- a graph reused across a backtest grid held each run's complete state for its whole life
- the state log is written from the run's own state; the ticker attribute it read is removed
- the Yahoo vendor owns get_company_profile and get_closes; agent_utils and the graph no longer import yfinance
- a test keeps vendor libraries inside dataflows
- every analyst calls its tools through the router, offline; the decision is parsed and logged
- free-text and structured-output paths, and resume from a checkpoint
- remove the unused mock_llm_client fixture
