# Phase 4+ Cleanup - COMPLETE
## Summary
Systematically disabled all remaining MLT/Player/Playlist/Timeline references in mainwindow.cpp that would cause compilation errors due to undefined pointers (m_player, m_playlistDock, m_timelineDock).

## Pattern Applied
All disabled code follows the established convention:
```cpp
// DISABLED: MLT [system]
// Original code commented out
// (void)param; // For unused parameters (to avoid compiler warnings)
```
## Code Quality Notes
- All edits preserve function signatures for forward compatibility
- Unused parameter warnings prevented with (void) statements
- Comments clearly mark disabled sections for future reference
- Non-MLT functionality preserved (e.g., setWindowModified in playlist/multitrack handlers)
## Files Modified
- `src\mainwindow.cpp` - 23 functions systematically disabled
## Compilation Status
✅ Syntax check passed (no diagnostics)
⏳ Full compilation test pending (requires CMake setup)
## Next Steps
1. Complete full cmake/ninja build test
2. Document any remaining linker errors
3. Begin Phase B mail-core implementation:
- IMAP client module
- SMTP client module
- Mail database schema
- Message model/repository
4. Phase B will preserve all infrastructure:
- Settings system
- Database framework
- JobQueue for async operations
- Logging system
- Generic dialogs and UI utilities
