In `@application/web/web_main.py`:
- Around line 886-893: The auth_callback flow must not redirect as a completed
login when upsert_user persistence fails: either return an explicit retryable
login failure, or preserve the verified OIDC session and ensure it remains
usable until persistence succeeds. Update auth_callback and the _is_logged_in
session contract so failed persistence cannot lead to a redirect followed by a
401 from /rest/v1/auth/user.
- Around line 914-916: Update the OAuth redirect flow around _safe_next,
auth_login, and auth_callback to store the validated next target in the session
before authentication begins, then redirect to that session value after a
successful callback and clear it immediately after consumption; preserve
/chatbot as the fallback when no target is stored.
- Around line 1314-1315: Update CREFlow.instance OAuth redirect URI construction
to use url_for("web.auth_callback"), matching the canonical
/rest/v1/auth/callback route, and ensure that canonical URI is registered with
the OAuth provider before removing the deprecated alias.

…lure, drop dead next
- Point the OAuth redirect_uri at the canonical url_for("web.auth_callback")
instead of the deprecated web.callback alias (CodeRabbit).
- On the OIDC callback, fail explicitly instead of leaving a broken session:
abort 503 when user persistence raises SQLAlchemyError, abort 401 when the
provider returns no 'sub'. Previously these logged and redirected to /chatbot
without session['user_id'], bouncing the user into an endless login loop.
- Drop the dead '?next=' from the browser auth challenge (auth_login never
consumed it and the callback always lands on /chatbot); redirect to the
constant /rest/v1/auth/login. Removes the CodeQL "URL redirection from remote
source" finding and the now-unused _safe_next helper.
- Tests: assert the no-next redirect; add callback persistence-failure (503)
and missing-sub (401) cases.

…drail (OWASP#963) The four canonical auth routes (/rest/v1/auth/{login,callback,logout,user}) are OAuth/redirect endpoints, not part of the documented read-only public API. Add them to OPENAPI_GUARDRAIL_EXEMPT_RULES alongside their deprecated pre-OWASP#963 aliases, matching how the old paths were already treated. No PathSpecs and no openapi.yaml regeneration -- the guardrail's route-coverage check passes because these rules are exempt, not documented.
The canonical /rest/v1/auth/callback path called redirect() without return, so token verification and session writes continued after a state mismatch. Add a regression test.

Maintainer pass on the /rest/v1/auth/* migration.
Persistence-failure → 503 (no broken session) was already correct on this branch.
?next return-to-page is explicitly deferred — fine for this PR.
Pushed 13ff289: return on OAuth state-mismatch redirect (same bug as #1021) + regression test. Auth route tests pass locally.
LGTM once CI is green. Closes #1021 when merged.

Summary
Migrates the OAuth/login endpoints to a canonical
/rest/v1/auth/*namespace(RFC #876, TODO 1 / issue #963), keeps the old paths working as
deprecation-flagged aliases, and consolidates the login gate behind a single
session predicate with content-negotiated unauthenticated responses.
No behavioural change for logged-in users. The visible changes are: (a) new
canonical URLs; (b) old URLs now advertise their successor via headers; and
(c) unauthenticated API/tooling calls get a clean
401instead of beingredirected into login HTML.
What changed
Canonical routes (new)
GET /rest/v1/auth/loginGET /rest/v1/auth/userGET /rest/v1/auth/callbackGET /rest/v1/auth/logoutDeprecated aliases (old paths — behaviour preserved, header-only)
/rest/v1/login,/rest/v1/user,/rest/v1/callback,/rest/v1/logoutstillwork and delegate to the canonical handlers, but now return:
Deprecation: trueLink: <…canonical…>; rel="successor-version"They are header-only — no redirect to the canonical path (notably
/callbackstill completes the OAuth flow and lands on/chatbot), so existingintegrations don't break during the migration window.
Single login predicate + content negotiation
_is_logged_in()— the one source of truth, keyed onsession['user_id'](recorded by the login flow since feat(db): persist users + resource selection — Part of #586 #980), not

?next=from the browser auth challenge.
auth_loginnever consumed a return targetand
auth_callbackalways lands on/chatbot, so forwardingrequest.full_pathwas a dead (and taint-flagged) value. The challenge now redirects to the
constant
/rest/v1/auth/login; the unused_safe_nexthelper was dropped.(Return-to-page is a possible future feature via a session-stored target.)
redirect_uripointed at the deprecated route:CREFlow.instancenow builds the redirect URI from
url_for("web.auth_callback")(canonical)instead of
url_for("web.callback")(deprecated alias).fails explicitly instead of redirecting as if login succeeded — it aborts
503whenupsert_userraisesSQLAlchemyError, and401when the providerreturns no
sub. Previously these logged and redirected to/chatbotwithoutsetting
session['user_id'], so the nextlogin_requiredcall returned401and the chatbot bounced the user back into an endless login flow.
OpenAPI guardrail — resolved: EXEMPT
The four canonical
/rest/v1/auth/*routes are OAuth/redirect endpoints, notpart of the documented read-only public API. They are added to
OPENAPI_GUARDRAIL_EXEMPT_RULESinapplication/web/openapi_registry.py,alongside their already-exempt deprecated aliases — no PathSpecs and no
openapi.yamlregeneration. This clears the guardrail's route-coverage check(which was failing both the "Test" and "Lint Code Base" jobs).
/callbackalias)Because the OAuth
redirect_urinow resolves to/rest/v1/auth/callback, thatcanonical URI must be registered in the Google OAuth console before the old
/rest/v1/callbackalias is removed.Tests
auth_routes_test.py(new) — canonical routes, deprecated aliases carry thedeprecation headers, the
user_idpredicate, theNO_LOGINbypass, the fullcontent-negotiation matrix (
text/html → 302, multi-value browser→ 302,application/json → 401,*/* → 401, no-Accept → 401), anonymousPOST /rest/v1/completion → 401, and the callback failure paths(persistence-failure
→ 503, missing-sub→ 401, no-nextredirect).admin_imports_api_test.py— added/admin/**/* → 401and no-Accept → 401cases; existing admin tests unchanged.
