+## 2026-07-02 — 10:52 110 startup SSH control path metadata 自動修復
+
+**照主線修正的問題**：
+- 全主機 cold-start readback 顯示 110 唯一 BLOCKED 是 read-only SSH command path timeout：`SSH_110_BLOCKER remote_control_channel_unavailable`；node-exporter / runner pressure evidence 顯示 110 runner job count 為 0、load classifier 不是高負載，因此主線問題收斂為重啟後 control path metadata / session path 需能自動修復。
+- `scripts/reboot-recovery/awoooi-startup-110.sh` 新增 `repair_ssh_control_path_metadata`，在 Docker / Harbor / runner 啟動前先呼叫 `/usr/local/bin/repair-110-ssh-publickey-auth-local.sh --apply`，預設 target user `wooo`、`RELOAD_SSH=0`，只修復 `.ssh` / `authorized_keys` ownership / mode 與 `sshd -t` syntax guard。
+- 這條路徑不讀、不列印、不建立 key material；helper 缺失或修復失敗時記錄 warning 並繼續既有 startup recovery，避免 SSH guard 反過來阻斷 Docker / Harbor recovery。
+- `scripts/reboot-recovery/tests/test_cold_start_monitor_bounded_probes.py` 新增 contract，鎖定 SSH metadata repair 必須在 Docker 前執行、必須使用 local-only repair helper、預設不 reload SSH、不得包含 `cat authorized_keys` / `ssh-keygen` / `ssh-copy-id`。
+
+**驗證**：
+- `bash -n scripts/reboot-recovery/awoooi-startup-110.sh scripts/reboot-recovery/repair-110-ssh-publickey-auth-local.sh scripts/reboot-recovery/recover-110-control-path-and-harbor-local.sh`：通過。
+- `python3.11 -m pytest scripts/reboot-recovery/tests/test_cold_start_monitor_bounded_probes.py scripts/reboot-recovery/tests/test_recover_110_control_path_and_harbor_local.py -q`：`20 passed`。
+- `python3.11 -m pytest ops/runner/test_cd_controlled_runtime_profile.py -q`：`43 passed`。
+- `python3.11 ops/runner/guard-gitea-runner-pressure.py --root .`：`GITEA_RUNNER_PRESSURE_GUARD_OK workflow_files=12 scheduled_workflows=4 auto_branch_events_on_110=0 generic_runner_labels=0`。
+- `git diff --check`：通過。
+
+**邊界**：未使用 GitHub / `gh` / GitHub API；未讀 secret / token / `.env` / raw sessions / SQLite / auth；未重啟主機，未 restart Docker / Nginx / K3s / DB / firewall，未 workflow_dispatch，未恢復 generic runner。當前 110 live SSH command path 仍需等此版部署到 startup 後由本機 startup / console path 套用，不能把 source 修正宣稱成 runtime 已解。
+
+**下一步**：commit / push Gitea `main`，讀回 Gitea CD controlled-runtime；CD 成功後再重跑 cold-start scorecard，確認 110 command path 是否已恢復，若仍 blocked 則走 local console recovery package 驗證，不展開支線。
