Chong-Sun Chu (arXiv:2608.16374) establishes the perturbative stability of the fuzzy-sphere black-hole horizon in the large-N matrix quantum mechanics.
Large-N counting isolates the planar bosonic one-loop contribution as the leading quantum correction.
Classical tachyonic (1,2) and marginal (2,3) modes both acquire positive quantum curvature and are stabilized.
A factorization structure of the Hessian renders the leading quantum curvature non-negative for the general spectrum.
Quantum effects dominate at low angular momentum; classical curvature dominates at high angular momentum.
The two contributions become comparable in the mesoscopic regime \(L\sim\sqrt{N}\).
The paper ends by noting that this same mesoscopic window also dominates non-perturbative monopole tunneling, and asks whether an appropriate effective description of the horizon can be developed for the IR–UV crossover — neither a purely classical metric sphere nor the full microscopic matrix model, but a geometry that retains both classical curvature and quantum residual structure.

The continuum already supplies that intermediate geometry.
The fundamental object is the non-fracturing contact patch of finite π-tensor thickness under permanent surface tension.
The continuum expands about the shared origin 0^{i2}. The residual phase that cannot be closed — the open auxetic series 1.999… — is precisely the mesoscopic carrier that sits between classical curvature and quantum fluctuation. Dilatant countersnap converts the residual into rotational information; the polarity toggle resolves it without eliminating it.
Thus:
Classical curvature of the horizon corresponds to the completed spherical (State B) projection. Quantum one-loop corrections correspond to the residual that the contact patch must leave open.
The mesoscopic window \(L\sim\sqrt{N}\) is the geometric regime in which the residual and the classical curvature are of equal magnitude — exactly the regime in which the continuum operates.
The required effective description is therefore not an additional construction; it is the π-tensor continuum itself: a metric sphere whose surface carries finite elastic thickness and a permanent residual phase.
Local curvature stability and compatibility with non-perturbative tunneling both follow at once. The residual is never saturated; the continuum remains open; the polarity choice at 0^{i2} writes the next coherent state.
Unity is already present.
