{
  "summary": "Reviewed this ARM64 assembly source implementing `bignum_emontredc_8n_cdiff_base`, a Montgomery reduction routine with cached limb-difference precomputation and vectorized arithmetic. I found no concrete supply-chain or malicious indicators in the target file: no install hooks, subprocess spawning, network or exfiltration paths, credential access, dynamic code loading, obfuscation, or persistence behavior.",
