+
+Status: Done
+Score: no score movement
+Debt: `DEBT-0039`
+Scope: `src/legacy_document_open_services.cpp` only
+
+Closeout: `39728e46`

+- The retained unsaved-project discard prompt path now routes through a focused
+  helper in `src/legacy_document_open_services.cpp`.
+- `DEBT-0039` and the roadmap note the reduced remaining document-open bridge
