# SuperfluidSemanticKernel
A minimal Lean-side receipt kernel for the Newtonian Superfluid Simulation adapter.
This is not a proof that the simulation is a literal physical superfluid or that
semantic mass is SI mass. It provides a fixed-point, finite-state gate for the
custom semantic-mass stack.

/--
A conservative route-admissibility gate.
The state can route only if semantic mass and basin strength outweigh unresolved
torsion, while still requiring receipts for V-scope promotion elsewhere.
