A session could be created from the sidebar but never removed, so the chat surface accumulated every experiment anyone ever named. Each row now carries a small delete affordance that only names the key: the confirmation is the shell's, and it says the turn history goes with the session before calling the new route. On confirm the chat moves to the first remaining session — the stream's watcher follows the key — so nothing keeps streaming a session that no longer exists. The row had to stop being a single button, since a nested button is invalid HTML: the select button and the delete button now sit in a container that owns the hover and active surface.
