For the first answer criterion
for the Enlightened badge, is the first answer the one
- that remains, excluding deleted answers; or
- that ever was, including deleted answers
As for the suggestion, if it were the latter, can we please make it the former? It would make sense to exclude squatters from the equation if they later retract their answer from the question (having reached no good solution).
EDIT - ChrisF has posted convincing proof that it is the former, so - great stuff, SE!
