Slot: Reason Ensemble Member Count Is Missing (exposure_model_ensemble_member_count_missing_reason)
Reason exposure_model_ensemble_member_count is null.
Tier: optional
Why this slot matters
Confirms explicitly that a product is single-realisation rather than an ensemble whose member count was dropped. Without it, a null count is ambiguous and the conditionally-core rule for ensemble products cannot be audited.
In plain terms
Many products come from just one model run, so "number of members" genuinely does not apply. This slot says so explicitly, instead of leaving readers to wonder whether information was lost.
