A server module in a client graph aborts hydration in the browser. New leaks fail CI; known leaks are tracked in |
📝 WalkthroughWalkthroughThe PR adds configurable redirect destination validation. It supports canonical HTTP(S) origin allowlists, trusted browser-visible request origins, proxy authority preservation, SSR and page-data enforcement, and a dedicated runtime error with documentation. ChangesRedirect destination security
