+# 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
+3. **Immediate Session Expiration** - Users were getting logged out immediately after logging in
+4. **External Service 401 Errors** - 401 errors from external services (CMS, database) were logging users out
+
+## 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
+
+### Immediate Logout Cause
+- The authorization middleware was making its own API call, bypassing the session cache
+- The auth refresh plugin's 2-minute periodic validation was conflicting with the 3-minute session cache
+- Multiple concurrent session checks were causing race conditions
+
+### External Service 401 Cause
+- The auth error handler was treating ANY 401 error as a session expiration
+- When the CMS (`cms.portnimara.dev`) returned 401, it triggered a logout
+- The handler didn't distinguish between auth API errors and external service errors
+
+## 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
+- Safe auth state access to prevent initialization errors
+
+### 5. Fixed Authorization Middleware
+**File**: `middleware/authorization.ts`
+
+Updated to use cached auth state instead of making API calls:
+```javascript
+// Get auth state from authentication middleware (already cached)
+const nuxtApp = useNuxtApp();
+const authState = nuxtApp.payload?.data?.authState;
+```
+
+This prevents:
+- Duplicate API calls
+- Race conditions between middlewares
+- Session cache conflicts
+
+### 6. Adjusted Auth Refresh Plugin
+**File**: `plugins/01.auth-refresh.client.ts`
+
+- Changed periodic validation from 2 to 5 minutes to avoid conflicts with 3-minute cache
+- Added failure counting - only logs out after 3 consecutive failures
+- Increased random offset to prevent thundering herd
+
+### 7. Fixed Auth Error Handler
+**File**: `plugins/02.auth-error-handler.client.ts`
+
+Updated to only handle 401/403 errors from application endpoints:
+```javascript
+// Only handle authentication errors from our own API endpoints
+const isAuthEndpoint = response.url && (
+  response.url.includes('/api/auth/') ||
+  response.url.includes('/api/') && !response.url.includes('cms.portnimara.dev') && !response.url.includes('database.portnimara.com')
+)
+
+// Handle authentication errors (401, 403) only from our API
+if ((response.status === 401 || response.status === 403) && isAuthEndpoint) {
+  // Clear auth and redirect
+} else if (response.status === 401 && !isAuthEndpoint) {
+  console.log('[AUTH_ERROR_HANDLER] Ignoring 401 from external service:', response.url)
+  // Don't clear auth for external service 401s
+}
+```
+
+This prevents external service authentication errors from logging users out.
+
+## 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
+5. **No immediate logout** - Session checks are properly coordinated and cached
+6. **Stable session management** - No conflicts between different auth checking mechanisms
+7. **External service errors ignored** - 401 errors from CMS or database won't log users out
+
+## 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 authorization middleware uses cached auth state instead of making API calls
+- The dashboard layout shows the current user and their role with safe access patterns
+- 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
+- Auth refresh plugin runs validation every 5 minutes to avoid cache conflicts
+- Multiple failure tolerance prevents transient issues from logging users out
+- Auth error handler differentiates between app and external service errors
+
+## Timing Configuration Summary
+
+- **Session Cache**: 3 minutes (with 0-10 second jitter)
+- **Auth Refresh Validation**: Every 5 minutes (with 0-10 second offset)
+- **Token Refresh**: 5 minutes before token expiry
+- **Failure Tolerance**: 3 consecutive failures before logout
+
+This configuration ensures no timing conflicts between different auth mechanisms.
+
+## External Service Integration
+
+The auth error handler now properly handles errors from external services:
+- **CMS errors** (cms.portnimara.dev) - 401 errors are logged but don't trigger logout
+- **Database errors** (database.portnimara.com) - 401 errors are logged but don't trigger logout
+- **App API errors** (/api/*) - 401/403 errors still trigger logout as expected
+
+This allows the app to gracefully handle authentication failures with integrated services without disrupting the user's main session.

+# Authentication Session Timeout Fix - Deployment Guide
+
+## Overview
+
+This document provides step-by-step instructions for deploying the authentication session timeout fixes that resolve the 2-minute logout issue.
+
+## Problem Summary
+
+Users were experiencing unexpected logouts after exactly 2 minutes when navigating between pages. This was caused by:
+
+1. **Timing Race Condition**: Authentication middleware cache expiry (2 minutes) and auth refresh plugin periodic validation (2 minutes) occurring simultaneously
+2. **No Request Deduplication**: Multiple concurrent session checks causing conflicts
+3. **Insufficient Error Handling**: Network errors triggering immediate logouts
+4. **No Grace Periods**: Transient issues causing permanent session loss
+
+## Solution Overview
+
+### Core Changes
+
+1. **Session Manager Utility** (`server/utils/session-manager.ts`)
+   - Centralized session management with request deduplication
+   - Promise caching for in-flight requests
+   - Network error grace periods
+   - Comprehensive logging and statistics
+
+2. **Authentication Middleware** (`middleware/authentication.ts`)
+   - Changed cache expiry from 2 to 3 minutes with jitter
+   - Integrated SessionManager for deduplication
+   - Enhanced error handling and user feedback
+
+3. **Auth Refresh Plugin** (`plugins/01.auth-refresh.client.ts`)
+   - Added random offset to prevent simultaneous validation
+   - Improved concurrent validation prevention
+   - Better error handling for network issues
+
+4. **Session API** (`server/api/auth/session.ts`)
+   - Enhanced logging with request IDs
+   - Detailed error categorization
+   - Performance timing measurements
+
+5. **Keycloak Client** (`server/utils/keycloak-client.ts`)
+   - Better error type distinction
+   - Increased retry attempts for token refresh
+   - Improved timeout handling
+
+6. **Refresh API** (`server/api/auth/refresh.ts`)
+   - Enhanced error handling with request IDs
+   - Grace period support for transient failures
+   - Selective session clearing based on error type
+

+
+## Monitoring and Alerts
+
+### Key Metrics to Monitor
+
+1. **Authentication Errors**
+   ```bash
+   # Monitor auth failure rate
+   grep -c "AUTH_ERROR" /var/log/application.log
+   ```
+
+2. **Session Manager Performance**
+   ```bash
+   # Check session check durations
+   grep "Session check completed" /var/log/application.log
+   ```
+
+3. **Cache Hit Rate**
+   ```bash
+   # Monitor cache effectiveness
+   grep "Using cached session" /var/log/application.log | wc -l
+   ```
+
+### Alert Thresholds
+
+- **Auth Error Rate**: > 5% of total auth checks
+- **Session Check Duration**: > 2 seconds average
+- **Cache Miss Rate**: > 80% (indicates caching issues)
+
+## Rollback Procedures
+
+### Immediate Rollback (if critical issues)
+
+1. **Stop Application**
+   ```bash
+   systemctl stop your-application
+   ```

+3. **Restart Application**
+   ```bash
+   systemctl start your-application
+   ```
+
+4. **Verify Rollback**
+   - Test login functionality
+   - Check error logs
+   - Verify user sessions work
+
+### Partial Rollback (if specific component issues)
+
+1. **Identify Problem Component**
+   - Check which specific file is causing issues
+   - Review recent error logs
+
+2. **Rollback Specific Files**
+   ```bash
+   git checkout HEAD~1 -- middleware/authentication.ts
+   # or
