Definition
Open-source SEO crawler notes on the site, based on public observation of puneetindersingh/open-seo-crawler under the MIT license, mention titles, sitemaps, hreflang, duplicates, broken links, noindex via meta robots or X-Robots-Tag, status codes, canonicals, and soft 404s. That list is a coverage map, not a scoreboard, and it does not mean the project documentation was copied.
Short answer
The notes mention titles, sitemaps, hreflang, duplicates, broken links, noindex via meta robots or X-Robots-Tag, status codes, canonicals, and soft 404s. They are a coverage map from public observation of that MIT-licensed crawler, not a scoreboard and not a copy of its documentation.
What to check

What this does not claim
A crawler coverage map does not guarantee healthier rankings or that every issue will be found. Mika does not guarantee search rankings or AI answer citations, and these notes do not claim the open-source documentation was copied.
A practical example
A note can record that one URL has a title, appears in a sitemap, and sends hreflang, while another is marked noindex through meta robots or X-Robots-Tag. The same coverage map can include duplicates, broken links, status codes, canonicals, and soft 404s without turning the crawl into a scoreboard.
