      "summary": "Reviewed the ARM assembly implementation of `bignum_emontredc_8n_cdiff`, which performs in-place Montgomery reduction with precomputed modulus differences and stack-local caching. I checked the file for install-time hooks, subprocess spawning, network or exfiltration paths, credential access, dynamic code loading, obfuscation, and persistence behavior, and found no concrete malicious or supply-chain indicators.",
