Undivided /
Seven tests, then freeze.
A war you can trust is a war you can re-run.
Before any tuning is allowed to stand, it has to survive a functional test. Undivided now carries a seven-test suite on its own test map: the rules that decide who parries what, the dominance arithmetic that turns kills and populations into pressure, the wound and reinforcement systems, and the gates that let a faction climb the class ladder. The suite is order-independent and runs from the editor's automation window.
With all seven green the baseline was frozen. Every number that shaped the war lives in one data asset, and that asset is the thing under version control, not a memory of what felt right on Tuesday.
The practical effect is that the visual work that followed, weapons, terrain, the flythrough, could be reckless, because nothing it touched could change the maths without a test going red.
