about

nx_p256_fieldmul_full_bench.nx -- the FULLY-optimized P-256 field multiply: fused __mul256_wide (MULX/ADCX/ADOX) multiply + deferred-carry fast Solinas reduce, vs the production p256_field_mul. Both components are individually proven bit-exact; this verifies the COMPOSITION (correctness pre-check) then times it. Dependent-chain harness (DCE/hoist-proof). Uses __mul256_wide -> build via nx_cand_build_run (candidate compiler; zero live risk). expect_exit: 0 license_tier: ORIGINAL
