+# 小湖灯连续性守卫 · 代码频道策略
+
+本目录保存小湖灯本地协调 Agent 已采用的可公开恢复策略：
+
+- 代码频道 Web 根只有 `https://guanghulab.com/code/`。
+- 当前只允许 REPO-012 与 REPO-014。
+- HTTPS、`.git` 和 `repo://` 先归一化为同一个仓库身份。
+- 实际写租约必须是 `repo://.../<repository>#<exact-branch>`。
+- 旧 `/fifth-domain/`、其他主机、未登记仓库和含凭证 URL 失败关闭。
+
+本模块是策略事实源和回归样例，不代表 JZAO 上的本地协调运行时已经部署到服务器。运行时
+升级、仓库发布和服务器部署仍分别举证。
+
