Shell:
- One shared NexusLayout for ALL routes (dashboard + pages): compact 68px
icon rail with hover-expand overlay, replaces both old sidebars + topbars
- Single flat nav source (railNav) — same menu everywhere incl. Settings
- Removed dead shell components (AppSidebar, AppHeader, Topbar, NavGroup,
NavItem, ModuleView) and dead nav routes; App.vue is now just RouterView
Live updates:
- Fix SSE loop in DashboardController: PeriodicTimer.WaitForNextTickAsync and
ChannelReader.ReadAsync were re-invoked while pending — every published
update threw InvalidOperationException and killed ALL live streams
- liveSync store: treat graceful stream close as disconnect (was stuck
connected=true with polling stopped -> page frozen until manual reload),
fast first retry, heartbeat watchdog (65s), reconnect on online/visibility
- One app-wide SSE connection owned by the layout instead of per-view
connect/disconnect churn; removed duplicate live-sync.ts store
Performance:
- Board endpoint: drop nested childTasks duplication (counts stay) — payload
104KB -> 65KB; SSE snapshots shrink equally
- nginx: gzip for JSON/JS/CSS (board 18KB, bundle 95KB over the wire);
text/event-stream excluded to keep SSE unbuffered
