/**
 * Vaultfire v2 — On-Chain Functional Verification
 * Tests that every v2 contract actually works correctly on the live chain.
 * 
 * For each contract, verifies:
 * 1. Constructor args are correct (identity, bonds, reputation registries)
 * 2. Owner is set correctly
 * 3. View functions return expected values
 * 4. Write functions work (owner-only operations)
 * 5. Access control works (rejects unauthorized callers)
 * 6. Cross-contract integration with v3 core contracts works
