+## Current Progress
+
+- Migrated the site and administrator modules to the Joomla 5 service-provider structure (manifest, dispatcher, helper, templates).
+- Removed legacy module entry scripts from the manifest so packaging now relies on the DI dispatcher flow.
+- Registered the `server` view in the site router to restore the CAS login redirect endpoint after modernization.
+
+## TODO
+
+- Verify the frontend CAS Login link end-to-end once the dev container stack is running (expects redirect to the configured CAS server and back).
+- Confirm extension update scripts clean up leftover legacy files on existing installations.
+- Run module smoke tests in Joomla backend/frontend after packaging to ensure no regressions in alternative layouts.
