  "summary": "The target file is generated AArch64/Windows assembly for ChaCha20 (`ChaCha20_ctr32_nohw` and `ChaCha20_ctr32_neon`) with constant tables, block processing, and a tail-byte XOR path. I checked the data section, control flow, and all reachable code for install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other hidden payload behavior and found no concrete malicious or supply-chain indicators.",
