Java sample
Prove that arbitrary transaction intent cannot reach a JVM signer through the Torq client.
Developer Preview. Use the JVM client supplied with your approved application. Only a verified, typed Torq workflow may reach your signer boundary.
This executable negative sample confirms that raw caller-created transaction intent fails closed before simulation or signing.
