 ### `TodoItem`：一条待办项
 
-这是 `todo/write` 事件全量列表快照中的单元。它有意保持精简：一行 `content` 加一个三态 `status`（没有 id、优先级或 `activeForm`）；列表在每次写入时整体替换，因此条目无需稳定标识，而这三个状态值恰好对应 ACP 的 `PlanEntryStatus`，所以 UI 桥接层可以将待办列表一一映射为 ACP `plan`（并合成 ACP 额外要求的优先级）。见 [todo_write Agent Note（agent 决策记录）](../../.agents/notes/implemented/feature/2026-06-29-todo-write-tool.md)。
