Coherence as the Structural Condition of Persistence

This paper clarifies the structural role of coherence within the Bellori Framework. Coherence is defined as the preservation of structural relations across successive configurations, enabling structural dependence within configuration chains. The paper establishes that tolerance is not an independent domain, but is derived from coherence and constrained by it. Stability is reformulated as the bounded preservation of coherence within this constrained tolerance, and identity is understood as the recognition of such persistence. The work does not introduce a new model, but makes explicit the structural condition underlying previously defined principles of change, stability, and identity. This establishes coherence as the primary condition governing persistence across physical, biological, and cognitive systems.
