{
  "summary": "Reviewed this ARM assembly implementation of P-521 squaring and reduction. It is a straight arithmetic routine with register saves/restores and final stack-guard note emission; I found no concrete indicators of install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence in the target file.",
