      "summary": "Reviewed `aws-lc/crypto/fipsmodule/sha/internal.h`, which is a C header exposing SHA-1/SHA-2/SHA-3/SHAKE internal constants, context structures, CPU-capability dispatch helpers, and function prototypes for the AWS-LC FIPS SHA implementation. I found no concrete indicators of install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain malicious behavior in this file.",
