Re-lands #12121 (reverted in #12189) with the sign-in loop fixed.

The loop: the edge gate and the private session key only looked for stack-refresh-<project>. Current Stack SDKs store the refresh token as hexclave-refresh-<project>--<suffix> (with a __Host- prefix on secure origins) and treat the old name as legacy, so every signed-in visitor was sent to sign-in and back.

The fix: one resolver in app/lib/stack-session-cookies.ts mirrors the SDK's refresh cookie name patterns and is used by both the middleware and the session key. Unit tests cover every name variant.

Proof this time used a real browser, not hand-built cookies: headless Chromium signed in through Stack's own password form against a local production build with the dev Stack project. The browser received hexclave-refresh-<project>--default, then loaded /dashboard/coderouter, /dashboard/cloud, /dashboard/coderouter and /dashboard, staying on each page with the account email rendered and zero visits to /handler/sign-in.

Everything else is the reviewed content of the original PR: private session cache, static shell with Suspense sections, edge redirect for cookieless visitors, prefetch opt-outs removed, docs namespace dropped from the shared client catalog.

Summary by cubic

Re-lands instant dashboard navigation with a fix for the sign-in loop that sent every signed-in visitor back to sign-in.

Bug Fixes

  • Aligns session cookie detection with current Stack SDK naming, which uses hexclave-refresh-* and legacy stack-refresh-* patterns.
  • Adds a shared resolver in web/app/lib/stack-session-cookies.ts used by both middleware and the session key.
  • Covers all cookie name variants with unit tests and verifies the flow in a headless browser against a production build.

Dashboard Navigation

  • Restores the private session cache and static dashboard shell with Suspense-bounded private sections.
  • Redirects cookieless visitors at the edge before rendering any dashboard shell.
  • Removes prefetch opt-outs from dashboard links and drops the docs namespace from the shared client catalog.

Written for commit 316166e. Summary will update on new commits.

Summary by CodeRabbit

  • New Features

    • Dashboard pages now load static navigation and headers immediately while private content streams in with loading placeholders.
    • Signed-out dashboard visitors are redirected to sign-in with their original destination preserved.
    • Dashboard sections provide contextual recovery prompts when authentication services are temporarily unavailable.
    • Documentation pages now load their localized messages correctly.
  • Bug Fixes

    • Improved dashboard session and sign-out handling across cloud, team, Coderouter, and TestFlight pages.
    • Dashboard authentication now recognizes current and legacy session cookie formats.

…on gate

The edge gate and the private session key looked only for
stack-refresh-<project>. Current Stack SDKs store the refresh token under
hexclave-refresh-<project>--<suffix>, optionally with a __Host- prefix, and
treat the old name as legacy, so signed-in users looped between sign-in and
the dashboard. One shared resolver mirrors the SDK's cookie name patterns
for both the middleware and the session key.

📝 Walkthrough

Walkthrough

The PR centralizes dashboard session handling, gates dashboard routes with Stack refresh cookies, streams private sections behind static shells, and adds recovery states. It also scopes client message catalogs so the docs namespace loads in its route layout.

Changes

Dashboard session and streaming

Layer / File(s) Summary
Session and cookie foundations
web/app/lib/dashboard-session.ts, web/app/lib/stack-session-cookies.ts, web/tests/stack-session-cookies.test.ts
Adds refresh-cookie matching, cached session resolution, typed session errors, and sanitized session users.
Dashboard authentication orchestration
web/app/lib/dashboard-auth.ts, web/app/[locale]/dashboard/components/*, web/app/[locale]/dashboard/dashboard-account-menu.tsx
Adds shared section loading, optional account sessions, recovery UI, skeletons, and Stack app sign-out.
Static dashboard shell and account slot
web/app/[locale]/dashboard/layout.tsx, web/app/[locale]/dashboard/dashboard-shell.tsx, web/app/[locale]/dashboard/page.tsx, web/app/[locale]/dashboard/coderouter/page.tsx
Moves session-dependent content behind Suspense while keeping dashboard shells and navigation static.
Streamed dashboard sections
web/app/[locale]/dashboard/cloud/page.tsx, web/app/[locale]/dashboard/team/page.tsx, web/app/[locale]/dashboard/testflight/page.tsx
Loads private sections through loadDashboardSection and renders skeleton or recovery states.
Dashboard edge session gating
web/proxy.ts, web/e2e/instant/dashboard-navigation.instant.ts, web/tests/dashboard-middleware-session.test.ts
Redirects requests without matching Stack refresh cookies and preserves dashboard return paths.
Dashboard streaming validation
web/tests/dashboard-*, web/tests/helpers/*
Updates dashboard tests for streamed rendering, session cookies, account slots, redirects, and settled HTML streams.

Client message catalogs

Layer / File(s) Summary
Shared and subtree message catalogs
web/i18n/client-messages.ts, web/app/[locale]/layout.tsx, web/tests/client-messages.test.ts
Centralizes message pruning and removes the docs namespace from the shared catalog.
Docs message provider
web/app/[locale]/(landing)/docs/layout.tsx
Loads pruned messages and provides the docs namespace through NextIntlClientProvider.

Supporting maintenance

Layer / File(s) Summary
Ignore rule and type contract
web/.gitignore, web/services/billing/pro.ts
Ignores Playwright output and narrows the TestFlight eligibility user parameter to its required identity field.

Priority: ➖ Normal

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🔵 Low · up to 31616

Dashboard behavior remains at risk of regressions escaping tests because navigation errors, return targets, and streamed render failures are not fully asserted. Address these focused test gaps before relying on this suite for future dashboard authentication changes.

The refresh-cookie name depends on an unpinned environment variable. Both requests build stack-refresh-${process.env.NEXT_PUBLIC_STACK_PROJECT_ID ?? "none"}. hasStackSessionCookie in web/proxy.ts returns true without cookie matching when that variable is unset, so both assertions pass even if refresh-cookie matching breaks. Set the variable for the suite with beforeAll/afterAll and use TEST_STACK_PROJECT_ID from ./helpers/dashboard-session-mock.

Remove the mutable module-level currentUser.

Each test assigns currentUser before passing it as the explicit user prop. The signed-out test passes null, so its render is not order-dependent. Replace these assignments with local values such as user={sessionUser()} or user={null}. This removes shared test state and satisfies the test-isolation contract.

Make unstable_rethrow preserve notFound errors. createNextNavigationMock.notFound throws Error("notFound"), but the helper only rethrows errors beginning with "redirect:". In dashboard-auth.ts, caught errors that pass through this mock can become { kind: "unavailable" } or null instead of propagating as navigation control flow. Re-throw the "notFound" marker from the shared helper.

Pass a render-error handler from the streaming-error test. DashboardSessionGuard runs inside Suspense, and the rejected-session test’s mocked redirect throws after the shell. React 19.2.3 calls onError and can still resolve allReady, so the current one-argument call can pass after only checking redirectedTo. Add the optional callback and use it in this test to assert the expected redirect error and reject unexpected errors. Adding the callback alone does not affect any current caller because all callers pass only node.

…ookies (manaflow-ai#12191)

* Reapply "web: make dashboard navigation instant with a private session cache (manaflow-ai#12121)" (manaflow-ai#12189)

This reverts commit b9eb587.

* web: recognize every Stack refresh cookie name in the dashboard session gate

The edge gate and the private session key looked only for
stack-refresh-<project>. Current Stack SDKs store the refresh token under
hexclave-refresh-<project>--<suffix>, optionally with a __Host- prefix, and
treat the old name as legacy, so signed-in users looped between sign-in and
the dashboard. One shared resolver mirrors the SDK's cookie name patterns
for both the middleware and the session key.
