SΔϕ-11 — World, Other, Self, and Consciousness as Boundary Phenomena: Minimal Re-entry Ontology after SΔϕ-10 (v1.0)

This paper fixes a minimal ontological layer implied by the Sofience–Δϕ (SΔϕ) series after SΔϕ-10. It defines world, other, self, consciousness, and meaning as positions within a single boundary re-entry dynamics: world as persistent Δϕ influx (externality), other as irreducible mismatch under available model updates, self as a folded boundary stabilizing transition continuity, consciousness as boundary-displacement monitoring with write-back into next transition selection, and meaning as the residue of stabilized boundary re-entry. The paper includes the Re-entry Boundary Diagram (RBD) to present the closed loop World → Error → Boundary → Consciousness → Meaning.
