Descope JWT role changes only appear after refresh, use introspection
Never treat a locally validated session JWT as live authorization data. After changing a user's roles, tenant, or custom attributes, either force a session refresh so the new claims land in the token, or call the UserInfo endpoint (token introspection) on the requests where freshness matters. Keep local JWT validation for the authentication check, and put the authorization check behind introspection or a fresh refresh. Note introspection is a remote call per request, so scope it to the routes where roles actually gate access.
Context: Official docs (Session Validation): documents a gotcha that trips agents doing authorization from JWT claims. Descope session tokens are validated locally with cached public keys, which is fast, but roles, tenant, and custom claims in the JWT are only as fresh as the last refresh. The docs say to use token introspection via the UserInfo endpoint in addition to local JWT validation when you need live claims on every request. An agent that grants a role and then re-reads the same session JWT will see the old roles and conclude the grant failed.Maintainer review
