Worked on the coleam00/archon repository to deliver a Global Workflow Editing API Enhancement, introducing a 'source' parameter that allows workflows to be saved or deleted at either global or project scope. The implementation involved updating the API’s routing and schema logic using TypeScript and JavaScript, ensuring accurate handling of PUT and DELETE operations. Comprehensive validation tests were added to handle invalid source values, returning appropriate error responses and closing coverage gaps. Documentation and API references were updated to reflect the new behavior, while expanded test coverage and schema alignment helped prevent scope-related regressions and improved maintainability of the codebase.
