  "summary": "Reviewed aws-lc/crypto/fipsmodule/bn/gcd_extra.c, which implements constant-time big-number GCD, relative-prime checks, LCM, and modular inverse routines for AWS-LC. I checked for install-time hooks, network or exfiltration behavior, credential or secret access, dynamic code loading, obfuscation, persistence, and hidden subprocess execution; none were present in this target file.\nI reviewed this Perl perlasm generator for MD5 x86 assembly emission. It appears to be a deterministic code generator that only assembles MD5 routines and writes them to the requested output file; I found no concrete indicators of install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain compromise behavior in this target file.\nReviewed aws-lc/crypto/fipsmodule/ml_kem/mlkem/poly.h, which is a C header defining ML-KEM polynomial types, bounds, and function contracts for Montgomery reduction, NTT/InvNTT, add/sub, reduce, and mulcache setup. I found no concrete malicious or supply-chain indicators in this file: there are no install hooks, network/exfiltration paths, credential access, dynamic code loading, obfuscation, persistence, or hidden subprocess execution.",
