Closes Definition of Done #5 from the cross-stack interop spec:
'Audit-branch fixes T1-T14 each have >= 1 hang-tier AND/OR
browser-tier scenario asserting their wire output. Gap matrix
committed at .../cross-stack-interop-test-gap-matrix.md'.
Maps each T# wire fix that landed in main (T8, T10-T14) to its
asserting interop scenario(s):
- T8 (CSD skip) -> I11 hang ✅, I14 browser ⏳
- T10 (mute endGroup) -> I3 hang ✅
- T11 (drop bestEffort) -> I9 hang ✅
- T12 (group seq h/s) -> I5 hang ✅
- T13 (decoder reset) -> I7 hang ✅ (in sister branch)
- T14 (GOAWAY) -> N/A in moq-lite-03 (IETF unit test only)
Notes the spec's 'T1-T14' is aspirational — only T8, T10-T14 are
concrete fix commits in main; T1-T7, T9, T15 never crystallised.
Documents two coverage holes: I13 (browser framesPerGroup=50 long
broadcast) and I14 (WebCodecs warmup x CSD-skip), both deferred
from Phase 4.C of the browser harness.
No code change.
