aion-server 0.23.0

//! Proofs about what a boot install does to a catalog.
//!
//! The three cases are the whole rule: an empty catalog is claimed, the
//! embedded version already routed is left alone, and a catalog routed
//! somewhere else is NOT re-pointed. The third is the one that matters — it is
//! the property that stops a restart from undoing an operator's rollback, and
//! it is invisible to a test that only ever boots against an empty store.
//!
//! The QUEUE cases sit on top of that rule rather than beside it (#200). A
//! store carried across the assistant's move off `default` is a deferred
//! install of the third kind — and the one an operator must be told about,
//! because the pending cut changes which queue a worker has to serve. So the
//! deferral is proved twice over: that nothing moved, and that the boot said
//! what would move if the operator deploys.
