Pages with a broken Markdown twin
A per-URL report: one row per page that matches, over the pages a crawl reached.
What this report returns
A Markdown twin is an agent-friendly plain-Markdown copy of a page, advertised with <link rel="alternate" type="text/markdown" href="...">.
These pages advertise one incorrectly: the type isn't text/markdown or the href is empty, so agents can't recognise or locate the twin they were promised.
How to fix it. Declare both halves: type="text/markdown" and an href pointing at the Markdown resource, e.g. href="/page.md".
The columns it shows
Every defect this technology can carry is a column in the grid, worst first, so nothing is hidden behind a filter you have to know to apply.
