ChokePoint
The ChokePoint structure records a named bottleneck where an alternative framework could evade the inevitability argument unless a proof closes it. Researchers organizing the case that any zero-parameter theory must reduce to Recognition Science cite these records to track which necessities remain open. The declaration is a bare structure definition whose three string fields hold an identifier, a status label, and a one-sentence statement of the claim that closure would establish.
claimA choke point is a record whose fields are a name (string), a status string taking values in the set {closed, scaffold, open}, and a consequence string that states the physical theorem established once the point is closed.
background
The InevitabilityStructure module formalizes the claim that moving the foundation to cost minimization relocates degrees of freedom into three buckets: uniqueness of the cost function J, the meaning of existence as defect reduction, and the admissible class of zero-parameter frameworks. Under this view any alternative must break one of six listed necessities, of which the first is cost uniqueness (T5) and the last is dimension forcing to D = 3. Upstream structures supply the supporting data: RSNativeUnits.status records the native units with ħ = φ^{-5} and the φ-ladder; LedgerFactorization.of and PhiForcingDerived.of encode the calibration of J on (ℝ₊, ×); SpectralEmergence.of and PhysicsComplexityStructure.of supply the discrete tier counts and convexity of J.
proof idea
The declaration is a structure definition that introduces the ChokePoint type with three fields; no tactics or lemmas are applied.
why it matters in Recognition Science
ChokePoint supplies the data type used by all_choke_points to enumerate the four bottlenecks and by the four named instances (choke_universality, choke_cost_axioms, choke_exclusivity, choke_dimension) that track progress toward the Inevitability Theorem. It directly organizes the argument that alternatives must violate cost uniqueness (T5), the CPM selection rule, discreteness, ledger structure, self-similarity forcing φ, or the D = 3 requirement. The definition leaves the scaffolded points (dimension forcing and framework exclusivity) explicitly open.
scope and limits
- Does not prove any listed choke point closed.
- Does not encode the mathematical statement of cost uniqueness or dimension forcing.
- Does not restrict the status field to a finite enumerated type.
- Does not derive the Recognition Composition Law or the value of φ.
