@@ -74,6 +74,11 @@ Therefore the palette is replaced, not extended, and the replacement is built on
 - Installs to `kf6/ktexteditor`; metadata verified valid via `KPluginMetaData`.
 - Not yet wired: frecency (the model supports a bonus, but the plugin currently
   passes 0 for every action — usage tracking is deferred).
+- Duplicate handling: actions are deduplicated by pointer identity (the same
+  action reachable through several GUI clients is listed once). Distinct actions
+  that merely share a visible label (e.g. two plugins each offering "Reload")
+  are kept but disambiguated with their component name, and every entry gets a
+  unique id so activation always triggers the right action.
