# Fetch an archived orchestration version

> Returns the exact graph a given version describes.

Returns the exact graph a given version describes. Every run records the version it started on in `orchestration_version` and executes that graph for its whole life, so this is how you read the topology a run actually took — including a run whose orchestration has been rewired since.
