 # CLAUDE.MD - AI Assistant Development Guide for zapret (MacOS Edition)
 ## 🎯 Project Overview
 **zapret** is a DPI (Deep Packet Inspection) circumvention tool that has been **fully refactored for MacOS** with native support for both **Intel (x86_64)** and **Apple Silicon (ARM64)** architectures.
 ### Core Purpose
 - Bypass DPI-based censorship and network filtering
 - Provide transparent HTTP/HTTPS proxy capabilities
 - Support both Linux and **MacOS (Darwin)** systems
 - Native MacOS integration with PF (Packet Filter) and launchd
 ### Critical Design Principle
 ⚠️ **IMPORTANT**: macOS is **NOT BSD**! While it shares some BSD heritage, it is a unique hybrid system (XNU kernel = Mach + BSD + Apple components). This project correctly treats Darwin as a distinct platform with its own requirements.

 ## 🏗️ Architecture: MacOS Support
 ### Supported Architectures
 1. **x86_64** (Intel Macs)
   - Target: `x86_64-apple-macos<version>`
   - Minimum: macOS 10.8 (Mountain Lion)
   - Recommended: macOS 11.0+ (Big Sur)
 2. **ARM64** (Apple Silicon: M1, M2, M3+)
   - Target: `arm64-apple-macos<version>`
   - Minimum: macOS 11.0 (Big Sur)
   - Native ARM64 optimization
 3. **Universal Binaries**
   - Single binary containing both architectures
   - Automatic selection at runtime
   - Best for distribution
 ### MacOS-Specific Components
 #### Build System (Makefile)
 ```makefile
 # Key variables
 DIRS_MAC := tpws ip2net mdig  # MacOS-compatible components
 MACOS_TARGET                  # Architecture target (auto-detected)
 MACOS_VERSION                 # MacOS version (auto-detected)
 IS_MACOS                      # Darwin detection flag
 ```
 **New Makefile Targets for MacOS:**
 - `make mac` - Build for current architecture (auto-detected)
 - `make mac-universal` - Build universal binary (both architectures)
 - `make mac-auto` - Auto-detect and build
 - `make mac-info` - Display build information
 - `make mac-clean` - Clean MacOS-specific builds
 #### Architecture Detection Script
 **Location:** `scripts/macos_arch_detect.sh`
 **Functions:**
 - `detect` - Detect current architecture
 - `info` - Display system information
 - `check` - Verify build readiness
 - `build` - Build for current architecture
 - `universal` - Build universal binary
 - `version <ver>` - Set MacOS version target
 **Usage:**
 ```bash
 ./scripts/macos_arch_detect.sh detect
 ./scripts/macos_arch_detect.sh info
 ./scripts/macos_arch_detect.sh build
 ./scripts/macos_arch_detect.sh universal
 ```
 #### Testing Script
 **Location:** `scripts/test_macos_arch.sh`
 Performs comprehensive system testing:
 - System information gathering
 - Architecture detection validation
 - Build tools verification
 - Compilation test
 - MacOS-specific feature checks
 ## 🔧 Development Workflow for Claude
 ### When Making Changes
 1. **Architecture Awareness**
   - Always test on both x86_64 and ARM64 if possible
   - Use universal binary builds for distribution
   - Respect architecture-specific optimizations
 2. **MacOS vs BSD vs Linux**
   - **NEVER** assume BSD compatibility
   - **ALWAYS** use Darwin-specific checks
   - **PREFER** MacOS-native APIs and tools
 3. **Build System**
   - Modify component Makefiles in `tpws/`, `ip2net/`, `mdig/`
   - Update main `Makefile` for cross-component changes
   - Test with `make mac` and `make mac-universal`
 4. **Testing Protocol**
   ```bash
   # Step 1: Clean build
   make mac-clean
   # Step 2: Build current architecture
   make mac
   # Step 3: Test functionality
   ./scripts/test_macos_arch.sh
   # Step 4: Build universal binary
   make mac-universal
   # Step 5: Verify installation
   ./install_macos.sh info
   ```

 ## ⚠️ Important Constraints
 ### What NOT to Do
 ❌ **Do NOT treat macOS as BSD**
 - Different system calls
 - Different networking stack
 - Different firewall (PF with Apple modifications)
 - Different service management (launchd, not rc)
 ❌ **Do NOT assume Linux compatibility**
 - No iptables (use PF instead)
 - No systemd (use launchd instead)
 - No /proc filesystem
 - Different socket behavior
 ❌ **Do NOT ignore architecture differences**
 - x86_64 and ARM64 have different optimizations
 - Endianness may differ in edge cases
 - System libraries may vary
 ❌ **Do NOT skip testing**
 - Always run `./scripts/test_macos_arch.sh`
 - Always test both architectures when possible
 - Always verify installation and uninstallation
 ### Security Considerations
 🔒 **System Integrity Protection (SIP)**
 - Some operations require SIP awareness
 - Never instruct users to disable SIP permanently
 - Prefer SIP-compatible solutions
 🔒 **Code Signing**
 - Binaries may need signing for distribution
 - Respect notarization requirements
 - Document signing requirements
 🔒 **Permissions**
 - Use appropriate file ownership (root:wheel)
 - Respect privilege separation
 - Document permission requirements
