Two things about titles were wrong. Every chat spent a second completion on its name, including an agent chat whose opening words are already a title -- somebody starting one states an objective, not a topic. An agent chat now takes `fallback_title` from its first prompt and makes no request at all; an ordinary chat, which opens with a question whose *answer* is what makes a title worth asking for, is unchanged. And renaming existed only as the `/title` slash command, which set the heading and left the sidebar row showing the old name until the next reload -- a rename that looks half-applied is one people do twice. There are pencil buttons on the heading and on every sidebar row now, both PATCHing the route that was already there, and `update_chat` answers a rename with the out-of-band pair the `done` frame has always sent, so one response moves both. Only on a rename: sending it for every PATCH would overwrite the heading from an unrelated save. `/title` sets both spans itself, being a bare fetch rather than htmx. The dialog is the `data-prompt` mechanism the folder work added, which is why the heading keeps a button rather than becoming an inline field: it sits in a flex row beside the badges and the connection chip, and swapping it for a text box moves all of them.
