📘 Papers #200–#201 Released: Unified Prelude: From Constitutional Geometry to Metric Realization Boundary (NDG–NEPG Structural Integration)

Today we publicly release the integrated formulation of two structurally distinct yet continuous works within Ken Nakashima Theory™:

Nakashima Dynamic Geometry (NDG, #200) and
Nakashima Execution–Persistence Gravity (NEPG, #201).

#201 Nakashima Execution–Persistence Gravity: A Conservative Source-Gated Extension of General Relativity

#200 Nakashima Dynamic Geometry (NDG):Principia of Recognition, Extension, and Geometric Continuity under Admissible Structure

Paper #200 establishes the minimal admissible geometric constitution independent of metric realization.
Paper #201 defines the precise condition under which curvature acquires execution-phase contributions in Lorentzian spacetime.

Together they define a layered structure:

Geometric generation precedes metric realization;
metric activation is conditionally admitted.


The Role of NDG (#200)

NDG defines geometry not as metric data, but as admissible structure generated by four independent axioms:

  • Boundary-condition irreversibility

  • Non-commutative transport

  • Two-sided global admissibility

  • Symmetry-projected quotient economy

Metric structure appears only through the projection functor

Π_metric : G_NDG → Met(M),

which is non-invertible. Its kernel defines the Recognition Barrier.

Metric curvature is therefore a shadow of prior admissible geometry.


The Role of NEPG (#201)

NDG fixes geometric constitution but does not determine when additional curvature sourcing becomes relevant.

NEPG introduces the invariant persistence ratio I and defines the activation hypersurface

Σ := { I = 1 }.

  • For I ≤ 1: β(I) ≡ 0
    → Field equations reduce identically to General Relativity.

  • For I > 1: bounded execution-phase contributions β(I)Ξ_{μν} enter with quadratic onset.

Crucially:

  • The Einstein principal symbol is unchanged.

  • No δ-supported curvature layer arises.

  • Hyperbolicity and ADM constraints are preserved.

This is not a modification of GR in its principal structure, but a boundary analysis of its admissible source sector.


Mathematical Status

  • No additional dynamical metric field is introduced.

  • No higher-order derivatives appear.

  • Sobolev regularity and Geroch–Traschen compatibility are satisfied.

  • Weak Bianchi identity holds across Σ.

The extension is conservative and source-gated.


Empirical Perspective

All currently accessible gravitational regimes lie within the protected basin I ≤ 1.

Activation, if realized, appears quadratically in (I−1).

The theory remains falsifiable without contradicting precision gravitational tests.


Closing Note

NDG fixes geometric constitution.
NEPG fixes the metric realization boundary.

This integration is not an expansion but a stabilization of structure.

Future work proceeds through candidate activation windows and empirical horizon exploration.
