 ### 1. SQLite Database Path Fix
 
 **File Modified:** `app/services/database_service.py`
 
 **Changes:**
-- Updated default database path from `"legal_documents.db"` to `"/app/data/database.db"`
+- Updated default database path to `/app/data/legal_dashboard.db`
 - Added directory creation with `os.makedirs(os.path.dirname(self.db_path), exist_ok=True)`
 - Added `check_same_thread=False` parameter for better thread safety
 
 **Code Changes:**
 ```python
-def __init__(self, db_path: str = "/app/data/database.db"):
+def __init__(self, db_path: str = "/app/data/legal_dashboard.db"):

-- Ensured cache directory is writable inside container
+- Added directory creation for both `/app/cache` and `/app/data`
+- Set environment variable `TRANSFORMERS_CACHE` to `/app/cache`
+- Ensured directories are created before any imports
