      "summary": "Reviewed the jitterentropy RNG implementation in aws-lc/third_party/jitterentropy/jitterentropy-base.c. It contains entropy collection, self-test, allocation/free, and initialization logic, and I found no concrete indicators of install-time execution, network or exfiltration behavior, credential/secret access, dynamic code loading, obfuscation, or persistence tampering.",

      "summary": "Reviewed `aws-lc/third_party/jitterentropy/jitterentropy-gcd.c`, which implements the jitterentropy GCD health test and helper routines for analyzing timestamp deltas, initializing/freeing buffers, and self-testing the GCD calculation.
