      "summary": "Reviewed an ARM assembly implementation of `edwards25519_scalarmuldouble_alt` that performs Ed25519 double-scalar multiplication, field arithmetic, and an embedded precomputed table. I found no concrete supply-chain or malicious indicators in the file: there are no install hooks, network or exfiltration paths, credential access, dynamic code loading, persistence changes, or obfuscation beyond the expected constant-time arithmetic and table lookup logic.",
