Accessibility

What was tested, what was not, and how to tell us when something is wrong.

Applies to kelvara.ai · last tested 12 September 2026 · each agent publishes its own statement

Conformance target

WCAG 2.2 level AA, plus the UK Public Sector Bodies (Websites and Mobile Applications) (No. 2) Accessibility Regulations 2018. The UK regulations are taken on deliberately: UK universities are public sector bodies, and a tool one of them procures can be pulled into scope. A statement written after that discovery is written under someone else's deadline.

What was actually tested

Claiming conformance for something nobody checked is worse than claiming nothing, so this list is narrow on purpose.

CheckedHowResult
Colour contrast, every declared token pairComputed from the stylesheet on every test runPass
No banned visual property in any stylesheetAutomated, in the test suitePass
Landmarks and a skip link on every pageRendered through Flask, in the test suitePass
Skip link is first in the DOM and visible on focusBy hand, 12 September 2026Pass
Colour is never the sole carrier of meaningEvery tier and state renders a word beside its colourPass
Reduced motion honouredThe one page-load animation is never declared for a reader who asked for less motionPass
Keyboard traversal and focus visibilityBy hand, 12 September 2026Pass
Layout at 400pxBy hand. Multi-column blocks stack at 860pxPass
Every internal link resolvesEvery template href checked against the route mapPass

The measured contrast table is deliberately not reproduced here. The test parses the real stylesheet and is the living version; a copy in prose would be a second home for the numbers and would drift. That has already happened on this project, in the same role, one design system apart.

Known limitations

These are real and are not claimed as conformant.

Screen readers

No screen reader testing has been performed. Landmarks, labels and a skip link are present and were checked structurally, but nobody has run these pages through NVDA, JAWS or VoiceOver. Structural presence is not the same as a usable announcement order.

Untested
Divider contrast

The divider token sits below 3:1 against the surface it separates. Deliberate: a rule between two blocks of text carries no information the text does not already carry, so it is outside SC 1.4.11. If a divider is ever made load-bearing, used alone to group or to indicate state, the exemption is void and the token must be raised.

Deliberate
Automated audit

No automated axe or Lighthouse run is in the test suite. The checks above are hand-written and targeted, and are not a substitute for a full automated audit.

Untested
Intermediate viewport widths

The homepage claim scales fluidly with the viewport. It was checked at 400px and at 1440px; widths in between were not checked individually.

Partial
Scope

This statement covers the hub only. Each agent runs its own code on its own subdomain and publishes its own statement, so a reader should not assume this result applies to any agent.

Reporting a problem

If something here is wrong, or an assistive technology cannot reach part of this site, please report it. Include the page, what you were using, and what happened. We aim to respond within five working days.

If you are not satisfied with the response, the UK enforcement route for public sector bodies is the Equality Advisory and Support Service (EASS).
