      "summary": "Reviewed the ARM assembly implementation of `bignum_montinv_sm2`, which performs fixed big-number arithmetic for SM2 Montgomery inversion and stack/register management only. I checked for install-time hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence tampering, and hidden subprocess execution, and found no concrete malicious or supply-chain indicators in this file.",
