extensions/loc-carriage.md maps an envelope whose payload is one WebCodecs
chunk (an Opus packet, an AVC or HEVC access unit in Annex B, an ADTS
frame) onto one object of a track of packaging loc (draft-ietf-moq-loc-04):
the payload as the LOC Payload, the manifest as the Immutable Property
WAI_MANIFEST (0x3A61), the receipt commitment as WAI_RECEIPT. A reader
rebuilds the envelope byte for byte and checks the receipt against it,
refusing with the extension's codes. joule-moq's loc module writes and
reads; its example writes the corpus and tests/loc_vectors.rs checks it;
loc_verify.py is the second implementation. WAI_MANIFEST is registered as
a wire identifier; moq-streaming-format §6 points to the carriage.
