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 / medicare). ds-c-drawer: 200% of sampled rule findings · ds-c-button: 200% of sampled rule findings · ds-c-help-drawer: 100% of sampled rule findings · ds-c-fieldset: 49.9% of sampled rule findings · ds-c-card: 2.3% of sampled rule findings

Bug reports

7 issue type(s) are shown by default out of 21 total. Prioritized by severity, key pages, WCAG level, and prevalence; use the toggle to show everything.

Overall severity mix: 3 serious, 17 moderate, 1 minor. By WCAG category: 3 WCAG 2.0 A, 2 WCAG 2.0 AA, 1 WCAG 2.1 A, 4 WCAG 2.x AAA, 5 Best Practice, 6 Undetermined. Ordered by severity, key-page impact, WCAG level, and prevalence. Following accessibility bug-reporting best practices. 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 7 prioritized issue type(s); 14 more are available if you switch to "Show everything".

1 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.

Description

Elements must meet minimum color contrast ratio thresholds. Detected by axe-core rule color-contrast on 1 of 2061 scanned pages (4 instances).

Steps to reproduce

  1. Open https://www.medicare.gov/basics/costs/help/medicare-savings-programs.
  2. Locate the element: .table-wrapper:nth-child(4) > table > thead > tr > th:nth-child(3) > .help-drawer[data-drawer-id="109301"][data-size="std"] > .ds-c-drawer__toggle.ds-c-drawer__toggle--inline.ds-c-help-drawer__toggle
  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.

<h3>Polish</h3>

Description

Heading levels should only increase by one. Detected by axe-core rule heading-order on 43 of 2061 scanned pages (43 instances).

Steps to reproduce

  1. Open https://medicare.gov/publications/search/all-non-english-pubs?page=4.
  2. Locate the element: .layout__column.ds-l-col--12 > h3:nth-child(1)
  3. Confirm the axe-core finding for rule heading-order.

Impact

Not captured by automated scan — requires manual testing.

Affected pages

…and more — all 43 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: Use heading levels in order (h1 → h2 → h3) without skipping; structure, not size.

Drupal tip: Drupal Views and blocks can insert headings at arbitrary levels. In the Views UI, set "Title tag" for each display. For block titles, configure the heading level in the block's layout settings.
