{
  "summary": "Reviewed this ARM64 assembly implementation of `bignum_ksqr_32_64_neon`, which performs deterministic big-number squaring and Karatsuba-style limb arithmetic using local helper labels and stack/register save/restore only. I checked for install hooks, subprocesses, network or exfiltration paths, credential or environment access, dynamic code loading, obfuscation/deobfuscation, and persistence tampering, and found no concrete indicators of malicious or supply-chain behavior.",
