Executable
Materials and quantities reconcile with the plan; steps have completion checks.
Make
Complete projects and experiences belong here when they have quantities, a start-to-finish sequence, safety limits, completion checks and honest unknowns—not just an idea card.
First complete experience
A reuse-first indoor treasure hunt for a small group, with a complete host sequence, scalable quantities, conservative safety boundaries, an owned-items-aware budget planner and downloadable working files.
Materials and quantities reconcile with the plan; steps have completion checks.
Owned items, substitutions and unknown prices are separate. Missing cost is not $0.
Physical projects publish their operating limits. Generated visuals are labeled as concepts, never presented as real test photos.
The Concept Library contains many future make/build directions that are not yet complete projects.
