      "summary": "Reviewed `aws-lc/crypto/fipsmodule/bn/exponentiation.c`, which implements big-number modular exponentiation helpers, Montgomery reduction paths, and constant-time table lookup logic for cryptographic operations. I checked for install-time hooks, subprocesses, network or secret exfiltration, dynamic code loading, obfuscation/deobfuscation, and persistence tampering, and found no concrete malicious or supply-chain indicators in this file.",
