      "summary": "Reviewed the ARM assembly implementation of `bignum_montmul_p384_neon`, which performs a fixed Montgomery multiplication on P-384 limbs with stack save/restore and no apparent side effects beyond arithmetic and result storage. I found no concrete indicators of install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence behavior in this file.",
