Worked on the METR/vivaria repository to address a targeted issue in the Inspect Importer, focusing on backend development using Node.js and TypeScript. Delivered a bug fix that enabled the importer to correctly process samples flagged for manual scoring by storing a null score and bypassing standard numeric validation. This adjustment ensured that samples requiring manual review were ingested without triggering downstream errors or requiring additional manual intervention. The solution was implemented with minimal changes to the existing codebase, maintaining code clarity and reliability. Comprehensive end-to-end testing validated the new manual scoring path, reinforcing data integrity and supporting robust ingestion workflows.
