Fresh stdio sessions use the process launch directory as `session.header.cwd` and mint one combined `main-session-<uuid>` agent/session id, so durable restarts cannot collide. The UI's `main` text is a display label, not a second routing id; the UI binds to that fresh-id namespace, or to the exact `resumeSessionId` for a resumed run, and never selects unrelated registry roots. Resumed sessions keep the cwd stored in the persisted session header.
Fresh stdio sessions use the process launch directory as `session.header.cwd` and mint one combined `main-session-<uuid>` agent/session id, so durable restarts cannot collide. The app passes that exact opaque id to both its config-created agent and UI; the UI's `main` text is only a display label and never selects another registry root by prefix or insertion order. A resumed run binds both components to the exact `resumeSessionId` and keeps the cwd stored in the persisted session header.
