{
  "summary": "Reviewed the generated x86 ChaCha20 assembly and its SSSE3 fast path. It only performs in-memory stream-cipher setup, CPU feature checks, block processing, and tail XOR/writeback; I found no concrete malicious or supply-chain indicators such as install hooks, network or exfiltration logic, credential access, dynamic code loading, obfuscation, or persistence.",
