1//! The world installed when nothing has been pushed, and the marker that says which database it
2//! belongs to.
3//!
4//! Built from the same fixtures the seed writes its database rows from: the restore-from-template
5//! setup path runs no seed, and a world of the mock's own there would hand the two setup paths
6//! different fixtures.
