In some cases specimens are translocated by anthropogenic activities to a new location and a specimen is observed and uploaded to iNaturalist from that location, without being removed from the wild.
In these cases the captive/cultivated tag does not seem appropriate because they are still a wild individual (or are at the best of our knowledge from photos/asking poster).
It is my opinion these should still be considered research grade, because studying translocative movements of animals is a topic of research and thus these sightings are still very useful, they are still correctly identified and they are or were wild at the time of observation.
It would be really cool to a have a flag that could be ticked (in the data quality assessment?) that indicated when you believed a species is observed, in the wild, outside its range, but is not a range extension but an anthropogenically translocated specimen.
