Number-Set Transformation Workbench
Apply three ordered arithmetic or digit operations across repeated rounds and keep a fully visible trace of every candidate.
Method and limits
The same seed, operation order, constants, range, and round limit always produce the same trace. Distinct in-range candidates are kept; duplicates and out-of-range candidates remain visible.
This first version uses one seed, exactly three visible operation cards, and a fixed skip-duplicates rule. Multi-seed recipes and configurable duplicate policies are deferred. Formula complexity does not create a probability advantage.
