{
  "summary": "Reviewed `aws-lc/crypto/dilithium/pqcrystals_dilithium_ref_common/params.h`, which is a compile-time constants header defining Dilithium parameter sizes and packed-byte formulas for the supported modes. I found no concrete malicious or supply-chain indicators in this file: there are no install hooks, subprocesses, network or exfiltration paths, credential access, dynamic code loading, obfuscation, or persistence behavior.\nReviewed `aws-lc/third_party/s2n-bignum/x86_att/p521/bignum_tolebytes_p521.S`, a short x86-64 assembly helper that copies a 66-byte P-521 bignum from one buffer to another with Windows ABI register shims. I checked for install hooks, network or exfiltration, credential access, dynamic code loading, obfuscation, persistence, and hidden subprocess behavior; none were present.\nReviewed `reduce.c`, which contains small finite-field reduction helpers (`fqmul`, `reduce32`, `caddq`, `freeze`) for Dilithium arithmetic. I checked for install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, and persistence behaviors, and found no concrete malicious or supply-chain indicators in this file.\nReviewed `aws-lc/crypto/kyber/pqcrystals_kyber_ref_common/params.h`, which is a compile-time parameter header for Kyber namespace and size macros. 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/x509/v3_akeya.c`, which is a small OpenSSL-style ASN.1 schema and helper stub for the `AUTHORITY_KEYID` X.509 extension. I checked for install-time execution, hidden subprocesses, network or credential access, dynamic code loading, obfuscation, and persistence behavior, and found no concrete malicious or supply-chain indicators.",
