Each web page satisfies the five WCAG 2.1 Level AA conformance conditions: the level is met directly or by a conforming alternate version, whole pages and whole processes conform, technologies are relied on only in accessibility-supported ways, and nothing on the page interferes with use, even content not relied on keeping to the audio control, keyboard trap, pause and flash criteria.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
