## COMPLETED TASKS ✅

### Strategic Pivot & Analysis
- [x] **COMPLEXITY REALITY CHECK**: Attempted osbuild integration - RESULT: Too complex
- [x] **REVISED APPROACH**: Shifted from osbuild fork to debos backend integration
- [x] **debos CHOICE**: Selected debos over vmdb2 for Debian-native image building
- [x] **CODE ANALYSIS**: Analyzed bootc-image-builder + osbuild relationship
- [x] **debos ANALYSIS**: Identified capabilities (image creation) and limitations (container conversion)
- [x] **INTEGRATION STRATEGY**: Determined hybrid approach using debos for image creation + custom logic for container conversion

### Previous debos Backend (Simplified Approach)
- [x] **Phase 2: debos Backend Integration** ✅ 100% COMPLETE
  - [x] Core debos execution logic (`debos.go`)
  - [x] Higher-level builder interface (`builder.go`)
  - [x] OSTree integration (`ostree.go`)
  - [x] Comprehensive unit tests
  - [x] Demo programs for testing

- [x] **CLI INTEGRATION** ✅ 100% COMPLETE
  - [x] Integrated debos backend into main CLI
  - [x] Automatic backend selection for Debian images
  - [x] Explicit override flags (`--use-debos`, `--use-osbuild`)
  - [x] debos-specific configuration options
  - [x] Maintained CLI compatibility

- [x] **debos Default Backend** ✅ 100% COMPLETE
  - [x] Automatic detection of Debian-based images
  - [x] debos backend selected by default for Debian
  - [x] osbuild backend still available for other distributions
  - [x] Seamless user experience
