# Bug Fix: tag_manager Import Warning

**Date:** October 6, 2025  
**Issue:** `WARNING: tag_manager not found. Inline formatting will not be preserved.`

## Problem

The `docx_handler.py` module was using an incorrect import statement:
```python
from tag_manager import TagManager
```

This failed because:
1. `tag_manager.py` is in the `modules/` directory
2. `docx_handler.py` is also in the `modules/` directory
3. Relative imports within a package require the `.` prefix

## Solution

Updated the import to use relative imports first, with fallback:

```python
# Import tag manager for inline formatting
try:
    from .tag_manager import TagManager  # Relative import (preferred)
except ImportError:
    try:
        from tag_manager import TagManager  # Absolute fallback
    except ImportError:
        print("WARNING: tag_manager not found. Inline formatting will not be preserved.")
        TagManager = None
```

## Files Modified

1. `modules/docx_handler.py` - Fixed import (lines 19-26)
2. `cat_tool_prototype/docx_handler.py` - Fixed import (lines 19-26)

## Testing

✅ Application starts without warning  
✅ Tag manager successfully imported  
✅ Inline formatting preservation enabled

## Impact

- **Before:** Warning appeared on every startup, inline formatting not preserved
- **After:** Clean startup, full inline formatting support active

This fix ensures that DOCX files with inline formatting (bold, italic, tags) are properly handled during import and export.
