This article examines a central difficulty in contemporary philosophy: the persistent identification of reality with what is accessible within a given world. Even approaches that aim to overcome classical metaphysics often remain confined to what can be described, measured, or formalised, thereby leaving unexamined the conditions under which such accessibility becomes possible. The paper proposes a strict distinction between reality and world. Worlds are understood as regimes of manifestness in which differences are retained, stabilised, and made available for coordination. Reality, by contrast, is not an entity, structure, or process, but the limit that conditions the possibility of such regimes without entering into them. On this basis, ontology is re-specified as an analysis restricted to what is accessible within regimes of manifestness, while conditions are treated strictly as limits rather than as generative or explanatory principles. A navigational parameter ψ is introduced to register the mode in which integration is retained within regimes, without reducing such configurations to a common metric or ontological hierarchy. The result is a reconfiguration of philosophical analysis: rather than extending ontology, the task becomes to maintain its limits. Evoluism names this discipline and the constraint it enforces.
