Next 10 actions

Clusters are fingerprinted by normalized selector path + rule id + snippet shape. Rank score = (severity weight × pages affected) / distinct components for the rule. This supersedes the template threshold heuristic while still surfacing it as a validation signal.

Design-system alignment (cms-ds / default). No design-system components detected in sampled findings.

Overall severity mix: 3 critical, 7 serious, 27 moderate, 2 minor. By WCAG category: 15 WCAG 2.0 A, 4 WCAG 2.0 AA, 1 WCAG 2.2 AA, 3 WCAG 2.x AAA, 9 Best Practice, 7 Undetermined.

Download: Markdown · JSON (full archive) · JSON (AI diagnostic) · CSV (all findings) · Priority pages CSV · Priority pages JSON.

Automated testing does not establish full WCAG conformance. Findings in the verification lane require manual testing before they are treated as confirmed failures.

Default view shows 14 prioritized issue type(s); 25 more are available if you switch to "Show everything".

3 finding(s) marked "possible duplicate" — Alfa and axe-core both flagged the same WCAG SC on overlapping pages. If they target the same element, the axe-core report is authoritative. Filter the CSV by possible_duplicate_of to see these. Two engines flagging the same barrier reduces the chance of a false positive.

Findings needing review

These findings need manual verification before they can be treated as confirmed failures. Obligation remains visible for each finding.

<html>

Description

<html> element must have a lang attribute. Detected by axe-core rule html-has-lang on 305 of 4664 scanned pages (305 instances).

Steps to reproduce

  1. Open http://www.cms.gov/icd10m/FY2023-version40.1-fullcode-cms/fullcode_cms/P0093.html.
  2. Locate the element: html
  3. Confirm the axe-core finding for rule html-has-lang against WCAG 3.1.1 Language of Page.

Impact

Affects Without vision (1.0%), Limited cognitive, language, or learning ability (11.0%).

  • Without vision — 1.0% of population
  • Limited cognitive, language, or learning ability — 11.0% of population

Affected pages

…and more — all 305 pages (CSV).

Testing environment

Automated: axe-core, headless Chromium (Playwright). Manual AT verification: Not captured by automated scan — requires manual testing.

Suggested fix

How to fix: Add a lang attribute to <html> (e.g. lang="en").

Drupal tip: Drupal sets the page lang attribute from Admin › Configuration › Regional and Language › Languages. Ensure the default language is configured.

Affected pages

…and more — all 294 pages (CSV).

Testing environment

Automated: axe-core, headless Chromium (Playwright). Manual AT verification: Not captured by automated scan — requires manual testing.

Suggested fix

How to fix: Give every <img> a meaningful alt attribute. Use alt="" only for decorative images so screen readers skip them.

Drupal tip: In Drupal's Media Library, fill the "Alternative text" field when uploading or editing an image. For images in body fields, the CKEditor "Image Properties" dialog includes an Alt Text field.

  • Without vision — 1.0% of population
  • Limited vision — 2.4% of population
  • Limited manipulation/strength — 13.0% of population

Affected pages

Testing environment

Automated: axe-core, headless Chromium (Playwright). Manual AT verification: Not captured by automated scan — requires manual testing.

Suggested fix

How to fix: Associate every form control with a <label> (via for/id) or an aria-label/aria-labelledby.

Drupal tip: Use Drupal's form element "Label" setting. In Webform, every element has a Label field — ensure it's not empty or hidden. Check that twig templates don't strip <label> elements from form fields.

Description

Elements must meet minimum color contrast ratio thresholds. Detected by axe-core rule color-contrast on 34 of 4664 scanned pages (510 instances).

Steps to reproduce

  1. Open https://www.cms.gov/medicare-coverage-database/view/lcd.aspx?areaId=all&bc=1&contractOption=all&docType=F&keyword=psych&keywordType=all&lcdid=39464&sortBy=relevance&ver=7.
  2. Locate the element: td[rowspan="2"]:nth-child(1) > p
  3. Confirm the axe-core finding for rule color-contrast against WCAG 1.4.3 Contrast (Minimum).

Impact

Affects Limited vision (2.4%), Without color perception (4.5%).

  • Limited vision — 2.4% of population
  • Without color perception — 4.5% of population

Affected pages

Testing environment

Automated: axe-core, headless Chromium (Playwright). Manual AT verification: Not captured by automated scan — requires manual testing.

Suggested fix

How to fix: Increase the contrast between text and its background to at least 4.5:1 (3:1 for large text). Check both light and dark modes.

Drupal tip: Check your Drupal theme's base CSS. Themes like Olivero and Bartik have contrast issues in default color schemes — override failing color pairs in your subtheme's style.css.

Affected pages

Testing environment

Suggested fix

How to fix: Give the link discernible text. Avoid empty links and icon-only links without an aria-label.

Drupal tip: "Read more" links from Drupal Views should use the "Link text" rewrite field to add context, or add aria-label via the Views rewrite output.

Description

Landmarks should have a unique role or role/label/title (i.e. accessible name) c. Detected by axe-core rule landmark-unique on 3 of 4664 scanned pages (3 instances).

Steps to reproduce

  1. Open http://www.cms.gov/Newsroom/MediaReleaseDatabase/Fact-sheets/2015-Fact-sheets-items/2015-07-08.html.
  2. Locate the element: .views-field-field-topic[aria-label="Related search topics"][role="region"]:nth-child(1)
  3. Confirm the axe-core finding for rule landmark-unique.

Impact

Not captured by automated scan — requires manual testing.

Affected pages

Testing environment

Automated: axe-core, headless Chromium (Playwright). Manual AT verification: Not captured by automated scan — requires manual testing.

Suggested fix

How to fix: When a landmark role/type repeats (e.g. two <nav>s), give each a distinct accessible name with aria-label or aria-labelledby (e.g. "Primary" and "Footer" navigation) so screen-reader users can tell them apart.

Unique accessibility issues (axe + Alfa consolidated)

axe and Alfa both implement W3C ACT rules, so the same issue is often caught by both. These are deduplicated by ACT rule and page, so a shared finding counts once (5526 raw engine findings → 5357 unique).

6 rule type(s) caught by both engines — highest confidence

Two independent ACT-rule implementations (Deque axe-core and Siteimprove Alfa) flagged the same issue on the same pages. Agreement between separate engines is strong evidence the barrier is real, not a single-tool false positive — the best place to start.

Rules flagged by both axe-core and Alfa in 2026-W38, by pages affected.
