* fix(beszel): harden cache layer and prevent blank widgets
- Add debug logging across Beszel integration, request handler, and tRPC
router (auth, fetch, SSE, per-procedure entry/exit) gated behind
LOG_LEVEL=debug
- cached-request-handler: retry with backoff, isValid predicate to skip
caching invalid data, in-flight dedup (single-flight per channel) to
avoid thundering herd after cache invalidation
- redis channel: set-then-publish so storage is always consistent even
when pubsub publish fails
- Beszel handlers: opt into fallbackToStaleOnError and retry so brief
upstream hiccups don't throw away good cached data
- beszel-system-stats: add refetchInterval matching each time period's
cache TTL so historical charts refresh in the background
- tRPC router: switch Promise.all -> Promise.allSettled for getSystems
and getAlerts; getSystemStats returns an error object instead of
throwing. Each result carries an optional error field so one failed
integration no longer nukes the whole widget
- Widgets: add explicit isPending loader, empty state for grid and
stats, and a shared per-integration error indicator (tooltip with
failed integration names). Alerts and table now only show their
empty state after loading completes
- Translation: add empty.noSystems key to beszelSystemGrid and
beszelSystemStats

- Remove ternary operators from new code (widget-integration-select,
TabsContainer, mock data, members page)
- Remove stale /docs/management/tools/backup from sitemap type
- Add value prop to error-state Select in beszel-system-stats
Consolidate 5 stat mapper useCallbacks and 6 series useMemos into
single mappers/series objects. Extract statsWhenShown helper for
repeated visibility guard pattern. Deduplicate SSE record envelope
construction. Simplify prepareRecords with if/else. Remove unused
gridColumns ternary with Number() indexing.
Replace all ternary operators with if/else, &&/||, or early returns.
Remove unused noAnimation constant that caused lint error.
Fix variable shadowing in tooltip deduplication loop.
- Decouple 1Hz SSE ingestion from render rate: accumulate data in a
ref and flush to React state every 3s instead of every tick
- First data point flushes immediately to avoid blank screen
- Reduce MAX_BUFFER from 60 to 30 (halves SVG reconciliation work)
- Gate chart data hooks behind visibility flags so disabled charts
skip all array processing
- Set withDots={false} to eliminate thousands of hidden SVG Dot nodes
- Disable Recharts animation (isAnimationActive: false) during data updates
- Merge ChartPanel + BeszelAreaChart into BeszelChartPanel to fix
React.memo being defeated by children prop creating new refs
- Memoize yAxisProps inside BeszelAreaChart instead of rebuilding inline
- Hoist chartStyle, panelStyle, CPU_Y_AXIS_DOMAIN to module constants
- Memoize subscription input/enabled in useLiveStats
- Replace O(n) find() with Map lookup in useDockerChartData hot path
- Stabilize useContainerNames with ref comparison so it returns the
same array reference when container names haven't changed
- Memoize containerSeries (was computed inline every render)
- Hoist all system chart series arrays into useMemo
- Hoist activeDotProps/dotProps to module-level constants
- Wrap BeszelAreaChart and ChartPanel in React.memo
When SSE connection fails, the error UI now shows a specific message
and a button to switch back to historical view, so users don't need
to reload the page to recover.
- Restore timePeriod union cast to fix typecheck (TS2769)
- Clear live data on subscription error so error UI always shows
- Emit error when no integration is configured for live subscription
- Add error state to system select input when query fails
- Surface subscription errors in useLiveStats via onError + error state
- Show error UI in live mode when SSE connection fails
- Abort SSE reader on subscribeTopic failure instead of silent log
- Guard mock realtime against pre-aborted signal to prevent interval leak
- Remove dead includeDocker from subscription input schema
- Gate stats/live queries on systems loading state to prevent stale ID
requests during initial load
- Simplify useLiveStats: functional setState, stable integrationKey dep,
remove unused includeDocker param
- Extract prepareRecords helper to deduplicate chart ordering logic
- Remove stale timePeriod type cast
Add "Live" option to time period selector that uses the existing
subscribeSystemStats tRPC subscription (PocketBase SSE) instead of
REST polling. A useLiveStats hook accumulates incoming data points
in a 60-entry rolling buffer. Charts use HH:mm:ss timestamps in
live mode.
BeszelAreaChart hardcoded type="stacked" for all charts, causing Docker
Network I/O to render blended colors that didn't match the tooltip.
- Make `type` prop configurable (default "default")
- Only stack Memory, Docker CPU, and Docker Memory charts
- Add systemId as a persisted widget option with Menu-based selector
- Replace Popover with Menu trigger="click-hover" for proper hover UX
- Show error state with Select when selected system is not found
- Remove 1-minute time period (live SSE not wired yet)
