_race5_claude.nx

_race5_claude.nx -- the CLAUDE lane for autonomy race 5 (handwritten single-pass RIFF/WAV chunk census; the yardstick the team lane races against). Lane contract: read /tmp/race_input.bin, print NCHK= FMT= DATA= LIST= RSZ= as key=int lines. Census semantics (the assignment): NCHK = well-formed chunk count, -1 = REFUSED (truncated / bad magic / overlong length); finds = body offset RELATIVE to the chunk area (byte 12), -2 when refused or absent; RSZ = declared u32le size at byte 4 whenever the 12-byte header is intact, -2 otherwise. Odd chunk bodies are padded to even (RIFF law). license_tier: ORIGINAL
