+### ADP-038 - Extract Document-Session Overwrite Prompt Helper
+
+Status: Done
+Score: no score movement
+Debt: `DEBT-0040`, `DEBT-0041`, `DEBT-0042`
+Scope: `src/legacy_document_session_services.cpp` only
+
+Goal:
+
+Reduce the inline retained document-session overwrite-prompt surface by
+extracting the shared OK wiring from the new-document and save-file overwrite
+prompts into a focused helper while preserving current behavior.
+
+Done Checks:
+
+- The retained document-session overwrite-prompt OK wiring no longer lives
+  inline in the new-document and save-file prompt methods.
+- The retained document-session overwrite-prompt path now routes through a
+  focused helper in `src/legacy_document_session_services.cpp`.
+- `DEBT-0040`, `DEBT-0041`, `DEBT-0042`, and the roadmap note the reduced
+  remaining document-session bridge surface.
