## 🔥 CRITICAL BLOCKERS (Fix First - 1 Hour Total)

### Blocker #1: Fix `src/atoms_mcp/__init__.py` (15 min)
**Current Problem**:
```python
from .core.mcp_server import AtomsServer  # ← BROKEN - core doesn't exist
```

**Solution**:
```python
"""Atoms MCP Server with Hexagonal Architecture"""
__version__ = "2.0.0"
__all__ = []
```

**Impact**: Unblocks ALL imports

---

### Blocker #2: Delete `src/atoms_mcp/core/` (30 min)
**Problem**: Old code directory conflicts with new architecture

**Solution**:
```bash
rm -rf src/atoms_mcp/core/
```

**Impact**: Removes conflicting implementations

---

### Blocker #3: Clean Up Old Files (15 min)
**Delete these files** (no longer needed):
- `atoms_cli.py`
- `atoms_cli_enhanced.py`
- `atoms_server.py`
- `atoms` (script)
- `config/` directory
- `settings/` directory

**Impact**: Removes duplication, cleans repo

rm -rf src/atoms_mcp/core/

# 3. Delete old files (15 min)
rm -f atoms_cli.py atoms_cli_enhanced.py atoms_server.py atoms
rm -rf config/ settings/

# 4. Test imports (1 hour)
python3 << 'PYTHON'
import sys
sys.path.insert(0, 'src')
from atoms_mcp.domain.models import Entity
from atoms_mcp.application.commands import CreateEntityCommand
from atoms_mcp.infrastructure.config import get_settings

## 🔧 COMMON ISSUES & FIXES

### Issue: ImportError after fixing __init__
**Cause**: Python path not set
**Fix**:
```bash
export PYTHONPATH="${PYTHONPATH}:$(pwd)/src"
```

### Issue: Tests fail with "ModuleNotFoundError"
**Cause**: Import issues in conftest
**Fix**: Run `pytest tests/unit_refactor/conftest.py --collect-only` to see errors

### Issue: "Cannot import X from Y"
**Cause**: Missing export in __init__.py
**Fix**: Check the layer's __init__.py has `__all__` defined

### Issue: Circular import error
**Cause**: Layer importing from above layer
**Fix**: Check dependency direction (domain → app → adapters)
