## Changelog

### 0.1 (2026-10-26)

First release.

- Quick mode: per page the final URL, status and redirect chain, server response time, 48 SEO
  checks on the page source and headers with evidence, a plain-English fix and an "ask your
  developer" version, ranked by impact, and a Quarrywise SEO check score.
- Technology detection from our own MIT fingerprint set (about 300 technologies) with confidence,
  version and evidence; third-party scripts grouped by vendor; likely leftovers (failed, retired,
  risky or duplicated scripts); scripts blocked by the site's own Content-Security-Policy reported
  as blocked (from the policy header, and from the browser in a lab run), never as leftovers.
- Full mode: Lighthouse 13 in headless Chrome, mobile and/or desktop, 1 to 5 runs per device
  reported as median, lowest and highest value and labelled as lab data; Core Web Vitals lab
  metrics, opportunities, failed audits, per-vendor bytes and main-thread time, and 9 lab checks.
- Sitemap discovery (robots.txt and /sitemap.xml, indexes and gzip) up to 500 pages per site;
  cross-page checks for duplicate titles and descriptions and hreflang return links; robots.txt
  report of search and AI crawler access.
- Budgets with pass or fail per page; change detection per watch ID that separates real changes
  from normal lab variation.
- Site summaries in the OUTPUT record and a Markdown REPORT record; optional Markdown per row.
- Pay per event: per page checked and per completed Lighthouse run; pages that cannot be checked
  and failed runs are free.
- Polite lab runs: Lighthouse page loads of one site at least 5 s apart (longer with a robots.txt
  Crawl-delay), at most 30 per site per run, and the QuarrywiseBot token on every browser request.
