Which data dictionary field flags a candidate profile merge (“Candidate file merged”) using TCC?

I’m using the Candidate entity in TCC (Recruiting Model 17) and can retrieve a candidate-history record that contains the merged (old) candidate’s name and Candidate ID via this projection path:

History,Candidate,History,ApplicationTrackingHistoryItem.Detail

That Detail value includes the “old” Candidate Name and associated Candidate ID that was merged into the “new” profile. Example: John Smith (123456)

What I cannot find is any event indicator/name in the Recruiting 17 model that confirms the record is specifically a profile merge. In the Recruiting app’s Candidate History tab, the same record clearly shows:

• Event Name: Candidate file merged
• Detail: This candidate file has been enhanced with the content of the following file: John Smith (123456)
