During September 2025, Sergio Pedrajas expanded taxonomy source support in the rosetta-models/common-domain-model repository by adding a new 'CFTC' value to the TaxonomySourceEnum. This enhancement focused on data modeling and enum definition using the Rosetta language, broadening the system’s ability to categorize and ingest taxonomy-related data. Sergio’s work was scoped to a single feature with a clear commit history, reflecting a targeted and maintainable approach. While no bugs were addressed during this period, the update improved downstream data processing and quality. The depth of the work was moderate, centering on schema extensibility and precise domain model evolution for asset data.
