fix: preserve official Mol CRS provenance

 - Kept the provider boundary honest: provisioning is an operator action and
   imports through canonical Project, Area and Dataset HTTP routes. It does not
   enable the dormant live GRB provider or write directly to `vector_features`.

+- Pushed and deployed commit `490325e`; live PostGIS `3.6`, required
+  schema/indexes, Alembic head, frontend proxy, API proxy and icon checks
+  passed.
+- Provisioned project `143dee9a-b279-4984-9d30-1687fac3efcc` and official
+  area `3166ef08-3b40-410a-a6c0-0b854186e557` with bounds
+  `[5.035357, 51.1534809, 5.24218961, 51.32265943]` and projected area
+  `114.546677 km2`.
+- The complete source bbox returned `89,153` unique GRB candidates over `90`
+  pages. Exact municipality clipping retained `36,941` buildings, rejected
+  `52,212` outside features and clipped `24` boundary-crossing features. The
+  manifest is complete and explicitly reports `reference_truncated=false`.
+- PostGIS contains `36,941` vector feature rows and `36,941` distinct source
+  IDs, with zero invalid geometries and zero non-EPSG:4326 geometries. Strict
+  coverage reports 18 floating-point boundary artefacts whose combined
+  outside area is only `5.75e-9 m2`; no material building area falls outside
+  Mol.
+- A fresh browser session selected the municipality project, official area
+  and one-feature boundary automatically instead of a historical Postel
+  validation context. Selecting the complete building layer rendered all
+  `36,941` features and a live AOI PostGIS query returned `250` persisted
+  features with dataset/export actions enabled.
+- Browser verification at `1280x720` and `2560x1080` found one nonblank
+  MapLibre canvas, no console warnings/errors and no horizontal overflow. The
+  widescreen map canvas measured `1678x734` CSS pixels.

 ## Next pass
 
-- Deploy and execute the explicit provisioner on Tower, verify full PostGIS
-  feature counts and exact Mol bounds, then audit the complete municipality in
-  MapLibre before acquiring raster imagery for a deliberately selected Mol
-  analysis zone.
+- Add viewport/zoom-aware vector delivery before expanding beyond Mol or
+  layering additional municipality-wide reference classes. Then acquire and
+  tile georeferenced imagery only for an explicitly selected Mol analysis zone
+  and run configured-YOLO plus QA/QC against the persisted GRB reference.
