  "summary": "Reviewed the generated x86 ChaCha20 assembly in aws-lc/generated-src/linux-x86/crypto/chacha/chacha-x86.S, including the ChaCha20_ctr32 and ChaCha20_ssse3 routines and their embedded constants. I found no concrete indicators of install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other hidden payload behavior; the file is consistent with normal cryptographic SIMD/arithmetic implementation code.",
