List Sessions

Sessions by last activity. The worker holds the conversation; the grant and the record stay Stormy's — uses_delegate_harness marks the harness lane.

surface asks for ONE ROOM (channel:view/taxes). A chat client opening a page needs the newest session on that surface and nothing else; without this it asked for a hundred and kept one, which cost the phone 284KB and 4256ms through the tunnel per page open (measured 2026-09-09). Omitting it is the old answer, unchanged.

transcript THEN SAVES THE SECOND ROUND TRIP. Once the payload was small, the whole cost of opening a chat was that it takes TWO sequential requests — find the room, then read it — and a phone on the local tunnel pays ~1.2s of latency for each, however few bytes come back. The newest room's turns ride along on the first answer, so the ordinary open is one request instead of two.

It is a FAST PATH, never a contract. The turns are attached to the FIRST row only, and a client that picks a different row simply reads that row's transcript in the request it would have made anyway — which is also what a client talking to a backend older than this parameter does.
