In April 2025, Adam Adler enhanced the update_obsdb module in the simonsobs/sotodlib repository by implementing persistent tracking of bad book IDs, addressing data quality and recoverability in the processing pipeline. Using Python and leveraging data engineering and file I/O skills, Adam introduced a mechanism to record known_bad_books and enforced strict error handling when new bad books appeared with skip_bad_books enabled. This approach ensured that data issues surfaced promptly, reducing silent failures and manual debugging. The work improved traceability and reproducibility in the workflow, providing a robust foundation for future audits and more reliable data processing operations.
