-The persisted `Kempen Regional Workbench` is the automatic operational data context. Its datasets are loaded once for the complete official 28-municipality Vlaamse vervoerregio; the operator chooses Mol, another municipality or the complete region as a spatial work-area filter. The primary map no longer asks the user to choose a technical project or region before data becomes usable. Regional population and modern forest snapshots use the same current/evolution flow as Mol, while explicit project selection stays available under advanced management.
+The persisted `Belgium and North Sea Workbench` is the unconditional primary
+data context whenever it exists. The map opens at national extent and supports
+bounded selections across Flanders, Wallonia, Brussels and the legally labelled
+Belgian maritime zones. Mol and the Kempen remain selectable golden regression
+areas, but are never used as an implicit product boundary or startup fallback.
 
 The Status workspace includes one compact `Actualiteit en versiecontrole`

 The user-facing shell is task based: `Kaart`, `Bronnen`, `Kwaliteit`, `Beeldanalyse`, `Downloads`, `Status` and `Beheer`. Internal benchmark projects, raw dataset metadata, provider capabilities, model registry details and QA evidence remain accessible through labelled advanced disclosures instead of competing with the normal workflow.
 
-Detection defaults to the configured local YOLO asset and automatically selects an available raster and active model asset where possible. The model registry and preflight remain honest when PyTorch, Ultralytics, a local model file or a tile manifest is unavailable. The active building profile is operational but remains review-required: its current coverage-aligned benchmark is approximately precision 0.614, recall 0.606 and F1 0.607 over seven positive AOIs, with zero detections in all three pure-empty controls. A reviewed challenger remains inactive because it produced two detections in empty Postel forest.
+Detection defaults to the explicitly configured local YOLO asset and
+automatically selects an available raster where possible. In production the
+asset catalog exposes only the file matching `YOLO_MODEL_PATH`; training,
+partial and smoke checkpoints remain on disk but do not become end-user model
+choices. The current building benchmark covers seven Mol/Kempen AOIs and is
+shown as local validation, not as proof of national model quality. Every other
+Belgian or maritime context requires local reference QA before release.
 
 Map-driven building analysis uses the documented footprint-IoU `0.25` and
 distinguishes model candidates from verified buildings. It shows persisted
