      summary: Make a security decision for a request
      description: Connect RPC Decide method. The SDK sends request details and the configured rules; the service returns a decision (ALLOW, DENY, CHALLENGE, or ERROR) with the reason. Over native ConnectRPC this is a gRPC/HTTP-2 call; the equivalent HTTP/1.1 + JSON POST is shown here. Authentication is the Arcjet site key sent by the SDK.
