+### ADP-030 - Extract Cloud Download Post-Transfer Helper
+
+Status: Done
+Score: no score movement
+Debt: `DEBT-0038`
+Scope: `src/legacy_cloud_services.cpp` only
+
+Goal:
+
+Reduce the inline retained cloud download post-transfer open/close surface by
+extracting the final worker-step path from `execute_cloud_download_thread()`
+into a focused helper while preserving current behavior.
+
+Done Checks:
+
+- The retained cloud download post-transfer open/close path no longer lives
+  inline in `execute_cloud_download_thread()`.
+- The retained cloud download post-transfer open/close path now routes through
+  a focused helper in `src/legacy_cloud_services.cpp`.
+- `DEBT-0038` and the roadmap note the reduced remaining cloud bridge
+  surface.
