 - Added an Operational GIS run panel that reuses the selected AOI bbox or active layer bbox and calls the existing persisted `vector_features` bbox selection workflow.
 - Added a visible basemap policy notice when the public OpenStreetMap fallback is active.
 - Added a guided operational workflow that brings query, derived dataset save, GeoJSON export, reference selection, QA/QC run and evidence handoff into the Map workspace.
-- Updated `CHANGELOG.md`, `docs/TODO.md`, `docs/ENVIRONMENT_SPEC.md` and `frontend/README.md`.

 Limitations:
 - The default OpenStreetMap tile service is appropriate for local V1 testing and demos, but production or heavier deployments should set `VITE_MAP_STYLE_URL` to a managed tile/style provider.
