Every edbn/ui component ships against these 20 checks. Server rendering, hydration, concurrency, portals — if it can break, we test for it.

Built for tomorrow's React, not yesterday's.

#	Pattern	Check
01	Server-Proof	No window/document/localStorage outside useEffect
02	Hydration-Proof	SSR output matches client's first render
03	Instance-Proof	useId() or useStableId() for all generated IDs
04	Concurrent-Proof	No side effects in render body
05	Composition-Proof	No cloneElement or Children.map
06	Portal-Proof	ownerDocument.defaultView for global listeners
07	Transition-Proof	Interactive state updates in startTransition
08	Activity-Proof	DOM side effects cleaned up via media or useLayoutEffect
09	Leak-Proof	Every effect has cleanup
10	Future-Proof	useMemo for perf only, useState for correctness
11	Race-Proof	Fetch effects use ignore flags or AbortController
12	Derived-State	No effect chains; derive during render
13	Type-Safe Context	Custom hooks throw if used outside provider
14	External-Store	useSyncExternalStore for browser/third-party data
15	StrictMode	Component survives double-mount without bugs
16	Key Reset	State resets use key, not effects
17	Accessible	Keyboard nav, ARIA attributes, focus management
18	Barrel-Safe	No naming conflicts in re-exports
19	Theme-Isolated	CSS vars scoped per instance
20	Handler vs Effect	Side effects in correct location
