  "summary": "I reviewed `aws-lc/crypto/hmac_extra/hmac_test.cc`, which is a deterministic HMAC test suite covering normal HMAC APIs, precomputed-key flows, and Wycheproof vector validation. I found no concrete supply-chain or malicious indicators in this file: there are no install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation/deobfuscation, or persistence/tampering logic.",
