Take-home: cost-attribution model
Explain the practical point behind "Cursor explicitly wants the person who builds the model, not the person who schedules the meeting about the model."
Step 1 of 3
Set a 4-hour timer and open a blank spreadsheet. The prompt: attribute Cursor's inference spend across features, then recommend where to cut 15% of COGS without wrecking the product. This is the round the whole loop is built around - Cursor explicitly wants the person who builds the model, not the person who schedules the meeting about the model.

This capstone simulates the four hardest middle stages - take-home, systems, execution and values. Step through to see what each one is actually grading.
The deliverable is two artifacts that travel together: a cost model with every assumption visible and a one-page recommendation a founder could act on without a follow-up call. The model proves you can do the math. The page proves you can make a call.
