 ## BUG-129 | staging trusted-main checkout 无界 fetch 导致自动部署长期占用 mutation queue

 - 触发条件：Gitea runner 在空仓库中抓取 reviewed `main` 和目标 SHA 时传输长时间停滞；底层远端/网络原因未闭环。checkout step 没有命令级 timeout/retry，只依赖 30 分钟 job 总超时。
 - 根因：已确认的控制面根因是发布控制器对镜像拉取有 bounded retry，却对 trusted-main Git fetch 采用无界单次调用；无论底层传输为何停滞，该调用都会长期占用 `staging-mutation` queue，并推迟后续受控重试。底层 Git 传输停滞原因保持 blocked，不作推断。
 - 修复：Gitea deploy 与 migration 的 trusted-main fetch 改为最多 3 次、每次 120 秒的 bounded retry，重试间隔递增；耗尽后明确 fail closed。仍只 checkout `origin/main`，仍要求目标 SHA 是 reviewed main ancestor，不改变 exact-SHA artifact、forward-only 或 manual rollback 边界。
-- 验证：待本地 workflow contract、Gitea PR quality gate、原 run `1474` 终止以及修复后 exact-SHA staging deploy 完成；未完成前不得标记 resolved。
+- 验证：原 run `1474` 最终成功部署 `02cc483b7c303e6cc0f26fb31462c50adb007f12`，公网 health、主机 state 与 `main/staging` 精确一致，5 个容器 restart count 均为 0；本地 staging workflow contracts 31/31、修改后 YAML 解析、mandatory pre-work 和 diff 检查通过；Gitea PR quality gate run `1475` 成功。修复后 exact-SHA staging 控制面部署仍按正常发布流程单独核对，不将原 run 的自行恢复冒充为 bounded retry 已在真实故障中触发。
 - 防复发：所有 release-controller 网络调用必须同时具备命令级上限和失败闭合；不得仅依赖 job 总 timeout。回归测试必须同时覆盖 deploy 和 migration 的 attempt 数、单次 timeout、最终错误和 ancestry check。

 Prevention: store `STAGING_SSH_PRIVATE_KEY` only as one unwrapped base64 line; workflows decode it into a mode-`0600` temporary key, validate it with `ssh-keygen`, and delete the temporary directory on every exit. Contract tests must reject direct multiline `SSH_PRIVATE_KEY` injection or `printf` of a decoded secret variable. A leaked staging key must be rotated and revoked before any rerun; production keys remain a separate boundary and were not involved in this incident.

 After exact-SHA staging gate `1473` succeeded, automatic deploy `1474` stopped making log progress for an extended period in the empty-repository `git fetch --no-tags origin main "$DEPLOY_SHA"` step before any SSH or staging mutation. Public and state SHAs remained on the previous healthy release during the stall. The fetch later recovered and the 18-minute run successfully deployed the exact SHA, but the checkout had no command-level bound; without recovery, the 30-minute job timeout was the only escape and the shared mutation queue would remain occupied. The underlying Git transport stall is not proven.
