{
  "summary": "Reviewed `aws-lc/crypto/perlasm/x86gas.pl`, a Perl helper for emitting x86 GNU-style assembly directives and symbol decoration for different object formats. I checked for install-time execution, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, and persistence tampering, and found no concrete malicious or supply-chain indicators in this file.\nReviewed the target file `aws-lc/crypto/fipsmodule/ml_kem/mlkem/native/x86_64/src/poly_decompress_d11.S`, which is a hand-optimized AVX2 assembly routine for ML-KEM polynomial decompression and is explicitly marked as auto-derived from public-domain Kyber code. I found no concrete supply-chain or malicious indicators in this file: no install hooks, no network or exfiltration behavior, no credential access, no dynamic code loading, no obfuscation/packing, and no persistence or environment tampering.\nReviewed this header-only API declaration file for PKCS#8/PKCS#12 handling. It contains function prototypes, comments, and error-code constants only; I found no concrete indicators of install hooks, network or exfiltration paths, credential harvesting, dynamic code loading, obfuscation, persistence, or other supply-chain compromise behavior in the target file.\nReviewed the ARM64 assembly implementation of `bignum_montsqr_p384_alt`, which performs a constant-time Montgomery square for P-384 using only register arithmetic, conditional selects, and stores to the provided output buffer. I checked for install-time hooks, network or exfiltration behavior, dynamic code loading, obfuscation, credential access, and persistence/tampering, and found no concrete malicious or supply-chain indicators.",
