+## Sprint 85 Map workspace density polish (2026-06-20)
+
+Changed:
+- Added a compact Map workspace context summary for selected AOI, active layer and rendered feature state.
+- Wrapped existing layer controls and provenance in a dedicated `map-control-surface`.
+- Wrapped the existing MapLibre component in a `map-frame-surface` and the selected-feature inspector in a `map-inspection-surface`.
+- Added `backend/tests/test_sprint85_map_workspace_density.py`.
+- Updated `frontend/README.md`, `docs/TODO.md` and `CHANGELOG.md`.
+
+Tested:
+- Live browser pre-check against `http://192.168.10.150:1202` showed Map workspace had no console errors or horizontal overflow, but controls, provenance, map frame and inspector still read as a loose vertical stack.
+- Red step: `python -m pytest backend/tests/test_sprint85_map_workspace_density.py -q` failed on missing Map workspace surface and context-summary contracts.
+- `python -m pytest backend/tests/test_sprint85_map_workspace_density.py -q` (`3 passed`)
+- `python -m pytest backend/tests/test_sprint85_map_workspace_density.py backend/tests/test_sprint63_map_overlay_ergonomics.py backend/tests/test_sprint67_map_empty_state_quick_actions.py backend/tests/test_sprint74_data_map_mobile_polish.py backend/tests/test_sprint47_workbench_interaction_smoke.py -q` (`13 passed`)
+- `cd frontend && npm run typecheck`
+- `cd frontend && npm run build`
+- Live browser post-deploy check showed desktop Map workspace was structured and overflow-free, but the mobile breakpoint still stacked controls too tall above the map.
+- Red step: `python -m pytest backend/tests/test_sprint85_map_workspace_density.py -q` then failed on missing compact mobile Map workspace breakpoint contracts.
+- `python -m pytest backend/tests/test_sprint85_map_workspace_density.py -q` (`4 passed`)
+- `cd frontend && npm run typecheck`
+- `cd frontend && npm run build`
+- `bash scripts/run_readiness_check.sh` (`289 passed`; frontend typecheck/build passed; Alembic single head `202606120900`)
+- `powershell -NoProfile -ExecutionPolicy Bypass -File scripts/deploy_tower.ps1` rebuilt and redeployed the Tower all-in-one container on port 1202, then passed live migration smoke and browser runtime verification.
+- Final live browser check against `http://192.168.10.150:1202` passed on desktop and mobile viewports: no console warnings/errors, no horizontal document overflow, three Map context summary cards, two layer control cards, separated control/map/inspector surfaces and mobile control preamble reduced after the compact breakpoint correction.
+
+Open:
+- None for this pass.
+
+Limitations:
+- Frontend Map workspace presentation hierarchy only; no overlay behavior, API contract, persistence, migration, provider fetching or AI/model changes.
+
+Next recommended pass:
+- Continue with QA/QC workspace result hierarchy and filter density after this pass is deployed and visually checked.
