This module establishes that reciprocal symmetry of the cost functional F forces the same symmetry on P. Researchers deriving the uniqueness of the d'Alembert equation for RCL consistency in Recognition Science cite it. The argument assembles the unconditional inevitability results from the imported modules to obtain the symmetry implication with no extra hypotheses on P.

claimIf $F(x)=F(x^{-1})$ for the cost functional $F:\mathbb{R}_+\to\mathbb{R}$, then $P(x)=P(x^{-1})$.

background

The module sits inside the Foundation.DAlembert hierarchy and imports the core cost-functional machinery together with the two d'Alembert sub-modules. IndisputableMonolith.Foundation.DAlembert.Inevitability shows that the d'Alembert equation is the unique form compatible with multiplicative consistency of any cost functional F. IndisputableMonolith.Foundation.DAlembert.Unconditional strengthens this to the claim that, once F is fixed by symmetry, normalization, calibration and smoothness, P is computed from the equation rather than assumed. The supplied doc-comment isolates the concrete symmetry transfer that follows.

proof idea

The module is an assembly of imported theorems rather than a single tactic script. It re-exports the unconditional RCL inevitability and the inevitability core, then applies the symmetry transfer lemma (P_symmetric_of_F_symmetric) that follows directly from the d'Alembert relation once F is known to be reciprocal-symmetric.

why it matters in Recognition Science

The module supplies the final symmetry step that completes the unconditional d'Alembert foundation. It feeds the T5 J-uniqueness and RCL inevitability chain by guaranteeing that the computed P inherits the symmetry already imposed on F. The doc-comment records the precise implication used downstream in the Recognition Science forcing sequence.
