This paper reframes entropy as a filtrational concept rather than a statistical one. It reinterprets topological organization as an effect of bifurcational access, not emergent order. The work bridges thermodynamics, ontogenesis, and post-structuralist metaphysics to present entropy as a tension field reorganizing availability. It extends the Possest–PQF model into cosmological and cognitive domains. Volume II of Possest–PQF Ontology of Filtration continues and deepens this conceptual trajectory. It elaborates the recursive operators (\delta^*)^k as the formal mechanism of filtrational bifurcation, reinterpreting structures such as time, irreversibility, and eventhood as local configurations within accessibility fields. Through comparative dialogues with Prigogine’s dissipative systems, Lautman’s mathematical dialectics, and Badiou’s set-theoretic ontology, this volume demonstrates that reality is not composed of entities, but of asymmetric filtrational tensions — diagrammed, reorganized, and collapsed through topological sequences of availability.
