{ experimentId: string, currentRunId: string | null, recommendedAction: RecommendedAction }
Cause
Start was called but the draft is identical to the Run already live. Starting it would open a second Run that measures the same configuration, splitting one cohort across two Runs for no reason.
Fix
Edit the draft so it differs from the current Run, then Start. details.currentRunId is the Run it matched, or null when no Run has ever started.
