Input: "Package: {{package}}, Framework: {{framework}}, Memory: {{memory}}"
Output: "Package: 0.7.5, Framework: 012, Memory: 003"
```

**CLAUDE.md Template Variables**:
```
✅ {{FRAMEWORK_VERSION}} -> 012
✅ {{MEMORY_VERSION}} -> 003

## Technical Implementation Details

### Version Loading Architecture

**Core Components**:
1. **VersionLoader Class**: Centralized version management
2. **get_package_version()**: Main package version retrieval
3. **get_service_version()**: Service-specific version loading
4. **get_all_versions()**: Complete version registry
5. **SubsystemVersionManager**: Service version tracking

**Key Features**:
- **Caching**: Reduces file system calls
- **Fallback Logic**: Graceful degradation for missing files
- **Path Resolution**: Dynamic framework path detection
- **Error Handling**: Comprehensive error recovery

### Version Source Priority

1. **Package Version**: `package.json` > `VERSION` file > fallback
2. **Service Versions**: `{SERVICE}_VERSION` files > defaults
3. **Template Variables**: Dynamic substitution at runtime
4. **Configuration**: Automatic updates from version source

### File Locations

**Version Files**:
- `/Users/masa/Projects/claude-multiagent-pm/VERSION` (0.7.5)
- `/Users/masa/Projects/claude-multiagent-pm/package.json` (0.7.5)
- `/Users/masa/Projects/claude-multiagent-pm/FRAMEWORK_VERSION` (012)
- `/Users/masa/Projects/claude-multiagent-pm/MEMORY_VERSION` (003)
- `/Users/masa/Projects/claude-multiagent-pm/CLI_VERSION` (006)

**Template Files**:
- `/Users/masa/Projects/claude-multiagent-pm/framework/CLAUDE.md` (uses {{variables}})

**Python Modules**:
- `/Users/masa/Projects/claude-multiagent-pm/claude_pm/__init__.py`
- `/Users/masa/Projects/claude-multiagent-pm/claude_pm/_version.py`
- `/Users/masa/Projects/claude-multiagent-pm/claude_pm/utils/version_loader.py`
