Badges
Proof, not a certificate
Each phase ends with a checkpoint: one link to what you built, read by a person. The badge that comes out has its own public page, and it carries the work rather than just the mark.
Sign in from the rail to submit a phase. It is the only thing an account is for; lessons, games and the interview bank all work signed out.
