During January 2025, Arantius focused on improving the stability and accuracy of CWTV metadata extraction within the harry0703/yt-dlp repository. He addressed a persistent bug in the CWTV extractor by refining how video metadata is fetched through API integration and enhancing error parsing logic. Using Python and leveraging his expertise in data extraction and web scraping, Arantius improved the identification of series and episode numbers, ensuring more reliable content matching. He also updated the test suite to reflect these corrections, supporting regression safety and data correctness. This work enhanced metadata quality, reduced identification failures, and supported downstream processing reliability.
