"""Fixtures: real Treasury documents, from the shapes that differ.

The auction query is one JSON document a hundred and twenty fields wide, and
the fields do not all start at the same time: bidder categories, the
competitive breakdown and the result artifact that states the release minute
all begin in 2008. The fixtures here are a handful of rows from that query --
one auction from before 2008 and several from after it -- and the small XML
artifacts that go with them.

The rate feeds are fixed for a single year each. That is enough, because the
thing that changes between years is which columns exist, and the fixtures
include a year with a 20-year point and one without.
