Find the exact moment two players' games stop agreeing

In games where every machine calculates the world itself, one tiny difference grows until players see different things, and nobody knows when it began. Comparing a short fingerprint of the game at every step points straight at the first step that differs. Here is the fingerprint and the search, including the two-player case.

Why this works

A drift grows from one small difference, so the first sign is the only useful one. Writing a short fingerprint at every step turns a vague feeling that something is off into a precise moment where the trail starts.

When not to use it

Skip it when one machine owns the world and the others only draw what they are told: nothing can drift. The fingerprints also cannot say why two sides differ, only when, so you still have to look at what changed.
