…d Pseudo-Huber smoothness
Output system:
- Satellite-standard L2A naming: S2A_L2A_YYYYMMDDTHHMMSS_T{tile}_{product}.tif
- Auto-generated STAC v1.1.0 Item with eo:bands, projection, view, processing extensions
- Preview PNGs: false-colour composite, AOT/TCWV colour maps, cloud mask overlay, scatter plots
- Reuse resample_mask_to_template from siac.geo.resample (eliminates 85 lines of duplication)
- Extract _write_bands helper in raster writer; partition STAC artifact iteration
Solver:
- Replace DCT-based smoothness with Pseudo-Huber penalty on finite differences
- Edge-preserving: quadratic for small gradients (noise), linear for large (hotspots)
- Add smoothness_delta config parameter threaded from schema through assembly
- apply_smoothness_filter now uses iterative Pseudo-Huber diffusion
- Cap multigrid grid levels at input dimensions; deduplicate collapsed levels
- Post-grid-search spatial smoothing with inflated uncertainty at invalid pixels
