{
  "summary": "Reviewed `aws-lc/crypto/fipsmodule/hkdf/hkdf_test.cc`, which is a deterministic HKDF test suite covering RFC 5869 vectors, Wycheproof inputs, and CAVP feedback-mode cases. I found no concrete malicious or supply-chain indicators in this file: there are no install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence behaviors.\nReviewed the Perl perlasm generator for ARMv8 SHA-512/SHA-256 assembly. It only emits deterministic assembly and tables, with a build-time pipe to `arm-xlate.pl` and a self-read/eval pass for template arithmetic; I found no concrete indicators of install hooks, network or exfiltration, credential access, hidden downloads, obfuscation, or persistence in this file.",
