JensenSketch module sketches Jensen inequality for the J-cost function. Researchers deriving cost bounds in Recognition Science cite it for convexity arguments. It imports the Cost module and contains sketch definitions without full proofs.

claim$J(\mathbb{E}[X]) \le \mathbb{E}[J(X)]$ where $J(x) = \frac{x + x^{-1}}{2} - 1$.

background

This module is part of the Cost domain in Recognition Science. It builds on the J-cost introduced in the imported IndisputableMonolith.Cost module. The J function satisfies the Recognition Composition Law and is the fixed point in the forcing chain T5.

proof idea

This is a definition module, no proofs.

why it matters in Recognition Science

The module supports development of cost inequalities that feed into mass formula derivations and phi-ladder calculations on the eight-tick octave. It relates to T5 J-uniqueness and T6 phi fixed point in the UnifiedForcingChain.
