+## 仓库回退配置模板不能被读取通道私有化锁定
+
+- 现象：Windows 上 `apps/ai-game-creator-shell/game-creator.config.json` 莫名其妙被"加锁"（DACL 被剥成只剩一个陌生 SID，连 `Get-Acl` 都 unauthorized），开发 agent 和其他用户无法修改，cargo 也因 `include_str!` 读不到文件而不能编译；手动解锁后过一段时间又被锁。
+- 原因：无 AppHandle 的开发 CLI（`llm-status`、`agent-run`、`agc:test:chat` 等）经 `game_creator_config_paths()` 从 CWD / `current_exe` 向上回溯 8 级探测到 worktree 里的 git 跟踪模板后，读取走了为 AppData 私密凭据设计的私有通道 `open_project_private_regular_file` → `prepare_game_creator_private_path_for_read`；该函数名为 "for read"，在 Windows 上却无条件收紧目标 DACL 为"仅当前进程用户、禁止继承"。沙箱 agent 是其 checkout 文件的 owner，校验通过后被静默私有化，其他账号全部 Access Denied。
+- 处理：配置读取按路径归属分流——`read_game_creator_config_file` 只对位于 `game_creator_runtime_config_dir()`（AppData 托管目录）内的真实凭据走私有加固读取；仓库旁边的回退模板 / local 覆盖一律走 `open_project_snapshot_regular_file` 非变异快照通道，读取绝不修改 owner / DACL。这与 `open_project_private_regular_file` 注释中"非用户明确选择的文件用 snapshot 读"的既有原则一致。
+- 教训：任何名为"读前准备"的函数若附带权限收紧副作用，都必须按路径是否属于本进程托管范围设白名单；共享仓库文件、git 跟踪文件永远不在加固范围内。排查"文件莫名被锁"时优先查 DACL owner 是哪位 SID，再倒推哪个进程以该身份运行过。
+- 验证：`tests::configuration::fallback_template_read_stays_on_snapshot_channel_outside_runtime_dir` 与 `runtime_config_read_stays_on_private_channel_inside_runtime_dir` 锁定两条通道的分流；`node scripts/check-config.mjs` 通过。
