+- [ ] 正式 adapter 化 Jarvis graph 路径
+- [ ] 引入 runtime registry / factory
+- [ ] 减少 `if runtime == ...` 的散落逻辑
+- [ ] 保持 router / SSE 契约不破坏
+
+## H2 Continuity Envelope
+
+- [ ] 设计统一 `Conversation.agent_state` envelope
+- [ ] 加入 `active_runtime`
+- [ ] 加入 `runtime_state.hermes`
+- [ ] 保留 Jarvis product continuity
