Reusable checks for problems I kept fixing across sites.

I kept running into the same classes of problems on different sites: broken internal links, inconsistent canonical URLs, stale assets, duplicate IDs, redirect regressions, and small changes that caused issues elsewhere. Instead of solving those from scratch on each project, I moved the reusable checks and helpers into one repository.

• Broken internal links, missing fragment targets, orphan pages, redirect chains, and duplicate redirect sources.
• Canonical and Open Graph URL consistency, sitemap coverage, duplicate IDs, labels, JSON-LD, and missing assets.
• Unfinished placeholder copy and broad repeated long-form content that can indicate template regressions.

• Generates sitemap.xml, robots.txt, security.txt, Cloudflare redirects, security headers, and a build-health report.
• Fingerprints CSS and JavaScript with content hashes so long-lived caching can be used without serving stale assets.
• Runs npm run verify locally and in GitHub Actions, with a separate live audit for redirects and deployment headers.
