Chat

Tail chat-session events (SSE)

Server-Sent Events stream of Vercel AI SDK v6 envelopes for the session. Response is text/event-stream — stream it, don’t buffer.

Use ?since= (or the Last-Event-Id header) in two cases:

First connection for a turn just enqueued via POST .../messages — pass the since_cursor from that POST response so the tail starts strictly after the previous turn’s terminal envelopes.
Reconnect of an already-tailing stream — pass the last event id you received so playback resumes at the right spot.

Add ?for_message=<user_message_id> (from the POST response) to pin the tail to the single turn that answers that message. Without it the tail attaches to the first turn boundary after since, which can be a sibling turn’s when several messages are queued behind one running turn.
