+
+## 📋 Summary
+
+**PHASE 4** crée le squelette C++ complet pour RecoverySoftNetz :
+- Build system (CMake)
+- Core recovery engine (interface + stub)
+- File system parser interface
+- Qt6 UI foundation
+- GoogleTest framework setup
+
+---
+

+
+**Total**: ~500 lines of code/config, production-ready structure
+
+---
+
+## 🎯 Key Components
+
+### Build System (CMakeLists.txt)
+```cmake
+- CMake 3.18+ with C++17 standard
+- Qt6 (Core, Gui, Widgets) auto-detected
+- GoogleTest integrated
+- Multi-platform (macOS, Linux, Windows)
+- Separate output directories (bin/, lib/)
+```
+
+### Core Engine (RecoveryEngine)
+```cpp
+class RecoveryEngine {
+  bool StartScan(const std::string& device_path);
+  bool StopScan();
+  int GetProgress() const;
+  int GetRecoveredFileCount() const;
+};
+```
+
+### File System Interface
+```cpp
+class FileSystemInterface {
+  virtual std::string GetFileSystemType() const = 0;
+  virtual bool CanHandle(const std::string& device_path) const = 0;
+  virtual std::vector<FileEntry> Parse(...) = 0;
+  virtual std::pair<int, int> GetRecoveryStats() const = 0;
+};
+```
+
+### UI Foundation (Qt6)
+```cpp
+class MainWindow : public QMainWindow {
+  // Placeholder UI ready for:
+  // - Device selection wizard
+  // - Progress monitoring
+  // - Results display
+};
+```

+## 🔄 Commits (Ready to Push)
+
+```
+3718251 ▪ test(unit): add GoogleTest skeleton and documentation
+e9da137 ▪ feat(fs): add abstract file system parser interface
+afbcc03 ▪ feat(build): add CMake configuration and core recovery engine skeleton
+```
+
+---
+
+## 🚀 Next Steps
+
+### 1. Wait for Bootstrap PR Merge
+- PR from `boz/bootstrap` must merge to `lekesiz/RSN:main` first
+- Then pull bootstrap code into this branch
+
+### 2. Push Phase 4
+```bash
+git push -u origin boz/step-4-cpp-skeleton
+```
+
+### 3. Create PR
+- Base: `lekesiz/RSN:main`
+- Compare: `BOZYILDIZ/RSN:boz/step-4-cpp-skeleton`
+- Title: "Phase 1: C++ core skeleton (CMake, RecoveryEngine, tests)"
+
+### 4. Phase 1 Development Begins
+- Implement NTFS parser
+- Implement APFS parser
+- Implement ext4 parser
+- Add unit tests (>80% coverage)
+- Qt UI improvements
+
+---
+
+## ✅ Build Verification (Post-Merge)
+
+```bash
+cd ~/Desktop/RSN
+mkdir build && cd build
+cmake ..
+cmake --build .
+ctest --output-on-failure
+```

+# 🎯 PHASE 5C — ext4 Parser Skeleton Implementation — COMPLETE
+
+**Date**: 2025-11-03 09:50 GMT+1
+**Branch**: `boz/phase-5c-ext4-parser`
+**Status**: ✅ Ready for merge (production-ready skeleton)
+**Commits**: 4 atomiques (3 impl + 1 doc), prêts pour push
+
+---
+
+## 📋 Summary
+
+**PHASE 5C** crée le squelette ext4 complet pour RecoverySoftNetz :
+- Superblock parsing (magic 0xEF53, offset 1024)
+- Block group descriptors
+- Inode table traversal
+- Directory entry parsing
+- Journal (JBD2) support
+- Deleted file detection
+
+---

+| `ext4_parser.cpp` | 363 L | Implementation (stub) |
+| `ext4_parser_test.cpp` | 422 L | 17 unit tests |
+| Updated `README.md` | +44 L | Documentation |
+
+**Total**: 1,184 lines, production-ready structure
+
+---
+
+## 🎯 Key Components
+
+### Superblock (magic 0xEF53)
+- Offset: 1024 bytes on filesystem
+- Contains: block counts, inode counts, block group info
+- Validation: magic check + feature flag parsing
+
+### Block Groups
+- Organized partitions of filesystem
+- Group descriptors: bitmap locations, inode table pointers
+- Inode bitmap + block bitmap per group
+
+### Inode Table
+- File metadata records (128–256+ bytes each)
+- i_mode: file type + permissions
+- i_dtime: deletion timestamp (0 if active)
+- i_blocks: allocated block count
+
+### Directory Entries
+- Filename → inode mappings
+- Variable-length records
+- UTF-8 filename support
+
+### Journal (JBD2)
+- Transaction log for crash recovery
+- Orphan inode list support
+- Standard ext4 recovery mechanism
