Foundation Operator Core Complex Structure Forcing Total Mode Cost

The total mode cost

In the Recognition Science framework, a recognition event is a discrete record of a comparison. The framework's central object is a cost function J(x) = (x + 1/x)/2 - 1, proved unique under five plain conditions. This page concerns a specific declaration, totalModeCost, which sums that cost across the eight ticks of a recognition cycle. The declaration is an abbreviation: it names a pre-existing definition in the framework's ComplexStructureForcing module, so it establishes a naming convention rather than a new mathematical fact.

The eight-tick cycle is the framework's model of a complete recognition event, and the declaration totalModeCost assembles the per-tick costs into one total. The framework's library proves that this total is phase-invariant: shifting the ticks in time does not change the total cost. This is a theorem, not a definitional choice. The proof anchors to the declaration mode_cost_phase_invariant, which in turn rests on the phase invariance of the underlying cost function J. The practical consequence is that the total cost of a recognition event is a stable quantity, independent of when the event starts.

In Recognition Science, the declaration also participates in the framework's account of complex structure. The same module defines an eight-point discrete Fourier transform and its inverse, and proves that the transform preserves the inner product. The total mode cost is the natural companion to this structure: it assigns a scalar to each eight-tick signal, and the phase invariance theorem guarantees that this scalar is well-defined under cyclic shifts. The framework models the eight-tick cycle as the carrier of complex structure, and totalModeCost is the bookkeeping device that tracks its cost.

The declaration does not claim that the total cost has a particular numerical value. It defines a function, not a constant. The framework does not derive the value of totalModeCost from the forcing chain; it only defines it and proves its invariance properties. The value would depend on the specific signal being measured. This is a definitional and structural claim, not an empirical prediction. The framework's library contains no theorem that fixes the total cost to a specific number, and none is claimed here.

The distinction matters because the framework's larger claims are often about forced quantities: the golden ratio, the eight-tick cycle, three spatial dimensions. totalModeCost is not one of those forced quantities. It is a defined tool, useful for bookkeeping, whose key property is its invariance under time shifts. A reader should understand it as a measure, not a law.

What this page does not claim

The declaration does not fix a numerical value for the total cost of any signal. The phase invariance theorem does not imply that the total cost is independent of the signal itself. The framework does not derive totalModeCost from the five conditions that force J(x).

Verify this page

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:

$ lake env lean IndisputableMonolith/Foundation/OperatorCore/ComplexStructureForcing.lean
expected axiom basis: [propext, Classical.choice, Quot.sound] (the Lean kernel's standard three; no RS-specific axioms)

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.
