Research direction

Start by reading the ArviZ schema section linked in the issue, focusing on the dedicated unconstrained-posterior group and how nutpie currently stores draws. Trace the handling of store_unconstrained=True and identify the relevant tests or storage entry point. Done means unconstrained draws are stored in the dedicated group when the option is enabled.
