about

nx_decode_kind_test.nx -- EXHAUSTIVE proof of the RV64IM decoder gate-network (nx_decode_kind_synth) vs the behavioral nx_rv64im_decode_kind. decode_kind depends only on {opcode[6:0], funct3[14:12], funct7[31:25]} (17 bits), so this sweeps ALL 2^17 = 131072 combinations -- a complete proof, not a sample. Known answer: "131072 131072" (ok total), exit 0.
