Looking good - we will need to discuss whether we store the aggregated data inside the database or if they should be saved as json files, mainly for easy archiving/compression at the end of the semester

Can you also fix the merge conflicts so i can run the tests? - I recommend to just rollback the migration via rails db:rollback, pull the latest schema changes, then start a new migration so that you have a newer migration timestamp, then re-run the migration with the requested changes (removing foreign key)

Overall workflow is looking really good

Just a few notes about bringing back the task status names, and querying the student's campus so we can bring back the campus filtering in the front end

Can you also please fix the RuboCop errors in the gh actions?
