May 1, 2025

May 2025 delivered a robust upgrade to the project and time-tracking platform with a focus on cross-project time management, data integrity, and UI polish. Key features include a cookie overflow guard with a vote counter, multi-project support with an Arcade/juice timer and per-project time tracking, and Hackatime integration for data pull, project selection, and manual sync. We also implemented an immutable project category to preserve data integrity, added a timer visualization, and enforced a 5-minute minimum timer limit. Major reliability fixes addressed timer/session integrity (stopped timers, session linking, TimerSession IDs), prevented mis-linking of updates to timer sessions, and corrected deletions under foreign key constraints. Additional maintenance work updated dependencies, ran linting, and migrated UI styling to Tailwind for consistency and performance. The result is more accurate cross-project time data, stronger data integrity, and a smoother, scalable developer experience across projects.

December 2024 performance summary for hackclub/high-seas: Delivered a user-facing maintenance banner to gracefully handle ongoing work. Implemented a 'Battles Temporarily Paused' notice that renders conditionally based on the 'tutorial' sessionStorage flag, hides the standard battle UI and voting elements during the pause, and clearly communicates that rating recalculations and payout fixes are in progress. This change reduces user confusion during maintenance and preserves engagement while backend work proceeds. Linked to commit 47cf12ec813011645399020293a3e6156682b1d4 ('Pause matchups') to enable traceability and quick rollback if needed.
