My only other suggestion would be
archetypeas a noun
Ooh i like this one also.
I’m not a big fan of abbreviations, especially highly nonstandard ones like
repr or others that involve just dropping arbitrary letters mid-word. It’s ok to require a couple extra keypresses (or an editor/ide macro or automated expansion) to improve clarity. Storage space is cheap; mental computation tax to expand nonobvious abbreviations is not.
