Why the power is five

In the framework's derivation of the fine-structure constant, a curvature correction term appears with a denominator of 102π⁵. The natural question is why the exponent is 5 and not 3, 4, or 6. The declaration curvature_power_family_eq_canonical_iff answers this by stating an equivalence: the expression −103/(102π^d) equals the canonical value −103/(102π⁵) if and only if d = 5. In plain terms, the only power of π that reproduces the correction is the fifth power.

The proof is a direct consequence of the fact that π is greater than 1. The library shows this by taking logarithms: if π^d = π⁵, then d·log(π) = 5·log(π), and since log(π) is positive, d must equal 5. This is the kind of elementary argument that a machine can check completely. The theorem also has two companion results: the numerator must be 103 and the denominator must be 102 for the expression to match the canonical form, so the entire triple (d, k, n) is uniquely pinned down.

Why is the dimension 5 in the first place? The framework models the ledger, a discrete record of recognition events, as living in a configuration space with five effective dimensions: three spatial dimensions from the forced D=3, one temporal dimension from the eight-tick cycle, and one balance dimension from a conservation constraint. Each dimension contributes a factor of π from angular integration, so the product is π⁵. The declaration config_space_is_5D states this directly, and config_space_complete verifies that 3 + 1 + 1 = 5.

What the declaration does not claim is that the fine-structure constant itself is derived. The curvature correction is one term in a larger expression for α⁻¹, and the seed 44π is an identification, not a derived coupling. The theorem only establishes the uniqueness of the exponent within this specific correction term. It also does not assert that the configuration space is physically real; it is a model choice within the framework. The declaration is a statement about the internal consistency of the derivation, not a measurement or a prediction.

What this page does not claim

The fine-structure constant α itself is derived from this declaration. The configuration space is physically real rather than a modeling choice. The theorem applies to any expression other than the specific curvature correction term.

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/Constants/CurvatureSpaceDerivation.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.
