Problem

Given old_records and new_records (each a list of dicts with an 'id' key), return a dict with three sorted lists of ids: 'added' (in new but not old), 'removed' (in old but not new), 'modified' (in both, where any non-id field differs between the matched records). Sort each id list ascending.

Before and after snapshots. The delta is in there.
