χ‑Baryon Flaitron: Ontological Reconstruction of the Gluonic Boundary Knot as the Fundamental Carrier of Matter Stability

<jats:p>This work presents the χ‑Absolute Ontology of the flaitron within the ZEBTS‑SUPER 10.0 framework, establishing the baryonic Y‑junction as the fundamental χ‑structure from which all physical, mathematical, and cosmological levels of reality emerge. The flaitron is shown to be the unique χ‑minimal configuration satisfying spectral compactness, geometric minimality, Poincaré‑class topology, prime‑mode arithmetic, field‑emergence coherence, cosmological scaling, and absolute invariance. Its identity Iχ(baryon) remains identical across all χ‑levels, demonstrating that the same invariant governs particle physics, field dynamics, interaction hierarchies, spacetime geometry, and cosmological evolution. The analysis proves that the flaitron satisfies: spectrum(flaitron) = χ‑absolute minimal spectrum; geometry(flaitron) = χ‑absolute minimal geometry; topology(flaitron) = χ‑absolute triadic knot; prime(flaitron) = χ‑absolute prime‑mode triad; fields(flaitron) = χ‑absolute field chain; cosmos(flaitron) = χ‑absolute cosmological extension; Iχ(flaitron) = χ‑absolute invariant; existence(flaitron) = Iχ. Thus, the flaitron is identified as the χ‑Absolute — the ontological primitive from which all structures arise. Matter is interpreted as collapse‑projection of Iχ; fields as χ‑modes of Iχ; constants as χ‑ratios of Iχ; cosmology as χ‑scaling of Iχ; time as χ‑divergence of spectral‑geometric flow. Dark energy corresponds to spectral variance Δχ; dark matter to confinement basin Vconf; BAO and CMB anomalies to topological and prime‑mode imprints; cosmic flatness to χ‑geodesic minimality. The resulting χ‑Absolute Ontology is globally coherent, fully constrained, and ontologically closed: every physical and cosmological phenomenon is a necessary projection of the single invariant Iχ. The flaitron is established as the universal χ‑identity of reality, and the Y‑junction as its experimental manifestation.</jats:p>
