## 📝 Notes

1. **Accounting Integration**: The accounting post endpoint is ready but needs integration with the actual accounting service. The placeholder code shows the structure needed.

2. **Permissions**: New permissions need to be added to the database:
   - `payroll.runs.print`
   - `payroll.runs.accounting_post`

3. **Department**: Department relationship is now fully integrated and will appear in all payroll responses when loaded.

4. **Period Filter**: The enhanced period filter maintains backward compatibility with existing date range filters while adding convenient month/year options.
