{
  "summary": "Reviewed `aws-lc/crypto/fipsmodule/ml_kem/ml_kem.c`, which is a native ML-KEM wrapper layer that wires in self-tests, buffer-length checks, and keypair/encapsulate/decapsulate entry points for three parameter sets. I did not find concrete malicious or supply-chain indicators in this file: there are no install hooks, network or exfiltration calls, credential/secret harvesting, dynamic code loading, obfuscation, or persistence behavior.\nReviewed the jitterentropy noise-source implementation in `jitterentropy-noise.c`, including loop-shuffling, hash mixing, memory-access noise, and random-block generation. I found no concrete supply-chain or malicious indicators: no install hooks, network or exfiltration paths, secret/credential access, dynamic code loading, obfuscation/deobfuscation, or persistence/tampering behavior in this file.",
