Foundation Pair Kernel Gap2a Real Cotangent Normalization Residual Unique Cotang

The unique cotangent coordinate

In the Recognition Science framework, a ledger (a discrete record of events) carries a rank-one posting lattice, and that lattice has a unique positive primitive integer character. The framework's native action quantum prices a canonical embedding of that lattice into the real numbers. The declaration uniqueCotangentCoordinate_eq_nativeActionQuantumInv proves that the unique real-linear functional extending that character along the action-priced embedding has a coordinate equal to the reciprocal of the action quantum. In plainer terms: the one and only linear map that respects the lattice's structure and its pricing is multiplication by the inverse of the action quantum.

This uniqueness is theorem-backed. The framework's machine-checked library of formal theorems proves that any real-linear functional extending the primitive character along the action embedding must equal the canonical one, and that its coordinate is exactly nativeActionQuantumInv. The same library proves that this coordinate is distinct from the exact-J variational conjugate, so the first variation of the cost function does not supply the identification. The theorem also establishes that adjoining this uniqueness package to the current recognition source premises still admits two distinct candidate source scales, so the package does not select a unique physical scale.

What the declaration does not claim is the physical identification. The theorem does not prove that the unique cotangent coordinate is the source scale of the physical pair-kernel. That identification is definitionally equivalent to a separate law, NativeActionDualSourceLaw / Bridge 1, and the library explicitly proves it is not forced by the uniqueness package. A missing physical premise, UniqueCotangentNormalizationByActionUnit, remains open: an independently physical law that identifies the unique character-extension cotangent with the pair-kernel source without inserting the identification as a definition and without Green aggregation.

The practical consequence is a clean boundary. The framework proves a mathematical uniqueness statement about a cotangent coordinate, but the step from that coordinate to a physical source scale is a definitional choice, not a theorem. The two candidate scales admitted by the current premises remain distinct, and the identification with the cotangent coordinate selects one of them, candidate B. The exact-J conjugate is a different real number, so no variational argument closes the gap. The recognition source premises plus the uniqueness package do not yet force the physical law; that remains a target.

What this page does not claim

The theorem does not prove that the unique cotangent coordinate is the physical source scale. The theorem does not derive the fine-structure constant or any other coupling constant. The theorem does not establish the Riemann Hypothesis or any other unproved number-theoretic statement.

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:

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.
