What data integrity rules protect

Not every rule is about people. This family holds the structural invariants: an assignment cannot exist in two places at once, history cannot be rewritten, a swap has to be aligned on both sides. They are mostly fixed in code rather than configurable, because they are not policy choices. They are the difference between a roster and a spreadsheet that looks like one.

A locked assignment stays with the person it names
A replacement assignment stays with its replacement
A swapped shift stays with the person who took it
Externally owned pattern blocks cannot be reassigned
Pattern blocks already worked cannot be reassigned
