 # Changelog
 
+## Sprint 98 demo raster workflow smoke (2026-06-23)
+
+- Added `scripts/verify_demo_raster_workflow.sh` to validate the browser-facing demo raster happy path: inspect, preview, stats and tile manifest generation.
+- Added readiness syntax coverage for the raster workflow smoke.
+- Fixed raster tiling manifest generation for Rasterio versions that return window bounds as tuples instead of bound objects.
+- Added regression coverage for tuple-based raster window bounds and the new raster smoke contract.
+- No AI inference, external provider fetching, migrations or API route changes were introduced.
+
 ## Sprint 97 demo raster fixture workflow (2026-06-23)
 
 - Added a deterministic local GeoTIFF raster fixture to the offline demo workflow so raster controls and AI Lab dataset prerequisites have usable V1 context.

+## Sprint 98 demo raster workflow smoke (2026-06-23)
+
+Changed:
+- Added `scripts/verify_demo_raster_workflow.sh`, a browser-facing runtime smoke for the seeded `demo_context_raster.tif` fixture.
+- Added the new smoke to readiness syntax checks.
+- Hardened `RasterOperationsService.tile` so tile manifest bounds accept both Rasterio tuple bounds and object bounds.
+- Updated `backend/tests/test_raster_operations_service.py` to cover tuple-based window bounds.
+- Added `backend/tests/test_sprint98_raster_workflow_smoke.py`.
+- Updated `scripts/README.md` and `CHANGELOG.md`.
+
+Validation:
+- RED: `python -m pytest backend\tests\test_sprint98_raster_workflow_smoke.py -q` failed before implementation because `scripts/verify_demo_raster_workflow.sh` did not exist.
+- `python -m pytest backend\tests\test_sprint98_raster_workflow_smoke.py backend\tests\test_readiness_gate.py -q` passed: 14 tests.
+- `bash -n scripts/verify_demo_raster_workflow.sh` passed.
+- Live diagnostic run of `bash scripts/verify_demo_raster_workflow.sh http://192.168.10.150:1202` showed inspect, preview and stats passed, then raster tile failed with HTTP 500.
+- Tower backend logs identified the root cause: `rasterio.windows.bounds(...)` returned a tuple, while tile manifest generation expected `.left/.bottom/.right/.top` attributes.
+- RED: `python -m pytest backend\tests\test_raster_operations_service.py::test_raster_tile_returns_manifest_payload -q` reproduced the live `AttributeError` after updating the fixture to tuple bounds.
+- `python -m pytest backend\tests\test_raster_operations_service.py::test_raster_tile_returns_manifest_payload backend\tests\test_sprint98_raster_workflow_smoke.py -q` passed: 2 tests.
+- `python -m compileall backend/app` passed.
+- `python -m pytest -q` from `backend/` passed: 321 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.
+
+Limitations:
+- The raster smoke creates a small tile set each run. It is appropriate for local/runtime validation, not high-volume benchmarking.
+- The smoke intentionally does not run AI inference or external imagery/provider fetching.
+
+Next recommended pass:
+- Run full readiness, redeploy, then verify the raster smoke live against `http://192.168.10.150:1202`.
