  "summary": "Reviewed `aws-lc/crypto/fipsmodule/hmac/hmac.c`, which is a straight HMAC implementation with FIPS service-indicator handling, in-place method dispatch, precomputed-key export/import, and state cleanup. I checked for install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, and persistence behavior, and found no concrete malicious or supply-chain indicators in this file.",
