+- 工单：`56f6ca23-d242-4fab-88f3-81fed692e00d`
+- 邮箱批准：已批准。
+- 执行动作：`provision-approved-architecture`
+- 结果：`FAILED_BEFORE_MUTATION`
+- 服务器诊断：部署器尝试从旧 `fifth-domain` 历史仓库获取 `2739104088fa199fb8762e56a3a7cf285dc82f3f`，远端返回 `not our ref`。
+- 因果判断：批准资源和当前代码频道提交本身正确；现实部署器的 `ARCHITECTURE_PROVISION_REPO_URL` 仍指向历史仓库。失败发生在复制、安装和重启之前，AI 服务未改变。
+- 修正规则：部署器默认来源与环境示例统一改为 `https://guanghulab.com/code/bingshuo/guanghu-ice-heart.git`。不得为迎合旧部署器把当前补丁反向复制进历史仓库。
+- 后续条件：先通过受控固定动作更新京东部署器并读回来源；之后为原始不可变工程资源重新建单。原工程 SHA 不因部署器修复而伪造变化。
