 - Plan mode guides rather than enforces; deployments needing a hard boundary must combine independent sandbox and approval controls.
 - A pending selection made while idle is lost if the process exits before the next boundary, so the UI must reapply it.
 - Forked agents inherit logged plan state, while newly spawned agents begin inactive; there is no creation-time plan option.
-- The `exit_plan_mode` review arc has one assembled-application snapshot, the Web `plan-review` e2e lane (submit → decision card → approved flip). The rejected-feedback and dismissed branches are covered by package tests only, and the TUI keyless scenarios exercise only `/plan` entry and `/plan off` exit.
 - Only the Web UI renders the `plan-review` intent; the TUI presents the review through its generic question flow, which is answerable but does not read as a plan gate.

 - Plan mode 只进行引导，而不强制执行；需要硬边界的部署必须组合独立的沙箱与批准控制。
 - 如果进程在下一个边界之前退出，空闲时作出的待生效选择会丢失，因此 UI 必须重新应用它。
 - Fork 的 agent 会继承已记录的 plan 状态，新 spawn 的 agent 则从未激活状态开始；不存在创建时 plan 选项。
-- `exit_plan_mode` 评审弧有一个组装应用快照，即 Web `plan-review` e2e 通道（提交 → 决定卡片 → 已批准切换）。已拒绝反馈与放弃审阅两个分支仅由包测试覆盖，TUI 无密钥场景只演练 `/plan` 进入和 `/plan off` 退出。
 - 只有 Web UI 渲染 `plan-review` 意图；TUI 通过其通用问题流程呈现该评审，可以回答，但读起来不像一个计划关口。
