{
  "summary": "Reviewed the ARM assembly implementation of Ed25519 double-scalar multiplication plus its local arithmetic helpers and embedded precomputed table. I found no concrete supply-chain or malicious indicators: there are no install hooks, network/exfiltration behavior, credential access, dynamic code loading, obfuscation/deobfuscation, persistence tampering, or other hidden payload execution in this target file.",
