The EffectiveManifold module formalizes refinement relations among recognizers to define effective manifold structures in recognition geometry. It introduces IsFinerThan' together with DirectedRefinement, RefinementConverges, DimensionInvariant and NonCollapseCondition, plus supporting lemmas on monotonicity and convergence. The module rests on the quotient and composition constructions and supplies the hypotheses needed for manifold-like behavior without collapse.

claimLet $R_1,R_2$ be recognizers on configuration space $C$. Write $R_1\preceq R_2$ when $c_1\sim_{R_1}c_2$ implies $c_1\sim_{R_2}c_2$. The module defines DirectedRefinement, RefinementConverges, DimensionInvariant and NonCollapseCondition, together with the hypothesis package EffectiveManifoldHypotheses.

background

Recognition Geometry begins with the quotient construction $C_R=C/\sim_R$ (Quotient module) that collapses configurations indistinguishable by a recognizer. The Composition module extends this to composite recognizers and states the Refinement Theorem. EffectiveManifold supplies the refinement order and the auxiliary conditions (monotonic separation, automatic non-collapse, convergence to identity) required to obtain manifold-like quotients that preserve dimension.

proof idea

This is a definition module. It declares the refinement preorder IsFinerThan' and records its reflexivity and transitivity as one-line lemmas. The remaining declarations (monotone_separation_of_refinement, nonCollapse_monotone_automatic, convergence_implies_identity, status_summary) are direct consequences of the definitions; no substantial tactic scripts appear.

why it matters in Recognition Science

The module supplies the refinement infrastructure that the Refinement Theorem (Composition module) requires in order to produce effective manifolds. It encodes the non-collapse and dimension-invariance conditions that keep the quotient compatible with the eight-tick octave and $D=3$ of the forcing chain. No downstream declarations are listed yet.
