nx_media_census.nx source

1// nx_media_census.nx -- the NISHI TEAM REVIEW of the whole video+audio+codec+room subsystem. 2// ONE honest, MEASURED, per-feature map (never a rolled-up binary scorecard -- that is the exact 3// wave the no-overclaim law forbids). Every axis carries its status + whether it is MEASURED + the 4// provenance gate that measured it. Categories: EXCEEDS / PARITY / BEHIND / WIRING-GAP / UNMEASURED 5// / MISSING. The structural ANTI-WAVE guarantee: grade() REFUSES to certify EXCEEDS for any axis 6// that is not measured -> a fabricated "exceed" is downgraded to UNMEASURED and the liar-kill proves 7// the guard fires. So this census cannot launder an unmeasured claim into a win. 8// 9// Provenance gates (all re-baselined GREEN this session): nx_codec_exceed_gate, nx_connect_room_exceed, 10// nx_room_resilience, nx_room_sfu, nx_room_fec, nx_room_jitterbuf, nx_room_qoe, nx_hevc_dec, nx_h264_*. 11// main() is the SELF-VALIDATING GATE.
