{
  "summary": "Reviewed the target ARM assembly routine implementing `bignum_ksqr_16_32` and its local 8x8 squaring helper. The file is pure arithmetic code with register saves/restores and stack-note metadata; I found no concrete signs of install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence tampering.",
