Four learners. Forty-eight lessons. Each on their own real work.

Pick a learner and walk their arc. Each lesson opens with an exhibit note telling you what to look for; the lessons themselves are the generated product — Say-See-Do cycles on that learner's real artifacts, every claim doc-set-cited, every objective tied to a standard you can click into. The four arcs are deliberately different: the same system, four genuinely different tutoring relationships. Each ends in a mastery ledger.
