March 2026: Delivered a security-focused enhancement in hmcts/em-native-pdf-annotator-app by implementing object-level authorization for redaction deletion. The feature ensures only the redaction creator can delete a redaction, with comprehensive tests covering ownership checks and edge cases (user not found, user not owning the redaction). The change improves data integrity and reduces risk of unauthorized deletions. Notable coordination with the team culminated in a co-authored commit (EM-7001) addressing missing authorization with PR #2949.
