED=0`、`RESULT=GREEN`；六個 runner/direct units 全部 masked / inactive、runner process `0`、四條 binary path 皆為 shell stub、pressure gate `RUNNER_PRESSURE_GATE_RC 0`。
+- cold-start 單次讀回：runner guard OK；整體仍 `PASS=90 WARN=1 BLOCKED=1`、`Result: BLOCKED`，blocker 是 `188 momo daily sales data stale beyond 3 days`，不是 runner。
+- P3 release gate：runner/CD guardrails 顯示 `BAD_RUNNER_GUARDRAILS 0`；整體仍 `HOLD_P3_RELEASE`，blockers 包含 cold-start、188 backup stale、188 litellm not running。
+
+**邊界**：本段沒有重啟 Docker / Nginx / firewall / K3s / DB，沒有讀 raw sessions / SQLite / auth / `.env` / runner token，也沒有恢復 110 runner。
+
 ## 2026-06-28 — 08:45 110 runner 壓力事故 source / live fail-closed 收斂
 
 **背景**：統帥全面授權打開非事故級 gate，但 110 Gitea runner 反覆拉起 StockPlatform headless Chrome smoke，已造成 production host CPU / CI 壓力事故；runner 未搬遷 / 限流前不得直接重開。
