Worked on the lockss/lockss-daemon repository to address data integrity by implementing an archival unit status correction within the TDB data. Focused on configuration management and data management, the developer updated the status of several archival units from 'released' to 'down' across multiple journal entries to accurately reflect their unavailability. This targeted change improved the accuracy of availability reporting and reduced confusion in monitoring dashboards, ensuring that the data state matched real-world access. The work was delivered as a focused, low-risk bug fix with clear, traceable commit messaging, demonstrating attention to auditability and minimal disruption to the existing system.
