}

The exact, image-frozen conformal-boost flow reparameterization of one d = 2 sphere atom: the canonical per-row (lat, lon) and the exactly recomposed decoder.

Fields

new_row_coords: Array2<f64>

Canonical per-row coordinates t̃_i = φ_θ(t_i), shape (n, 2).

new_decoder: Array2<f64>

Recomposed decoder B̃ = T · B, shape (m, p) — the exact LS refit of the original decoded image on the audit grid against the basis at the transported grid (so γ̃ = γ ∘ φ⁻¹ without ever forming φ⁻¹).

decoder_transport: Array2<f64>

The (m, m) basis transport T with Φ(φ(u)) · T ≈ Φ(u) on the audit grid — the congruence object the smoothness Gram is transported by.

flow_theta: Vec<f64>

Optimal boost coefficients θ (layout [Z, X, Y]).

defect_initial: f64

Round-sphere isometry defect E(0) of the fitted chart (identity flow).

defect_final: f64

Round-sphere isometry defect E(θ) of the canonical chart. Strictly below defect_initial (the pass refuses no-improvement flows).

min_flow_jacobian_det: f64

min det Dφ_θ on the band guard grid. Always > SPHERE_FLOW_DIFFEO_MIN_DET when Some(..) is returned.

recomposition_residual: f64

Max-abs recomposition error on the audit grid, relative to the image scale. Always ≤ CHART_RECOMPOSITION_REL_TOL when Some(..).
