This is a task made with the "advanced" form where I have set the priority to UBN! on task creation. Inquiring minds want to know if the maniphest.gettasktransactions records will show that priority value.
The hypothesis is that there should be an event that looks something like:
{ "taskID": "<something>", "title": "bd808 raised the priority of this task from \"\" to \"Unbreak Now!\".", "transactionID": "<something>", "transactionPHID": "<something>", "transactionType": "priority", "oldValue": null, "newValue": 100, "meta": [], "comments": null, "authorPHID": "PHID-USER-ll6tmaogat2b5q7tnqas", "dateCreated": "<something>" },
