      "summary": "Reviewed an ARM64 assembly implementation of P-521 Jacobian scalar multiplication plus local field-arithmetic helpers. It only performs arithmetic, constant-time table selection, and stack/register management; I found no install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence in this file.",
