A house is torn down and its people must find a new home, but nobody else should move

Rebuild the housing and the simplest code reassigns every citizen from scratch, so the whole town changes address and the people who were happy suddenly walk across the map. This entry shows how to move only those who must, in a way that repeats exactly.

Why this works

People stay where they are unless something forces them out. Handling those who may stay first, and only then placing the displaced, keeps change small and makes the same input always produce the same neighbourhood.

When not to use it

It is not worth it when people are only numbers in a total and have no address, or when you want the town to rebalance toward the best fit, for example the nearest house to work. Then a full fresh assignment is the better, simpler choice.
