+## Sprint 21 V1 demo workflow smoke hardening (2026-06-17)
+
+Changed:
+- Hardened `scripts/verify_demo_export_workflow.sh` so the explicit offline demo smoke validates area GeoJSON, fixture datasets, vector FeatureCollection content, vector feature summaries, persisted QA/QC metrics and export downloads through the frontend proxy.
+- Updated the frontend demo workflow action to open the candidate vector fixture dataset after seeding/loading the demo, so the Map Workbench is populated without a manual dataset click.
+- Added regression tests for the strengthened smoke script and frontend demo loading contract.
+- Updated scripts/frontend documentation, changelog and TODO status.
+
+Tested:
+- Pending validation in this pass: backend compile, backend pytest, readiness, frontend typecheck/build, Alembic checks, demo/export smoke, Tower deploy and browser audit.
+
+Known limitations:
+- The demo smoke intentionally seeds fixture demo data when run; it should be used as an explicit verification command, not as an implicit healthcheck.
+
+Next recommended pass:
+- Add a compact V1 dashboard/status strip for project, AOI, datasets, QA and exports so operators can see readiness at a glance after opening a project.
