// ersatztv#460: the disable-sync (remove-and-recreate) flows used to stamp the 0001-01-01 MinValue
// sentinel into Library.LastScan. #409 fixed the READ side (the API coerces the sentinel to null and a
// migration cleaned historical rows), so the wire contract was already correct — these tests pin the
// WRITE side for every provider, so no NEW sentinel rows are created. They do not (and cannot) speak to
// rows already written before this change: those keep the sentinel at rest and are covered only by the
// read-boundary coercion, since this ships no second cleanup migration.
