nx_h264_cavlc_rt_gate.nx

nx_h264_cavlc_rt_gate.nx -- SOVEREIGN round-trip oracle for CAVLC level codec. No third-party reference: the ENCODER (nx_h264_cavlc_enc) and DECODER (nx_h264_cavlc_level) are gated as an inverse pair. (a) BitWriter sanity: write bits, read them back identically. (b) ANCHOR vs canonical code words: encode(+1,sl0) -> "1" (0x80, 1 bit); encode(-1,sl0) -> "01" (0x40, 2 bits). Pins the encoder to the spec. (c) ROUND-TRIP: for many (level, suffixLength) pairs, encode -> decode -> must recover the exact level. Proves both codecs correct (anchor (b) rules out a shared wrong table on these entries). Every value PRINTED. stdout + knowledge/status/h264_cavlc_rt_gate.log. Exit 0/1.
