X_REALTIME_UNINSTALLED

a realtime hook ran in an island bundle that never installed realtime

useQuery, useRecord, useMutation or useConnection in a browser island whose bundle never called installRealtime(), or on a page where the page runtime (@ultimat3/realtime/boot: the store, the socket, the transport) never loaded. A server render is not this: with no DOM the hooks answer their server-render state

x build. It builds an island whose own import graph reaches @ultimat3/realtime from an entry that awaits the page runtime — the page boot, or the /islands/page-runtime.<id>.js chunk where no boot is rendered — and calls installRealtime({ signal: createSignal }) first (packages/cli/src/island-realtime.ts). The one case it misses is a package that imports realtime on the island's behalf, or an island built by hand. That island's page loads import '@ultimat3/realtime/boot' before the island, and the island calls installRealtime({ signal: createSignal }) in its mount, before its first render
