{
  "summary": "Reviewed `aws-lc/crypto/test/test_util.cc`, which is a test-helper implementation for hex encoding/decoding, PEM/X509 helpers, temp-file/temp-dir creation, OS detection, threading/fork test harnesses, and a few environment-gated test toggles. I found no concrete malicious or supply-chain indicators in this file: there are no install hooks, network or exfiltration logic, credential harvesting, dynamic code loading, obfuscation, or persistence behavior.\nReviewed the ARM assembly implementation of `sm2_montjmixadd`, which appears to be a straight SM2 mixed point-addition routine using local stack temporaries and constant-time conditional selection. I found no concrete signs of install hooks, network or exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain malicious behavior in this file.",
