{
  "summary": "Reviewed the generated x86_64 ChaCha20 assembly implementation in `pregenerated/chacha-x86_64-elf.S`, including its constants, SSSE3 and AVX2 code paths, tail handling, and epilogue logic. I found no concrete indicators of install-time execution, network or exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain compromise behavior in this target file.",
