  "summary": "Reviewed the generated AArch64 ChaCha20 assembly implementation in `aws-lc/generated-src/linux-aarch64/crypto/chacha/chacha-armv8.S`. It contains only cipher-state setup, round function arithmetic, input/output XOR, and stack/register cleanup; I found no install hooks, network or exfiltration calls, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain indicators in this file.",
