The Architecture of Limitation (AoL): Region Transitions and Governance Rules

This record forms part of the Post-Horizon Instrumental Lineage of the Architecture of Limitation research programme. The designation and conditions governing subsequent review are established in K1 Open Concordance Phase: A Structured Validation and Evidence-Alignment Programme for the Open Research Release of AoLOS, v1.0, 2 August 2026, doi:10.5281/zenodo.21758275. The record is retained unchanged as evidence of the conditions, tools, concepts, and architectural pressures through which the programme developed. Inclusion in this lineage does not imply retrospective K1 validation or completion of article-level concordance; any proposition-specific qualification, reanalysis, companion publication, or unresolved pressure will be recorded separately through the phase’s declared review process. -- This companion specification formalizes the region-transition model used by the Architecture of Limitation (AoL) validator. Operating within the Admissible Cognitive Field (ACF) defined by the canonical validator, it specifies how cognitive artifacts move between regions characterized by differing levels of constraint density, scope load, and motion tolerance. The specification provides a region topology, transition grammar, and constraint-based validation model governing admissible movement between cognitive regions. AoL is presented as a non-generative, non-teleological validator that activates only when cognitive artifacts transition across regions without appropriate resizing of boundary claims, scope load, or motion tolerance. Collapse is treated as a diagnostic signal indicating inadmissible transition conditions and enabling reseating rather than correction or replacement. This document is intended as a companion specification to The Architecture of Limitation as a Constraint-Based Validator and should be read as an operational description of transition governance within the broader AoL framework. It does not propose a theory of truth, cognition, or worldview, but specifies the transition rules through which admissibility is evaluated across cognitive regions. This work belongs to the Architecture of Limitation research program.
