## Summary
Two related improvements to Stack Auth's AI setup story, both driven by
`packages/stack-shared/src/ai/prompts.ts`:
### 1. Clearer env-var guidance in the cloud-project flow (existing
commit)
The previous wording suggested `STACK_PROJECT_ID` should be prefixed via
a generic _"if available, prefix with your framework's convention"_
comment, and the backend section additionally listed
`NEXT_PUBLIC_STACK_PUBLISHABLE_CLIENT_KEY` — which the SDK does not
actually read in the cloud-project setup. Agents would dutifully
fabricate that third variable.
This is now spelled out:
- The exact prefix per framework (Next.js →
`NEXT_PUBLIC_STACK_PROJECT_ID`, Vite → `VITE_STACK_PROJECT_ID`, etc.) is
given inline.
- A note clarifies that on the client, **only** the project ID is read —
there is no separate publishable / client key.
- A note clarifies that the backend setup reads exactly two variables
(`STACK_PROJECT_ID` + `STACK_SECRET_SERVER_KEY`); a third slot in
`.env.local` is wrong.
### 2. First-class TanStack Start support (new commit)
Until now `mainType: "tanstack-start"` was silently routed through
`@stackframe/react` and inherited the React-only setup steps. Agents had
to guess at the TanStack-specific bits (where to mount `StackProvider`,
what to do with `routeTree.gen.ts`, how `useUser()` behaves under SSR,
where the handler route lives).
`prompts.ts` now:
- Recognizes TanStack Start as its own `mainType` and routes the install
to `@stackframe/tanstack-start`.
- Lists TanStack Start alongside Next.js / React in the
supported-frameworks list and the package table.
- Adds three TanStack-specific steps that don't apply to vanilla React:
1. Mount `StackProvider` / `StackTheme` inside the root route's
`component` (the inner React tree), keeping `shellComponent` as the
document shell.
2. Wrap `<Outlet />` in `Suspense` inside `RootComponent`.
3. Register the Stack handler splat at `src/routes/handler/\$.tsx` with
`ssr: false`.
- Surfaces the two notes that aren't obvious from the React docs:
`routeTree.gen.ts` is generated and shouldn't be hand-edited, and
`useUser()` resolves the SSR user from TanStack Start's request cookies
for free as long as `tokenStore: \"cookie\"` is set.
The auto-generated outputs
(`docs-mintlify/guides/getting-started/setup.mdx`,
`docs-mintlify/snippets/home-prompt-island.jsx`) are regenerated from
the prompt.
### 3. tanstack-start-demo SSR-vs-client examples
Two paired routes (`/ssr` and `/client`) render the same `AuthDemoCard`
so the SSR-vs-\`ssr: false\` tradeoff is observable side-by-side. The
new \`AuthDemoCard\` shows the resolved Stack Auth user (or sign-in/up
buttons) plus the snippet that produced it. The
\`ClientMountedUserButton\` workaround in the header is dropped now that
SSR cookie reading just works, and the empty \`Suspense
fallback={null}\` in \`__root.tsx\` is replaced with a
\`RouteLoadingState\` skeleton.
## Test plan
- [ ] \`pnpm typecheck\` and \`pnpm lint\` both pass on the touched
packages (\`stack-shared\`, \`tanstack-start-demo\`).
- [ ] \`docs-mintlify/guides/getting-started/setup.mdx\` and
\`docs-mintlify/snippets/home-prompt-island.jsx\` are byte-identical to
a fresh \`scripts/generate-setup-prompt-docs.ts\` run.
- [ ] In \`tanstack-start-demo\`, \`/ssr\` renders the user card during
the server response (no flash from signed-out → signed-in), and
\`/client\` renders the empty card on first paint, then resolves to the
user after hydration.
- [ ] \`/handler/sign-in\`, \`/handler/sign-up\`, OAuth callbacks, and
password reset all render correctly through the new splat route.
- [ ] Following the new TanStack Start prompt steps from scratch in an
empty \`npm create @tanstack/start@latest\` project produces a working
sign-in flow without any extra changes.

With the new bulldozer rework we dont support default products anymore.
Users are encouraged to currently manually handle granting products to
their end users.
We block api requests and new product creations that attempt to set no
price, and we remove any options to set include-by-default. We also
migrate users' existing product snapshots in `Subscriptions`,
`OneTimePurchases`, and `ProductVersions` to have no price set if it's
an include-by-default product. This will make it so that next time a
user goes onto their products page, they will be informed that the
pricing is invalid and it is no longer delivered by default.
Note, however, that these products will still be providing items and the
like to the users who have them.
<!-- This is an auto-generated comment: release notes by coderabbit.ai
-->
## Summary by CodeRabbit
* **Bug Fixes**
* Migrated legacy product snapshots so missing included-items no longer
break readers.
* Removed deprecated "include-by-default" pricing sentinel; pricing now
requires explicit price entries and write validation rejects the old
sentinel.
* **Chores**
* Simplified dashboard pricing flows: create/edit/save now use explicit
prices and surface an alert when a formerly implicit free plan needs an
explicit $0 price.
* Config overrides and stored data are auto-normalized to explicit price
objects.
* **Tests**
* Updated and added tests covering migration, validation, and switching
behavior for explicit prices.

## Summary
- Adds the generated `@stackframe/tanstack-start` workspace package
registration.
- Adds TanStack Start platform macros/dependencies to the SDK template
and generator.
- Adds TanStack Start cookie/token-store support plus the handler SSR
guard needed by Start.
## Scope
This intentionally excludes Dashboard V2 routes, hooks, components, app
shell logic, and dashboard API type additions. Those stay in the
existing dashboard PR/branch.
## Validation
- `pnpm install --lockfile-only --ignore-scripts`
- `pnpm install --ignore-scripts`
- `pnpm -C packages/template lint
src/components-page/stack-handler-client.tsx src/lib/cookie.ts
src/lib/stack-app/apps/implementations/client-app-impl.ts`
Package typecheck was attempted with `pnpm -C packages/template
typecheck`, but the clean worktree lacks generated package declaration
outputs for workspace dependencies such as `@stackframe/stack-shared`
and `@stackframe/stack-ui`. Per repo instructions, package
builds/codegen are not run by agents.

cookie/token-store behavior across SSR and client.
* **Documentation**
* New Integrations guide and expanded getting-started/setup docs with
TanStack Start examples and env/key guidance.
* **Chores**
* Template, build, tooling, and demo config updates to support the new
platform.

- Extended `CliAuthAttempt` with `anonRefreshToken` and a migration.
- CLI `POST /auth/cli` accepts optional `anon_refresh_token` (must be an
anonymous user's refresh token for the current project).
- `POST /auth/cli/complete` supports `mode` `check` (anonymous vs none),
`claim-anon-session` (issue tokens for the linked anonymous session),
and `complete` (bind the browser session's refresh token to the
attempt). Completing clears `anonRefreshToken` on the row. We do **not**
merge anonymous account data into the signed-in user (that behavior was
removed as a security risk; the anonymous user remains unchanged).
- Template CLI confirmation page, stack-cli optional
`STACK_CLI_ANON_REFRESH_TOKEN`, SDK/spec updates, and e2e coverage.

## Summary by CodeRabbit
* **New Features**
* CLI login supports attaching anonymous sessions and a multi-mode
confirm/claim/check flow; CLI tools now surface login codes and remove
anon token after use.
* Added interactive CLI auth demo page and a CLI simulator script.
* Client libraries: prompt flow accepts an optional anon token and a
promptLink(url, loginCode) callback.
* **Tests**
* Expanded end-to-end coverage for anonymous CLI sessions,
claim/complete/poll flows, upgrades, and error cases.
* **Documentation**
* Updated prompt CLI docs/spec to describe new options and callback
signature.

The gate delayed flushes until an access token resolved, but sendBatch
already resolves the session itself via _getSession() at send time, so
_lastKnownAccessToken was a redundant readiness check that caused
head-of-session events to be silently dropped on slow auth init and
suppressed uploads entirely when token fetch failed.

## Summary by CodeRabbit
* **Refactor**
* Simplified analytics, session-replay, and event-tracking to stop
periodic background access-token refreshes; flushing now occurs based on
buffered data and lifecycle triggers.
* **Bug Fixes**
* Anonymous-user fallback tightened: anonymous identity is only applied
when explicitly requested as "anonymous-if-exists," preventing
unintended anonymous attribution.
* **Tests**
* Updated timing helper and removed token callback from test setups to
align with the new flush behavior.

Other minor redirect URL changes:
- app.urls.* is now deprecated
- redirectToSignOut now sets and preserves after_auth_return_to
- OAuth sign-in after_auth_return_to now carries callback-return context
<!-- CURSOR_SUMMARY -->
---
> [!NOTE]
> **High Risk**
> High risk because it changes OAuth authorization/token issuance,
redirect URL validation, and introduces a new cross-domain handoff
endpoint plus a DB migration linking authorization codes to refresh
tokens, which can affect login/session security and reliability.
>
> **Overview**
> Adds **hosted URL targets** for SDK `urls` resolution (new `{ type:
"hosted" }`/`{ type: "handler-component" }`/`{ type: "custom" }`
options), including env-driven hosted handler domain/template support
and fallback routing for unknown `/handler/*` paths.
>
> Implements a **cross-domain OAuth PKCE handoff**: a new
`/auth/oauth/cross-domain/authorize` endpoint issues one-time
authorization-code redirects bound to the caller’s session refresh
token; authorization codes now persist `grantedRefreshTokenId` and token
issuance reuses/validates ownership of that refresh token. Redirect
planning for `redirectTo*` (and OAuth callback handling) is refactored
into `redirect-page-urls.ts` to preserve `after_auth_return_to` and
cross-domain handoff params.
>
> Tightens redirect safety (e.g., `after_callback_redirect_url` is
validated/whitelisted), centralizes SDK env var reads via `envVars` with
lint enforcement, hardens `EventTracker` startup for partial DOM test
environments, and adds unit/E2E coverage plus a demo page for manual
cross-domain verification.

- Introduced a fallback mechanism for the private sign-up risk engine,
allowing for zero-score assessments when the primary engine is
unavailable.
- Updated Next.js configuration to support dynamic resolution of the
private risk engine, including aliasing for both Turbopack and Webpack.
- Added a new fallback implementation in
`private-sign-up-risk-engine-fallback.ts` to ensure consistent behavior
during builds.
- Adjusted `risk-scores.tsx` to utilize the new compiled engine,
improving error handling and logging for risk assessment failures.
This update improves the robustness of the sign-up risk scoring system
and enhances the development experience by streamlining engine
resolution.

> [!NOTE]
> **High Risk**
> Touches authentication and OAuth token/authorize flows and changes how
client requests are validated, so regressions could cause widespread
login/client-access failures. Also includes a data migration that alters
effective security posture for existing projects.
>
> **Overview**
> Adds a **project-level toggle**
(`project.requirePublishableClientKey`) to control whether client
requests/OAuth flows must include a publishable client key, including a
DB migration that backfills existing projects to require it.
>
> Backend auth now treats the publishable client key as *optional when
allowed*, introducing a public sentinel (`__stack_public_client__`) and
returning a new specific error
(`PUBLISHABLE_CLIENT_KEY_REQUIRED_FOR_PROJECT`) across smart request
auth + OAuth `authorize`/`callback`/`token` endpoints.
>
> Dashboard and SDKs update key generation/display and request
construction to handle missing publishable keys, expose an advanced
toggle on the Project Keys page, and extend internal config overrides to
support a new `project` level; E2E/tests and schema fuzzing are expanded
accordingly, and CI adds a forward-compat migration check job when
back-compat fails.
