Web content conforms to WCAG 2.1 guideline 2.4: repeated blocks can be skipped, pages have descriptive titles, focus order is logical, link purpose is clear in context, more than one way exists to find pages, headings and labels describe their content, and keyboard focus is visible (2.4.1 to 2.4.7).
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
