Clicking logout previously only called supabase.auth.signOut(): Keycloak's
SSO cookie was untouched, so the (app) layout's $effect immediately
re-fired login() and Keycloak silently re-authenticated — logout looked
broken. That same chain also surfaced "PKCE code verifier not found in
storage" on prod, since signOut()'s async storage clear could race
signInWithOAuth()'s verifier write, or the $effect could double-fire and
overwrite verifiers mid-flight.
- logout(): signOut() then redirect to Keycloak's end_session endpoint
(client_id + post_logout_redirect_uri=/logged-out). Keycloak shows a
one-click "Do you want to log out?" confirmation because GoTrue's proxy
flow does not expose the id_token, so we can't pass id_token_hint.
- isLoggingOut flag + guard in (app) layout $effect: prevents auto-relogin
during the logout navigation.
- New public /logged-out route, outside the (app) group.
- A-05 rewritten, new A-07 (fresh login must prompt for credentials after
RP-initiated logout).
- pgTAP 008 extended with 4 assertions for migration 014's UPDATE trigger.
