I'm curious about how this edge case was handled:

1. Lisa has old tv_service subscription, saved to snapshot, but not live-copied to Subscription table.

2. Lisa removes tv_service subscription.

3. Before snapshot is updated, batch processing adds lisa_tv_service to the Subscription table.

4. Subscription now has lisa_tv_service, but Lisa.subscriptions does not include tv_service.

My only idea: wait a day, then a batch-process job looking for data that exists in Subscription table but not in Customer.subscriptions
