//! SQL migrations of a service: which files a directory holds, what a
//! history table records, and what is left to apply. Checksums, the
//! history table and the rows written to it are refinery's, so a history
//! refinery began is continued and refinery reads one begun here.
//!
//! Nothing here touches a database; the runners that do share these rules.
