      "summary": "Reviewed an AVX2 assembly routine that performs in-place modular reduction on two 256-byte regions of a buffer using fixed constants and SIMD arithmetic. I checked for install-time hooks, subprocess execution, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, and persistence, and found no concrete malicious indicators.",

      "summary": "Reviewed the x86_64 assembly for `mlkem_rej_uniform_asm`, which implements rejection sampling of uniform bytes into ML-KEM coefficients. I checked for install-time hooks, network or credential access, dynamic code loading, obfuscation, persistence, and hidden subprocess behavior, and found no concrete malicious or supply-chain indicators in this file.",

      "summary": "Reviewed a C header that only defines ML-KEM parameter constants and compile-time macros for key sizes, compression factors, and variant selection.
