Explain the Lean lemma `Jlog_as_cosh` 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 Jlog_as_cosh. Modules such as IndisputableMonolith.Mathematics.LanglandsFromRecognitionCost and IndisputableMonolith.Unification.RecognitionBandwidth import IndisputableMonolith.Cost, but the actual definitions, lemmas, or statements from that module are absent. No theorem or lemma named Jlog_as_cosh appears verbatim in any provided file. The question cannot be answered from the canon slice.
