Explain the Lean def `Jcost` 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 canon source does not contain the module IndisputableMonolith.Cost or any declaration named Jcost. Several modules import IndisputableMonolith.Cost (e.g., IndisputableMonolith.Mathematics.LanglandsFromRecognitionCost, IndisputableMonolith.Geology.VolcanicForcingAsJCostImpulse) and reference related items such as Jcost_symm, Jcost_nonneg, Jcost_unit0, and Jcost_eq_sq, but the core definition is absent from the provided source. No explanation of the Lean def Jcost can be given from the canon as supplied.
