Risk Receipt Agent

A pre-trade gate for autonomous market agents on Arc.

Before an agent can execute, it must produce a risk receipt that another agent can verify onchain.

Why this exists: Autonomous agents should not be able to move capital just because they decided to. Risk Receipt Agent creates a verifiable checkpoint before execution.
