Developed and delivered a comprehensive SECURITY.md for the input-output-hk/partner-chains repository, establishing a formal security policy, outlining supported versions, and defining a structured vulnerability reporting process. Focused on enhancing security governance and documentation, the work improved transparency and provided clear guidance for both internal teams and external stakeholders. Leveraged Markdown for precise documentation and applied policy drafting skills to ensure clarity and completeness. The approach emphasized cross-team collaboration and release governance, resulting in a stronger security posture and improved readiness to address vulnerability reports. No bug fixes were addressed during this period, with efforts concentrated on documentation and security policy.
