Hard Constraints Only, For Now
Captions available
The idea
A hard constraint makes a combination flatly legal or illegal; a soft constraint merely prefers some assignments to others — and this unit is hard constraints only.
In practice
"The drummer cannot be on two stages at once" is hard; "the headliner would rather play late" is soft.
Where people slip
Preference gets its own arithmetic in Unit 7 — a declared scope, not an oversight.
