+### ADP-047 - Extract Document-Open Project Result Branch Helpers
+
+Status: Done
+Score: no score movement
+Debt: `DEBT-0039`
+Scope: `src/legacy_document_open_services.cpp` only
+
+Closeout: `2f2b9621`
+
+Goal:
+
+Reduce the inline retained project-open result branch surface by extracting the
+success-path layer refresh and failure-path error dialog from
+`handle_open_legacy_project_result()` into focused helpers while preserving
+current behavior.
+
+Done Checks:
+
+- The retained project-open success-path layer/title work no longer lives
+  inline in `handle_open_legacy_project_result()`.
+- The retained project-open failure-path error dialog no longer lives inline in
+  `handle_open_legacy_project_result()`.
+- The retained project-open result path now routes through focused helpers in
+  `src/legacy_document_open_services.cpp`.
+- `DEBT-0039` and the roadmap note the reduced remaining document-open bridge
+  surface.
