Worked on the dstl/Stone-Soup repository, focusing on documentation and licensing improvements using Python and RST. Addressed licensing compliance by updating the copyright year across multiple files, ensuring all documentation and legal references aligned with the 2025 release cycle. This non-functional change reduced compliance risk without affecting runtime behavior. Additionally, performed maintenance on the Particle Tracker documentation, removing redundant sections to enhance clarity and maintainability. These efforts improved repository hygiene and prepared the project for future development. The work demonstrated attention to detail in documentation standards and licensing accuracy, contributing to the overall quality and sustainability of the codebase.
