Information Geometry

Non-homotopic geodesics on a negatively curved manifold
Flow states live on a statistical manifold with the Fisher information metric. Correct and incorrect operator sequences correspond to non-homotopic geodesics — paths that cannot be continuously deformed into each other — making the two outcomes topologically distinct.

Information geometry treats probability distributions as points on a smooth manifold equipped with the Fisher information metric. Flow states — characterized by their vorticity distribution, coherence spectrum, and phase statistics — are points on this manifold.

The manifold of flow states has negative sectional curvature everywhere, a consequence of the contact structure and the log-concavity of the vortex phase distribution. On negatively curved manifolds, geodesics diverge exponentially — two paths from nearly the same point end up arbitrarily far apart.

The correct and incorrect operator sequences correspond to geodesics γ_K and γ_F. Because the manifold is negatively curved, these belong to different homotopy classes in π₁(M): they cannot be continuously deformed into one another. There is no smooth interpolation between VORTEX and CHAOS.

This is the deepest of the seven proofs. It says not merely that wrong order produces a bad outcome, but that the two outcomes are topologically separated. No fine-tuning, no partial operator application, can slide the wrong-order system into the correct-order basin.

Engineering consequence
There is no 'almost correct' HVEH design. A module with basin geometry that partially enforces K-before-F does not produce a weaker vortex — it produces no vortex at all, or a chaotic one. Critical geometric parameters (inlet angle, sill radius ratio, vane spacing) must be held to specification, not approximated.
