The Law of Observation as Irreversible Constraint Pruning: From Probability Fields to Pixels

Attempts to quantify emergent pre-particle structures in dynamical fields reveal an unex-
pected constraint: any successful quantification irreversibly eliminates incompatible configura-
tions. This work elevates that empirical constraint to a general physical principle.
We show that observation arises when irreversible constraints prune ensembles of possible
histories, selecting survivors while permanently eliminating alternatives. A local constraint
density is introduced, and a minimal survival functional is defined using large-deviation prin-
ciples. Observation is not treated as an act or postulate, but as a condition imposed by the
irreversibility of quantification.
Lifetime-resolved simulations of dissipative lattice fields provide direct evidence of selective
survival. Emergent structures exhibit non-Gaussian lifetime distributions, resolution-dependent
lifetime cutoffs, and suppression of incompatible configurations. These results establish irre-
versible constraint pruning as a measurable physical mechanism underlying observation.
