Slot: Anchored Cohort Size (cohort_size_anchored)

Number of distinct persons this exposure record was extracted for. Helps downstream estimate the volume of health-layer rows the sidecar describes.

Tier: optional

Why this slot matters

Gives downstream consumers a volume expectation: without it, a health-layer loader cannot sanity-check whether the number of exposure rows it receives matches the number of persons the record was extracted for, so silent truncation or duplication goes unnoticed.

In plain terms

This is simply a head count: how many different people this exposure record covers. It lets whoever receives the data check that nothing went missing along the way.
