1// nx_codec_exceed_gate.nx -- SOVEREIGN organ-graded EXCEED census for the patent-free codec arc, vs 2// ffmpeg/x264, AV1, AV2. Embodies the doctrine "S-class exceed = MEASURED, multi-axis, organ-graded, 3// NEVER self-scored": every grade is computed by RULE from evidence, and the rules are proven with 4// NEGATIVE CONTROLS so the census cannot be gamed: 5// * patent-freedom is graded EXCEEDS only when the tool ledger has ZERO active-patent tools (a CABAC 6// in the ledger MUST drop it to BEHIND -- T4 proves it). 7// * the COMPRESSION axis is graded from a REAL head-to-head vs the STRONGEST named reference (x264, 8// H.264 intra): it reports BEHIND honestly when we lose (T3/T5, the anti-overclaim liar-kill) and 9// EXCEEDS only when a measurement genuinely wins on ratio AND quality (T6). Never self-scored. 10// This banks today's PROVABLE wins (0 patented tools / $0 license) while refusing self-congratulation on 11// compression until it is measured vs a reference.
