A delta-query demonstration can explain change tracking, but it does not prove your business integration can recover correctly after an interruption.

A checkpoint says where reading reached. It is not evidence that every downstream business action actually completed successfully as intended.

Define the authoritative source and store processing completion separately from the change cursor, so the two states can be reconciled later.

Test repeated changes, missed updates, and interrupted runs. Verify which behavior the current interface actually supports before relying on it.

Show data freshness to staff and provide recovery for individual items. A working demo should lead to reconciliation questions, not replace them.
