Change the brief, keep the discipline
Sandbox provides room to experiment with layouts, systems, and mountain ideas outside the campaign's normal pressure. Daily Challenge gives every operator a shared deterministic problem to solve and compare.
Use both modes to learn causes, not just outcomes. Record the objective, constraints, and changes that produced the result.
- Sandbox: explore and prototype
- Daily Challenge: solve a shared fixed problem
- Campaign: build a durable operating company
- Field Guide: inspect deeper rules and references
