Contributed to the ocsf-schema repository by expanding its HTTP modeling capabilities through the addition of PATCH method support within the http_request and Http Activity components. Focused on schema development, the work involved updating the Markdown-based documentation and CHANGELOG to accurately reflect these enhancements. The implementation maintained backward compatibility, ensuring existing integrations remained unaffected while enabling the schema to represent a broader range of REST-like HTTP patterns. This targeted feature improved interoperability for clients and services relying on PATCH semantics, demonstrating a careful, minimal-change approach to evolving the schema. No bug fixes were required during this period, reflecting stable project maintenance.
