The desktop shadow of useEndpointConfig hand-rolled dedupe, a 2.5s backend-starting retry loop, and health-monitor-driven refetches across two subscriptions. It now runs on the same TanStack Query foundation as the web version (#7285), keeping every behaviour the characterisation tests pin down. The domain logic that is not caching moves into desktop/api/endpointAvailability as plain resolve functions: the self-hosted-offline per-endpoint local check, the legacy 400 query-param fallback, SaaS-mode optimism, and the fail-closed map. The dependency-ready gate becomes a retryable BACKEND_NOT_READY error, so Query's retry replaces the manual setTimeout loop. Backend readiness is tracked with useSyncExternalStore (the pattern desktop useGroupEnabled established), so the query wakes when the backend comes up; a readiness change invalidates the cache, which is how a reconnect swaps the offline answer for the live one. The hook shrinks from 485 lines to ~180, and the two return shapes are unchanged, so no consumer is touched.
