Integration review (#168): the content pane opened a pane for whatever the sidebar highlighted with no status check. After a host reboot every session is dormant, so arrowing down the sidebar opened a pane per session that immediately died with WS 1006 (the daemon answers a bridgeless attach with 404/409, never a completed handshake). Gate every path that fills a pane (preview, open, mobile's single pane) on the session's own status: a session that isn't Running gets the same metadata-and-resume view its sidebar card shows (docs/SIDEBAR.md, docs/PREVIEW.md) instead of an attach attempt. The shell also reacts to onNeverAttached (previous commit) by dropping the dead connection and re-rendering, and to an open session's Running-ness flipping — most commonly a resume completing — so a placeholder and a live pane swap in step with the catalog.
