  "summary": "I reviewed the ARM64 assembly implementation of Curve25519 scalar multiplication in this target file and found no concrete indicators of supply-chain compromise. The file is a self-contained arithmetic routine; I checked for install hooks, subprocess launch, network or credential access, dynamic code loading, obfuscation, persistence tampering, and other hidden payload behavior, and none were present.",
