wai.live.message and wai.live.call registered as records, their seven magics as
wire identifiers, and the export regenerated. SPEC §5 says what each is;
confidentiality §5.5 names the conversation's commit rule. wai-conformance runs
tests/live_messaging.rs and live_messaging_verify.py; joule-moq-web's job
requires the messaging and call scenarios to pass. joule-moq-room's README and
example configuration describe [messaging] and [call].
