Stream Agent Checkout Messages
Server-sent events for one checkout: message.upsert carries a message, run.updated a run update, and each event’s id is the cursor to resume from. Resume with last-event-id or after; omit both to stream from the start.
The checkout is read before the stream opens, so an unknown or inaccessible one is reported as a normal error status rather than an empty stream.
A resume cursor that is stale, or that belongs to another checkout, is the one failure that cannot be: only the stream request validates it, and the event stream has already begun by the time Universal Checkout rejects it, so the stream closes instead. Treat an unexpected close as a resynchronisation signal — re-read the message history and reconnect from the cursor it reports, not from the rejected one.
