April 2026: Strengthened reliability of the Claims for Crown Court Defence workflow by hardening claims handling and the unarchive restoration path. Delivered two critical robustness fixes: (1) guard against nil in the second state transition, and (2) a revamped unarchive flow that restores to the last non-archived state by walking PaperTrail versions. These changes reduce edge-case failures, improve data integrity, and shorten post-incident recovery time. Technologies/skills demonstrated include Ruby/Rails, defensive programming, PaperTrail versioning, and targeted refactoring with improved error handling. Business impact: fewer outages, more accurate restorations, and higher confidence in archival workflows. Commits: 27f0f8cc21cc9bd83d9e7603925c913e40a9a61b; 874730241fe3d7cf8fab74d01fdbb93effebff12.
