Existence as Fixed Point: A Meta-Theory of Deterministic Collapse

Three companion papers establish a closed triangulation: a formal algebra of collapse-based computation [1], a proof that natural systems satisfy the algebra's preconditions because death provides the exhaustive veto partition [2], and a structural connection between the algebra's fixed-point distinction and seven open mathematical frontiers [3]. This paper presents the meta-theory — the claim that emerges when the three results are read together. The claim is existential: existence itself is the fixed point. Not a property of existence, not something existence has — existence is the collapse to purity, the return to the ground state, the structure that persists when everything else is extinguished. The…
