  "summary": "Reviewed the generated macOS x86_64 ChaCha20 assembly in this target file. It contains only the expected cipher state setup, round operations, SIMD/data movement, buffer XOR, and epilogue/return code; I found no install hooks, network or exfiltration logic, credential access, dynamic code loading, obfuscation, or persistence behavior.",
