Abstract

This paper develops a theorem-level trace-connection framework for an internal phase-reorganization interpretation of the three-dimensional incompressible Navier--Stokes equations. Starting from an intrinsic-time reparameterization of a classical solution approaching a candidate singular time, it derives the exact same-PDE intrinsic connection equation, a Bochner state-trace formula, and the induced observable trace law. The paper then gives three deterministic routes for upgrading an L2L2 trace to a strong XmXm trace: dyadic tail-flux decay, Abel-bridge/first-spectral-moment control, and stronger Sobolev bounds. The framework remains entirely inside the original Navier--Stokes variables, with no post-singularity PDE, constitutive switch, or external medium, and it formulates an explicit falsifiability/verification interface for future analysis and numerics.
