A user who belongs to organizations still has no organization id in the session until setActive has run for that session, and switching organizations mints a new token with new claims.

Server code that reads the organization id from the auth helper and treats undefined as no access will lock users out immediately after sign-in, before any organization has been selected. Either force a selection step in the post-sign-in flow, or persist a last-used organization per user and set it during the redirect. Keep the authorization decision on the server against the session claims: the organization switcher is a client component and the value it displays is not what protects the route.
