 ## Deployment
 
-The frontend is hosted on Vercel at `https://debate.pi-stack.org`. Merging to `main` starts a Vercel production deployment, so a merge ships the frontend. Supabase migrations and Edge Functions are not deployed to production by that merge; production deploys are separate authorized operations. Staging syncs itself from `main` within about 5 minutes through a VPS timer; [docs/staging.md](docs/staging.md) is the one place for staging access, seed data, and the sync. `npm run backend:status` (read-only) lists what the linked project is missing; run it before any backend deploy.

 Vercel previews are opt-in. A push to `main` deploys both Vercel projects (production, and the staging project's site, which also tracks `main`). A push to any other branch does not create a deployment and does not count toward the daily cap. Request a hosted preview only when there is a real UI change to check.

A push to `main` deploys both projects: `debate-navigator` to `https://debate.pi-stack.org`, and `debatelab-staging` to `https://debatelab-staging.vercel.app`. Any other branch waits for an explicit preview (see [Opt-in previews](#opt-in-previews)). For a staging-pinned preview on the tailnet, use `npm run dev:preview` (see [development.md](development.md#preview-on-the-tailnet)). The production canary runs after each successful Vercel `Production` deployment of `debate-navigator`.

 Choose rollback before changing production:
 
-- Frontend: promote the previous known-good Vercel production deployment (about 10 seconds), or revert the commit on `main` and let Vercel redeploy (one to two minutes). The Vercel project is `debate-navigator`. `vercel inspect debate.pi-stack.org` shows the live deployment, `vercel ls debate-navigator --environment production --status READY` lists the earlier ones, and `vercel rollback <previous-deployment-url> --yes` switches back. On Adam's VPS, `~/ops/rollback/rollback vercel debate-navigator` does all three. After a rollback, Vercel stops putting new `main` deployments live until one is promoted with `vercel promote <deployment-url>`, so promote the fixed deployment once it is ready. A frontend rollback does not touch Supabase: if the bad change came with a migration or function deploy, the old frontend must still work with the new backend.

 - Configuration: record the prior value without exposing secrets.
