Worked on the Submitty/Submitty repository to implement enforcement of non-zero prerequisite point thresholds for gradeable items, ensuring that access controls reflect required progress before unlocking assignments. Developed and configured a test environment using YAML, introducing a locked_homework_points threshold and corresponding Cypress end-to-end tests to validate access both before and after the threshold is met. Addressed an autograding threshold enforcement bug, closing a tracked issue and expanding automated test coverage to prevent future regressions. Focused on strengthening the testing infrastructure and continuous integration readiness, leveraging skills in Cypress, end-to-end testing, and YAML to improve reliability and reduce production risk.
