+### ADP-014 - Extract Cloud Browser Loading Placeholder Helper
+
+Status: Done
+Score: no score movement
+Debt: `DEBT-0038`
+Scope: `src/node_dialog_cloud.*` only
+
+Goal:
+
+Reduce the inline retained cloud-browser loader surface in
+`NodeDialogCloud::load_thumbs_thread()` by extracting the initial loading
+placeholder setup into a focused helper while preserving current behavior.
+
+Done Checks:
+
+- The initial loading placeholder setup no longer lives inline in
+  `NodeDialogCloud::load_thumbs_thread()`.
+- The retained cloud-browser loading placeholder now routes through a focused
+  helper in `src/node_dialog_cloud.*`.
+- `DEBT-0038` and the roadmap note the reduced remaining `NodeDialogCloud`
+  surface.
