App.tsx's prepare() useEffect ran four .init() calls
(SessionDataManager, RoomSessionManager, RoomEngine, Communication)
without any guard, plus an immediate heartbeat ping and a legacy
authentication track. Under StrictMode dev double-invoke, those
fire twice — risking duplicate session/communication state.
- Gate the four .init() chain behind gameInitPromiseRef: both the
first and the simulated second invocation await the same promise.
- Gate the legacy track + immediate heartbeat behind bootstrapDoneRef.
- Heartbeat and remember-rotate intervals were already idempotent
(clearInterval before setInterval); ticker registration was already
guarded by tickersStartedRef; renderer/warmup were already gated by
rendererPromiseRef/warmupPromiseRef. No change needed there.
Wrap <App /> in <StrictMode> in src/index.tsx now that the renderer
init path is double-invoke safe.

Adopt React 19 idioms across the codebase. The runtime was already on
react@19.2.5 but no React 19 APIs were in use.
- forwardRef -> ref-as-prop in 7 layout/component files
(NitroInput/Button/ItemCountBadge/Card×5/InfiniteGridItem,
ToolbarItemView, AvatarEditorIcon)
- <Ctx.Provider> -> <Ctx> in 6 contexts (CatalogAdmin, FloorplanEditor,
UiSettings, GridContext, NitroCardContext, NitroCardAccordionContext)
- Native <script> hoisting for Turnstile, ExternalPluginLoader, GoogleAdsView
(React 19 dedupes by src; removes manual document.head.appendChild +
module-level promise caches)
- React Compiler enabled at build time via babel-plugin-react-compiler
in vite.config.mjs (target: '19'), plus eslint-plugin-react-compiler
in lint mode
- Global <ErrorBoundary> + <Suspense> in src/index.tsx using
react-error-boundary, with LoadingView as fallback
- BackgroundsView migrated to use(promise) as a demonstrator pattern
for Suspense-driven config loading
- ESLint react setting bumped 18.3.1 -> 19.2; legacy
@typescript-eslint/ban-types replaced with no-restricted-types
(the old rule was removed in @typescript-eslint v8)
- Refresh public/configuration/{asset-loader,bootstrap}.js to match
current write-asset-loader.mjs output
Phase 3 (login forms -> useActionState/useFormStatus) deferred:
LoginView is 1623 lines with lockout + Turnstile + heartbeat
interleaving; safer as its own PR.
