Explain the Lean lemma `Jmetric_one` 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 requested Lean lemma Jmetric_one in module IndisputableMonolith.Cost does not appear in any of the supplied source modules. Modules such as IndisputableMonolith.Mathematics.LanglandsFromRecognitionCost and IndisputableMonolith.Foundation.RecognitionForcing import IndisputableMonolith.Cost and reference related items (e.g., Jcost, Jcost_symm), but the Cost module itself and the declaration Jmetric_one are absent from the provided canon slice. No explanation of the lemma can be derived from the supplied source.
