Explanation of rsSpectrum in IndisputableMonolith.CrossDomain.CardinalitySpectrum

(1) In plain English, rsSpectrum declares a concrete list of 20 natural numbers that the module presents as canonical cardinalities appearing across Recognition Science structures: [2, 3, 4, 5, 6, 7, 8, 10, 12, 15, 16, 25, 45, 64, 70, 125, 216, 256, 360, 3125]. Each entry is witnessed by an explicit decomposition into RS primitives such as spatial dimension 3, configuration dimension 5, the gap value 45, and powers or products thereof.

(2) It matters in Recognition Science because the module's docstring states the structural claim that RS produces a structured numerical spectrum rather than a random one; every listed member admits a decomposition into the small cube-generators {2, 3}, configDim 5, and gap45. This supports the broader thesis that cardinalities in the RS stack are forced by the same primitives that generate dimensions, ticks, and gaps.

(3) The formal statement is the definition def rsSpectrum : List ℕ := [...]. It is read as a fixed, decidable list whose properties are separately proved by decide tactics. Companion theorems establish that the list has length 20, is strictly increasing (pairwise <), and is bounded above by 3125 = Dconfig^5.

(4) Visible dependencies and certificates in the supplied source include the generator definitions Dspatial, Dconfig, gap45, eightTick, cubeFaces together with the equality theorems eightTick_eq, gap45_eq, cubeFaces_eq. The structure CardinalitySpectrumCert and the value cardinalitySpectrumCert bundle the key decompositions (e.g., D_cubed, D_fifth, choose_central, full_turn) plus the spectrum properties into a single certificate with no sorry or axiom.

(5) This declaration does not prove that the listed numbers are exhaustive, that they correspond one-to-one with physical observables, or that they arise from the forcing chain or cost functional equation; it only collects exemplars and verifies their RS-primitive decompositions within this module.

Aspects Recognition does not yet address:

  • Any theorem connecting rsSpectrum members to the forcing chain, J-cost uniqueness, or specific physical observables beyond the module's structural claim.
  • Proofs that these cardinalities are forced by the Law of Logic or appear in other modules such as RealityFromDistinction or RecognitionForcing.
