{
  "summary": "Reviewed the scalar recoding helper in `aws-lc/crypto/fipsmodule/ec/util.c`, which contains only fixed arithmetic and explanatory comments for constant-time elliptic-curve window recoding. I found no concrete indicators of install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence in this file.\nReviewed the ARMv4/NEON GHASH/GCM assembly implementation in this generated source file. It is a self-contained cryptographic routine with no install hooks, network or exfiltration logic, credential access, dynamic code loading, obfuscation, or persistence behavior, and I found no concrete malicious or supply-chain indicators.\nAArch64 assembly implementing the SHA3 Keccak-f1600 permutation for two parallel states, with fixed loads/stores, lane transposition, and 24 rounds over caller-supplied round constants. I reviewed it for hidden install-time execution, network or exfiltration behavior, credential access, dynamic code loading, obfuscation/deobfuscation, persistence, and other payload-like control flow, and found no concrete malicious or supply-chain indicators.\nReviewed aws-lc/include/openssl/target.h, which is a compile-time platform-detection header that sets architecture, OS, sanitizer, and embedded-target macros and conditionally disables assembly for specific environments. I checked for install hooks, network or exfiltration behavior, credential/secret access, dynamic code loading, obfuscation, and persistence tampering, and found no concrete malicious or supply-chain indicators in this file.",
