Plan tracking: codex 无 TaskCreate/TaskUpdate/TodoWrite 任务板。进度清单用 update_plan({ explanation?, plan: [{ step, status }] }) 维护（整体提交步骤数组，status: pending | in_progress | completed），权威状态始终在 session 工件中；依赖/认领（addBlockedBy/owner）是工件字段，不是工具参数。

If required reading was not expanded by the host, or is no longer in context, Read it explicitly before execution.

<deferred_reading> Maestro Codify extension only — do not read these files for normal Impeccable work:

ui-codify.md — load when --codify starts
ui-codify-extract.md — load only when extraction starts
ui-codify-package.md — load only when packaging starts
ui-codify-knowhow.md — load only after the knowhow confirmation gate passes </deferred_reading>
