{
  "summary": "Reviewed this ARM64 assembly implementation of Ed25519 double-scalar multiplication, including its constant-time table selection, stack usage, and local subroutine calls. I found no concrete indicators of install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain compromise behavior in the target file.",
