+## Sprint 80 Operation form readability polish (2026-06-20)
+
+Changed:
+- Added structured headings, helper text, field wrappers, responsive field grids and action rows to raster operation controls.
+- Added equivalent readability structure to vector clip, buffer and intersect controls.
+- Added inline dataset tool error styling for raster clip/tile validation messages.
+- Added `backend/tests/test_sprint80_operation_form_readability.py`.
+- Updated `frontend/README.md`, `docs/TODO.md` and `CHANGELOG.md`.
+
+Tested:
+- Red step: `python -m pytest backend/tests/test_sprint80_operation_form_readability.py -q` failed on missing form readability CSS and markup contracts.
+- `python -m pytest backend/tests/test_sprint80_operation_form_readability.py -q` (`3 passed`)
+- `python -m pytest backend/tests/test_sprint80_operation_form_readability.py backend/tests/test_sprint77_inspector_mobile_polish.py backend/tests/test_sprint29_dataset_components.py backend/tests/test_sprint28_dataset_workflow_hook.py backend/tests/test_vector_operations_service.py backend/tests/test_raster_operations_service.py -q` (`37 passed`)
+- `cd frontend && npm run typecheck`
+- `cd frontend && npm run build`
+- `bash scripts/run_readiness_check.sh` (`273 passed`; frontend typecheck/build passed; Alembic single head `202606120900`)
+
+Open:
+- Run full readiness, redeploy Tower and verify live runtime smoke after deployment.
+
+Limitations:
+- Frontend readability/presentation polish only; no raster/vector operation behavior, API contract, persistence, migration, provider fetching or AI/model changes.
+
+Next recommended pass:
+- Continue with compact empty/error-state polish across QA, exports and AI lab result panels.
