Community Plan manuals are per USPS state. If you omit ``state``, the catalog sets ``state_required=true`` and ``posted_states``. Commercial participating rows use ``window_kind=deferred_to_agreement`` when the Administrative Guide names the Participation Agreement — ``standard_days`` null is that posted rule, not a missing extract.
