Create a mutable draft dataset version for a dataset group. Drafts use version_number = -1 until they are saved as a published version.

​
Behavior Notes

  • Only one draft can exist per dataset group at a time; creating another draft returns 409.
  • Without source_dataset_id, PromptLayer creates an empty draft and returns 201.
  • With source_dataset_id, rows are copied from the source dataset asynchronously and the endpoint returns 202.
  • The source dataset must belong to the same dataset group.
