If you need...	Use	Why
Prioritized review queue for known/suspected construction	run_senbygg_improved.py	Candidate-first avoids whole-AOI base-rate false positives.
Raster anomaly map for a small AOI	bbox_change_detector.py	Gives GeoTIFF score/change-date layers for inspection.
Coherence recall boost	download_coherence*.py + senbygg_coh.py	Detects hard-target stabilization missed by GRD intensity.
Optical confirmation	download_s2_summer.py / s2_aoi_indices.py + senbygg_s2.py	Detects vegetation-to-built summer index changes.
Method comparison	fkb_tiltak_cusum.py, validation/	Experimental CUSUM and validation sweeps.
