Make a seeded world come out the same no matter where you walk first

Two players typing the same world code should find the same mountains, but if the land is made as you walk, the order of your steps can change it. This entry shows the AI how to give every patch of land its own repeatable number.

Why this works

If land is made while walking, its look must not depend on the walk. Give each patch its own starting number built only from the world code and its place, so a patch is the same whether it is met first, last, or after a restart.

When not to use it

It is the wrong approach when land should react to what happened before, such as terrain that spreads or a world shaped by earlier players' choices. Then store the result, not the recipe, or the same code will rebuild the wrong land.
