Pin each browser session to the deployment that served it, so a long-lived dashboard session never 404s on a lazily-loaded chunk or changes version mid-session. Session cookie (no expiry) → next visit gets latest. - vite.config: inline VERCEL_DEPLOYMENT_ID + VERCEL_SKEW_PROTECTION_ENABLED. - router.tsx (TanStack-only): set a session __vdpl cookie scoped to BASE_PATH on client boot (platform + skew-enabled only); plus a vite:preloadError backstop that clears the pin and reloads if a chunk 404s (e.g. the pinned deployment aged out), with a time-window guard against reload loops. - deployment-commit-query: fetch the version-check endpoint with credentials:'omit' so the __vdpl cookie isn't sent and the edge serves the LATEST deployment — the update popup keeps detecting new versions while the session stays pinned. Stays on the basePath URL (root /api is the marketing site in prod). - use-check-latest-deploy: the Refresh button clears __vdpl before reloading so it lands on latest (no-op on the Next build, which sets no cookie). Requires enabling Skew Protection + System Env Vars in the Vercel project, and a Maximum Age comfortably above typical session length.
