 ## Project Overview
 
-This is an API Key Management Service (KMS) built with Go backend and React TypeScript frontend. The system manages API keys, user authentication, permissions, and provides both static tokens and user JWT tokens with hierarchical permission scopes.
+Skybridge is an all-in-one "startup starterpack" monolith application designed to provide everything needed to start a software company with a single platform. Built with a microfrontend architecture, it combines multiple business-critical services including API key management, user authentication, permissions, and a modular plugin system for additional business applications.
 
-## Architecture
+**Key Technologies:**
+- **Backend**: Go 1.23+ with Gin router, PostgreSQL, JWT tokens  
+- **Frontend**: React 18+ with TypeScript, Mantine UI components
+- **Module Federation**: Webpack 5 Module Federation for plugin architecture
+- **Infrastructure**: Podman/Docker Compose, Nginx
+- **Security**: HMAC token signing, RBAC permissions, rate limiting
 
-The project follows clean architecture principles with clear separation:

 ## Development Commands
 
-### Go Backend
+### Startup Platform Development
 
 ```bash
-# Run the server locally
-go run cmd/server/main.go
+# Start complete platform in development mode (run in separate terminals)
 
-# Build the binary
-go build -o api-key-service ./cmd/server
+# Terminal 1: Main Dashboard Shell
+cd web
+npm install
+npm run dev        # Central dashboard on port 3000
 
-# Run tests
+# Terminal 2: KMS Business Module
+cd kms/web
+npm install  
+npm run dev        # API Key Management on port 3002
+
+# Terminal 3: Demo/Template Module
+cd demo  
+npm install
+npm run dev        # Plugin template on port 3001
+
+# Production build
+npm run build      # In each business module directory
+```
+
+### Platform Backend Development
+
+```bash
+# Start core platform backend with authentication services
+cd kms
+INTERNAL_HMAC_KEY=test-hmac-key JWT_SECRET=test-jwt-secret AUTH_SIGNING_KEY=test-signing-key go run cmd/server/main.go
+
+# Build platform backend
+go build -o platform-server ./cmd/server
+
+# Run platform tests
 go test -v ./test/...
 
-# Run tests with coverage
-go test -v -coverprofile=coverage.out ./test/...
-go tool cover -html=coverage.out -o coverage.html
-
-# Run specific test suites
-go test -v ./test/ -run TestHealthEndpoints
+# Test specific business modules
 go test -v ./test/ -run TestApplicationCRUD
 go test -v ./test/ -run TestStaticTokenWorkflow
-go test -v ./test/ -run TestConcurrentRequests
 ```
 
-### React Frontend
+### Full Platform Deployment (Recommended)
+
+**CRITICAL**: This project uses `podman-compose`, not `docker-compose`.
 
 ```bash
-# Navigate to frontend directory
-cd kms-frontend
+# Start complete startup platform (database, API, all business modules)
+podman-compose up -d
 
-# Install dependencies
-npm install
+# Start with forced rebuild after code changes  
+podman-compose up -d --build
 
-# Start development server
-npm start
+# View platform logs
+podman-compose logs -f kms-api-service
+podman-compose logs -f postgres
 
-# Build for production
-npm run build
+# Stop entire platform
+podman-compose down
 
-# Run tests
-npm test
+# Check platform health
+curl http://localhost:8081/health
 ```
 
-### Docker & Development Environment
+### Database Operations
+
+**CRITICAL**: All database operations use `podman exec` commands.
 
 ```bash
-# Start all services (PostgreSQL, API, Nginx, Frontend)
-docker-compose up -d
+# Access database shell
+podman exec -it kms-postgres psql -U postgres -d kms
 
-# Check service health
-curl http://localhost/health
+# Run SQL commands via exec
+podman exec -it kms-postgres psql -U postgres -c "SELECT * FROM applications LIMIT 5;"
 
-# View logs
-docker-compose logs -f
+# Check tables
+podman exec -it kms-postgres psql -U postgres -d kms -c "\dt"
 
-# Stop services  
-docker-compose down
+# Reset test database  
+podman exec -it kms-postgres psql -U postgres -c "DROP DATABASE IF EXISTS kms_test; CREATE DATABASE kms_test;"
 ```
 
-## Database Setup
+## Key Architecture Patterns
 
-The project uses PostgreSQL with automatic migrations. For local development:
+### Business Module Plugin System
+- **Shell Dashboard** (`web/webpack.config.js`): Central hub consuming all business modules
+- **Business Modules** (`kms/web/webpack.config.js`, `demo/webpack.config.js`): Independent applications exposing functionality
+- **Shared Infrastructure**: React, Mantine, icons shared across all business modules
 
+### Startup Platform Routing
+- **Central routing**: `/app/{businessModule}/*` handled by shell dashboard
+- **Module autonomy**: Each business application handles internal navigation independently  
+- **Isolated contexts**: No React Router conflicts between business modules
+
+### Core Authentication System (KMS Module)
+The platform's authentication system uses **exact permission names** (not wildcards):
+- **Application management**: `app.read`, `app.write`, `app.delete`
+- **Token operations**: `token.read`, `token.create`, `token.revoke` 
+- **Repository access**: `repo.read`, `repo.write`, `repo.admin`
+- **Permission management**: `permission.read`, `permission.write`, `permission.grant`, `permission.revoke`
+
+### Business Application Types
+Valid application configurations for the platform:
+- `"static"` - Service-to-service authentication for business modules
+- `"user"` - User authentication for startup team members
+
+### Ownership Models
+Platform supports different ownership structures:
+- `"individual"` - Individual founder/employee ownership
+- `"team"` - Team/department ownership
+
+## Important Development Notes
+
+### Business Module Development
+- **Port allocation**: Dashboard:3000, Demo:3001, KMS:3002, [Future modules:3003+]
+- **Environment variables**: All business modules require `webpack.DefinePlugin` for process.env
+- **Shared dependencies**: Must match versions across all business modules
+- **Navigation**: Use `window.history.pushState()` and custom events for inter-module routing
+- **Local Development**: Do not start webpack microfrontends as they are already running locally
+
+### Platform API Integration
+- **Base URL**: `http://localhost:8080` (development)
+- **Authentication**: Header-based with `X-User-Email: admin@example.com`
+- **Duration format**: Convert human-readable formats like "24h" to seconds (86400) for API
+- **Permission validation**: Use exact permission names from database, not wildcards
+
+### Startup Platform UI Standards
+- **UI Framework**: Mantine v7.0.0 (consistent across all business modules)
+- **Icons**: Tabler Icons React (shared icon system)
+- **Forms**: Mantine Form with validation (standardized form handling)
+- **Notifications**: Mantine Notifications (unified notification system)
+
+### Critical Platform Configuration
 ```bash
-# Create development database
-psql -U postgres -c "CREATE DATABASE kms;"
+# Platform Backend Environment Variables (Required)
+INTERNAL_HMAC_KEY=<secure-hmac-key-32-chars-min>
+JWT_SECRET=<secure-jwt-secret-32-chars-min>  
+AUTH_SIGNING_KEY=<secure-auth-key-32-chars-min>
 
-# Create test database  
-psql -U postgres -c "CREATE DATABASE kms_test;"
-```
-
-## Testing
-
-### End-to-End Testing
-
-```bash
-# Run comprehensive E2E tests with curl
-./test/e2e_test.sh
-
-# Test against different server
-BASE_URL=http://localhost:8080 USER_EMAIL=admin@example.com ./test/e2e_test.sh
-```
-
-### Test Environments
-
-The service provides different test user contexts on different ports:
-- Port 80: Regular user (`test@example.com`) 
-- Port 8081: Admin user (`admin@example.com`)
-- Port 8082: Limited user (`limited@example.com`)
-
-## Key Configuration
-
-Environment variables for configuration:
-
-```bash
-# Database
-DB_HOST=localhost
-DB_PORT=5432  
+# Platform Database
+DB_HOST=postgres  # Use 'postgres' for containers
+DB_PORT=5432
 DB_NAME=kms
-DB_USER=postgres
+DB_USER=postgres  
 DB_PASSWORD=postgres
 
-# Server
-SERVER_HOST=0.0.0.0
-SERVER_PORT=8080
-
-# Authentication  
+# Startup Platform Authentication
 AUTH_PROVIDER=header
 AUTH_HEADER_USER_EMAIL=X-User-Email
-
-# Security
-RATE_LIMIT_ENABLED=true
-RATE_LIMIT_RPS=100
-RATE_LIMIT_BURST=200
 ```
 
-## API Structure
+### Testing & Debugging
+- **Platform E2E Tests**: `./kms/test/e2e_test.sh` for core authentication system
+- **Test Users**: `admin@example.com`, `test@example.com`, `limited@example.com`
+- **Service Ports**: API:8080, Nginx:8081, Dashboard:3000, DB:5432
+- **Debug Business Modules**: Check browser network tab for remoteEntry.js loading from each module
 
-The API provides:
-- Health checks (`/health`, `/ready`)
-- Authentication (`/api/login`, `/api/verify`, `/api/renew`)
-- Application management (`/api/applications`)
-- Token management (`/api/applications/{id}/tokens`)
-- Permission hierarchies (repo.read, app.write, internal.admin, etc.)
+### Build & Deployment
+- **Development**: Run dashboard shell + all business modules + platform backend
+- **Container Issues**: Use `podman-compose build --no-cache` if changes don't appear
+- **Module Federation**: All business modules must be running for dashboard to load them
+- **Production**: Build all business modules and serve via nginx with proper CORS headers
 
-## Code Patterns
+## Security Considerations
+- All platform tokens use HMAC signing with secure keys
+- Permission validation at both API and UI levels across all business modules
+- Rate limiting and comprehensive audit logging for startup compliance
+- CORS configured for secure business module communication
+- Never commit secrets or API keys to repository
 
-### Backend Patterns
-- Repository pattern for data access with interfaces
-- Service layer for business logic with dependency injection
-- Middleware chain for authentication, logging, security
-- Structured error handling with custom error types
-- Comprehensive logging with zap structured logger
+## Adding New Business Modules
+To extend the startup platform with new business applications (CRM, billing, analytics, etc.):
 
-### Frontend Patterns  
-- React functional components with TypeScript
-- Ant Design component library
-- Context API for authentication state
-- Axios for API communication
-- React Router for navigation
-
-## Permission System
-
-Hierarchical permission scopes:
-- `internal.*` - System operations
-- `app.*` - Application management  
-- `token.*` - Token operations
-- `repo.*` - Repository access (example domain)
-- `permission.*` - Permission management
-
-Parent permissions inherit child permissions (e.g., `repo` includes `repo.read` and `repo.write`).
-
-## Database Schema
-
-Key tables:
-- `applications` - Application definitions with HMAC keys
-- `static_tokens` - Static API tokens  
-- `available_permissions` - Permission catalog
-- `granted_permissions` - Token-permission relationships
-- `user_sessions` - User session tracking
-
-## Development Notes
-
-- The backend uses interfaces throughout for testability and dependency injection
-- Database migrations run automatically on startup
-- Rate limiting is configurable per endpoint  
-- All operations include audit logging with user attribution
-- Token security uses HMAC signing with rotation capabilities
-- Frontend uses protected routes with authentication context
-- E2E tests provide comprehensive API coverage with curl

+  }
+}
+```
+
+### Typical Integration Pattern
+```tsx
+// Before: 200+ lines of custom form code
+// After: Clean configuration
+const fields: FormField[] = [
+  { name: 'email', type: 'email', required: true },
+  { name: 'role', type: 'select', options: [...] }
+];
+
+return (
+  <FormSidebar
+    fields={fields}
+    onSubmit={handleSubmit}
+    editItem={editItem}
+  />
+);
+```
+
+## Current Status
+
+### ✅ Completed Tasks
+1. ✅ Web components library built and distributed
+2. ✅ All 5 microfrontends successfully integrated
+3. ✅ FormSidebar components refactored across platform

+
+## Additional Shared Component Integration (Final Phase)
+
+### ✅ SidebarLayout Standardization - **NEW**
+- **Status**: Completed across all microfrontends with sidebars
+- **Problem Solved**: Fixed sidebar overlay behavior where main content was covered instead of shrinking
+- **New Components Added**:
+  - `SidebarLayout`: Manages main content area resizing when sidebars open
+  - `Sidebar` (enhanced): Added `layoutMode` prop for integration with SidebarLayout
+- **Components Updated**:
+  - `Applications.tsx` (KMS): Replaced Stack with manual margins → SidebarLayout + enhanced Sidebar
+  - `UserManagement.tsx` (User): Replaced Stack with manual margins → SidebarLayout  
+  - `App.tsx` (FaaS): Replaced Stack with manual margins → Optimized margin calculation for existing fixed sidebars
+- **Benefits**: Main content now properly shrinks to accommodate sidebars, providing better UX and preventing content from being hidden
+
+## Additional Shared Component Integration (Previous Phase)
+
+### ✅ StatusBadge Integration
+- **Status**: Completed across FaaS and KMS modules
+- **Components Updated**:
+  - `ExecutionModal.tsx` & `ExecutionSidebar.tsx` (FaaS): Replaced duplicate `getStatusColor` function with `ExecutionStatusBadge`
+  - `Audit.tsx` (KMS): Replaced custom status logic with standardized `StatusBadge` component
+- **Benefits**: Eliminated duplicate status color mapping logic, consistent status display across platform
+- **Code Reduction**: ~30 lines of duplicate status logic removed per component
+
+### ✅ Pattern Consolidation Analysis
+- **Duplicate Status Logic**: Found and replaced in 4+ components across microfrontends
+- **Shared Loading States**: Available but not universally adopted (complex implementation differences)
+- **Empty State Patterns**: Standardized components available for future adoption
+- **Form Sidebar Usage**: Already well-adopted in User and Application management
+
+## Updated Architecture Benefits
+
+### 🎯 Enhanced Code Standardization
+- **Consistent Status Indicators**: All status badges now use standardized color mapping
+- **Unified Badge Variants**: Execution, severity, runtime, and application type badges standardized

+
+### 📉 Final Code Reduction Metrics
+- **UserSidebar**: 250 lines → 80 lines (70% reduction)
+- **Applications Table**: Complex implementation → clean DataTable configuration
+- **Status Logic**: ~120 lines of duplicate status functions eliminated
+- **Sidebar Layout Logic**: ~90 lines of manual margin management replaced with declarative SidebarLayout
+- **Overall Platform**: Estimated 70-80% reduction in form/table/status/layout boilerplate
+
+### 🔧 Maintainability Improvements
+- **Centralized Status Logic**: All status colors managed in single StatusBadge component
+- **Standardized Layout Behavior**: SidebarLayout ensures consistent sidebar behavior across all microfrontends
+- **Type Safety**: StatusBadge variants and SidebarLayout props ensure consistent usage patterns
+- **Easy Updates**: Status color changes and sidebar behavior improvements propagate automatically to all components
+

-## Schema Overview
-
-The KMS database schema is designed around core entities that manage applications, tokens, permissions, and user sessions. The schema follows PostgreSQL best practices with proper normalization, constraints, and indexing strategies.
-
-### Core Entities
-- **Applications**: Central configuration for API key management
-- **Static Tokens**: Long-lived API tokens with HMAC signatures
-- **User Sessions**: JWT token tracking with metadata
-- **Available Permissions**: Hierarchical permission catalog
-- **Granted Permissions**: Token-permission relationships
-- **Audit Logs**: Complete audit trail of all operations
-
-### Design Principles
-- **Normalized Design**: Reduces data redundancy
-- **Referential Integrity**: Foreign key constraints ensure consistency
-- **Audit Trail**: Complete history of all operations
-- **Performance Optimized**: Strategic indexing for common queries
-- **Security First**: Sensitive data protection and access controls

-
-### Static Tokens Table
-
-Long-lived API tokens with HMAC-based authentication.
-
-```sql
-CREATE TABLE static_tokens (
-    id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
-    app_id VARCHAR(100) NOT NULL REFERENCES applications(app_id) ON DELETE CASCADE,
-    owner_type VARCHAR(20) NOT NULL CHECK (owner_type IN ('individual', 'team')),
-    owner_name VARCHAR(255) NOT NULL,
-    owner_owner VARCHAR(255) NOT NULL,
-    key_hash TEXT NOT NULL UNIQUE,
-    type VARCHAR(10) NOT NULL DEFAULT 'hmac' CHECK (type = 'hmac'),
-    created_at TIMESTAMP WITH TIME ZONE NOT NULL DEFAULT NOW(),
-    updated_at TIMESTAMP WITH TIME ZONE NOT NULL DEFAULT NOW()
-);
-```
-
-#### Security Features
-- **`key_hash`**: BCrypt hash of the actual token (cost 14)
-- **Unique constraint**: Prevents token duplication
-- **Cascade deletion**: Tokens deleted when application is removed
-- **Owner tracking**: Links tokens to their creators
-
-### User Sessions Table
-
-JWT token session tracking with comprehensive metadata.
-
-```sql
-CREATE TABLE user_sessions (
-    id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
-    user_id VARCHAR(255) NOT NULL,
-    app_id VARCHAR(100) NOT NULL REFERENCES applications(app_id) ON DELETE CASCADE,
-    session_token VARCHAR(255) NOT NULL,
-    permissions TEXT NOT NULL DEFAULT '[]', -- JSON array
-    expires_at TIMESTAMP WITH TIME ZONE NOT NULL,
-    max_valid_at TIMESTAMP WITH TIME ZONE NOT NULL,

-    metadata JSONB DEFAULT '{}',
-    active BOOLEAN NOT NULL DEFAULT true,
-    created_at TIMESTAMP WITH TIME ZONE NOT NULL DEFAULT NOW(),
-    updated_at TIMESTAMP WITH TIME ZONE NOT NULL DEFAULT NOW(),
-    last_used_at TIMESTAMP WITH TIME ZONE,
-    
-    -- Constraints
-    CONSTRAINT valid_session_times CHECK (max_valid_at >= expires_at),
-    CONSTRAINT valid_permissions CHECK (permissions::json IS NOT NULL)
-);
-```
-
-#### Session Management Features
-- **Session tracking**: Complete session lifecycle management
-- **Multi-provider support**: Tracks authentication method
-- **Permission storage**: JSON array of granted permissions
-- **Activity tracking**: Last used timestamp for session cleanup
-- **Flexible metadata**: Provider-specific data storage
-
-### Available Permissions Table
-
-Hierarchical permission catalog with system and custom permissions.
-
-```sql
-CREATE TABLE available_permissions (
-    id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
-    scope VARCHAR(255) NOT NULL UNIQUE,
-    name VARCHAR(255) NOT NULL,
-    description TEXT,
-    category VARCHAR(100) NOT NULL DEFAULT 'custom',
-    parent_scope VARCHAR(255) REFERENCES available_permissions(scope) ON DELETE SET NULL,
-    is_system BOOLEAN NOT NULL DEFAULT false,
-    created_at TIMESTAMP WITH TIME ZONE NOT NULL DEFAULT NOW(),
-    created_by VARCHAR(255) NOT NULL,
-    updated_at TIMESTAMP WITH TIME ZONE NOT NULL DEFAULT NOW(),
-    updated_by VARCHAR(255) NOT NULL,
-    
-    -- Constraints
-    CONSTRAINT scope_format CHECK (scope ~ '^[a-zA-Z][a-zA-Z0-9._]*[a-zA-Z0-9]$'),
-    CONSTRAINT no_self_reference CHECK (scope != parent_scope)
-);
-```
-
-#### Permission Hierarchy Features
-- **Hierarchical structure**: Parent-child permission relationships
-- **System permissions**: Built-in permissions that cannot be deleted
-- **Flexible scoping**: Dot-notation permission scopes
-- **Audit tracking**: Creation and modification history
-
-### Granted Permissions Table
-
-Token-permission relationship management with revocation support.
-
-```sql
-CREATE TABLE granted_permissions (
-    id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
-    token_type VARCHAR(10) NOT NULL CHECK (token_type IN ('static', 'user')),
-    token_id UUID NOT NULL,
-    permission_id UUID NOT NULL REFERENCES available_permissions(id) ON DELETE CASCADE,
-    scope VARCHAR(255) NOT NULL, -- Denormalized for performance
-    created_at TIMESTAMP WITH TIME ZONE NOT NULL DEFAULT NOW(),
-    created_by VARCHAR(255) NOT NULL,
-    revoked BOOLEAN NOT NULL DEFAULT false,
-    revoked_at TIMESTAMP WITH TIME ZONE,
-    revoked_by VARCHAR(255),
-    
-    -- Constraints
-    CONSTRAINT unique_token_permission UNIQUE (token_type, token_id, permission_id),
-    CONSTRAINT valid_revocation CHECK (
-        (revoked = false AND revoked_at IS NULL AND revoked_by IS NULL) OR
-        (revoked = true AND revoked_at IS NOT NULL AND revoked_by IS NOT NULL)
-    )
-);
-```
-
-#### Permission Grant Features

-
----
-
-## Security Considerations
-
-### Data Protection
-
-#### **Sensitive Data Handling**
-```sql
--- HMAC keys should be encrypted at application level
--- Token hashes use BCrypt with cost 14
--- Audit logs contain no sensitive data in plaintext
-
--- Row-level security (RLS) for multi-tenant isolation
-ALTER TABLE applications ENABLE ROW LEVEL SECURITY;
-ALTER TABLE static_tokens ENABLE ROW LEVEL SECURITY;
-ALTER TABLE user_sessions ENABLE ROW LEVEL SECURITY;
-
--- Example RLS policy for application isolation
-CREATE POLICY app_owner_policy ON applications
-FOR ALL TO app_user
-USING (owner_owner = current_setting('app.user_id'));
-```
-
-#### **Access Control**
-```sql
--- Database roles for different access patterns
-CREATE ROLE kms_api_service;
-CREATE ROLE kms_readonly;
-CREATE ROLE kms_admin;
-
--- Grant appropriate permissions
-GRANT SELECT, INSERT, UPDATE, DELETE ON applications TO kms_api_service;
-GRANT SELECT, INSERT, UPDATE, DELETE ON static_tokens TO kms_api_service;
-GRANT SELECT, INSERT, UPDATE, DELETE ON user_sessions TO kms_api_service;
-GRANT SELECT, INSERT, UPDATE, DELETE ON granted_permissions TO kms_api_service;
-GRANT SELECT, INSERT ON audit_logs TO kms_api_service;
-
--- Read-only access for reporting
-GRANT SELECT ON ALL TABLES IN SCHEMA public TO kms_readonly;
-
--- Admin access for maintenance
-GRANT ALL PRIVILEGES ON ALL TABLES IN SCHEMA public TO kms_admin;
-```
-
-### Audit and Compliance
-
-#### **Audit Triggers**
-```sql
--- Automatic audit logging trigger
-CREATE OR REPLACE FUNCTION audit_trigger_function()
-RETURNS TRIGGER AS $$
-BEGIN
-    INSERT INTO audit_logs (
-        user_id, action, resource_type, resource_id, 
-        old_values, new_values, ip_address
-    ) VALUES (
-        current_setting('app.user_id', true),
-        TG_OP,
-        TG_TABLE_NAME,
-        COALESCE(NEW.id, OLD.id)::text,
-        CASE WHEN TG_OP = 'DELETE' THEN row_to_json(OLD) ELSE NULL END,
-        CASE WHEN TG_OP = 'INSERT' THEN row_to_json(NEW) 
-             WHEN TG_OP = 'UPDATE' THEN row_to_json(NEW)
-             ELSE NULL END,
-        inet_client_addr()
-    );
-    RETURN COALESCE(NEW, OLD);
-END;
-$$ LANGUAGE plpgsql SECURITY DEFINER;
-
--- Apply audit trigger to sensitive tables
-CREATE TRIGGER audit_applications 
-AFTER INSERT OR UPDATE OR DELETE ON applications
-FOR EACH ROW EXECUTE FUNCTION audit_trigger_function();
-
-CREATE TRIGGER audit_static_tokens 
-AFTER INSERT OR UPDATE OR DELETE ON static_tokens
-FOR EACH ROW EXECUTE FUNCTION audit_trigger_function();
-
-CREATE TRIGGER audit_granted_permissions 
-AFTER INSERT OR UPDATE OR DELETE ON granted_permissions
-FOR EACH ROW EXECUTE FUNCTION audit_trigger_function();
-```
-
----
-
-## Migration Strategy
-
-### Migration Framework
-
-The KMS uses a custom Go migration system with the following structure:
-
-```
-migrations/
-├── 001_initial_schema.up.sql
-├── 001_initial_schema.down.sql
-├── 002_user_sessions.up.sql
-├── 002_user_sessions.down.sql
-├── 003_add_token_prefix.up.sql
-└── 003_add_token_prefix.down.sql
-```
-
-#### **Migration Management**
-```go
-// File: internal/database/migrations.go
-type Migration struct {
-    Version     int
-    Name        string
-    UpScript    string
-    DownScript  string
-    AppliedAt   time.Time
-}
-
-func RunMigrations(db *sql.DB, migrationsPath string) error {
-    // Create migration tracking table
-    createMigrationTable(db)
-    
-    // Get applied migrations
-    applied, err := getAppliedMigrations(db)
-    if err != nil {
-        return err
-    }
-    
-    // Run pending migrations
-    return runPendingMigrations(db, migrationsPath, applied)
-}
-```
-
-### Schema Versioning
-
-#### **Version Control**
-- **Sequential numbering**: 001, 002, 003...
-- **Descriptive names**: Clear migration purpose
-- **Rollback support**: Down scripts for every migration
-- **Atomic operations**: Each migration in a transaction
-
-#### **Migration Best Practices**
-```sql
--- Always start with BEGIN; and end with COMMIT;
-BEGIN;
-
--- Add new columns with default values
-ALTER TABLE applications 
-ADD COLUMN token_prefix VARCHAR(10) DEFAULT NULL;
-
--- Add constraints after data migration
-ALTER TABLE applications 
-ADD CONSTRAINT token_prefix_format 
-CHECK (token_prefix IS NULL OR token_prefix ~ '^[A-Z]{2,4}$');
-
--- Create indexes concurrently (outside transaction)
-COMMIT;
-
-CREATE INDEX CONCURRENTLY idx_applications_token_prefix 
-ON applications(token_prefix) WHERE token_prefix IS NOT NULL;
-```
-
----
-
-## Query Patterns
-
-### Common Query Patterns
-
-#### **Application Queries**
-```sql
--- Get application with ownership check
-SELECT a.* FROM applications a 
-WHERE a.app_id = $1 
-  AND (a.owner_owner = $2 OR $2 = 'admin@example.com');
-
--- List applications for user with pagination
-SELECT a.app_id, a.app_link, a.owner_name, a.created_at
-FROM applications a 
-WHERE a.owner_owner = $1 
-ORDER BY a.created_at DESC 
-LIMIT $2 OFFSET $3;
-```
-
-#### **Token Verification Queries**
-```sql
--- Verify static token
-SELECT st.id, st.app_id, st.key_hash
-FROM static_tokens st 
-WHERE st.app_id = $1;
-
--- Get token permissions
-SELECT ap.scope 
-FROM granted_permissions gp
-JOIN available_permissions ap ON gp.permission_id = ap.id
-WHERE gp.token_type = 'static' 
-  AND gp.token_id = $1 
-  AND gp.revoked = false;
-```
-
-#### **Session Management Queries**
-```sql
--- Get active user session
-SELECT us.* FROM user_sessions us
-WHERE us.user_id = $1 
-  AND us.app_id = $2 
-  AND us.active = true 
-  AND us.expires_at > NOW()
-ORDER BY us.created_at DESC 
-LIMIT 1;
-
--- Clean up expired sessions
-UPDATE user_sessions 
-SET active = false, updated_at = NOW()
-WHERE active = true 
-  AND expires_at < NOW();
-```
-
-#### **Permission Evaluation Queries**
-```sql
--- Check user permission
-WITH user_permissions AS (
-    SELECT DISTINCT ap.scope
-    FROM user_sessions us
-    JOIN granted_permissions gp ON gp.token_type = 'user'
-    JOIN available_permissions ap ON gp.permission_id = ap.id
-    WHERE us.user_id = $1 
-      AND us.app_id = $2 
-      AND us.active = true 
-      AND us.expires_at > NOW()
-      AND gp.revoked = false
-)
-SELECT EXISTS(
-    SELECT 1 FROM user_permissions 
-    WHERE scope = $3 OR scope = split_part($3, '.', 1)
-);
-
--- Get permission hierarchy
-WITH RECURSIVE permission_tree AS (
-    -- Base case: root permissions
-    SELECT id, scope, name, parent_scope, 0 as level
-    FROM available_permissions 
-    WHERE parent_scope IS NULL
-    
-    UNION ALL
-    
-    -- Recursive case: child permissions
-    SELECT ap.id, ap.scope, ap.name, ap.parent_scope, pt.level + 1
-    FROM available_permissions ap
-    JOIN permission_tree pt ON ap.parent_scope = pt.scope
-)
-SELECT * FROM permission_tree ORDER BY level, scope;
-```
-
-### Performance Tuning
-
-#### **Query Optimization**
-```sql
--- Use EXPLAIN ANALYZE for query planning
-EXPLAIN (ANALYZE, BUFFERS) 
-SELECT st.id FROM static_tokens st 
-WHERE st.app_id = 'test-app' AND st.key_hash = 'hash123';
-
--- Optimize with covering indexes
-CREATE INDEX idx_static_tokens_covering 
-ON static_tokens(app_id, key_hash) 
-INCLUDE (id, created_at);
-
--- Use partial indexes for frequent filters
-CREATE INDEX idx_active_sessions_partial 
-ON user_sessions(user_id, app_id, expires_at) 
-WHERE active = true;
-```
-
-#### **Connection Pooling Configuration**
-```yaml
-database:
-  host: postgres
-  port: 5432
-  name: kms
-  user: kms_api_service
-  max_open_connections: 25
-  max_idle_connections: 5
-  connection_max_lifetime: 300s
-  connection_max_idle_time: 60s
-```

-
-## Critical Security Vulnerabilities (🔴)
-
-### C-01: Authentication Bypass via Header Manipulation
-**File**: `internal/handlers/auth.go:46`, `internal/middleware/middleware.go`
-**Severity**: Critical
-**CVSS Score**: 9.8
-
-The system relies solely on the `X-User-Email` header for user identification without verification.
-
-```go
-userID := c.GetHeader("X-User-Email")
-if userID == "" {
-    h.logger.Warn("User email not found in headers")
-    // ... returns 401
-}
-```
-
-**Impact**: Attackers can bypass authentication by setting arbitrary `X-User-Email` headers.
-**Recommendation**: Implement proper JWT/OAuth2 token validation or header signature verification.
-
-### C-02: Hardcoded Production Secrets
-**File**: `internal/config/config.go:110,117,163`
-**Severity**: Critical
-
-Default production secrets are hardcoded:
-- JWT Secret: `"bootstrap-jwt-secret-change-in-production"`
-- HMAC Key: `"bootstrap-hmac-key-change-in-production"`
-
-**Impact**: Production deployments using default secrets are completely compromised.
-**Recommendation**: Force secret generation on startup if defaults are detected.
-
-### C-03: SQL Injection Vulnerability in Dynamic Queries
-**File**: `internal/repository/postgres/application_repository.go:281-285`
-**Severity**: Critical
-
-Dynamic query construction without proper parameterization:
-```go
-query := fmt.Sprintf(`
-    UPDATE applications 
-    SET %s
-    WHERE app_id = $%d
-`, strings.Join(setParts, ", "), argIndex)
-```
-
-**Impact**: Potential SQL injection through crafted update requests.
-**Recommendation**: Use proper parameterized queries for all dynamic SQL.
-
-### C-04: JWT Token Stored in URL Parameters
-**File**: `internal/handlers/auth.go:72-73`
-**Severity**: Critical
-
-JWT tokens are passed via URL query parameters:
-```go
-response := domain.LoginResponse{
-    RedirectURL: req.RedirectURI + "?token=" + token,
-}
-```
-
-**Impact**: Tokens exposed in server logs, browser history, and referrer headers.
-**Recommendation**: Use POST requests or secure cookie-based token delivery.
-
-### C-05: Weak Token Generation Fallback
-**File**: `internal/auth/jwt.go:275-277`
-**Severity**: Critical
-
-Fallback to predictable timestamp-based token IDs:
-```go
-if _, err := rand.Read(bytes); err != nil {
-    return fmt.Sprintf("jti_%d", time.Now().UnixNano())
-}
-```
-
-**Impact**: Predictable token IDs enable token enumeration attacks.
-**Recommendation**: Fail securely - abort token generation if crypto/rand fails.
-
-### C-06: Information Disclosure in Error Messages
-**File**: Multiple files including `internal/handlers/*.go`
-**Severity**: Critical
-
-Database and system errors are exposed to clients:
-```go
-c.JSON(http.StatusBadRequest, gin.H{
-    "error":   "Bad Request",
-    "message": "Invalid request body: " + err.Error(),
-})
-```
-
-**Impact**: Internal system information leaked to attackers.
-**Recommendation**: Log detailed errors internally, return generic messages to clients.
-
-### C-07: No Rate Limiting on Authentication Endpoints
-**File**: Authentication handlers lack rate limiting
-**Severity**: Critical
-
-Authentication endpoints are not protected by rate limiting, enabling brute force attacks.
-
-**Impact**: Unlimited authentication attempts possible.
-**Recommendation**: Implement strict rate limiting on `/api/login` and `/api/verify`.
-
-### C-08: Missing CSRF Protection
-**File**: All API handlers
-**Severity**: Critical
-
-No CSRF token validation on state-changing operations.
-
-**Impact**: Cross-site request forgery attacks possible.
-**Recommendation**: Implement CSRF protection for all POST/PUT/DELETE requests.
-
-### C-09: Insecure Password Storage (bcrypt with default cost)
-**File**: `internal/crypto/token.go:73`
-**Severity**: Critical
-
-Using bcrypt with default cost (10) which is insufficient for 2025:
-```go
-hash, err := bcrypt.GenerateFromPassword([]byte(token), bcrypt.DefaultCost)
-```
-
-**Impact**: Tokens vulnerable to offline brute force attacks.
-**Recommendation**: Use minimum cost of 14 for bcrypt in 2025.
-
-### C-10: Lack of Input Validation on Critical Fields
-**File**: `internal/handlers/application.go`, `internal/handlers/token.go`
-**Severity**: Critical
-
-No validation on critical fields like app_id, permissions, callback URLs.
-
-**Impact**: Injection attacks, malicious redirects, privilege escalation.
-**Recommendation**: Implement comprehensive input validation.
-
-### C-11: Missing Authorization Checks
-**File**: `internal/handlers/application.go:164` (delete)
-**Severity**: Critical
-
-No verification that users can only access/modify their own resources.
-
-**Impact**: Users can modify/delete other users' applications and tokens.
-**Recommendation**: Implement resource ownership validation.
-
-### C-12: Timing Attack Vulnerability
-**File**: `internal/crypto/token.go:82-84`
-**Severity**: Critical
-
-Non-constant time token comparison:
-```go
-func (tg *TokenGenerator) VerifyToken(token, hash string) bool {
-    err := bcrypt.CompareHashAndPassword([]byte(hash), []byte(token))
-    return err == nil
-}
-```
-
-**Impact**: Token hashes vulnerable to timing attacks.
-**Recommendation**: bcrypt.CompareHashAndPassword is already constant-time, but error handling should be consistent.
-
-### C-13: Database Connection String in Logs
-**File**: `internal/config/config.go:271`
-**Severity**: Critical
-
-Database passwords logged in connection strings:
-```go
-func (c *Config) GetDatabaseDSN() string {
-    return fmt.Sprintf("host=%s port=%d user=%s password=%s dbname=%s sslmode=%s",
-        // ... includes password
-    )
-}
-```
-
-**Impact**: Database credentials exposed in logs.
-**Recommendation**: Mask passwords in connection strings used for logging.
-
-### C-14: Insufficient Session Security
-**File**: `internal/domain/session.go`
-**Severity**: Critical
-
-Sessions lack proper security attributes:
-- No secure cookie flags
-- No SameSite protection
-- No proper session invalidation
-
-**Impact**: Session hijacking via XSS or network interception.
-**Recommendation**: Implement secure session management.
-
-### C-15: JWT Secret Exposed in Token Info
-**File**: `internal/auth/jwt.go:282-300`
-**Severity**: Critical
-
-Token debugging function may expose sensitive information:
-```go
-func (j *JWTManager) GetTokenInfo(tokenString string) map[string]interface{} {
-    // Returns all claims without filtering
-}
-```
-
-**Impact**: Internal system information disclosure.
-**Recommendation**: Filter sensitive fields in debugging output.
-
-### C-16: Cache Poisoning Vulnerability
-**File**: `internal/cache/cache.go`
-**Severity**: Critical
-
-No validation of cached data integrity.
-
-**Impact**: Attackers could poison cache with malicious data.
-**Recommendation**: Implement cache entry validation and integrity checks.
-
-### C-17: Unrestricted File Upload (Docker Volumes)
-**File**: `docker-compose.yml:74`
-**Severity**: Critical
-
-Docker volumes mounted without proper restrictions:
-```yaml
-volumes:
-  - ./migrations:/app/migrations:ro,Z
-```
-
-**Impact**: Potential container escape if migrations directory is writable.
-**Recommendation**: Ensure proper file permissions and use read-only mounts.
-

-## Incomplete/Dead Code Analysis
-
-### TODO Items Found
-- `internal/auth/permissions.go:296`: "TODO: In a real implementation, this would:"
-  - Incomplete permission evaluation system
-  - Hardcoded test permissions instead of database-driven
-
-### Debug Code in Production
-Multiple debug endpoints and verbose logging enabled in production configuration.
-
-### Unused Security Features
-- SAML authentication implemented but not properly configured
-- OAuth2 providers implemented but not fully integrated
-- Redis caching available but disabled by default
-
-### Missing Components
-- Rate limiting implementation incomplete

-
-2. **DAST (Dynamic Application Security Testing)**
-   - OWASP ZAP scanning
-   - SQL injection testing
-   - Authentication bypass testing
-   - Rate limiting validation
-
-3. **Container Security**
-   - Scan Docker images for vulnerabilities
-   - Validate container configurations
-   - Check for privilege escalation
-
-### Manual Security Testing
-1. **Penetration Testing**
-   - Authentication mechanisms
-   - Authorization bypass attempts
-   - Input validation testing
-   - Session management testing
-
-2. **Code Review**
-   - Security-focused code reviews
-   - Architecture security assessment
-   - Threat modeling exercises
-
----
-
-## Compliance Considerations
-
-### Standards Alignment
-- **OWASP Top 10 2021**: Multiple vulnerabilities identified
-- **NIST Cybersecurity Framework**: Gaps in Identify, Protect, and Detect functions
-- **ISO 27001**: Missing security controls and procedures
-
-### Regulatory Compliance
-- **GDPR**: Missing data protection controls
-- **SOC 2**: Insufficient security controls for Trust Services Criteria
-- **PCI DSS**: Not applicable but good security practices missing
-
----
-
-## Conclusion
-
-The KMS system shows architectural understanding but has critical security vulnerabilities that must be addressed immediately. The authentication system is particularly vulnerable and requires complete redesign. Input validation, error handling, and secure configuration management need significant improvement.
-
-**Overall Security Rating: HIGH RISK** ⚠️
-
-Immediate action is required to address the critical vulnerabilities before any production deployment. A comprehensive security remediation plan should be implemented with regular security assessments.

+if err != nil {
+    log.Fatal(err)
+}
+
+for _, exec := range response.Executions {

+for _, exec := range response.Executions {
+    log.Printf("Running: %s (Function: %s)", exec.ID, exec.FunctionID)
+}
+```
+
+## Types
+
+The client provides comprehensive type definitions that match the FaaS API:
+
+- `FunctionDefinition` - Complete function metadata
+- `FunctionExecution` - Execution details and results
+- `RuntimeType` - Supported runtimes (NodeJS18, Python39, Go120, Custom)
+- `ExecutionStatus` - Execution states (Pending, Running, Completed, Failed, etc.)
+- `Owner` - Ownership information
+- Request/Response types for all operations
+
+## Error Handling
+
+The client provides detailed error messages that include HTTP status codes and response bodies:
+
+```go
+function, err := client.GetFunction(ctx, nonExistentID)
+if err != nil {
+    // Error will include status code and details
+    log.Printf("Error: %v", err) // "get function failed with status 404: Function not found"
+}
+```
+
+## Architecture Benefits
+
+This client package is designed as a lightweight, standalone library that:
+
+- **No heavy dependencies**: Only requires `google/uuid` 
+- **Zero coupling**: Doesn't import the entire FaaS service
+- **Modular**: Can be used by any service in your monolith
+- **Type-safe**: Comprehensive Go types for all API operations
+- **Flexible auth**: Supports multiple authentication methods

+# Skybridge FaaS Implementation Guide
+
+This document explains the implementation of the Function-as-a-Service (FaaS) component in Skybridge, specifically focusing on the Docker runtime implementation that replaced the original mock implementation.
+
+## Overview
+
+The Skybridge FaaS platform allows users to deploy and execute functions in isolated containers. The implementation consists of several key components:
+
+1. **Function Management**: CRUD operations for function definitions
+2. **Execution Engine**: Runtime backend for executing functions
+3. **Repository Layer**: Data persistence for functions and executions
+4. **Services Layer**: Business logic implementation
+5. **API Layer**: RESTful interface for managing functions
+
+## Docker Runtime Implementation
+
+The original implementation contained a mock Docker runtime (`faas/internal/runtime/docker/simple.go`) that didn't actually interact with Docker. The new implementation provides real container execution capabilities.
+
+### Key Features Implemented
+
+1. **Real Docker Client Integration**: Uses the official Docker client library to communicate with the Docker daemon
+2. **Container Lifecycle Management**: Creates, starts, waits for, and cleans up containers
+3. **Image Management**: Pulls images when they don't exist locally
+4. **Resource Limiting**: Applies memory limits to containers
+5. **Input/Output Handling**: Passes input to functions and captures output
+6. **Logging**: Retrieves container logs for debugging
+7. **Health Checks**: Verifies Docker daemon connectivity
+
+### Implementation Details
+
+#### Container Creation
+
+The `createContainer` method creates a Docker container with the following configuration:
+
+- **Environment Variables**: Function environment variables plus input data
+- **Resource Limits**: Memory limits based on function configuration
+- **Attached Streams**: STDOUT and STDERR for log capture
+
+#### Function Execution Flow
+
+1. **Container Creation**: Creates a container from the function's Docker image
+2. **Container Start**: Starts the container execution
+3. **Wait for Completion**: Waits for the container to finish execution
+4. **Result Collection**: Gathers output, logs, and execution metadata
+5. **Cleanup**: Removes the container to free resources
+
+#### Error Handling
+
+The implementation includes comprehensive error handling:
+
+- **Connection Errors**: Handles Docker daemon connectivity issues
+- **Container Errors**: Manages container creation and execution failures
+- **Resource Errors**: Handles resource constraint violations
+- **Graceful Cleanup**: Ensures containers are cleaned up even on failures
+
+## Testing
+
+### Unit Tests
+
+Unit tests are located in `faas/test/integration/` and cover:
+
+- Docker runtime health checks
+- Container creation and execution
+- Error conditions
+
+### Example Function
+
+An example "Hello World" function is provided in `faas/examples/hello-world/` to demonstrate:
+
+- Function structure and implementation
+- Docker image creation
+- Local testing
+- Deployment to Skybridge FaaS
+
+## Deployment
+
+### Prerequisites
+
+1. Docker daemon running and accessible
+2. Docker socket mounted to the FaaS service container (as shown in `docker-compose.yml`)
+3. Required permissions to access Docker
+
+### Configuration
+
+The FaaS service reads configuration from environment variables:
+
+- `FAAS_DEFAULT_RUNTIME`: Should be set to "docker"
+- Docker socket path: Typically `/var/run/docker.sock`
+
+## Security Considerations
+
+The current implementation has basic security features:
+
+- **Container Isolation**: Functions run in isolated containers
+- **Resource Limits**: Prevents resource exhaustion
+- **Image Verification**: Only pulls trusted images
+
+For production use, consider implementing:
+
+- Container user restrictions
+- Network isolation
+- Enhanced logging and monitoring
+- Authentication and authorization for Docker operations
+
+## Performance Optimizations
+
+Potential performance improvements include:
+
+- **Image Caching**: Pre-pull commonly used images
+- **Container Pooling**: Maintain a pool of ready containers
+- **Parallel Execution**: Optimize concurrent function execution
+- **Resource Monitoring**: Track and optimize resource usage
+
+## Future Enhancements
+
+Planned enhancements include:
+
+1. **Multiple Runtime Support**: Add support for Podman and other container runtimes
+2. **Advanced Resource Management**: CPU quotas, disk limits
+3. **Enhanced Monitoring**: Detailed metrics and tracing
+4. **Improved Error Handling**: More granular error reporting
+5. **Security Hardening**: Additional security measures for container execution
+
+## API Usage
+
+The FaaS API provides endpoints for:
+
+- **Function Management**: Create, read, update, delete functions
+- **Deployment**: Deploy functions to prepare for execution
+- **Execution**: Execute functions synchronously or asynchronously
+- **Monitoring**: View execution status, logs, and metrics
+
+Refer to the API documentation endpoint (`/api/docs`) for detailed information.

+# Hello World Function Example
+
+This is a simple example function that demonstrates how to create and deploy functions in the Skybridge FaaS platform.
+
+## Function Description
+
+The function takes a JSON input with an optional `name` field and returns a greeting message.
+
+### Input Format
+```json
+{
+  "name": "John"
+}
+```
+
+### Output Format
+```json
+{
+  "message": "Hello, John!",
+  "input": {
+    "name": "John"
+  }
+}
+```
+
+## Building the Function
+
+To build the function as a Docker image:
+
+```bash
+docker build -t hello-world-function .
+```
+
+## Testing the Function Locally
+
+To test the function locally:
+
+```bash
+# Test with a name
+docker run -e FUNCTION_INPUT='{"name": "Alice"}' hello-world-function
+
+# Test without a name (defaults to "World")
+docker run hello-world-function
+```
+
+## Deploying to Skybridge FaaS
+
+Once you have the Skybridge FaaS platform running, you can deploy this function using the API:
+
+1. Create the function:
+```bash
+curl -X POST http://localhost:8083/api/functions \
+  -H "Content-Type: application/json" \
+  -H "X-User-Email: test@example.com" \
+  -d '{
+    "name": "hello-world",
+    "image": "hello-world-function",
+    "runtime": "custom",
+    "memory": 128,
+    "timeout": "30s"
+  }'
+```
+
+2. Deploy the function:
+```bash
+curl -X POST http://localhost:8083/api/functions/{function-id}/deploy \
+  -H "X-User-Email: test@example.com"
+```
+
+3. Execute the function:
+```bash
+curl -X POST http://localhost:8083/api/functions/{function-id}/execute \
+  -H "Content-Type: application/json" \
+  -H "X-User-Email: test@example.com" \
+  -d '{"input": {"name": "Bob"}}'

-# KMS Frontend - Key Management System
-
-A modern React frontend for the Key Management System (KMS) API, built with TypeScript and Ant Design.
-
-## Features
-
-- **Dashboard**: System overview with health status and statistics
-- **Application Management**: Create, view, edit, and delete applications
-- **Token Management**: Create and manage static tokens with permissions
-- **User Management**: Handle user authentication and token operations
-- **Audit Logging**: Monitor system activities and security events
-- **Responsive Design**: Mobile-friendly interface with Ant Design components
-
-## Technology Stack
-
-- **React 18** with TypeScript
-- **Ant Design** for UI components
-- **Axios** for API communication
-- **React Router** for navigation
-- **Day.js** for date handling
-
-## Getting Started
-
-### Prerequisites
-
-- Node.js (v14 or higher)
-- npm or yarn
-- KMS API server running on `http://localhost:8080`
-
-### Installation
-
-1. Clone the repository:
-```bash
-git clone <repository-url>
-cd kms-frontend
-```
-
-2. Install dependencies:
-```bash
-npm install
-```
-
-3. Configure environment variables:
-```bash
-cp .env.example .env
-```
-
-Edit `.env` to match your API configuration:
-```
-REACT_APP_API_URL=http://localhost:8080
-REACT_APP_APP_NAME=KMS Frontend
-REACT_APP_VERSION=1.0.0
-```
-
-4. Start the development server:
-```bash
-npm start
-```
-
-The application will be available at `http://localhost:3000`.
-

-└── index.tsx          # Application entry point
-```
-
-## API Integration
-
-The frontend integrates with the KMS API and supports:
-
-- **Health Checks**: Monitor API availability
-- **Application CRUD**: Full application lifecycle management
-- **Token Operations**: Create, verify, and manage tokens
-- **User Authentication**: Login and token renewal flows
-- **Audit Trails**: View system activity logs
-
-## Authentication
-
-The application uses a demo authentication system for development:
-
-1. Enter any valid email address on the login screen
-2. The system will simulate authentication and grant permissions
-3. In production, integrate with your identity provider (OAuth2, SAML, etc.)
-
-## Available Scripts
-
-- `npm start` - Start development server
-- `npm run build` - Build for production
-- `npm test` - Run tests
-- `npm run eject` - Eject from Create React App
-
-## Configuration
-
-### Environment Variables
-
-- `REACT_APP_API_URL` - KMS API base URL
-- `REACT_APP_APP_NAME` - Application name
-- `REACT_APP_VERSION` - Application version
-
-### API Configuration
-
-The API service automatically includes the `X-User-Email` header for authentication. Configure your KMS API to accept this header for demo purposes.
-
-## Features Overview
-
-### Dashboard
-- System health monitoring
-- Application and token statistics
-- Quick action shortcuts
-
-### Applications
-- Create new applications with configuration
-- View application details and security settings
-- Edit application properties
-- Delete applications and associated tokens
-
-### Tokens
-- Create static tokens with specific permissions
-- View token details and metadata
-- Verify token validity and permissions
-- Delete tokens when no longer needed
-
-### Users
-- Current user information display
-- Initiate user authentication flows
-- Renew user tokens
-- Authentication method documentation
-
-### Audit Log
-- Comprehensive activity tracking
-- Filter by date, user, action, and status
-- Detailed event information
-- Timeline view of recent activities
-
-## Security Considerations
-
-- All API communications should use HTTPS in production
-- Tokens are displayed only once during creation
-- Sensitive information is masked in the UI
-- Audit logging tracks all user actions
-
-## Development
-
-### Adding New Features
-
-1. Create new components in `src/components/`
-2. Add API methods to `src/services/apiService.ts`
-3. Update routing in `src/App.tsx`
-4. Add navigation items to the sidebar menu
-
-### Styling
-
-The application uses Ant Design's theming system with custom CSS overrides in `App.css`. Follow Ant Design's design principles for consistency.
-
-### Testing
-
-Run the test suite with:
-```bash
-npm test
-```
-
-## Production Deployment
-
-1. Build the application:
-```bash
-npm run build
-```
-
-2. Deploy the `build/` directory to your web server
-3. Configure your web server to serve the React app
-4. Ensure the KMS API is accessible from your production domain
-5. Update environment variables for production
-
