+# Audit Logging Implementation
+
+This document describes the audit logging system implemented for the panel application. The system provides comprehensive tracking of user actions and system events for security, compliance, and monitoring purposes.
+
+## Features
+
+- **Comprehensive Action Tracking**: Logs all CRUD operations on projects, tasks, contracts, notes, and user management
+- **Authentication Events**: Tracks login attempts, successes, and failures
+- **Detailed Context**: Captures IP addresses, user agents, and request details
+- **Flexible Filtering**: Query logs by user, action, resource type, date range, and more
+- **Statistics Dashboard**: Provides insights into system usage patterns
+- **Role-based Access**: Only admins and project managers can view audit logs
+- **Performance Optimized**: Uses database indexes for efficient querying
+
+## Architecture
+
+### Core Components
+
+1. **Audit Log Utility** (`src/lib/auditLog.js`)
+
+   - Core logging functions
+   - Query and statistics functions
+   - Action and resource type constants
+
+2. **API Endpoints** (`src/app/api/audit-logs/`)
+
+   - `/api/audit-logs` - Query audit logs with filtering
+   - `/api/audit-logs/stats` - Get audit log statistics
+
+3. **UI Components** (`src/components/AuditLogViewer.js`)
+
+   - Interactive audit log viewer
+   - Advanced filtering interface
+   - Statistics dashboard
+
+4. **Admin Pages** (`src/app/admin/audit-logs/`)
+   - Admin interface for viewing audit logs
+   - Role-based access control
+
+### Database Schema
+
+The audit logs are stored in the `audit_logs` table:
+
+```sql
+CREATE TABLE audit_logs (
+  id INTEGER PRIMARY KEY AUTOINCREMENT,
+  user_id TEXT,                    -- User who performed the action
+  action TEXT NOT NULL,            -- Action performed (see AUDIT_ACTIONS)
+  resource_type TEXT,              -- Type of resource affected
+  resource_id TEXT,                -- ID of the affected resource
+  ip_address TEXT,                 -- IP address of the user
+  user_agent TEXT,                 -- Browser/client information
+  timestamp TEXT DEFAULT CURRENT_TIMESTAMP,
+  details TEXT,                    -- Additional details (JSON)
+  FOREIGN KEY (user_id) REFERENCES users(id)
+);
+```
+
+## Usage
+
+### Basic Logging
+
+```javascript
+import { logAuditEvent, AUDIT_ACTIONS, RESOURCE_TYPES } from "@/lib/auditLog";
+
+// Log a simple action
+logAuditEvent({
+	action: AUDIT_ACTIONS.PROJECT_CREATE,
+	userId: "user123",
+	resourceType: RESOURCE_TYPES.PROJECT,
+	resourceId: "proj-456",
+	ipAddress: req.ip,
+	userAgent: req.headers["user-agent"],
+	details: {
+		project_name: "New Project",
+		project_number: "NP-001",
+	},
+});
+```
+
+### API Route Integration
+
+```javascript
+import { logApiAction, AUDIT_ACTIONS, RESOURCE_TYPES } from "@/lib/auditLog";
+
+export async function POST(req) {
+	const data = await req.json();
+
+	// Perform the operation
+	const result = createProject(data);
+
+	// Log the action
+	logApiAction(
+		req,
+		AUDIT_ACTIONS.PROJECT_CREATE,
+		RESOURCE_TYPES.PROJECT,
+		result.id.toString(),
+		req.session,
+		{ projectData: data }
+	);
+
+	return NextResponse.json({ success: true, id: result.id });
+}
+```
+
+### Querying Audit Logs
+
+```javascript
+import { getAuditLogs, getAuditLogStats } from "@/lib/auditLog";
+
+// Get recent logs
+const recentLogs = getAuditLogs({
+	limit: 50,
+	orderBy: "timestamp",
+	orderDirection: "DESC",
+});
+
+// Get logs for a specific user
+const userLogs = getAuditLogs({
+	userId: "user123",
+	startDate: "2025-01-01T00:00:00Z",
+	endDate: "2025-12-31T23:59:59Z",
+});
+
+// Get statistics
+const stats = getAuditLogStats({
+	startDate: "2025-01-01T00:00:00Z",
+	endDate: "2025-12-31T23:59:59Z",
+});

+}
+```
+
+## Access Control
+
+Audit logs are restricted to users with the following roles:
+
+- `admin` - Full access to all audit logs
+- `project_manager` - Full access to all audit logs
+
+Other users cannot access audit logs.
+
+## Testing
+
+Run the audit logging test script:
+
+```bash
+node test-audit-logging.mjs
+```
+
+This will:
+
+1. Create sample audit events
+2. Test querying and filtering
+3. Verify statistics generation
+4. Test date range filtering
+
+## Integration Status
+
+The audit logging system has been integrated into the following API routes:
+
+✅ **Authentication** (`src/lib/auth.js`)
+
+- Login success/failure tracking
+- Account lockout logging
+
+✅ **Projects** (`src/app/api/projects/`)
+
+- Project CRUD operations
+- List view access
+
+✅ **Notes** (`src/app/api/notes/`)
+
+- Note creation, updates, and deletion
+
+🔄 **Pending Integration:**
+
+- Tasks API
+- Project Tasks API
+- Contracts API
+- User management API
+
+## Performance Considerations
+
+- Database indexes are created on frequently queried fields
+- Large result sets are paginated
+- Statistics queries are optimized for common use cases
+- Failed operations are logged to prevent data loss
+
+## Security Features
+
+- IP address tracking for forensic analysis
+- User agent logging for client identification
+- Failed authentication attempt tracking
+- Detailed change logging for sensitive operations
+- Role-based access control for audit log viewing
+
+## Maintenance
+
+### Log Retention
+
+Consider implementing log retention policies:
+
+```sql
+-- Delete audit logs older than 1 year
+DELETE FROM audit_logs
+WHERE timestamp < datetime('now', '-1 year');
+```
+
+### Monitoring
+
+Monitor audit log growth and performance:
+
+```sql
+-- Check audit log table size
+SELECT COUNT(*) as total_logs,
+       MIN(timestamp) as oldest_log,
+       MAX(timestamp) as newest_log
+FROM audit_logs;
+
+-- Check most active users
+SELECT user_id, COUNT(*) as activity_count
+FROM audit_logs
+WHERE timestamp > datetime('now', '-30 days')
+GROUP BY user_id
+ORDER BY activity_count DESC
+LIMIT 10;
+```
+
+## Future Enhancements
+
+- Real-time audit log streaming
+- Advanced analytics and reporting
+- Integration with external SIEM systems
+- Automatic anomaly detection
+- Compliance reporting templates
+- Log export functionality

-## Security Best Practices
+## Current Working Features
 
-### 1. Password Security
-- Minimum 8 characters
-- Require special characters, numbers
-- Hash with bcrypt (cost factor 12+)
-- Implement password history
+### 🔐 Authentication System
 
-### 2. Session Security
-- Secure cookies
-- Session rotation
-- Timeout handling
-- Device tracking
+- **Login/Logout**: Fully functional with NextAuth.js
+- **Session Management**: JWT-based with 30-day expiration
+- **Password Security**: bcrypt hashing with salt rounds
+- **Account Lockout**: 5 failed attempts = 15-minute lockout
+- **Role System**: 4-tier hierarchy (admin, project_manager, user, read_only)
 
-### 3. API Security
-- Input validation on all endpoints
-- SQL injection prevention (prepared statements)
-- XSS protection
-- CSRF tokens
+### 🛡️ Authorization System
 
-### 4. Audit & Monitoring
-- Log all authentication events
-- Monitor failed login attempts
-- Track permission changes
-- Alert on suspicious activity
+- **API Protection**: All major endpoints require authentication
+- **Role-Based Access**: Different permission levels per endpoint
+- **Middleware**: Clean abstraction with helper functions
+- **Session Validation**: Automatic session verification
 
-## Testing Strategy
+### 📱 User Interface
 
-### 1. Authentication Tests
-- Valid/invalid login attempts
-- Password reset functionality
-- Session expiration
-- Account lockout
+- **Navigation**: Context-aware with user info and sign-out
+- **Auth Pages**: Professional sign-in form with error handling
+- **Role Integration**: Admin users see additional menu items
+- **Responsive**: Works across device sizes
 
-### 2. Authorization Tests
-- Role-based access control
-- API endpoint protection
-- Resource-level permissions
-- Privilege escalation attempts
+### 🗄️ Database Security
 
-### 3. Security Tests
-- SQL injection attempts
-- XSS attacks
-- CSRF attacks
-- Rate limiting
+- **User Management**: Complete CRUD with proper validation
+- **Audit Schema**: Ready for comprehensive logging
+- **Indexes**: Optimized for performance
+- **Constraints**: Role validation and data integrity
 
-## Deployment Considerations
+## Next Priority Tasks
 
-### 1. Environment Variables
-- Use strong, random secrets
-- Different keys per environment
-- Secure secret management
+1. **Complete Auth UI** (High Priority)
 
-### 2. Database Security
-- Regular backups
-- Encryption at rest
-- Network security
-- Access logging
+   - Sign-out confirmation page
+   - Unauthorized access page
+   - Enhanced error handling
 
-### 3. Application Security
-- HTTPS enforcement
-- Security headers
-- Content Security Policy
-- Regular security updates
+2. **Admin User Management** (High Priority)
 
-## Migration Strategy

+# Edge Runtime Compatibility Fix - Final Solution
+
+## Problem Resolved
+
+The audit logging system was causing "Edge runtime does not support Node.js 'fs' module" errors because the `better-sqlite3` database module was being loaded in Edge Runtime contexts through static imports.
+
+## Root Cause
+
+The middleware imports `auth.js` → which imported `auditLog.js` → which had a static import of `db.js` → which imports `better-sqlite3`. This caused the entire SQLite module to be loaded even in Edge Runtime where it's not supported.
+
+## Final Solution
+
+### 1. Created Safe Audit Logging Module
+
+**File: `src/lib/auditLogSafe.js`**
+
+This module provides:
+
+- ✅ **No static database imports** - completely safe for Edge Runtime
+- ✅ **Runtime detection** - automatically detects Edge vs Node.js
+- ✅ **Graceful fallbacks** - console logging in Edge, database in Node.js
+- ✅ **Constants always available** - `AUDIT_ACTIONS` and `RESOURCE_TYPES`
+- ✅ **Async/await support** - works with modern API patterns
+
+```javascript
+// Safe import that never causes Edge Runtime errors
+import {
+	logAuditEventSafe,
+	AUDIT_ACTIONS,
+	RESOURCE_TYPES,
+} from "./auditLogSafe.js";
+
+// Works in any runtime
+await logAuditEventSafe({
+	action: AUDIT_ACTIONS.LOGIN,
+	userId: "user123",
+	resourceType: RESOURCE_TYPES.SESSION,
+});
+```
+
+### 2. Updated All Imports
+
+**Files Updated:**
+
+- `src/lib/auth.js` - Authentication logging
+- `src/app/api/projects/route.js` - Project operations
+- `src/app/api/projects/[id]/route.js` - Individual project operations
+- `src/app/api/notes/route.js` - Note operations
+
+**Before:**
+
+```javascript
+import { logApiAction, AUDIT_ACTIONS } from "@/lib/auditLog.js"; // ❌ Causes Edge Runtime errors
+```
+
+**After:**
+
+```javascript
+import { logApiActionSafe, AUDIT_ACTIONS } from "@/lib/auditLogSafe.js"; // ✅ Edge Runtime safe
+```
+
+### 3. Runtime Behavior
+
+#### Edge Runtime
+
+- **Detection**: Automatic via `typeof EdgeRuntime !== 'undefined'`
+- **Logging**: Console output only
+- **Performance**: Zero database overhead
+- **Errors**: None - completely safe
+
+#### Node.js Runtime
+
+- **Detection**: Automatic fallback when Edge Runtime not detected
+- **Logging**: Full database functionality via dynamic import
+- **Performance**: Full audit trail with database persistence
+- **Errors**: Graceful handling with console fallback
+
+### 4. Migration Pattern
+
+The safe module uses a smart delegation pattern:
+
+```javascript
+// In Edge Runtime: Console logging only
+console.log(`[Audit] ${action} by user ${userId}`);
+
+// In Node.js Runtime: Try database, fallback to console
+try {
+	const auditModule = await import("./auditLog.js");
+	auditModule.logAuditEvent({ ...params });
+} catch (dbError) {
+	console.log("[Audit] Database logging failed, using console fallback");
+}
+```
+
+## Files Structure
+
+```
+src/lib/
+├── auditLog.js          # Original - Node.js only (database operations)
+├── auditLogSafe.js      # New - Universal (Edge + Node.js compatible)
+├── auditLogEdge.js      # Alternative - Edge-specific with API calls
+└── auth.js              # Updated to use safe imports
+```
+
+## Testing
+
+Run the compatibility test:
+
+```bash
+node test-safe-audit-logging.mjs
+```
+
+**Expected Output:**
+
+```
+✅ Safe module imported successfully
+✅ Edge Runtime logging successful (console only)
+✅ Node.js Runtime logging successful (database + console)
+✅ Constants accessible
+```
+
+## Verification Checklist
+
+✅ **No more Edge Runtime errors**  
+✅ **Middleware works without database dependencies**  
+✅ **Authentication logging works in all contexts**  
+✅ **API routes maintain full audit functionality**  
+✅ **Constants available everywhere**  
+✅ **Graceful degradation in Edge Runtime**  
+✅ **Full functionality in Node.js Runtime**
+
+## Performance Impact
+
+- **Edge Runtime**: Minimal - only console logging
+- **Node.js Runtime**: Same as before - full database operations
+- **Import cost**: Near zero - no static database imports
+- **Memory usage**: Significantly reduced in Edge Runtime
+
+## Migration Guide
+
+To update existing code:
+
+1. **Replace imports:**
+
+   ```javascript
+   // Old
+   import { logApiAction } from "@/lib/auditLog.js";
+
+   // New
+   import { logApiActionSafe } from "@/lib/auditLogSafe.js";
+   ```
+
+2. **Update function calls:**
+
+   ```javascript
+   // Old
+   logApiAction(req, action, type, id, session, details);
+
+   // New
+   await logApiActionSafe(req, action, type, id, session, details);
+   ```
+
+3. **Add runtime exports** (for API routes):
+   ```javascript
+   export const runtime = "nodejs"; // For database-heavy routes
+   ```
+
+## Best Practices Applied
+
+1. **Separation of Concerns**: Safe module for universal use, full module for Node.js
+2. **Dynamic Imports**: Database modules loaded only when needed
+3. **Runtime Detection**: Automatic environment detection
+4. **Graceful Degradation**: Meaningful fallbacks in constrained environments
+5. **Error Isolation**: Audit failures don't break main application flow
+
+The application now handles both Edge and Node.js runtimes seamlessly with zero Edge Runtime errors! 🎉

+# Final Edge Runtime Fix - Audit Logging System
+
+## ✅ **Issue Resolved**
+
+The Edge Runtime error has been completely fixed! The audit logging system now works seamlessly across all Next.js runtime environments.
+
+## 🔧 **Final Implementation**
+
+### **Problem Summary**
+
+- Edge Runtime was trying to load `better-sqlite3` (Node.js fs module)
+- Static imports in middleware caused the entire dependency chain to load
+- `middleware.js` → `auth.js` → `auditLog.js` → `db.js` → `better-sqlite3`
+
+### **Solution Implemented**
+
+#### 1. **Made All Functions Async**
+
+```javascript
+// Before: Synchronous with require()
+export function logAuditEvent() {
+	const { default: db } = require("./db.js");
+}
+
+// After: Async with dynamic import
+export async function logAuditEvent() {
+	const { default: db } = await import("./db.js");
+}
+```
+
+#### 2. **Runtime Detection & Graceful Fallbacks**
+
+```javascript
+export async function logAuditEvent(params) {
+	try {
+		// Edge Runtime detection
+		if (
+			typeof EdgeRuntime !== "undefined" ||
+			process.env.NEXT_RUNTIME === "edge"
+		) {
+			console.log(`[Audit Log - Edge Runtime] ${action} by user ${userId}`);
+			return; // Graceful exit
+		}
+
+		// Node.js Runtime: Full database functionality
+		const { default: db } = await import("./db.js");
+		// ... database operations
+	} catch (error) {
+		console.error("Failed to log audit event:", error);
+		// Non-breaking error handling
+	}
+}
+```
+
+#### 3. **Safe Wrapper Module (`auditLogSafe.js`)**
+
+```javascript
+export async function logAuditEventSafe(params) {
+	console.log(`[Audit] ${action} by user ${userId}`); // Always log to console
+
+	if (typeof EdgeRuntime !== "undefined") {
+		return; // Edge Runtime: Console only
+	}
+
+	try {
+		const auditModule = await import("./auditLog.js");
+		await auditModule.logAuditEvent(params); // Node.js: Database + console
+	} catch (error) {
+		console.log("[Audit] Database logging failed, using console fallback");
+	}
+}
+```
+
+## 🎯 **Runtime Behavior**
+
+| Runtime     | Behavior                 | Database | Console | Errors                 |
