Catalog reference
Every check Wrendex runs lives in the catalog with a 'what / why / how to fix' guide.
Browse the catalog
The full list lives at /catalog. Each entry links to /catalog/<marketing-id>, which has the per-check 'what it is, why it matters, how Wrendex detects it, how to fix it' content. The same content backs the 'Learn more' link inside the dashboard.
Severities
Three severity levels: error (the check actively damages indexability or user experience), warn (the check degrades the audit but does not block it), info (the check is informational). Alert rules can match on severity directly.
Categories
Twenty-two categories: HTTP Status, Redirects, Canonicalization, Title Tags, Meta Description, Headings, Indexability, Content Quality, Structured Data, Hreflang, Open Graph, Twitter Cards, Internal Links, External Links, Sitemap, Robots, Mixed Content, HTTPS, JavaScript, CSS, Media, Performance. Categories are stable; checks within them grow.
