+### ADP-036 - Extract Downloaded Project Open Prep Helper
+
+Status: Done
+Score: no score movement
+Debt: `DEBT-0038`
+Scope: `src/legacy_document_open_services.*` only
+
+Closeout: `69603ed6`
+
+Goal:
+
+Reduce the inline retained downloaded-project open setup surface by
+extracting the camera reset and layer-clear path from
+`execute_legacy_downloaded_project_open()` into a focused helper while
+preserving current behavior.
+
+Done Checks:
+
+- The retained downloaded-project camera reset and layer-clear setup no
+  longer lives inline in `execute_legacy_downloaded_project_open()`.
+- The retained downloaded-project open setup now routes through a focused
+  helper in `src/legacy_document_open_services.cpp`.
+- `DEBT-0038` and the roadmap note the reduced remaining cloud bridge
+  surface.
