React Strict Mode

useFatigueState only calls peek while rendering. It never consumes on render or mount, so Strict Mode’s development re-renders do not spend a budget.

const state = useFatigueState('coupon', rules)
return <button disabled={!state.result.allowed} onClick={state.tryConsume}>Show</button>

Consume in an explicit user/event action. Avoid tryConsume in render, state initializers, or mount effects that may be replayed. Keep the provider’s value stable; changing the engine creates a new subscription store.
