joule-moq-ingest: a grant whose ai attribute is not a model digest is grant_invalid (live-rooms §4.4) ...

The rooms corpus gained grant_ai_malformed with the synthesis slice; the gateway's own grant
reader now refuses it as wai-rs does.

synthesis corpus: a reconstruction whose samples make both derivations' roundings decide ...

The reconstruction cleared the photo's low three bits, so every pair of samples summed to
an even number and the upscale's rounding never decided a sample: a falsification that
dropped it went uncaught. It now quantises to multiples of 3.

synthesis, live rooms: let-chains where clippy asks; wai-live-web reads a chat's origin ...

wai-live-web's decoded view of a chat carries its stated origin and model, and its chat
payload states none, as before.

wai.media.synthesis: registry entry and document kinds, SPEC §5, CHANGELOG, CI step ...

The registry lists the record wai.media.synthesis and its six document kinds; the export
is regenerated (registry export --check is up to date). SPEC §5 says what the record is.
The conformance workflow runs the module's unit tests, tests/synthesis.rs and
synthesis_verify.py, and fires on an edit of the extension, whose tables the tests read.

synthesis_verify.py: the synthesis corpus's second implementation ...

Written from extensions/synthesis.md: strict JSON and JCS of its own, the pinned
derivations in its own arithmetic, the digital source type and the C2PA statement written
from §5 and §6, rooms through live_rooms_verify.py, Ed25519 and BLAKE3 through the
claim-conformance helpers. It agrees with wai-rs on every vector and refuses every mutated
copy of the corpus.

wai.media.synthesis: origin claims for every kind of media, two marking layers, reviews and labels ...

extensions/synthesis.md: the origin claim of an object, a group or a track (captured,
reconstructed, assistive, synthesized; the class rises along a chain of derivations and
never falls), its IPTC digital source type and C2PA statement as functions of the claim,
two pinned integer derivations whose recomputation proves an assistive claim, the marking
and detection records of the second layer and their agreement with the first, AI
participants' tracks, reviews a player presents only on a decode path of the review's
tier, and a player's signed label log with the EU icons pinned by digest. The wai-rs
module (feature `synthesis`), its vectors generator and the corpus.

live rooms: AI participants are marked in their grant, and chat and reactions state their origin ...

live-events §4.4 and §4.5: a chat and a reaction may state an origin after their last
field (1 human, 2 machine, 3 machine-reviewed, with the model's digest for 2 and 3), as a
caption does. live-rooms §4.4: the grant attribute `ai` names the model that acts for an AI
participant; §9.2 step 6 refuses its chat, reaction or caption that does not state origin 2
or 3 with that model (`ai_unmarked`), and a relay does not forward one. Both corpora gain
vectors (additions only); both second implementations read the new fields.
