{
  "summary": "Reviewed the ARM assembly implementation of P-256 scalar multiplication and its local field-arithmetic helpers. I found no concrete indicators of supply-chain compromise or malicious behavior in this file: there are no install hooks, subprocess launches, network/exfiltration paths, secret harvesting, dynamic code loading, obfuscation/packing, or persistence/tampering behavior; the code appears to be pure elliptic-curve arithmetic.",
