Slot: Metric Temporal Aggregation Rule (metric_temporal_aggregation_rule)

For heat-wave flags, how multi-day exposures are stamped on individual days (e.g. first_day_of_event / each_day_of_event / last_day_of_event).

Tier: recommended

Why this slot matters

Stamping a five-day event only on its first day versus on every day changes which person-days count as exposed, directly altering effect estimates in daily time-series and case-crossover designs.

In plain terms

A heat wave spans several days but health records are kept day by day; this says which calendar days actually get the "heat wave" label — just the first day, every day, or the last.
