"""End-to-end integration: spec-and-review workflow via real OpenRouter.

Cost budget: ~$0.05 per run. Skipped if no API key is configured.

Verifies:
  - Engine creates a RunRow and 3 RunPhaseRow rows
  - Each phase writes a schema-valid artifact via deepagents write_file
  - Final report json + md are written under worktree_root
  - LlmCallRow rows are persisted (CostMiddleware recorder is wired)
  - BudgetLedgerRow rows accumulate spend
  - run.state == COMPLETED
