Jan 1, 2026January 2026 focused on delivering business-value features, hardening stability, and improving user experience for Vision Zero. Key work included FRB recommendation statuses enhancements (new options and sort order), dynamic improvements to diagram rendering (dynamic y1 for diagram bbox), and major OCR/UI refinements for crash diagrams. Stability and data integrity were improved by removing cascade sequence handling to fix cascading issues, reverting test-file logic to maintain test stability, and addressing generic error handling. Documentation and terminology cleanup across CR3/Crash Report/CR4 references improved clarity, while UX improvements (PDF export in crash details) and activity logging for fatalities map toggle enhanced operability and observability. Ongoing work on CR4 diagram extraction shows active progress.
