Goal
Reset the live feed / handler layer without rebooting the whole machine.

Steps
1) Identify whether KDS is:

• A dedicated KDS device (restart its KDS service/app stack), OR
• A shared store server component feeding multiple screens (restart only KDS-related services).
  2) Restart only the KDS service layer (do NOT reboot everything unless required).
  3) After restart, verify:
• KDS reconnects
• New orders render
• Multiple screens (if present) all repaint correctly
  4) If still failing → proceed to P-000121-05.

Escalation Trigger

• If multiple KDS stations are all stuck after service restart, suspect version mismatch or upstream feed issue.
