Fetcher.Allowed and Key, the rendered comparison and the Chrome request
guard accept an address only on the site's effective port (explicit,
else 443 for https and 80 for http), so page code cannot make headless
Chrome reach other services on the site host's address and a link to
another port is not reported as a page of the site.
- jsonld_invalid, jsonld_multiple, and jsonld_required/recommended from
schema.Validate (the E9 rules); publisher nodes route to settings
- hreflang_error and hreflang_reciprocal over the fetched alternates
- broken_link and redirected_link with the linking pages, generic_anchor
against the en and pl seed lists
- image_alt, image_size and featured_lazy
- content_js check cms: the record title in the H1, half its words and
its primary parent's link in the raw HTML
- compareRendered (pure): links, an H1 or text only after JavaScript as
content_js check rendered; the Renderer seam and render bookkeeping
- TestRenderSkipped: skipped without a renderer, failed with its note
