+$app->get('/users/:id', function($req, $res) {
+    $id = $req->param('id');
+    return $res->json(['user' => $userService->find($id)]);
+});
+
+// PSR-7 API (now supported)
+$app->use(function(ServerRequestInterface $request, ResponseInterface $response, $next) {
+    $method = $request->getMethod();
+    $newRequest = $request->withAttribute('processed', true);
+    return $next($newRequest, $response);
+});
+
+// Object pooling configuration
+OptimizedHttpFactory::initialize([

+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Repository Overview
+
+PivotPHP Core is a high-performance PHP microframework inspired by Express.js, designed for building APIs and web applications. Current version: 1.1.0 (High-Performance Edition).
+
+## Essential Commands

+# Run comprehensive validation (includes all checks)
+./scripts/validate_all.sh
+
+# Quality checks
+composer quality:check    # Run all quality checks
+composer phpstan         # Static analysis (Level 9)

+./scripts/pre-commit             # Run pre-commit validations
+./scripts/prepare_release.sh 1.1.0  # Prepare release for version 1.1.0
+./scripts/release.sh            # Create release after preparation
+```
+
+### Running Examples
+```bash
+composer examples:basic        # Basic framework usage
+composer examples:auth        # Authentication example
+composer examples:middleware  # Middleware example
+```
+
+### v1.1.0 High-Performance Features
+```php
+// Enable high-performance mode
+use PivotPHP\Core\Performance\HighPerformanceMode;
+HighPerformanceMode::enable(HighPerformanceMode::PROFILE_HIGH);
+
+// Console commands for monitoring
+php bin/console pool:stats     # Real-time pool monitoring
+```
+
+## Code Architecture
+
+### Core Framework Structure
+- **Service Provider Pattern**: All major components are registered via service providers in `src/Providers/`
+- **PSR Standards**: Strict PSR-7 (HTTP messages), PSR-15 (middleware), PSR-12 (coding style) compliance
+- **Container**: Dependency injection container at the heart of the framework (`src/Core/Container.php`)
+- **Event-Driven**: Event dispatcher with hooks system for extensibility
+
+### Key Components
+1. **Application Core** (`src/Core/Application.php`): Main application class that bootstraps the framework
+   - Version constant: `Application::VERSION`
+   - Middleware aliases mapping for v1.1.0 features
+
+2. **Router** (`src/Routing/Router.php`): High-performance routing with middleware support
+   - Supports regex constraints: `/users/:id<\d+>`
+   - Predefined shortcuts: `slug`, `uuid`, `date`, etc.
+
+3. **Middleware Pipeline** (`src/Middleware/`): PSR-15 compliant middleware system
+   - v1.1.0 additions: LoadShedder, CircuitBreaker
+
+4. **HTTP Layer** (`src/Http/`): PSR-7 hybrid implementation
+   - Express.js style API with PSR-7 compliance
+   - Object pooling via `Psr7Pool` and `OptimizedHttpFactory`
+
+5. **v1.1.0 Performance Components**:
+   - `DynamicPool`: Auto-scaling object pools
+   - `MemoryManager`: Adaptive memory management
+   - `PerformanceMonitor`: Real-time metrics
+   - `DistributedPoolManager`: Multi-instance coordination
+
+### Request/Response Hybrid Design
+The framework uses a hybrid approach for PSR-7 compatibility:
+- `Request` class implements `ServerRequestInterface` while maintaining Express.js methods
+- Legacy `getBody()` renamed to `getBodyAsStdClass()` for backward compatibility
+- PSR-7 objects are lazy-loaded for performance
+
+### Testing Approach
+- Tests organized by domain in `tests/` directory
+- Each major component has its own test suite
+- Integration tests verify component interaction
+- Use PHPUnit assertions and follow existing test patterns
+- v1.1.0 tests in `tests/Integration/V11ComponentsTest.php` and `tests/Stress/`
+
+### Code Style Requirements
+- PHP 8.1+ features are used throughout
+- Strict typing is enforced
+- PHPStan Level 9 must pass
+- PSR-12 coding standard via PHP_CodeSniffer
+- All new code must include proper type declarations
+
+### Performance Considerations
+- Framework optimized for high throughput (2.57M ops/sec for CORS)
+- v1.1.0 achieves 25x faster Request/Response creation with pooling
+- Benchmark any performance-critical changes using `composer benchmark`
+- Avoid unnecessary object creation in hot paths
+- Use lazy loading for optional dependencies
+
+## Development Workflow
+
+1. Before committing, run `./scripts/pre-commit` or `./scripts/validate_all.sh`
+2. All tests must pass before pushing changes
+3. Static analysis must pass at Level 9
+4. Code style must comply with PSR-12
+5. For releases, use `./scripts/prepare_release.sh` followed by `./scripts/release.sh`
+
+## Current Version Status
+
+- **Current Version**: 1.1.0 (High-Performance Edition)
+- **Previous Stable**: 1.0.1 (PSR-7 Hybrid Support)
+- **Tests Status**: 315/332 passing (95% success rate)
+- **New Features**: High-performance mode, dynamic pooling, circuit breaker, load shedding
+
+## Important Notes
+
+- The framework prioritizes performance, security, and developer experience
+- All HTTP components are PSR-7/PSR-15 compliant
+- Service providers are the primary extension mechanism
+- The event system allows for deep customization without modifying core code
+- Documentation updates should be made in the `/docs` directory when adding features
+- v1.1.0 features are opt-in and don't affect default behavior
