 ### Fixed
 
+- **A busy Kanban board no longer pushes your regular conversations out of the sidebar.** The sidebar builds its session list from a bounded 20-row candidate window, and Kanban runs were competing in that window — so on a profile with 20+ recent Kanban runs, those rows could fill the window and evict your CLI / TUI / ACP / messaging conversations from the list. Kanban now gets its own dedicated, bounded recovery pass (the same pattern cron and webhook sessions already use), so a high-volume Kanban worker can't crowd out interactive conversations. Explicitly filtering the sidebar to Kanban still shows them normally. Thanks @zicochaos. (#6998)
+
 - **The workspace file-sort menu is now fully translated in all 14 non-English languages.** The six sort options (Sort by, Name A→Z / Z→A, Date created / modified, and the "creation time unavailable" note) were still showing English placeholder text in the non-English locales after they were added in #6091; they're now translated into German, Spanish, French, Italian, Portuguese, Czech, Turkish, Polish, Russian, Japanese, Korean, Chinese (Simplified and Traditional), and Vietnamese. Thanks @webtecnica. (#6910)
 
 - **Streaming text can no longer render into the wrong conversation when you switch sessions mid-response.** If one session was still streaming and you switched to another, a render that had already been scheduled could fire after the switch and briefly write the first session's tokens into the second session's pane. The live-stream render path now re-checks that its session is still the active one right before it writes to the DOM (including inside the deferred animation-frame/timeout window), so a scheduled render is dropped instead of leaking into the wrong pane; the streamed text is preserved and re-renders correctly when you switch back. Thanks @webtecnica. (#6502)
