## Notes

* No authentication is required for this endpoint
* This endpoint provides the most comprehensive view of a task
* MMRs array will be empty if no MMRs were used
* If task\_hash or output\_tree\_root are not stored in the database, they will be extracted from the task results if available
* The program\_hash will fallback to the HDP core program hash if not specified
