Pay retains its Next.js publisher and adds a TanStack Start/Void candidate. It consumes the shared bridge, page adapter, action transport and internal API resolver. The conversion adds no database migration, payment job or schedule. A source build is not payment-provider acceptance or production cutover. ## Use root-only staging The staging candidate admits only the exact Pay staging host on the separate staging zone, behind Cloudflare Access, never a `*.tuturuuu.com` name. It rejects `pay.tuturuuu.com`, apex mounts and unknown hosts before app code. The cutover-prep PR must add `pay.tuturuuu.com` together with its separately reviewed production profile; apex hosting remains held by the shared auth guard. Staging cookies are host-only. Pay staging sends only `__Host-` session cookies with no `Domain` attribute, and the Worker exit applies the shared staging cookie policy: a staging response that carries a `Set-Cookie` with `Domain` returns 500 instead. Production keeps the `.tuturuuu.com` shared session scope. A test fails if any staging root host is a `*.tuturuuu.com` name. `cloudflare/staging-profile.json` owns the staging values used by Void, artifact qualification and runtime checks. It pins the exact Pay and Web/API staging origins on the staging zone, the repository's staging Supabase project, and `POLAR_SANDBOX=true`. Supply only sandbox Polar credentials. The artifact helper rejects a missing or false sandbox flag. This staging-data artifact cannot be admitted as a production profile. Every response sends noindex, X-Frame-Options DENY, nosniff and the strict-origin referrer policy. CSP includes `frame-ancestors 'none'`. The exact shared WebGL asset path is the framing exception: its upstream sandbox CSP passes through unchanged and X-Frame-Options is removed. Exact-path, descendant and neighbouring framing controls run against the staging root; the production host is explicitly rejected. Personalized SSR and API responses use private/no-store caching and vary on Cookie, Authorization and Accept-Language. Only successful GET/HEAD compiled-asset responses keep their static caching. `global_fetch_strictly_public` is required; hosted acceptance must show same-zone self-fetches reach the Worker rather than retained Vercel. ## Preserve route and payment authority The source inventory has six pages, one server-action module and 26 local API handlers. Local billing, payment, webhook and existing job routes retain their ownership; unmatched APIs forward to Web. Conversion does not authorize invoking migration/job endpoints or changing provider webhook routing. Exact GET/HEAD `/api/build-info` are public deployment identity reads. Their ambient credentials are removed, and the shared guard remains in place. Other methods and lookalike paths retain session checks. Polar webhook POSTs and the existing cron GETs retain their handler signature/secret checks and shared edge protection; no scheduler is enabled by the candidate. ## Qualify the emitted artifact Run the exact-head unit, Next/Cloudflare types, lint, real `vp build`, registry and route-tree checks, binding harness, emitted config and Wrangler dry-run on a build host through `ttr resources run`. Seal the output with `scripts/ci/pay-native-artifact.py`, transfer it through a relay host, and run both the transferred and roundtrip-restored artifact on a browser host under browser admission. Run `bun check:changed` before publication. The relay host runs no builds or containers. The native workflow calls the shared qualification template. The generated raw Host suite consumes declared root/login/dashboard outcomes from `start-bridge.routes.json`. The app-owned runtime checks public build identity, negative API controls, response security, staging auth-return origin, invalid webhook rejection, missing cron authority, root-only host rejection and bounded CDP-fenced Chromium navigation. All outbound database/provider requests are blocked in these fixtures. This is not hosted shared-session, checkout or payment-provider acceptance. ## Require provider sandbox acceptance Before staging sign-off, record the sandbox account, exact Worker source/version, profile/bindings and test identities through the release owner. Exercise: * EN/VI signed-in workspace billing and permission denial across workspaces. * Checkout completion and cancellation, credit packs and subscription changes. * Valid signed webhook delivery and invalid signature rejection. * Replay the same valid delivery with the same `webhook-id` and verify deduplication: no duplicate credits, invoices, subscription changes or other payment side effects. Webhook-id deduplication remains a sandbox acceptance gate; this migration adds no dedupe code. * Seat changes, invoice delivery, billing details and the customer portal. * Auth verification, refresh, logout and same-zone self-fetch on hosted staging. Use disposable sandbox records and the original operation identity for any uncertain write. Stop on an unknown outcome; do not replay blindly. No live payments, production Polar credentials or live webhook reconfiguration are admitted by these checks. After independent review and hosted acceptance, the release owner's explicit cutover-prep PR admits the production artifact/bindings and legacy-publisher hold. The direct root-mode cutover needs a captured immutable Vercel deployment, DNS payload and one-step rollback, followed by smoke and a 30–60 minute 5xx/auth/p95 watch. Production stays held until those gates pass. This documentation is built and hosted on [Mintlify](https://mintlify.com), a developer documentation platform.
