Foundation Dalembert Unconditional

Unconditional RCL Inevitability

Foundation dalembert unconditional is the strongest form of a central result in Recognition Science: the rule by which two recognition costs combine is forced by the cost function itself. The module proves that no assumption on the combining rule is needed. If the cost function F is symmetric, normalized, calibrated, and smooth, and if it satisfies a consistency equation with some combining rule P, then both F and P are uniquely determined. The cost function is forced to be J(x) = (x + 1/x)/2 - 1, and the combining rule is forced to be P(u, v) = 2uv + 2u + 2v.

The key insight is that P is computed, not assumed. Earlier versions of the result required P to be a polynomial, which left open the possibility of irregular solutions. This module removes that restriction entirely. The proof works by first showing that J itself satisfies the consistency equation with the explicit form of P. Then, since J maps positive numbers onto all nonnegative values, any P that satisfies the equation with J must agree with that explicit form on the entire first quadrant. The theorem rcl_unconditional states this directly: if any P satisfies the consistency equation with J, then P(u, v) = 2uv + 2u + 2v for all nonnegative u and v.

A further uniqueness theorem shows that any two functions P and Q satisfying the equation with J must be equal on the nonnegative quadrant. This rules out all alternatives, polynomial or not. The module also assembles the complete forcing chain: F is forced to be J, J satisfies the cosh-add identity, and the multiplicative form is the recognition cost law. The consequence is that the structure of Recognition Science is closed at this point: the cost function and its combining rule are locked together, with no free parameter left in the consistency equation.

What this page does not claim

This answer does not claim that the cost function J itself is derived in this module, only that the combining rule is forced given J. This answer does not claim that any physical constants or dimensions are derived here. This answer does not claim that the proof of J's uniqueness from symmetry, normalization, calibration, and smoothness is contained in this module.

Every tagged claim above names its theorem. To check one yourself rather than trust this page, elaborate the source module with Lean 4 and audit its axiom basis:

A page whose claims cannot be reproduced this way does not ship. In production, every anchor links to the exact declaration in the public source release, and this block carries the build receipt for the page itself.
