Explain the Lean lemma `Jcost_exp` 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 source does not contain the module IndisputableMonolith.Cost or the declaration Jcost_exp. Imports of Cost appear in LanglandsFromRecognitionCost and RecognitionBandwidth, where Jcost is referenced in partition functions and bandwidth formulas, but no lemma named Jcost_exp is defined or proved. The question asks for an explanation of a specific declaration absent from the provided modules.
