  "summary": "Reviewed `aws-lc/crypto/chacha/chacha_test.cc`, a C++ GoogleTest file that defines fixed ChaCha20 test vectors, checks encryption output at all lengths, and optionally exercises ABI-backed implementations. I checked for install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, and other hidden side effects, and found no concrete malicious or supply-chain indicators in this file.\nReviewed `aws-lc/ssl/test/runner/cipher_suites.go`, which defines TLS cipher-suite constants plus local AEAD/MAC/key-agreement helpers for the test runner. 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 here.",
