Automated excerpt
What __exportAll actually is It's a bundler helper. The module is already in the bundle, already loaded, already reachable through the static import. The branch's own preview deployment builds the branch tip. Read the built SSR output as an import graph and fail if a chunk that defines or imports the helper sits on an import cycle. If you fail the build on "helper found", you'll fail every build.
