Pull request overview
This PR enhances W3C header handling by adding validation/verification around key header links (notably latestVersion and historyURI) and extends the test suite to cover the new behaviors, aiming to surface broken header links earlier via warnings/errors.
Changes:
- Add a HEAD check for derived
latestVersionURLs and emit aw3c/headerswarning when the URL can’t be reached. - Adjust
historyURIderivation to support explicit suppression (null) and refactor URL probing intoresourceExists(). - Update/extend
w3c/headerstests (warnings filter, status loops, new warning expectation).

src/w3c/templates/cgbg-headers.js:47
conf.latestVersion !== null(and the nestedconf.latestVersion !== "") will treatundefinedas “present” and render an<a>whose href/text becomeundefined. The W3C headers template avoids this by checking property existence ("latestVersion" in conf) and then treating falsy values as “none”. Consider aligning the CGBG template logic (e.g., guard on property existence or use a nullish check) so missing/undefinedlatestVersioncan’t produce a broken link.
${conf.latestVersion !== null
? html`<dt>${l10n.latest_published_version}</dt>
<dd>
${conf.latestVersion !== ""
? html`<a href="${conf.latestVersion}"
>${conf.latestVersion}</a
>`
: "none"}
