Chetna Dudani developed preparatory scaffolding within the EC507/EC507 repository by initializing a placeholder demo.txt file in the assignments/24sema84 directory. This work focused on establishing a concrete artifact to support future feature development, enabling rapid prototyping and demonstration flows without impacting existing runtime behavior. Using Git for version control and standard file management practices, Chetna’s approach provided a maintainable foundation for upcoming content expansion and streamlined onboarding. No functional changes or bug fixes were introduced during this period, reflecting a depth of planning and attention to maintainability rather than immediate feature delivery, and setting the stage for future enhancements.
