+# module-runtime 独立模块 package 占位说明
+
+日期：`2026-04-20`
+
+## 1. package 职责
+
+`module-runtime` 是运行时状态基座模块 package，后续负责：
+
+1. `runtime_snapshot`、`runtime_setting` 等主状态模型
+2. profile dashboard、browse history、save archive 相关读写模型
+3. 运行时状态归一化与兼容聚合快照策略
+4. 与 `apps/api-server` 的 runtime facade 对接
+5. 与 `apps/spacetime-module` 的运行时表与 view 聚合对接
+
+## 2. 当前阶段说明
+
+当前提交仅完成目录占位，不提前进入表结构、projection 与接口实现。
+
+后续与本 package 直接相关的任务包括：
+
+1. 设计 `runtime_snapshot`、`runtime_setting`
+2. 设计 `profile_dashboard_state`、`profile_wallet_ledger`
+3. 设计 `profile_played_world`、`profile_save_archive`、`user_browse_history`
+4. 落地存档、设置、资料页兼容接口
+
+## 3. 边界约束
+
+1. `module-runtime` 负责运行时状态真相与模块级 facade 编排，不把主状态继续留在旧式大 JSON repository 中。
+2. 兼容快照可以作为聚合产物保留，但不能再次成为唯一真相。
+3. 前端兼容接口由 `apps/api-server` 暴露，状态表与 view 最终由 `apps/spacetime-module` 聚合。
