{
  "summary": "Reviewed `aws-lc/crypto/fipsmodule/ml_kem/ml_kem_ref/polyvec.c`, which implements ML-KEM polynomial-vector compression, decompression, serialization, NTT transforms, and arithmetic over in-memory buffers. I found no concrete indicators of install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain compromise behavior in this file.\nReviewed `aws-lc/crypto/pem/pem_pk8.c`, which implements PKCS#8 private-key encode/decode helpers and file/BIO wrappers around OpenSSL-style password callbacks and encryption/decryption routines. I checked for install-time hooks, hidden subprocess execution, network or exfiltration paths, credential harvesting, dynamic code loading, obfuscation, persistence, and unrelated system probing; none were present in this target file.\nReviewed `aws-lc/crypto/chacha/chacha.c`, which is a ChaCha20/HChaCha20 implementation with endian handling and optional assembly dispatch. I found no concrete malicious or supply-chain indicators in this file: there are no install hooks, network/exfiltration code, credential access, dynamic code loading, obfuscation, or persistence behavior.\nReviewed `aws-lc/crypto/fipsmodule/cipher/internal.h`, which is a C header exposing cipher and AEAD type definitions, constants, and function prototypes for AES/GCM/TLS state serialization. It contains no install hooks, network or exfiltration code, credential access, hidden downloads, dynamic code loading, obfuscation, or persistence behavior.",
