      "summary": "This file is a hand-written ARM assembly implementation of `sm2_montjdouble`, performing SM2 elliptic-curve point doubling with Montgomery-domain big-integer arithmetic and stack/register save-restore only. I checked the target for install-time hooks, subprocess execution, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, and persistence, and found no concrete malicious or supply-chain indicators.",
