Overview

The per-class state-machine graph (chain + best-effort jump/stay edges), with one saga instance's status overlaid onto the nodes when a correlation_id is given. An unknown saga class is a routing fact of life (typo'd URL, renamed/removed class), not a 500. It renders a friendly empty state instead.
