      "summary": "Reviewed the ARM assembly implementation of `edwards25519_scalarmulbase_alt`, which performs scalar reduction, constant-time table lookup, point addition, and final inversion for Ed25519 basepoint multiplication. I found no concrete supply-chain or malicious indicators in this file: there are no install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence logic.",
