Hannah refined the Archer class diagram for the pacalso-jjc/2425-2nd-cc3-1e-rpg repository, focusing on clear documentation and maintainability. She used Mermaid and Markdown to create a diagram that accurately represents the Archer class’s relationship to Classification, removing the HP stat to align with updated requirements and clarifying inheritance indicators for better architectural understanding. By correcting Markdown syntax, she ensured the diagram renders correctly, supporting onboarding and future development. The work emphasized diagramming and documentation skills, providing a precise, up-to-date reference for contributors. While the scope was focused, the changes improved clarity and reduced ambiguity without affecting runtime behavior.
