Explain the Lean lemma `Jlog_nonneg` in module `IndisputableMonolith.Cost`. Write for an educated reader who knows science and programming but may not know Lean. Cover: (1) what the declaration says in plain English, (2) why it matters in Recognition Science, (3) how to read the formal statement, (4) visible dependencies or certificates in the supplied source, and (5) what this declaration does not prove. Cite only declarations present in the supplied Recognition source.

The supplied Lean source does not contain the module IndisputableMonolith.Cost or any declaration named Jlog_nonneg. The provided modules are: IndisputableMonolith.Foundation.AlexanderDuality (defines CircleReducedCohomologyNontrivial, alexander_duality_circle_linking), IndisputableMonolith.Mathematics.LanglandsFromRecognitionCost (defines Z_RS, Z_RS_functional_equation, langlandsCert), IndisputableMonolith.Foundation.RealityFromDistinction (defines reality_from_one_distinction, RealityCertificate), IndisputableMonolith.Measurement.RSNative.Calibration.SingleAnchor (defines externalCalibration_of_tau0_seconds, tau0_seconds_protocol), IndisputableMonolith.Unification.RecognitionBandGeometry (defines rhoBandLower, bandBoundaries_sum_to_one), IndisputableMonolith.Unification.RecognitionBandwidth (defines bandwidth, IsSaturated), IndisputableMonolith.Foundation.RecognitionForcing (defines recognition_cost, recognition_forcing_complete), and IndisputableMonolith.Meta.ConstructiveNote (defines Computable, pi_computable). No J-cost non-negativity lemma or log-related cost statement appears. The question therefore cannot be answered from this canon slice.

Aspects Recognition does not yet address:

  • The declaration Jlog_nonneg in module IndisputableMonolith.Cost
  • Any formal statement or proof of non-negativity for a logarithmic cost function
  • Dependencies or certificates specific to the Cost module
