Hi,
Triage: clerks check to make certain H&C/PRRA applications are prepared & decision ready for officers when they're finally pulled off of a shelf for a decision. That's all that triage means.
Discrimination: A rough round up of the nature of an H&C application. H&C decision-makers cannot consider refugee type decisions about persecution, however alleged discrimination is a factor for them. They do make refugee type decisions in PRRAs only.
H&C Officers only make decisions on AIP for H&C and positive or negative for PRRA. For stage two after a positive H&C (or a positive PRRA) there are lower level officers for that processing.
So, your application likely has elements alleging some sort of discrimination and the file was with the Triage team, or unit or whatever they call it. They issue files in bundles of similar cases to officers, so they'll give an officer 5 files from the same place with the same general complaint. They research that place as the open source data will likely correspond with one or more cases, and they save time and energy that way.
It's just sorting casework inside of a large inventory.
