      "summary": "Reviewed the x86-64 assembly routine for `bignum_double_sm2`, which performs constant-time modular doubling for the SM2 field with standard ABI shims and stack metadata. I checked for install-time execution, network or exfiltration, credential access, dynamic code loading, obfuscation, and persistence, and found no concrete malicious or supply-chain indicators in this file.",

      "summary": "Reviewed the x86-64 assembly routine that halves a 256-bit SM2 field element modulo the curve prime. It contains a small arithmetic-only implementation with ABI shims and no install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence behavior in the target file.",
