+
+## Out of Scope
+
+| Feature | Reason |
+|---------|--------|
+| PostgreSQL migration | SQLite sufficient for single-user app |
+| Authentication / multi-user | Single user, no login needed |
+| Custom comparison parameters | Complexity trap, weight/price covers 80% |
+| Mobile native app | Web-first, responsive design sufficient |
+| Social/sharing features | Different product |
+| Price tracking / deal alerts | Requires scraping, fragile |
+
+## Traceability
+
+Which phases cover which requirements. Updated during roadmap creation.
+
+| Requirement | Phase | Status |
+|-------------|-------|--------|
+| DB-01 | — | Pending |
+| IMG-01 | — | Pending |
+| IMG-02 | — | Pending |
+| IMG-03 | — | Pending |
+| IMG-04 | — | Pending |
+| PLAN-01 | — | Pending |
