The shared site check let a few broken pages through and crashed on one kind of bad link. A self-closed <textarea/> hides the rest of a page in a browser, because HTML ignores that slash, but the check read it as empty. A %00 in a link path stopped the check with a traceback instead of an error line. A theme.features string, a redirect_maps that is not a table, a site URL without a scheme, or a home page with no content block passed without a word.

What changes: .github/scripts/site-check.py (and, on a list, docs/hooks/awesome_site.py) is the new shared copy. Each case above is now an ERROR line; a redirect stub is recognised by its parsed title, and the list's include line may use either quote and CRLF line endings.

Verified: planted controls on a real build, each new rule red before and green after the fix, with the error message checked; all 58 sites in the fleet build and check clean with it.

Summary by CodeRabbit

• Bug Fixes
  • Site checks now more accurately identify redirect pages and handle HTML void elements, SVG/MathML tags, and self-closed text areas.
  • URL validation now flags invalid site addresses and malformed paths, and handles resolution errors consistently.
  • Configuration checks now report invalid feature lists and redirect maps, and verify that the home page is a content page.

Walkthrough

The site checker now parses redirect titles from head content, applies HTML void-element rules to self-closing tags, validates site URLs and paths, checks configuration values, and requires index.html to be a content page.

Changes: Site checker

Layer / File(s)	Summary
HTML parsing and page identity .github/scripts/site-check.py	The parser tracks head-title text and identifies redirect stubs by comparing the trimmed title with Redirecting.... Self-closing tags count as empty only for HTML void elements or tags in SVG and MathML.
Site URL and path resolution .github/scripts/site-check.py	The checker requires an absolute HTTP(S) URL with a hostname. It derives a directory prefix from canonical links ending in .html, rejects decoded NUL paths, and returns BAD when path resolution raises OSError or ValueError.
Configuration and content-page checks .github/scripts/site-check.py	The checker validates theme.features and redirect_maps, and reports an error when index.html is absent from the collected content pages.

Some malformed site configuration passes the check without an error. These are narrow validation gaps that should be fixed, but they do not prevent merging.

Review comments at @.github/scripts/site-check.py:
- Line 437: Update the redirect_maps lookup in the redirects validation flow to
use an empty mapping only when the key is absent; preserve configured falsey
values so the existing type check rejects invalid values such as an empty string
or list.
- Around line 366-370: Update the `theme.get` call used to initialize `features`
so the empty-list default applies only when the key is absent, not when an
explicit falsey value is provided. Keep the existing list-of-strings validation
and error handling so values such as an empty string, false, or zero are
rejected.
