 当前仓库现状说明：
 
-- 当前实现仍以 `single_file_content` 作为主要真实产物形态
-- 结构性代码任务尚未默认落成 `project_folder`
-- 这属于当前实现缺口，不应被视为最终统一协议目标
+- 结构性代码角色（如 `backend` / `frontend` / `coder` / `engineer` / `fullstack`）现在会优先产出 `project_folder`
+- 普通摘要/兼容型产物仍可能是 `single_file_content`
+- `project_folder` 当前已经支持 `manifest`、`archive.zip`、`files/{path}` 读取
+- 更完整的 revision / conflict 协议仍属于后续增强项
