The Uniqueness of the Phenomenology Framework Uniqueness, Categoricity, and Survivor Selection for Closure-Compatible Phenomenology

Paper 74 constructed a formal phenomenology framework based on a six-part ontology \Ont = (\OntM, \OntR, \OntP, \OntJ, \OntL, \OntA), manifestation structure, ownership, locus, selector-access regimes, anti-collapse theorems, and rival-formalism exclusion results. It did not claim uniqueness. The present paper develops the corresponding uniqueness program—a theory-selection program in which the Paper 74 framework is one candidate among admissible candidates, not a coronation. We use the necessary ontological ground theorem (Papers 61–63 ) as the first admissibility sieve: any theory lacking a necessary ground or ground-equivalent structure is inadmissible. This drastically shrinks the viable theory-space; within that space, further collapse and reconstruction test whether the Paper 74 framework is uniquely selected up to \sim. We establish a self-risk rule and anti-gerrymander discipline. We stratify the uniqueness program (ground sieve \to among ground-admitting survivors \to reconstruction), require a weaker-start reconstruction path, and define tiered success burdens (S1/S2/S3). Paper 75 imports theorems from Papers 61–63, 73, 74—it does not re-prove them. The result: any theory that tries to model the phenomenon seriously is driven toward necessary ground; and once there, collapse routes force progressively more of the six-part structure. Within the formal admissible theory-space \mathfrakT—whose conditions are earned and which exposes the Paper 74 framework to failure—the Paper 74 framework is the uniquely selected survivor up to equivalence. Uniqueness is proved over the admissible theory-space (\mathfrakT), up to the paper's explicit theory-equivalence relation (\sim). All flagship theorems are machine-checked (phenomenology-lean, 8092 jobs, 0 sorry). This overview presents the core NEMS theorem engine and selected applications; stronger domain-specific derivation and ontological synthesis claims belong to separate release surfaces with their own premise bundles and formal artifacts. Trust boundary. The formal result is \textbfuniqueness within \mathfrakT up to \sim, not casual elimination of every informal philosophy of mind.
