      "summary": "Reviewed the ARM assembly implementation of `bignum_inv_sm2`, which computes SM2 modular inversion with local stack temporaries and register-only arithmetic. I checked this target file for install-time hooks, network or credential access, dynamic code loading, obfuscation, persistence, and other hidden payload behavior, and found no concrete malicious or supply-chain indicators.",
