 ## Implementation order
 
-1. Operate and validate the Mol VHA profile Dataset and map flow.
-2. Add VHA municipal partition orchestration for Flanders.
+1. Operate and validate the Mol VHA profile Dataset and map flow. **Done.**
+2. Add VHA municipal partition orchestration for Flanders. **Implemented;
+   complete live provisioning remains an explicit operator run.**
 3. Implement a bounded MDK WCS probe, then acquisition behind live evidence.
+   **Probe implemented. Acquisition blocked because the live endpoint fails
+   strict hostname validation and does not expose usable capabilities.**
 4. Implement SPW download staging and vertical-datum metadata validation.
 5. Add maritime boundaries as separate authoritative scope layers.
 6. Add cross-source vertical-datum transformation only with authoritative
    grids/parameters and uncertainty tests.
 7. Add volume only after a compatible measured or modeled water-surface source
    is part of the same analysis contract.

+The Flanders scope is land-only and is dynamically derived from the complete
+current VRBG municipality collection (285 members at the 2026-07-17
+validation). Belgium is not represented by expanding that polygon. Wallonia,
+Brussels, the territorial sea and the Belgian EEZ/continental shelf require
+their own authoritative adapters and legal scope labels.
