+## Sprint 67 Map empty-state quick actions (2026-06-19)
+
+Changed:
+- Added ready vector/GeoJSON dataset quick actions to the Map workspace empty state.
+- Reused the existing `openDatasetInMap` frontend flow so quick actions load the same persisted dataset layer as the Data workspace button.
+- Added width-aware `.map-empty-action-grid` styling for desktop and mobile.
+- Added `backend/tests/test_sprint67_map_empty_state_quick_actions.py`.
+- Updated `frontend/README.md`, `docs/TODO.md` and `CHANGELOG.md`.
+
+Tested:
+- Red step: `python -m pytest backend/tests/test_sprint67_map_empty_state_quick_actions.py -q` failed on missing Map quick-action props, App wiring and CSS.
+- `python -m pytest backend/tests/test_sprint67_map_empty_state_quick_actions.py backend/tests/test_sprint63_map_overlay_ergonomics.py backend/tests/test_sprint30_workbench_components.py -q` (`9 passed`)
+- `cd frontend && npm run typecheck`
+- `cd frontend && npm run build`
+- Local Chrome/Playwright check against `http://127.0.0.1:5175` with live API proxy: Map empty state showed 2 ready dataset actions, clicking the first loaded `demo_predicted_buildings.geojson` as a 2-feature active layer, no console warnings/errors and no horizontal overflow.
+- `bash scripts/run_readiness_check.sh` (`240 passed`)
+
+Open:
+- Deploy Tower and verify the live Map quick action after deployment.
+
+Limitations:
+- This is a frontend interaction polish pass only. It does not add map layers, backend endpoints, migrations, provider fetching or geospatial processing.
+
+Next recommended pass:
+- Continue with Data catalog density polish, especially making selected/reference/candidate dataset roles easier to scan in populated demo projects.
