      "summary": "Reviewed this ARM assembly implementation of `bignum_emontredc_8n_cdiff_base`, which is a Montgomery reduction/multiplication routine using stack-based precomputed modulus differences and NEON integer arithmetic. I checked for install hooks, network or exfiltration behavior, credential/secret access, dynamic code loading, obfuscation, and persistence, and found no concrete malicious or supply-chain indicators in the file.",

I checked for install hooks, network or exfiltration behavior, credential or secret access, dynamic code loading, obfuscation, persistence, and other hidden control transfers; none were present.",
