+## 2026-06-28 — 10:45 controlled cd-lane drain source verifier 補齊
+
+**時間與來源**：
+- 2026-06-28 10:33-10:45 Asia/Taipei。
+- 來源：110 live `awoooi-cd-lane-drain.service` readback、feature branch `codex/source-controlled-cd-lane-drain-20260628`。
+
+**完成內容**：
+- `scripts/reboot-recovery/awoooi-startup-110.sh` 新增 drain lane verifier：當 `/home/wooo/awoooi-cd-lane-drain` 符合 `capacity=1`、AWOOOI 專用 labels、binary 為 ELF、systemd active 時，保留 drain lane 並只 fail-close regular `awoooi-cd-lane.service`。
+- `full-stack-cold-start-check.sh`、`post-start-quick-check.sh`、`p3-controlled-release-gate.sh` 新增 `CD_LANE_DRAIN_CONTROLLED` 與 `CD_LANE_GUARDRAILS_OK` readback，接受 regular controlled/failclosed 或 drain controlled-open 任一通過。
+- legacy direct/Gitea runner fail-closed、direct runner process count、runner binary stub 檢查維持原樣；未恢復泛用 runner。
+
+**本地與 live 驗證結果**：
+- `bash -n scripts/reboot-recovery/awoooi-startup-110.sh scripts/reboot-recovery/full-stack-cold-start-check.sh scripts/reboot-recovery/post-start-quick-check.sh scripts/reboot-recovery/p3-controlled-release-gate.sh`：通過。
+- `git diff --check`：通過。
+- 110 live readback：`CD_LANE_DRAIN_CONTROLLED mode=controlled_open load=loaded unitfile=enabled active=active capacity=1 labels=1 binary_elf=1 ok=1`、`CD_LANE_GUARDRAILS_OK 1`。
+
+**仍維持**：
+- regular `awoooi-cd-lane.service` masked/inactive；legacy direct runner units fail-closed。
+- 不讀 `.runner`、SQLite、raw session、auth、`.env`；只驗 systemd、capacity/labels 與 binary kind。
