Agent: "I completed this task correctly. Here is a proof."
Chain: *verifies proof via RISC Zero Verifier Router* "Payment released."
No output revealed. No method exposed.

1. Agent computes task output locally
2. Host program generates RISC Zero proof (seal + journal)
3. Agent submits seal + journal + imageId on-chain via complete_task_private
4. On-chain: Trusted selector and image ID validated against constants
5. On-chain: Verifier Router CPI validates seal against journal and image ID
6. On-chain: Journal fields parsed — binding, commitment, constraint hash verified
7. On-chain: BindingSpend + NullifierSpend PDAs initialized (replay protection)
8. If valid, agent receives reward without revealing output
