Slot: offset
Configuration for calculating a value by applying an offset to a baseline value. The baseline value comes from the slot's populated_from field. This is commonly used for longitudinal data where measurements are recorded relative to a baseline. For example, calculating age_at_visit from age + (days * 1/365).
