Since Wrangler v3 the development server runs the Worker in a local workerd with local storage for KV, D1, R2, Durable Objects and Queues, persisted under .wrangler/state. Nothing touches the account unless --remote is passed. That is why a local session can pass while production fails on a missing namespace or an unapplied migration.
Some bindings have no local implementation and always go remote, notably Workers AI, Vectorize and Browser Rendering, so those need credentials even in local mode. Selected bindings can be made remote individually while the rest stay local. Deleting .wrangler/state resets every local store at once, and the persist-to flag points state at a different directory, which is useful for keeping a throwaway fixture set apart from a working one.
