+### ADP-045 - Extract Document-Open Unsaved Prompt Helper
+
+Status: Done
+Score: no score movement
+Debt: `DEBT-0039`
+Scope: `src/legacy_document_open_services.cpp` only
+
+Closeout: `39728e46`
+
+Goal:
+
+Reduce the inline retained unsaved-project discard prompt surface by
+extracting the button wiring from `LegacyDocumentOpenServices::prompt_discard_unsaved_project()`
+into a focused helper while preserving current behavior.
+
+Done Checks:
+
+- The retained unsaved-project discard prompt wiring no longer lives inline in
+  `LegacyDocumentOpenServices::prompt_discard_unsaved_project()`.
+- 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
+  surface.
