+# Handoff — Tourism Vertical Slice
+
+## Project
+
+- Path: `/Users/kunthawat/Gitea/set50-alternative-data-platform`
+- Mode: research + paper only
+- Frontend: Vue 3 + Vite
+- Backend: Flask
+- Current data: deterministic fixture with lineage metadata
+
+## Completed
+
+- Tourism snapshot schema with source, publication, retrieval and vintage fields.
+- Deterministic Tourism Pulse score: standardized surprise × exposure × confidence.
+- Ranked target weights and LONG/SHORT/NEUTRAL classification.
+- Flask endpoints for health, summary, observations, signals and paper ledger.
+- English dashboard with live API data, lineage panel, signal table and paper-entry form.
+- No external webhook or MT5 integration.
+
+## Verified commands

+```text
+PYTHONPATH=backend .venv/bin/python -m unittest discover -s backend/tests -v
+Ran 10 tests ... OK
+
+Paper writes use a server-side token exchange and HttpOnly `paper_session` cookie; the token is not embedded in the frontend bundle.

+
+## Known limitation
+
+The data adapter is a fixture. It demonstrates the contract and calculation, not live tourism data quality. Browser visual screenshot verification was blocked by a Chrome remote-debugging permission prompt; served HTML, API response and frontend build were verified instead.
+
+## Next action
+
+Implement one replayable Tourism source adapter without changing the snapshot contract. Add parser fixture tests, publication timestamp handling, raw snapshot hash, and a data-health failure state before adding LLM analysis.
