Software meets the software version of WCAG 2.1 guideline 1.4: no colour-only cues, audio control, text and non-text contrast, resizable text (or 6.1.4 where closed), avoiding images of text, reflow, text spacing where layout permits, and dismissible hover or focus content.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
