Hands-on drills for Lesson 1 — Why model as a cube. They all use the same twelve asset facts from the lesson (six positions × two years) and press one idea until it is muscle memory: a table is never stored — it is the facts, regrouped. Each drill ships red; you drive it to all-✓.

- 🟡 Medium · Build the pivot — the pivot's one primitive is stubbed to
0. Write the single line, and cells, row totals, column totals and the grand total all go green. - 🔴 Hard · The growth trap — the stub averages six growth-rates (11.81 %) where it should divide the totals (7.74 %). Fix the ratio without touching anything additive.
