Replaces 4 separate frustration API calls with single useBehavior hook.
Removes manual fetchData, loading/error state, and refresh interval—SWR
handles caching, revalidation, and error state automatically.
Replace useDashboardOverview, useDashboardPages, useDashboardLocations,
useDashboardDevices, useDashboardReferrers, useDashboardPerformance, and
useDashboardGoals with a single useDashboard hook that calls the existing
/dashboard batch endpoint. This endpoint runs all queries in parallel on
the backend and caches the result in Redis (30s TTL).
Reduces dashboard requests from 12 to 6 per refresh cycle (50% reduction).
At 1,000 concurrent users: ~6,000 req/min instead of 12,000.
Dashboard filtering: FilterBar pills, AddFilterDropdown with dimension/
operator/value steps, URL-serialized filters, all SWR hooks filter-aware.
Custom event properties: pulse.track() accepts props object, EventProperties
panel with auto-discovered key tabs and value bar charts, clickable goal rows.
Updated changelog with both features under v0.13.0-alpha.
Replace 22 manual useState + useEffect + setInterval polling with 11
focused SWR hooks. Removes ~85 lines of polling/visibility logic that
SWR handles natively. All any[] types replaced with proper interfaces
(TopPage, CountryStat, BrowserStat, etc.). Organization state in layout
typed as OrganizationMember[].
Resolves F-7, F-8, F-15 from audit report.
