Deleting a dataset does NOT delete its collections — they become standalone (their datasetId is not cleared).

dreamlake delete dataset "training-v1" --project robotics@alice

Error	Cause
`collection not found` / `dataset not found`	Name doesn't exist or already deleted
`project not found`	Space or namespace doesn't exist
