+# 404 and Session Expiration Fixes
+
+## Issues Addressed
+
+1. **404 Error on Expenses Page** - The expenses page was returning a 404 error
+2. **Session Expiration After 404** - Users were getting logged out after encountering the 404 error
+
+## Root Cause Analysis
+
+### 404 Error Cause
+- The expenses page was missing the authorization middleware configuration
+- The dashboard layout referenced in the page metadata didn't exist
+- Nuxt wasn't properly configured to use layouts
+
+### Session Expiration Cause
+- The authentication middleware was incorrectly clearing the session cache on ALL errors (including 404s)
+- This caused a valid session to be invalidated when encountering any page error
+
+## Fixes Implemented
+
+### 1. Fixed Expenses Page Metadata
+**File**: `pages/dashboard/expenses.vue`
+
+Added proper middleware configuration:
+```javascript
+definePageMeta({
+  middleware: ['authentication', 'authorization'],
+  layout: 'dashboard',
+  roles: ['sales', 'admin']
+});
+```
+
+This ensures:
+- Authentication is checked first
+- Authorization checks for sales/admin roles
+- Proper layout is applied
+
+### 2. Fixed Authentication Middleware
+**File**: `middleware/authentication.ts`
+
+Updated error handling to only clear cache on actual auth errors:
+```javascript
+onResponseError({ response }) {
+  // Clear cache only on actual auth errors, not 404s or other errors
+  if (response.status === 401) {
+    console.log('[MIDDLEWARE] Unauthorized error detected, clearing cache')
+    sessionManager.clearCache();
+    delete nuxtApp.payload.data?.authState;
+  } else if (response.status === 403) {
+    console.log('[MIDDLEWARE] Forbidden error detected, partial cache clear')
+    // Don't clear cache on 403 as user is authenticated but lacks permissions
+  }
+  // Ignore 404s and other errors - they're not authentication issues
+}
+```
+
+### 3. Enabled Layout Support
+**File**: `app.vue`
+
+Updated to support layouts:
+```vue
+<template>
+  <NuxtPwaManifest />
+  <NuxtLayout>
+    <NuxtPage />
+  </NuxtLayout>
+  <GlobalToast />
+</template>
+```
+
+### 4. Created Dashboard Layout
+**File**: `layouts/dashboard.vue`
+
+Created a full dashboard layout with:
+- Navigation drawer with role-based menu items
+- App bar showing user info and role badges
+- Proper logout functionality
+- Responsive design with rail mode
+
+## Expected Results
+
+1. **Expenses page should now load properly** for users with sales or admin roles
+2. **404 errors won't cause session expiration** - only actual authentication failures (401) will clear the session
+3. **Better error handling** - 403 errors (insufficient permissions) will redirect to dashboard with a message instead of logging out
+4. **Consistent layout** across all dashboard pages
+
+## Testing Steps
+
+1. Log in with a user that has sales or admin role
+2. Navigate to `/dashboard/expenses`
+3. Verify the page loads without 404
+4. If you don't have the required role, you should be redirected to dashboard with an error message (not logged out)
+5. Try navigating to a non-existent page - you should get a 404 but remain logged in
+
+## Additional Improvements
+
+- The authorization middleware now stores error messages that are displayed via toast
+- The dashboard layout shows the current user and their role
+- Navigation menu dynamically shows/hides items based on user roles
+- Session validation continues to work with the 3-minute cache + jitter to prevent race conditions
