Brings in, through the refreshed previous link, main's OER differential fuzzer (54e89b56) and its audit of the OER extension against both verifiers (860ead8c, documentation only), so this link is checked against current main. Co-Authored-By: Claude Opus 5.5 <[email protected]>

SPEC §5 registers the elementary video and audio bitstreams that distribution
chains carry, as sink-supplied capabilities:
wai.video.{av2,vvc,hevc,avc,vp9,evc,evc.baseline,avs3,lcevc} and
wai.audio.{aac,mpegh,avs3}. Each carries a licence class (royalty-free, or
flagged SEP-pool/proprietary), and no flagged codec can become a default.
- Every capability now has an explicit replicate class, and an "exact" class
is given only where a recorded basis supports it: a standard that requires
bit-exact decoder output, or a measured comparison. Elsewhere the class is
conservative, and the registry says what evidence would raise it.
wai.mesh.glb is not cross-decoder-exact, because a GLB can embed coded
textures and compressed geometry. wai.audio.scene answers "not known" until
its sources are known (is_cross_decoder_exact_with_sources).
- wai.video.lcevc is an enhancement layer, pinned to the ISO/IEC 23094-2
Annex B byte stream and carried as a companion bound to a base payload
(SPEC §7.1). Its list of base codecs is WAI's registration, not a limit
imposed by that standard.
- The companion rules are enforced: a WAI2 companion must be companion-only
and must bind to a base it applies to (an HDR descriptor to a video payload,
LCEVC to its registered bases), with negative tests. SPEC §7.1 lists the
envelopes this makes non-conforming.
- A companion-only fallback closes dispatch at step 5, not step 3, so decode
and inspect agree (SPEC §4).
- SPEC §8 states what a new registration does to earlier uses of its string,
and what a MINOR revision may enforce.
- research/media-codec-registry.md records the licence and replicate basis
for each entry.
