Goal
Catch cases where KDS silently ignores updates due to payload mismatch.

Steps
1) Confirm KDS app version/build and compare against store server / KDS feed version.
2) If any KDS station is on a different version than others, align versions.
3) If a recent update was applied:

• Roll forward (update lagging KDS stations), or
• Roll back (if the new payload broke older clients), depending on your standard.
  4) Retest with a known-new order.
  5) If still failing after version alignment:
• Treat as upstream feed/log issue and escalate with logs + timestamps.

Artifacts to Capture for Escalation

• Time of last order shown on KDS
• Time of newest order missing
• KDS version/build
• Whether clock/animations were updating during the failure
• Whether all stations failed or only one
