The overview rendered four anonymous module tiles and half a page of empty space, which undersold 63 existing lessons. It now stacks four module sections that list every lesson as a chip with status and variant dots, and the header states the real scope: 4 modules, 63 lessons, 262 variations. Mastery moves from a flat two-variation counter to per-module thresholds (3/4/4/5) backed by persisted variant signatures — a hash over each roll's expected answers. That triples the practice runs to full mastery without authoring a single new lesson, and fixes a dedup hole where the same variation counted twice after a page reload. Existing progress is preserved: `done` is sticky, so raising the bar never revokes a check mark someone already earned. Also fixes `yarn test`, which passed quoted globs Node 20 does not expand — it exited 0 without running a single test. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
