Blocked: Auth.js compatibility

The SvelteKit 3 migration is blocked on a supported @auth/sveltekit integration.

The assessed latest release, @auth/sveltekit@1.11.3, declares only SvelteKit 1/2 support and imports $app/paths.base, which SvelteKit 3 removed. This is a build incompatibility, not just a peer-range warning. Upstream also reports external-redirect compatibility work: https://github.com/nextauthjs/next-auth/issues/13502 (bot-closed for reproduction requirements, not fixed).

Do not force peer resolution, silently patch authentication, or replace the auth system as part of this upgrade. Unblock when a supported adapter is available and credentials/OIDC/session/redirect behavior can be verified, or after a separately approved auth-compatibility decision.

Migration scope when unblocked

  • Coordinate Kit 3, adapter-node, Vite/plugin, TypeScript 6 and exact Svelte versions across web/worker/templates.
  • Migrate configuration, package imports and native test fixtures; preserve runtime configuration and request-origin behavior.
  • Use Kit 3's unified handleError for error-page customization rather than replacing error calls throughout application routes.

The unpublished Kit 2 custom-error draft has been reverted. Existing built-in error views remain the temporary behavior; landed home/feed Markdown support is retained.

Blocked follow-up

Custom Markdown error pages: #153. This feature remains deferred until this migration is unblocked.
