REST API — Workflow Backtests

Method	Path	What it does

POST	/api/workflows/{workflow_id}/backtests/configs	Create a backtest config. Members and owners.
DELETE	/api/workflows/{workflow_id}/backtests/configs/{config_id}	Delete a config. Members and owners. Its runs cascade with it.
PATCH	/api/workflows/{workflow_id}/backtests/configs/{config_id}	Update a config. Members and owners. Past runs are unaffected (they scored against their snapshot + dataset fingerprint).
POST	/api/workflows/{workflow_id}/backtests/configs/{config_id}/lifecycle	Manual lifecycle override (disable / reactivate). Members and owners. Automatic evaluation owns monitoring/decayed; a manual reactivation puts the strategy back under scan.

POST	/api/workflows/{workflow_id}/backtests/runs	Start a backtest sweep. Members and owners.

POST	/api/workflows/{workflow_id}/backtests/studies	Create and start a study: a search over the config’s params and/or the base version’s prompts. Members and owners.
