about

nx_nv1_transcode.nx -- NV1 raw->LPC transcoder probe (REAL-DATA evidence for the LPC rung): reads an NLC1 container from /tmp/nv1_in.bin, rewrites every 'A' (raw PCM) chunk as an 'L' (LPC) chunk, copies V chunks and the terminator, writes /tmp/nv1_out.bin, validates the output, then SELF- CHECKS by decoding every L chunk back and byte-comparing against the original PCM. Prints TRANSCODE markers (judge by markers, not $?-echo). license_tier: ORIGINAL
