about

nx_dxbc_gate.nx -- D1 proof: parse a byte-exact, SPEC-FAITHFUL DXBC container + decode its SM5 shader tokens. The fixture is hand-built to the documented DXBC layout (magic/checksum/offset-table/SHEX-chunk) with a real token stream (dcl_temps, mov, mad, dp3, sample, ret at correct opcode+length encodings). Proves the container walk + chunk-find + instruction classification. Neg-control: non-DXBC bytes are rejected. HONEST: fixture is spec-built, not a shipped game's shader (D1b = feed a real .dxbc). license_tier: ORIGINAL expect_exit: 0
