Changes in version 0.1.0 Development - Fixed active-pencil wavelet round-trips for sparse, non-contiguous masks by lifting compact active runs rather than padded full-grid pencils. - Fixed HRBF tiny-ROI sparse fallback construction for non-contiguous masks. - Clamped inferred temporal Slepian handle ranks to the valid [1, n_time] range. - Preserved one-column matrix shape in decode_coefficients(wrap = "none") when the caller supplied a matrix. - Derived hierarchical-template and spatial PCA component counts from returned eigensolver columns rather than requested ranks. - Guarded bilateral surface wrapping by checking the BilatNeuroSurfaceVector class before construction.
