      "summary": "Reviewed the generated Win64 NASM implementation of SHA-256 block processing in `aws-lc/generated-src/win-x86_64/crypto/fipsmodule/sha256-x86_64.asm`. It consists of register arithmetic, stack shuffling, and embedded SHA-256 round constants only; I found no install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence mechanisms.",
