Control messages
What each request got back, per draft. ok and err are both answers; ✗ is a request refused or left unanswered; a dash is a request our side did not complete. Times run from the request to its answer; each request waited up to 3,000 ms.

- Offers a track
- relay offered the track
Two publishers of one track
Two publishers announce the same namespace and publish the same tracks, one with identical payloads and one with payloads that differ by publisher. Partway through, the publisher serving the subscribers disconnects without notice. A fresh subscription, sent afterwards, shows whether the remaining publisher could still be reached.
| Publisher | Role | Announcement | Subscribed to | Ended by the relay |
|---|---|---|---|---|
| first publisher | standby The relay accepted it and never subscribed to it while a subscriber was waiting. | accepted, REQUEST_OK in 163 ms | — | — |
| second publisher disconnected | serving The relay accepted it and subscribed to it. | accepted, REQUEST_OK in 163 ms | differing payloads, identical payloads | — |
| Track | Objects | From | When the publisher left | Ended by |
|---|---|---|---|---|
| identical payloads | each object once 15 delivered | — | ended by the relay | PUBLISH_DONE 2 “track ended” |
| differing payloads | each object once 15 delivered | second publisher | ended by the relay | PUBLISH_DONE 2 “track ended” |
A fresh subscription after the publisher left: delivered, the relay subscribed to the first publisher, first object in 328 ms.
Ended or stalled a subscription when its publisher left, while the other publisher of the track was still accepted and reachable.

If something here is wrong, tell us — we keep what each result rests on, so a disputed one gets re-read rather than re-argued. We can also run this against endpoints that are not public.
