      "summary": "Reviewed the ARM64 assembly implementation of `bignum_ksqr_32_64` and its inlined helper routines. I checked for install-time hooks, subprocesses, network or credential access, dynamic code loading, obfuscation, and persistence behavior; the file is limited to deterministic big-number arithmetic and register/stack management, with no concrete malicious or supply-chain indicators found.",
