Scaling Limits of an ℓ¹ Causal Lattice

This public-cleanup release replaces an earlier, overly broad version of the paper with a conservative structural framework for L1 causal-lattice defect systems. The revised paper treats finite L1 lattice dynamics as an obstruction-accounting framework: local defects, admissible repairs, quotient residuals, finite propagation, coarse-graining loss, and Regge-style curvature bookkeeping. It preserves the useful mathematical and structural content while removing or quarantining claims that suggested a completed derivation of quantum mechanics, general relativity, the Standard Model, dark matter, dark energy, black-hole physics, or physical unification. The central claim is now deliberately narrow: local L1 update rules can model finite propagation and residual curvature-like bookkeeping on discrete structures, and the passage from L1 defect data to smoother L2-style continuum descriptions is lossy. This helps clarify how microscopic defect information may be hidden by coarse-graining, without claiming that the resulting framework is a validated physical theory. In later GTLA/Omega terminology, this paper should be read as legacy structural material feeding the obstruction and representation layers. It contributes ideas about defect, repair, residual, finite propagation, and coarse-grained representation loss. It does not terminalize physical authority and does not replace domain-specific empirical or mathematical validation.
