Thibault enhanced the SCITT architecture diagram in the ietf-wg-scitt/draft-ietf-scitt-architecture repository, focusing on clarifying the roles of Issuer, Relying Party, and Auditor. Using Markdown and technical writing skills, Thibault updated terminology, refined the diagram’s layout, and improved typographical consistency to ensure the visuals matched the textual definitions. The work addressed reviewer feedback through multiple iterations, resulting in a more accurate and usable Figure 1. By aligning diagram elements with the architecture’s documentation, Thibault reduced ambiguity and supported clearer communication for reviewers. The depth of the changes demonstrated careful attention to both technical accuracy and documentation quality.
