The traffic timing test starts a Vite server rooted at the package, which
wrote its dependency cache to node_modules/.vite and kept writing after the
server closed. A host running Core's suite then finds files inside Core and
its check refuses them. The server now uses a temporary cache directory,
removed afterwards, and skips dependency discovery, which the SSR-loaded
modules never need.
The HUD place-lookup changelog note credits its PR, #1459.
