{
  "summary": "Reviewed the generated ARM64 MD5 block implementation in `aws-lc/generated-src/linux-aarch64/crypto/fipsmodule/md5-armv8.S`. It is straight-line cryptographic assembly with register saves/restores and MD5 round arithmetic only; I found no concrete indicators of install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other hidden payload behavior.",
