The engine crate carries the spec's nouns as typed state (dimensions,
materials, sources, lots, recipes, facilities, discovery, knowledge,
shipments, markets, carrier and producer policies), validate_catalog as the
generation plan's first gate, and the pipeline fixture as a test-only
constructor proven to be a well-formed state document. The shell is a
binary that refuses to run until there is something to drive. Spec, map,
and doctrine included.
