Ship one, and defend the rung (capstone)

The graduation move for this area, parallel to the B12 capstone but centered on the app-building judgment this track teaches. Pick the one tool from B13 you'd use this week, get it genuinely working on real data, then write the two-line 'rung memo': which surface you built it on — Artifact, Claude Code, or a Cowork skill (no-code / low-code / full-code) — and whether you'd move it if you rebuilt. That memo is the evidence you learned the spectrum, not just the app. You graduate with a tool a colleague could use and a defended reason for where it lives.
