      "summary": "This target file is an ARM64 assembly implementation of modular exponentiation for odd moduli, including local copies of Montgomery helper routines and a final stack note section. I checked it for install-time hooks, subprocess or network/exfiltration behavior, secret access, dynamic code loading, obfuscation, persistence, and other payload-construction patterns, and found no concrete malicious or supply-chain indicators.",

      "summary": "Reviewed the ARM assembly implementation of `bignum_modifier`, which performs constant-time big-number normalization, Montgomery-style reduction, and modular doubling on local buffers. I checked this file for install-time hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, and other hidden payload execution, and found no concrete malicious or supply-chain indicators.",
