"""Nova Forge E2E Demo — Full infrastructure verification using only Nova models.

Exercises every subsystem with real Nova Lite + Nova Pro API calls:
  1. Project scaffold (forge new)
  2. Session management (init, autonomy, compliance)
  3. Task store (CRUD, wave computation)
  4. Formation selection (DAAO routing)
  5. ForgeAgent tool-use loop (Nova Pro as brain, writing real code)
  6. Hook enforcement (pre/post hooks fire)
  7. Risk classification (guards block dangerous ops)
  8. Audit trail (JSONL entries written by hooks)
  9. Team creation (formation-based team lifecycle)
  10. Migration (detect + migrate legacy project)
  11. Gate review (Nova Lite reviews artifacts)
  12. Schema validation
