feat: canonicalize old-version example pages to /latest - #1166
Conversation
Example pages now get the same treatment as docs pages: when serving an old version, check whether the same example directory exists on the latest branch (cached repo-contents lookup, resolved in parallel with the example fetch, fails open) and emit a rel=canonical (plus og:url/twitter:url) pointing at the /latest URL. The route takes over canonical ownership via staticData.ownsCanonicalLink like the docs routes. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
📝 WalkthroughWalkthroughThe framework example route detects matching examples on the latest branch. It propagates a canonical path override through loader data and uses it for canonical, Open Graph, and Twitter metadata. ChangesFramework example canonicalization
Merge Risk: 🟡 Moderate · up to Old-version example pages can publish conflicting social URL metadata, causing previews and shared links to reference the stale version instead of /latest. Merge should wait until these tags have a single consistent canonical URL. Sequence Diagram(s)sequenceDiagram

Suppress root URL metadata for this loader-owned canonical URL.
src/routes/__root.tsx still emits og:url and twitter:url when ownsCanonicalLink is true. On an old-version example page, the root emits the old-version URL and this head emits the /latest URL. This produces conflicting social URL metadata.
Extend the root suppression logic to cover loader-owned URL metadata, or use one metadata owner for these tags.
