…tility-Protocol#63) Coordinates the four data domains (blockchain, telemetry, metadata, spatial) behind named Suspense boundaries with stale-while-revalidate caching and a fallback cascade. - types/suspense.ts: DomainKey, per-domain Suspense timeouts (10/3/5/8s) and cache TTLs (30/5/120/300s), CacheEntry, SuspenseResource, cache-group helpers - store/slices/cacheSlice.ts: per-key entries with fetched-at/TTL, isFresh/ isStale, CACHE_UPDATED/PENDING/REJECTED, and group + single-key invalidation - utils/suspenseResource.ts: createResource(read/prefetch/invalidate/peek) — throw-promise pattern with SWR (fresh→data, stale→data+background revalidate, missing→suspend, rejected→throw), de-duplicated in-flight fetches - hooks/useSuspenseResource.ts: reads a resource and re-renders on cache updates - components/boundaries: ErrorBoundary, domain skeletons, ErrorPanel, the generic DomainBoundary (Retry → invalidate groups + remount), the four primary boundaries, the dashboard/map composites, and a CascadeProvider/CascadeGate for the fallback cascade - components/dashboard/DashboardPage.tsx: composes the boundaries (component, not src/pages, since this is an App Router project) - services/soroban.ts: adds promise-based readContractState for Suspense wrapping - tests for the cache store, the resource factory (suspend/SWR/reject/invalidate/ dedup), and RTL boundary behaviour (fallback->content, error+retry, cascade)
