"""First Run end-to-end with NO database, via the harness console entrypoint.

`harness.console.run_one` wires the full AraFirstRunPipeline (Ingestion ->
Baseline -> Modelling) against in-memory fakes. This proves the whole flow runs
start-to-finish with no Session ever opened and yields a multi-measure Plan;
`tests/harness/test_console.py` covers the entrypoint's print/return contract.
