+### ADP-020 - Extract Cloud Publish Prompt Wiring Helper
+
+Status: Done
+Score: no score movement
+Debt: `DEBT-0038`
+Scope: `src/legacy_cloud_services.cpp` only
+
+Goal:
+
+Reduce the inline retained cloud-publish prompt surface by extracting the
+OK/cancel button wiring built inside `LegacyCloudServices::prompt_publish()`
+into a focused helper while preserving current behavior.
+
+Done Checks:
+
+- The retained cloud-publish prompt button wiring no longer lives inline in
+  `LegacyCloudServices::prompt_publish()`.
+- The retained publish prompt lifetime 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.
