+# Phase 07 Plan 02: Setup Wizard Completion and Routing Summary
+
+ReviewStep with grouped read-only summary, wizard completion logic (category + template item creation with duplicate handling), skip flow, /setup route registration, and first-run redirect from dashboard.
+
+## Commits
+
+| Task | Commit | Description |
+|------|--------|-------------|
+| 1 | 396d342 | ReviewStep component and wizard completion/skip logic |
+| 2 | 6b75f14 | Register /setup route and add first-run redirect |
+
+## What Was Built
+
+1. **ReviewStep** - Read-only summary component showing income, grouped checked items by category type, total expenses, and remaining balance. Uses Intl.NumberFormat for currency formatting. Remaining is colored green (text-on-budget) when positive, red (text-destructive) when negative.
+
+2. **Wizard Completion Logic** - handleComplete creates one category per needed type (handles 23505 duplicate constraint), creates template items for all checked presets, marks profiles.setup_completed=true, clears localStorage wizard state, invalidates React Query cache, shows toast, and redirects to dashboard.
+
+3. **Skip Flow** - handleSkipSetup clears localStorage, marks setup_completed=true without creating any data, and redirects to dashboard.
+
+4. **Double-submit Prevention** - `completing` state disables all buttons during API calls (T-07-04 mitigation).
+
+5. **/setup Route** - Registered in App.tsx as a protected standalone page (inside ProtectedRoute, outside AppLayout). Unauthenticated users are redirected to /login (T-07-06 mitigation).
+
+6. **First-run Redirect** - DashboardPage uses useFirstRunState to detect users with no categories/template items and redirects them to /setup. Shows DashboardSkeleton during loading.
+
+7. **Redirect Loop Prevention** - Query invalidation for ["categories"] and ["template-items"] after completion ensures useFirstRunState reads fresh data showing isFirstRun=false (T-07-07 mitigation).
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 1 - Bug] Fixed React hooks rule violation in DashboardPage**
+- **Found during:** Task 2
+- **Issue:** Plan instructed placing early returns before useMonthParam/useBudgets calls, which violates React rules of hooks (hooks cannot be called conditionally)
+- **Fix:** Moved all hook calls (useMonthParam, useBudgets, useMemo) above the early return statements
+- **Files modified:** src/pages/DashboardPage.tsx
+- **Commit:** 6b75f14
+
+## Known Stubs
+
+None - all stubs from Plan 01 have been resolved.
+
+## Self-Check: PASSED
