Worked on the Quant_RUC repository to establish foundational infrastructure for future development and resource delivery. Introduced a test framework scaffold by adding a placeholder test file, setting up the groundwork for comprehensive quality assurance in upcoming sprints. Expanded the finance homework directory with a new PDF resource to support user learning, which involved file management without code modification. The technical approach emphasized maintainability and future extensibility, leveraging Python for test scaffolding and standard file operations for resource integration. No bugs were addressed during this period, as the focus remained on enabling faster validation and streamlined access to educational materials in subsequent cycles.
