Counting rules: a publisher is counted once per citation at its registered domain, so every subdomain of one site lands on one row; the image hosts an answer cites alongside its pages are left out; each count reads a single surface at a single tier. Each section reports its [effective sources](https://luce.veliu.com/glossary.html#effective-sources) , the diversity figure behind the counts.
