Explain the Lean class `JensenSketch` 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 Lean source modules do not contain any declaration or definition of the class JensenSketch (or any class by that name) in module IndisputableMonolith.Cost or its submodules. The name appears only once, in a docstring comment within IndisputableMonolith.Cost.AczelClassification describing it as a 'compatibility layer' that is no longer the official route. No formal statement, fields, or instances are present. Therefore no explanation of its declaration, dependencies, or proofs can be produced from the canon.
