The module defines NumberSystem and NumberSystemCert structures and certifies that positive rationals contain the J-cost domain. Researchers building RS models or the phi-ladder would cite these definitions when selecting a concrete domain. The module consists of type definitions plus one certification statement linking rationals to the J functional equation.

claimA NumberSystem is a domain $D$ equipped with a J-cost function satisfying the Recognition Composition Law. The module certifies that $D = {Q}^+$ (positive rationals) contains the J-cost domain.

background

Recognition Science starts from the J functional equation whose solutions yield the self-similar fixed point phi and the eight-tick octave. This module supplies the first concrete number system by showing that the positive rationals form a valid carrier for the J-cost. It imports Mathlib and introduces the sibling declarations NumberSystem, numberSystemCount, rational_contains_jcost_domain, NumberSystemCert and numberSystemCert.

proof idea

This is a definition module, no proofs.

why it matters in Recognition Science

The module supplies the rational carrier used by later constructions of the phi-ladder and mass formulas. It directly supports the J-uniqueness step (T5) in the forcing chain by exhibiting an explicit domain closed under the required operations.
