I found no concrete indicators of install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence; the file appears limited to choosing and initializing entropy sources plus test-only overrides.",

      "summary": "Reviewed `aws-lc/crypto/fipsmodule/rand/entropy/internal.h`, a C header that declares entropy-source interfaces, hardware RNG helpers, and test-only hooks for the RAND subsystem.
