Worked on the cosmos/cosmos-sdk repository to enhance documentation security by updating external links in the Code of Conduct and architectural decision records from HTTP to HTTPS. This change focused on reducing the risk of insecure references and improving the overall governance of project documentation. Using Markdown and leveraging skills in documentation and link management, the developer ensured that contributors and users could navigate critical documents more safely. The update was tracked with explicit commit references, supporting traceability and alignment with security standards. No bug fixes were required during this period, as all efforts centered on strengthening documentation consistency and security posture.
