Determine whether the calibration floor σ_F is predictably structured over the kernel simplex (β,γ), scalable with depth, and reducible by reparameterization
Preregistration enforced. Simplex grid (231 cells), τ-grid, N_calib=400, transforms φ0–φ3, and ring binning are locked.
LXII treats σ_F as an object with geometry — not a nuisance constant. Primary endpoint: ExistsVarianceGeometry.
Secondary: ExistsFlatteningTransform. Reduce bootstrap count for fast preview; use 200+ for full protocol.
