Metadata
Every HTML page should have a title, meta description and canonical URL.
Automated checks
What the validator protects
Structure
Every page should have exactly one H1 so search engines and screen readers understand the page.
Internal links
Internal links are checked against repository routes to catch broken navigation before merge.
Required scripts
Core enhancement and routing scripts are checked so the experience stays consistent.
Decision tool continuity
Decision Navigator, saved Decision Brief context and Readiness Assessment handoff should keep working together.
Sitemap coverage
Important pages should appear in the sitemap so discovery does not depend on luck.
Workflow
When the checks run
The validator runs on pull requests, pushes to master and manual workflow dispatch. If a quality gate fails, the fix should happen before the page is treated as complete.
