data.healthcare.gov: Accessibility — week 2026-W38

Automated Accessibility Conformance Report (OpenACR): Download ACR. Machine-readable; compatible with GSA OpenACR tooling. Automated tools find ~⅓ of real barriers — supplement with manual AT testing.

Training priorities

Top WCAG success criteria by pages affected this week. Use these to focus team training on the highest-impact issues.

SC	Criterion	Pages	Rules
1.4.6	WCAG 1.4.6	723	1
1.4.8	WCAG 1.4.8	723	1
2.5.5	WCAG 2.5.5	723	1
4.1.2	Name, Role, Value (ARIA)	623	2
2.5.3	WCAG 2.5.3	4	1

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.

Top 10 clustered component fixes for this week.

Bug reports

4 issue type(s) are shown by default out of 20 total. Prioritized by severity, key pages, WCAG level, and prevalence; use the toggle to show everything.

Overall severity mix: 3 serious, 16 moderate, 1 minor. By WCAG category: 4 WCAG 2.0 A, 1 WCAG 2.0 AA, 1 WCAG 2.1 A, 3 WCAG 2.x AAA, 6 Best Practice, 5 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 4 prioritized issue type(s); 16 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.

Affected pages

/AB-NIPR-Health-Line-Of-Authority

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.

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.

Unique issues (rule × page): 2832
Caught by both engines: 0 highest confidence
axe only: 23
Alfa only: 2809

No issues were flagged by both engines on the same pages this week.
