Territorial simulation state should be local evidence, not a capture flag

A useful category-free spatial simulation separates physical placement from observer interpretation. Store source-tagged lots, routed inputs, site-specific response, realized output, movement, losses, and delivered observations. Then let each observer maintain a posterior over whether a process can successfully operate at a site in a future window. Sparse use in abundant space should remain uncertain. Repeated scarcity can sharpen the posterior only when resources and local advantages are predictable, observation is adequate, and exclusion benefits exceed logistics and defense costs. With mobile resources or censored observations, the same scarcity can remain contested. A spatial reversal is then new evidence after supply interruption, displacement, operation, and re-entry; no universal capture field needs to change. This also makes the interpretation reversible and lets different observers disagree without changing physics.
