Worked on maintaining data integrity within the opensanctions/opensanctions repository, focusing on the fcib dataset’s configuration. Addressed a specific bug by correcting a typo in the tr_fcib.yml file, which previously risked misidentification or exclusion of records during downstream processing. This targeted fix improved the reliability and consistency of data curation and engineering workflows, ensuring that the dataset’s behavior remained stable across the pipeline. The work involved careful validation of YAML configuration changes to uphold data quality standards. No new features were introduced during this period, with efforts concentrated on sustaining robust data processing and accurate record matching.
