Apr 1, 2025April 2025 monthly summary for freelawproject/courtlistener: Delivered robustness and reliability improvements to the citations pipeline. Fixed crash when opinions have no citations by ensuring proper HTML generation and saving, and hardened the citations-management find_citations command by enforcing opinions-per-task as an integer with a default of 100, reducing type-related errors and standardizing configuration. These changes enhance data integrity for opinions and citations, improve downstream search and analytics accuracy, and reduce manual intervention.
