Goal
Reattach KDS to the live order feed after idle timeout.

Steps
1) Exit KDS application cleanly.
2) Wait 10 seconds.
3) Relaunch KDS application.
4) Place or observe a test order.
5) Confirm:

• Order appears immediately
• No backlog delay
  6) If issue repeats later → proceed to P-000127-03.

Notes

• This confirms a silent socket/subscribe stall rather than data loss.
