Explain the Lean def `gravitationalWaveCert` in module `IndisputableMonolith.Astrophysics.GravitationalWaveFromJCost`. 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 canon source does not contain the module IndisputableMonolith.Astrophysics.GravitationalWaveFromJCost or any declaration named gravitationalWaveCert. No material bearing directly on this specific definition is present. The source instead covers unrelated topics such as dark matter as topological frustration, flyby anomaly explanations via thermal effects, ILG weight kernels in flight-gravity bridges, energy-processing equivalence via J-cost, gravity parameters derived from phi, zero-parameter gravity emergence, quantum gravity approaches, and Bekenstein-Hawking thermodynamics. Because the requested declaration is absent, none of the five requested aspects (plain-English meaning, RS relevance, formal reading, dependencies, or unproved claims) can be addressed from the canon.
