fix: send signed-out visitors to login instead of a blank page (EN-157) - #1289
After signing in, you can return to the page you were trying to access, when available.
Bug Fixes
Sign-in and sign-out handle expired or unavailable sessions more clearly and direct you to the appropriate sign-in page.
Restricted pages show an access-denied message and redirect without adding an extra browser-history entry.
Sign-out clears session-related state.
When a session has expired while loading a page, signing in again can return you to that page.
Authentication now distinguishes session outcomes, saves and restores return paths, and handles logout through Kratos browser logout. Route loaders handle signed-out sessions, and the route guard checks access, displays an access-denied toast, and replaces history when redirecting denied users.
Changes: Authentication and Route Access
Layer / File(s)
Summary
Session status and return paths frontend/src/auth/useAuth.ts, frontend/src/auth/AuthProvider.tsx
checkSession distinguishes authenticated, signed-out, and unavailable responses. The provider handles each outcome and sets digital-transcript storage ownership for a valid session. Return paths are saved except on /authcallback, validated, and consumed after successful authentication.
Loaders pass the request to redirectOnError. For signed-out 401 responses, it calls signInAgain with the request URL. Other failures retain the status-based redirects.
handleLogout clears analytics and tab-session state, dispatches the logout event, and requests Kratos browser logout. It navigates to the returned logout_url or falls back to the initial Kratos login flow.
The guard checks roles and required features for a present user. It displays an access-denied toast and redirects denied users with history replacement. AuthenticatedShell renders the Toaster outside AuthProvider.
Merge Risk: Low · up to cb9e7
Signed-out visitors are now redirected to login instead of seeing a blank page. Edge cases remain: a stalled or failed logout request can leave a blank page or cause a redirect loop, and a session-check outage after a 401 is reported as an authorization error. These are low-impact and worth fixing before or soon after merge.

- Around line 30-35: Mount the Toaster before the guarded outlet in the
application layout so it is subscribed before RouteGuard emits the access-denied
toast on direct navigation. Keep the existing toast behavior and configuration
unchanged.
Review comments at @frontend/src/auth/useAuth.ts:
- Around line 84-87: Update checkRole to distinguish the 'unavailable' result
from a signed-out session: propagate an error for unavailable, while preserving
the existing redirect behavior for signed-out users. Avoid routing an
unavailable session through fetchUser’s undefined result.
- Around line 285-287: Update the fallback redirect to INIT_KRATOS_LOGIN_FLOW in
the logout failure path to start the Kratos login flow with the refresh=true
flag, while preserving the existing redirect behavior otherwise.

@carddev81 I ran this locally. The ticket repro is fixed: signed out, /ai-tutor and /faqs go to login, and after sign-in you land back where you started, through the password reset too.
The saved return link carries over to the next user. (Low) If someone is sent to login and walks away, the next person to sign in on that tab lands on their URL (useAuth.ts:93-111). Add an expiry, or clear it on /login.
Program and class deep links still go to the 403 page, not login. (Medium)redirectOnError sends a 401 to /unauthorized (routeLoaders.ts:321). main does the same, but the ticket says "any route".
A session that expires while the app is open isn't caught. (Medium) The check only runs on load (AuthProvider.tsx:22-57). Fix it here or point to EN-227.
No-access shows a toast, not an error page, and on a direct load the toast doesn't show at all. (Low)
Will approve once finding 1 is fixed, with 2 and 3 fixed here or split into tickets.

Thanks, all four checked.
Fixed: the saved page now expires after 10 minutes, Kratos's login flow lifespan. Clearing it on /login wouldn't work, because /login is on the way back to the page.
Fixed:redirectOnError now checks the session on a 401. Signed out goes to login and back. A signed-in user without access still gets /unauthorized, since core answers 401 for "not an admin" too.
Out of scope: that's EN-227, the stale-tab ticket. Catching every API 401 mid-session is a separate change in api.ts. Expiry is caught on page load, and now on program and class navigation too.
Fixed: the toast fix wasn't in my first push. It's in now, so it shows on a direct load. I'm keeping the toast plus the redirect home: it says what happened and lands you on your home page, as the ticket asks. /unauthorized only has a Back button, which leaves the app on a direct load.

Bound the logout request used by signed-out redirects.
If the logout request stalls, AuthProvider can show a blank page while it waits for handleLogout. Bound the request and response-body wait, and handle a timeout without leaving a blank page. Preserve successful Kratos logout and avoid redirect loops when a session remains active.

@carddev81 Re-reviewed at cb9e788 on a local stack. Fixes 1, 2 and 4 work: a saved page older than 10 minutes is ignored, signed-out program and class deep links go to login and back, and the no-access toast now shows on a direct load. A signed-in resident on a program page still goes home, not to login, and CI is green. Agreed that 3 belongs in EN-227.
