 ### 使用者影响
 
-升级到 Calcit 和 `@calcit/procs` **0.38.0** 后，请重新安装依赖、编译并刷新。文本输入、Run 输出、原 Map 存档和页面 HUD 继续适用。 应用操作和 Reel 控制解码后通过 `ResolvedOp` union 区分，已有 Reel 标签和存档结构保持兼容。
+升级到 Calcit 和 `@calcit/procs` **0.40.0** 后，请重新安装依赖、编译并刷新。文本输入、Run 输出、原 Map 存档和页面 HUD 继续适用。 应用操作和 Reel 控制通过 `ResolvedOp` union 区分。Reel 面板直接接收独立控制回调，原存档结构保持兼容。
 
-Reel 使用 `State<Op, Store>`。旧操作在入口解码，业务更新器接收具名操作。状态路径沿用 `CursorKey = Tag | String | Number`，已有 Map 或 Struct 存档仍在恢复时校验。恢复成功后才注册离页保存。

-正式依赖为 Respo **0.19.5**、Reel **0.10.0**、Markdown **0.8.2**、UI **0.15.2**、JS-FFI **0.2.13**，传递 Router **0.12.2**。

 ### Workflow
 
 Use `calcit.cirru` and `deps.cirru`; do not restore the retired `compact.cirru`
 or `package.cirru`. Generated `js-out/` is not committed.
 
-Use Node 24 and Yarn 4.18.0. Install Calcit 0.38.0 and Caps 0.1.1 separately
+Use Node 24 and Yarn 4.18.0. Install Calcit 0.40.0 and Caps 0.1.1 separately
 (the latter follows [the official Caps installation](https://github.com/calcit-lang/caps)); Corepack/Yarn does not install Caps. Strict dependency installation and the original type/test gates are retained.
 Browser and production acceptance remain separate from successful compilation.
