### **🚀 Phase 2.5.6: Real OSTree Operations (Next Priority)**
**Status**: 🔴 **BLOCKED** - OSTree API complexity and type mismatches discovered
**Investigation Results**:
- **Build Status**: ✅ **COMPILES** - OSTree imports work without glib version conflicts
- **Real Issue**: OSTree Rust API is significantly different from expected:
- No `ostree::Commit` type (only `ostree::ObjectType::Commit`)
- `Repo::open()` requires different parameters than expected
- `resolve_ref()` method doesn't exist (use `resolve_rev` instead)
- `load_commit()` method doesn't exist (use `read_commit` instead)
- `Variant::new_string()` doesn't exist (use different constructor)
- `get_array()` method doesn't exist (use `fixed_array` instead)
**Specific API Challenges**:
1. **Repository Opening**: `Repo::open()` expects `&Repo` and cancellable parameter
2. **Reference Resolution**: Use `resolve_rev()` with different signature
3. **Commit Loading**: Use `read_commit()` with different return type
4. **Variant Creation**: Different constructor methods available
5. **Metadata Access**: Different API for accessing commit metadata
**Next Steps**:
1. **Research Correct OSTree API**: Study actual method signatures and types
2. **Implement Gradual Migration**: Replace one method at a time with correct API
3. **Alternative Approach**: Consider using system commands (ostree CLI) as fallback
4. **Documentation**: Create comprehensive API mapping for future reference
**Dependency Status**:
- ✅ **glib versions**: Both 0.19.9 and 0.20.12 coexist without compilation errors
- ✅ **ostree crate**: Version 0.20.4 available and working
- ✅ **polkit crate**: Version 0.19.0 working with glib 0.19.9
- ⚠️ **API complexity**: Much higher than initially estimated

- **Phase 2.5.1-2.5.4**: ✅ **COMPLETE** - Infrastructure and testutils
- **Phase 2.5.5**: ✅ **COMPLETE** - Real implementation (all development commands complete)
- **Phase 2.5.6**: 🔴 **INVESTIGATED** - Real OSTree operations (API complexity discovered)
**Phase 2.5.6 Investigation Summary**:
- **Dependency Myth Busted**: glib version conflicts don't prevent compilation
- **Real Issue**: OSTree Rust API is significantly more complex than expected
- **Build Status**: ✅ **COMPILES** with OSTree imports
- **API Challenges**: Method signatures, types, and patterns differ from documentation
- **Next Priority**: Research correct OSTree API or implement CLI fallback approach## 🏗️ **Build Dependencies and Environment** 🟡 **IN PROGRESS**
