Slot: Reason Cohort Size Is Missing (cohort_size_anchored_missing_reason)

Reason cohort_size_anchored is null.

Tier: optional

Why this slot matters

Distinguishes "the cohort size is genuinely unknown" from "the pipeline just did not record it". Without the reason, a null count is uninterpretable and downstream users cannot tell whether to chase the number or accept its absence.

In plain terms

When the head count is missing, this slot says why — for example, the tool could have counted but did not, or counting simply does not apply. An explained blank is far more useful than a silent one.
