/**
 * Example: Using pot-sdk as an ERC-8004 Validation Provider
 *
 * This example shows the full flow:
 * 1. Verify an agent's output using pot-sdk
 * 2. Create an attestation (TP-VC)
 * 3. Build ERC-8004 evidence payload
 * 4. Generate a validation record for the Validation Registry
 * 5. Generate a trust declaration for agent registration
 *
 * In production, you would:
 * - Pin the evidence to IPFS
 * - Submit the validation record to the ERC-8004 Validation Registry contract
 * - Include the trust declaration in your agent's registration metadata
