  "summary": "Reviewed this header, which only defines compile-time feature macros and small AVX2 capability-gated inline wrappers that dispatch into existing native ML-KEM routines. I found no concrete signs of install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence behavior in the target file.\nReviewed this x86-64 assembly implementation of `bignum_sqr_8_16`, which is a straight-line big-integer squaring routine using BMI2/ADX instructions and ABI save/restore macros. I checked for install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, and persistence/tampering, and found no concrete malicious or supply-chain indicators in the target file.\nReviewed this x86-64 assembly implementation of `bignum_sqr_p521`, which performs a constant-time modular squaring routine for P-521 and only manipulates registers and stack storage for arithmetic. I found no concrete indicators of install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain compromise patterns in the target file.",
