/**
 * @file Tests for the persisted run history (`server/lib/dashboard-runs.js`).
 * A run's id is its tmux pane name, which every Start in that pane reuses, so
 * a new run must ARCHIVE the previous row under its own id instead of
 * overwriting it; and a row is flagged dead only when its tmux session is
 * really gone — panes outlive a server restart.
