      "summary": "Reviewed the ARM64 assembly implementation of `bignum_emontredc_8n_neon`, which performs Montgomery reduction over bignum limbs using register arithmetic and NEON instructions. I found no concrete signs of install-time execution, network or exfiltration, credential access, dynamic code loading, obfuscation, or persistence behavior in this file.",
