Media delivery
One publisher and two subscribers, to see whether an object published through this endpoint reaches a client that asked for it.
The subscription routed to the publisher could not be read. The endpoint broke a rule of the draft: a request must not use a Request ID at or above the maximum the receiver granted.
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.

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.
