Explain the Lean lemma `Jcost_eq_zero_iff` 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 module IndisputableMonolith.Cost or declaration Jcost_eq_zero_iff. Closest material appears in imported references: IndisputableMonolith.Mathematics.LanglandsFromRecognitionCost uses Jcost_symm in Z_RS_functional_equation, and IndisputableMonolith.Foundation.RecognitionForcing defines recognition_cost via LedgerForcing.J with theorems self_recognition_zero_cost, nontrivial_recognition_positive_cost, and recognition_is_cost_structure establishing zero-cost iff ratio=1. No direct statement of the queried lemma exists.
