 `ctx.commands.register(definition)` registers one lowercase command name, description, optional unstructured-input hint, and abortable handler. A registered command is available to every composed command adapter; a plugin that is incompatible with a deployment does not register there. A plain-context registration is global. A command-producing plugin mounted beneath `agent.ctx` declares its own `commands` injection and creates an exact agent-scoped definition; it shadows a global definition with the same name. This child-injection shape preserves the agent scope without making the core agent loop depend on a UI service. Duplicate names within one layer fail during registration. Every disposer is the exact Cordis effect disposer, and registration or removal notifies every `commands/change` observer so live adapters can refresh discovery; observer failures are logged and cannot veto the registry mutation or starve later observers.
 
-`list(agent)` returns immutable, name-sorted descriptors after scoped shadowing. `find(agent, name)` returns the corresponding definition. `execute(agent, line, signal)` uses `parseCommand()` and runs only a known command, returning `undefined` for invalid syntax or unknown names. A resolved command's lifecycle is durably logged on the receiving agent's session as the log-only pair `command/run` (before the handler, with a minted `commandId`, the parser's structured `name`/`args` split, and the issuing `CommandSource`) and `command/done` (at settlement, with the outcome kind and verbatim text; a thrown or aborted handler settles as `kind: 'error'`). Admission misses log nothing. Lifecycle appends are serialized per session through `SessionStore.appendOutOfBand`, so the service requires a composed `sessions` service.
+`list(agent)` returns immutable, name-sorted descriptors after scoped shadowing. `find(agent, name)` returns the corresponding definition. `execute(agent, line, signal)` uses `parseCommand()` and runs only a known command, returning the settled `CommandExecution` (the normalized result plus the lifecycle pairing `commandId`) or `undefined` for invalid syntax or unknown names.

 `parseCommand()` recognizes a slash at byte zero, a lowercase name containing letters, digits, `_`, or `-`, and either end-of-input or whitespace. It returns every byte after the name as `rawInput`, including separator whitespace; consumers own their command-specific grammar and may normalize only what that grammar permits.

 `ctx.commands.register(definition)` 注册一个小写命令名称、描述、可选的非结构化输入提示，以及可中止的处理器。每个已注册命令都可供所有已组合的命令适配器使用；与某项部署不兼容的插件不会在此注册。普通上下文中的注册全局生效。在 `agent.ctx` 下挂载的命令生产插件会声明自身的 `commands` 注入，并创建精确限定到该 agent 的定义；该定义会遮蔽同名的全局定义。这种子级注入形态保留了 agent 作用域，同时不会让核心 agent loop 依赖 UI 服务。同一层中的名称重复会在注册时失败。每个 disposer 都是 Cordis effect 返回的确切 disposer；注册或移除命令时，系统会通知每个 `commands/change` 观察者，使实时适配器能够刷新发现结果。观察者失败会写入日志，既不能否决注册表变更，也不能阻止后续观察者运行。

 `parseCommand()` 识别位于字节零位置的斜杠、由小写字母、数字、`_` 或 `-` 构成的名称，以及名称后紧接输入末尾或空白的形式。它将名称后的每个字节作为 `rawInput` 返回，其中包括分隔空白；消费方拥有各命令专用的语法，只能执行该语法允许的规范化。
