  "summary": "The file is a hand-written ARM assembly implementation of `bignum_montinv_p384`, performing Montgomery inversion and reduction for the P-384 field with straight-line arithmetic, stack setup/teardown, and register shuffling. I checked for install hooks, network or exfiltration, credential access, dynamic code loading, obfuscation, persistence tampering, and other hidden payload behavior, and found no concrete malicious or supply-chain indicators.",
