and is it possible to query against the orchestrators database from a separate app?

Hi <@U012EUUT2KT> - for your first question, the answer is no; you could manually put `a` into a state and then it wouldn’t be evaluated, but we don’t support running only parts of a flow.

For the second, yes - we expose a full GraphQL API (<https://docs.prefect.io/orchestration/concepts/api.html#graphql|here are docs>) and if you check out the <https://docs.prefect.io/orchestration/ui/interactive-api.html|Interactive API> in the UI, you can issue commands against it in a nice test environment.
