Transaction Science 3b8dadc058 live-contribution: the extension text, its independent verifier, and the reference tools' interop ...

wai/extensions/live-contribution.md profiles SRT and RIST onto a room's tracks
through the ingest gateway: the one-time session resource, the listener's
checks and codes, the gateway calling, RIST's port, CNAME and PSK; the
transports as the gateway runs them; the transport stream onto the tracks;
and the link record WCL1, its account, parts and chain, how a part and a
series are verified, the size bound, the refusals, and the RIST texts' patent
notices.

live-conformance/live_contribution_verify.py is written from that text alone,
standard library only, with mutation runs and dropped-check runs. The corpus
gains vectors that isolate each check the verifier found uncovered.

Interop with the reference tools, run locally as test peers (ignored unless
named by environment variables): their SRT caller and listener and RIST sender
and receiver of both profiles against joule-contrib, and their SRT caller and
RIST sender into the gateway with an encoder's H.264, HEVC and AAC, through
lossy paths. Two fixes they found: an SRT recovery margin is held to the
window, and no part is cut before the first sequence number resolves.
