about

_codec_bench.nx -- SOVEREIGN SAME-CORPUS codec head-to-head (no-wave, no external tool, no fabricated numbers): our lossless frame codec (fc = MED spatial predictor + Rice) vs sovereign DEFLATE, on IDENTICAL frames. Two deflate baselines: raw (general compressor) and Sub-prefiltered (PNG-class = PNG applies per-row filters then deflate). Verdict per frame = fc size < PNG-class size. All three measured on the SAME bytes -> a real measured exceed, honest by construction.
