The Vercel deploy 404'd at `/` because PR #75's `vercel-build` script (`scripts/build-vercel-output.mjs`) ran `rm -rf .vercel/output` and rebuilt it from `.output/public`. On Vercel CI, Nitro's Vercel preset auto-activates (from the VERCEL env var) and emits the Build Output API layout to `.vercel/output` itself during `vite build`; the script then clobbered that correct output with a static-only config that could not resolve the SPA `_shell.html` fallback or the server functions, so production returned `404: NOT_FOUND` even though the build was READY. Stop fighting Nitro and drive the proxy through it instead: - Remove `scripts/build-vercel-output.mjs` and the `vercel-build` script; restore the plain `vite build` for both local and Vercel builds. - Add an env-driven Nitro `routeRules` proxy in `vite.config.ts`. Nitro's Vercel preset compiles a plain external-URL `proxy` rule into a CDN-level rewrite in `.vercel/output/config.json` at build time, reading LANGGRAPH_BACKEND_URL (the per-project Vercel env var). Proxy, not redirect, so the osw_session cookie stays first-party (same-origin). The build fails loudly if LANGGRAPH_BACKEND_URL is missing on Vercel; the rule is omitted for plain local/off-Vercel builds (which use the E2E_HARNESS mock proxy). - `vercel.json`: `buildCommand` back to `bun run build`; drop the `.output/public` outputDirectory so Vercel serves Nitro's `.vercel/output`. Validated with `LANGGRAPH_BACKEND_URL=... NITRO_PRESET=vercel bun run build`: the generated `.vercel/output/config.json` contains the `/dashboard/api/(.*)` -> backend rewrite ahead of `handle: filesystem` and the SPA catch-all, `_shell.html` and the 699 hashed assets are emitted, and typecheck passes. Supersedes the broken approach in #75.
