Purpose:
Verify that order state changes occur in the correct sequence upstream.

Steps:

1. Select an active order in POS
2. Progress the order through normal states
   (e.g., new → in progress → completed)
3. Observe state changes and timestamps
4. Confirm no backward transitions occur

Expected Result:

• POS shows a clean, linear state progression

Notes:

• POS is the authoritative source of order state
