routes as before and report links whose destination page lacks the fragment id.

audit: decode escaped characters, skip routes containing a `Classes` segment,
and resolve `/en/` routes through `paths.ResolveRoute` using `versions`,
comparing the resolved `PublicUrl` so valid `.md` links are recognized.

The test no longer checks #section links.
The new check compares only target.AbsolutePath with the page routes. It ignores target.Fragment. A link such as page#missing-heading passes if page exists. A same-page link such as #typo resolves to the current route and always passes. The test name is AllDocumentationLinksResolveToExistingPagesAndSections, and the earlier code checked destination fragments. Broken section anchors can now reach production without a test failure. After the route lookup, look up the destination page. If the link has a fragment, check that the page contains an element with that id.
🐛 Proposed fix
var target = new Uri(new Uri("http://localhost" + key.Route), href);
var route = target.AbsolutePath;
- if (!pages.ContainsKey((key.Version, route)) && !pages.Keys.Any(p => p.Route.Equals(route, StringComparison.OrdinalIgnoreCase)))
+ var destKey = pages.ContainsKey((key.Version, route))
+ ? (key.Version, route)
+ : pages.Keys.FirstOrDefault(p => p.Route.Equals(route, StringComparison.OrdinalIgnoreCase));
+ if (destKey.Route == null)
{
errors.Add($"Broken link in version {key.Version} at {key.Route}: {href} (resolved to {route})");
+ continue;
}
+ var fragment = Uri.UnescapeDataString(target.Fragment.TrimStart('#'));
+ if (fragment.Length > 0 &&
+ pages[destKey].DocumentNode.SelectSingleNode($"//*[@id='{fragment}']") == null)
+ errors.Add($"Broken anchor in version {key.Version} at {key.Route}: {href}");Based on learnings: a fragment link to an id that does not exist "silently fails to scroll", so the code must check that the target id exists.

Normalize Markdown routes and skip generated class-reference routes.
DocRendererService converts class_* links to /en/{version}/Classes/..., but this audit only adds Markdown pages to pages. It also reports valid .md links as broken because it compares the suffix against PublicUrl, which omits it. Decode and resolve /en/ routes before comparing, and skip class-reference routes.
