# DeleteItem

## Overview

deleteItem permanently removes a DRAFT item from the system. Only items in DRAFT status can be deleted — ACTIVE and INACTIVE items are preserved for audit trails and historical reference. This supports draft cleanup workflows where unwanted items are removed before activation.

## Business Rules

- Target item must exist in the system
- Target item must be in DRAFT status
- ACTIVE and INACTIVE items cannot be deleted — they must be preserved for audit trails
- Deletion is permanent and cannot be undone
- Any taxonomy assignments for the item should be removed before or as part of deletion
