  "summary": "Reviewed this ARM assembly file implementing X25519 basepoint scalar multiplication and field arithmetic, including scalar clamping/mangling, constant-time table lookups, modular multiplication, reduction, and inversion. I found no concrete malicious or supply-chain indicators in the target file: there are no install hooks, network or exfiltration paths, credential access, dynamic code loading, obfuscation, or persistence behavior.",
