experiments_freeze_exposure_create
Freeze exposure on a running experiment while metrics keep flowing. Snapshots the already-exposed users into a static cohort and narrows the linked feature flag so only those users keep matching — new users can no longer enter the experiment. ``end_date`` is left null so long-term metrics (revenue/LTV/renewals/retention) keep accumulating. Enrolled users keep their assigned variant. The serialized status becomes 'exposure_frozen'. Returns 400 if the experiment is not running, exposure is already frozen, the experiment is group-aggregated (group flags cannot be frozen with a person cohort), or the exposed set is too large to snapshot synchronously.

A unique integer value identifying this experiment.
