nx_h264_deblock_gate.nx

nx_h264_deblock_gate.nx -- REFEREE for the normal luma deblocking filter. Hand-derived from the REAL MB edge (139|142, bS=3, QP=31): alpha[31]=28, beta[31]=8, tc0[3][31]=3; ap=aq=0<beta -> tc=5; delta=Clip3(-5,5,13>>3=1)=1 -> p0=140,q0=141; p1=140,q1=141. line [139,139,139,139,142,142,142,142] -> [139,139,140,140,141,141,142,142] Plus: a flat edge (all 142) -> unchanged (|p0-q0|=0, but filter runs; delta=0 -> no change). And table anchors: alpha[31]=28, beta[31]=8, tc0(3,31)=3, alpha[16]=4. NOTE 2026-06-17: beta table was CORRECTED (memorized values were wrong from qp>=22; beta(31) is 8 not 9, ffmpeg h264_loopfilter.c verbatim). This corrected the full-frame deblock to 100% bit-exact. Memorized deblock tables = unreliable, same lesson as VLC tables. Every value PRINTED. stdout + knowledge/status/h264_deblock_gate.log. Exit 0/1.
