 ## [Unreleased]
 
+### Changed
+
+- **Live Compact Worklog summaries can now be expanded or collapsed while a response is still streaming.** The `Processed …` row keeps its timer and now behaves like the settled Worklog disclosure, so users can hide noisy live work details without waiting for the final answer.
+
 ## [v0.51.603] — 2026-06-23 — Release VJ (cache the app-shell template)
