1//! Repositories that are archived, deleted or purged, and branches
2//! renamed: what issues, pull requests and runs do about each.
3//!
4//! An archived repository is read-only: its issues and pull requests are
5//! locked and nothing new starts on it. A deleted one looks missing (repos
6//! hides it) and keeps its rows for a restore. A purged one is gone, and
7//! every row kept for it goes with it.
