{
  "summary": "Reviewed the ARM assembly implementation of `bignum_ksqr_32_64` and its local helper routines for hidden execution or payload behavior. The file is straight-line arithmetic code for big-number squaring; I found no concrete indicators of install hooks, network or exfiltration logic, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain compromise behavior.",
