ExclusivityCert
plain-language theorem explainer
ExclusivityCert packages a non-circular derivation of the Recognition Composition Law from four minimal constraints on any zero-parameter framework. Researchers establishing uniqueness of Recognition Science would cite this structure when closing the gap between general assumptions and the specific cost function. The definition directly bundles a complete four-step RCL chain with the uniqueness of a non-negative J satisfying J(1)=0 under the constraints.
Claim. An ExclusivityCert consists of a nonempty RCLDerivation chain together with the assertion that every set of constraints satisfying non-static dynamics, zero free parameters, derivation of observables, and self-similarity admits a cost function $J : (0,∞) → ℝ$ with $J(x) ≥ 0$ for all $x > 0$ and $J(1) = 0$.
background
ExclusivityConstraints is the structure whose fields are the four propositions non_static, zero_parameters, derives_observables, and self_similar, with all_hold their conjunction. RCLDerivation is the structure whose fields step1_universal_cost, step2_dalembert, step3_unique_J, and step4_forces_RS are linked by the implication chain_complete. The module addresses the non-circular derivation of the Recognition Composition Law from these constraints alone, avoiding pre-loaded conclusions in prior uniqueness arguments.
proof idea
ExclusivityCert is introduced directly as a structure definition with two fields. The first field requires a nonempty RCLDerivation whose chain_complete witnesses the four-step derivation. The second field asserts existence of the required cost function J under the all_hold predicate from ExclusivityConstraints.
why it matters
This structure is used by the downstream theorem exclusivity_cert_exists, which constructs an instance via rcl_chain_is_valid and constraints_determine_cost. It supplies the non-circular version of the NoAlternatives argument in the Recognition Science framework, linking the four constraints to the Recognition Composition Law and the forcing chain T0–T8. It touches the open question of whether RS is the unique zero-parameter framework without circular assumptions.
