 When the Host reports that no adapter serves the session's route (`session.models.routable`), this plugin raises a composer block through `ctx.conversation.blocks` and the input goes inert with this plugin's own copy; recovering clears it without a reload. It follows `routable` and nothing else: a `null` — before the first load, or after one failed — never blocks, or a slow Host would lock a working composer, and catalog membership never blocks either, because a route serving a model it stopped advertising is missing from the groups yet perfectly usable. The trigger's own `Select model` fallback still covers that case, which is display, not a gate.
 
-Directories are per-session, resolved lazily through `ctx.models.directoryFor(sessionId)`, and disposed with the session scope. Addressed subagent sessions expose neither entry, and their directory rejects loads, selections, and reconnect refreshes, because ordinary Agent-bound model RPCs would activate persisted child history outside the direct-parent continuation seam.

 当宿主报告没有适配器服务该会话的路由（`session.models.routable`）时，本插件经 `ctx.conversation.blocks` 注册一个 composer 阻塞块，输入框随之停用并显示本插件自己的文案；恢复后无需重新加载即自动清除。它只跟随 `routable`：`null`（首次加载之前，或加载失败之后）绝不阻断，否则一个慢的宿主就会锁死一个本来可用的 composer；目录成员关系同样不阻断，因为一条仍在服务、只是不再公布该模型的路由不在分组里，却完全可用。触发器自己的 `Select model` 回退仍然覆盖那种情形——那是显示，不是闸门。
 
-目录按会话惰性解析（`ctx.models.directoryFor(sessionId)`），随会话作用域一并释放。已寻址 subagent 会话不公开任一入口，其目录会拒绝加载、选择与重新连接刷新，因为绑定到 agent（智能体）的普通模型 RPC 会在直接 parent 继续执行 seam 之外激活持久化 child 历史。
