This formal theorem excludes a global smooth uniformly bounded-energy solution. It is kept separate from the stronger compact-data finite-lifespan theorem, so the former is not used alone to claim all of the latter’s details.

Complete formal proof reported externally
This formal theorem supplies compact support, a maximal lifespan 0 < T* ≤ 1 in the all-order Sobolev class, bounded energy before breakdown, infinite C¹ limsup and divergent integrated vorticity. The project reports only standard logical axioms and self-assessed correspondence. It is not an OpenMath execution.

Exact periodic nonexistence theorem for every positive viscosity. The reference definitions and independent execution are separate checks; no unforced theorem is linked to this declaration.

Complete formal proof reported externally
The formal theorem matches official alternative C with explicit decay/force and energy assumptions. The stronger from-rest compact singular-flow statement is separate and has no complete formalization asserted by this link. Metadata reports zero sorry and standard logical axioms only.
