Target: explain a possible productivity-driven outward opportunity in one direction, while separating model evidence from an economy-wide claim. Prepare: Cards A/E and frontier aid.
- Launch · 2 min. Ask if old Card A allows (4,6).
- Model · 4 min. Old maximum at 4 workshops is 0 circles, so (4,6) is beyond old frontier. E's hypothetical technique offers that one new point with same stated inputs. The evidence does not define every new frontier point; training cost/reproducibility remain unknown.
- Guided reading · 5 min. Contrast E's new possible point with Day 7's movement (2,9)→(3,6) and inside point (2,6). Name what is unchanged and what is claimed to change.
- Practice route · 7 min. Choose Day 8 route; draw old point (3,6), proposed new point (4,6) and a cautious annotation:
possible workshop-side expansion if the trial generalises. - Audit · 4 min. Partner announces national economic growth or zero unemployment. Learner explains why a single fictional studio point cannot establish either.
- Exit · 3 min. “What must be checked before claiming the new method works reliably?” Key: repeated result under comparable inputs and costs, among other evidence.
