I found no concrete supply-chain indicators in this file: there are no install hooks, network or exfiltration logic, credential or environment access, dynamic code loading, obfuscation, or persistence behavior.",

      "summary": "Reviewed `aws-lc/crypto/fipsmodule/ml_dsa/mldsa/randombytes.h`, which only declares the `randombytes` interface and a small inline wrapper guarded by configuration macros. I checked for install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, and persistence mechanisms, and found no concrete malicious or supply-chain indicators in this file.",
