A badge on a specialist's profile names one exact production phase, and means their work in that phase was assessed against the list below. Every check must hold — one failure is a failure.
Each check is written so two reviewers would answer it the same way. "Looks professional" is not a check; "no control carries a non-uniform scale" is.
Build a specialist profile and send work from your phase for review from there. It is checked against this list.
