February 2026 monthly summary for shirasagi/shirasagi. Delivered major CMS stability and capability improvements, refined GWS workflows and data integrity, and enhanced build/test throughput. Key changes include replacing query methods with find in CMS, enabling title edits during trash restoration and when duplicating folders, and truncating long CSV values. In GWS, files can be renamed on trash restore, and folder deletion now moves contained items to Trash with updated total counts on folder moves. The workflow was streamlined with a unified approver selection, and overall build/test concurrency was increased to 12, accelerating feedback cycles. We updated Mongoid and dependencies, refreshed the MongoDB GitHub Action, and introduced JSON-formatted API errors along with a privilege escalation fix. Additional code quality improvements include refactoring t/tt, standardizing object creation (.create), and prefixing GWS to job names.
