+# Project Analysis
+
+## Architecture Overview
+This is a comprehensive network diagnostics toolkit that provides various network-related utilities. The main entry point is the `SmartNetwork` class which orchestrates all functionality.
+
+Key features:
+- Speed testing via Cloudflare (parallelizable with duration support)
+- Ping operations with statistics
+- Port availability checks (local and remote)
+- Network gateway discovery
+- Public IP retrieval
+- DNS resolution
+- HTTP endpoint health checks
+- Traceroute functionality (with fallback stub)
+
+## Key Components
+
+### SmartNetwork Class
+- Central orchestrator for all network operations
+- Supports caching via `cacheTtl` option for gateway and public IP lookups
+- Plugin architecture for extensibility
+
+### CloudflareSpeed Class
+- Handles internet speed testing using Cloudflare's infrastructure
+- Supports parallel streams and customizable test duration
+- Measures both download and upload speeds using progressive chunk sizes
+- Includes latency measurements (jitter, median, average)
+
+### Error Handling
+- Custom `NetworkError` and `TimeoutError` classes for better error context
+- Error codes follow Node.js conventions (ENOTSUP, EINVAL, ETIMEOUT)
+
+### Logging
+- Global logger interface for consistent logging across the codebase
+- Replaceable logger implementation (defaults to console)
+- Used primarily for error reporting in speed tests
+
+### Statistics Helpers
+- Utility functions for statistical calculations (average, median, quartile, jitter)
+- Used extensively by speed testing and ping operations
+
+## Recent Changes (v4.0.0 - v4.0.1)
+- Added configurable speed test options (parallelStreams, duration)
+- Introduced plugin architecture for runtime extensibility
+- Enhanced error handling with custom error classes
+- Added global logging interface
+- Improved connection management by disabling HTTP connection pooling
+- Fixed memory leaks from listener accumulation
+- Minor formatting fixes for consistency
+
+## Testing
+- Comprehensive test suite covering all major features
+- Tests run on both browser and node environments
+- Uses @push.rocks/tapbundle for testing with expectAsync
+- Performance tests for speed testing functionality
+- Edge case handling for network errors and timeouts
+
+## Technical Details
+- ESM-only package (module type)
+- TypeScript with strict typing
+- Depends on external modules for specific functionality:
+  - @push.rocks/smartping for ICMP operations
+  - public-ip for external IP discovery
+  - systeminformation for network interface details
+  - isopen for remote port checking
+- Uses native Node.js modules for DNS, HTTP/HTTPS, and network operations
+
+## Design Patterns
+- Factory pattern for plugin registration
+- Caching pattern with TTL for expensive operations
+- Promise-based async/await throughout
+- Deferred promises for complex async coordination
+- Error propagation with custom error types
