+# RetrieX SSE final think cleanup fix
+
+This patch fixes a frontend finalization issue where the SSE stream could receive
+`event: done` / `[DONE]`, but the last transient `.think` status such as
+"Denke nach..." stayed visible.
+
+The streaming renderer still keeps the latest `.think` block while the answer is
+running. On final `done`, it now removes all transient `.think` blocks and also
+removes the loader CSS class. This is a UI-only fix and does not change retrieval,
+prompting, shop search, scoring, or SSE job logic.
+
+Changed files:
+
+- public/assets/js/base.js
+
+After applying the patch, clear Symfony/browser asset cache as appropriate.
