 Validation:
 - RED: `python -m pytest backend\tests\test_sprint105_map_feature_extract.py -q` failed before implementation because the extract panel, selected-feature highlight layer and CSS contracts were absent.
 - `python -m pytest backend\tests\test_sprint105_map_feature_extract.py backend\tests\test_sprint19_map_workbench.py backend\tests\test_sprint85_map_workspace_density.py -q` passed: 9 tests.
+- `python -m compileall backend/app` passed.
+- `cd backend && python -m pytest -q` passed: 333 tests.
 - `cd frontend && npm run typecheck` passed.
 - `cd frontend && npm run build` passed.
+- `bash scripts/run_readiness_check.sh` passed.
+- `cd backend && python -m alembic heads` passed: `202606120900 (head)`.
+- `cd backend && python -m alembic upgrade head --sql` passed.
+- `bash -n scripts/live_migration_smoke.sh` passed.
+- `powershell -NoProfile -ExecutionPolicy Bypass -File scripts\deploy_tower.ps1` passed and redeployed commit `561304c` to Tower on port 1202.
+- Deploy-time live migration smoke passed after database readiness attempt 3; PostGIS reported `3.6 USE_GEOS=1 USE_PROJ=1 USE_STATS=1`, required runtime schema objects were present and Alembic head was `202606120900`.
+- Deploy-time browser runtime verification passed for frontend, API proxy and icon.
+- Internal browser live check confirmed the Map workspace renders the `Selection & extract` panel and empty selection guidance at `http://192.168.10.150:1202`.
+- Live frontend bundle check confirmed `Selection & extract`, `selected-feature` and `Download selected GeoJSON` markers in `/assets/index-DVYT-JPu.js`.
 
 Limitations:
 - This pass extracts the single currently clicked and loaded map feature only.
 - Rectangle, lasso or polygon selection over persisted PostGIS `vector_features` still requires a backend spatial query endpoint and drawing workflow.
+- Internal browser canvas clicks did not reliably hit the small demo polygon features during validation; static regression tests, TypeScript build and live bundle markers verify the MapLibre selection wiring, and the live UI panel is present.
 - No backend API contract, migration, provider fetching, AI dependency or persistence behavior changed.
 
 Next recommended pass:
