      "summary": "Reviewed the jitterentropy health-test implementation in `aws-lc/third_party/jitterentropy/jitterentropy-health.c`, which contains the lag predictor, adaptive proportion, and repetition-count/stuck-bit checks plus a FIPS failure callback. I found no concrete malicious or supply-chain indicators in this file: no install-time execution, network or exfiltration code, credential access, dynamic code loading, obfuscation, persistence, or hidden subprocess behavior.",

      "summary": "Reviewed the C header `aws-lc/third_party/jitterentropy/jitterentropy-health.h`, which only declares jitterentropy health-check APIs and a small inline delta helper. I checked for install-time hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, and hidden subprocess execution, and found no concrete malicious or supply-chain indicators.",

      "summary": "Reviewed `aws-lc/third_party/jitterentropy/jitterentropy-noise.c`, which implements in-process jitter/entropy collection by mixing timer deltas, hash-state updates, and optional memory-access noise.
