-- Motion: the library, engagements, artifacts and the append-only score log.
--
-- Hand-written, and it has to be. `motion_templates.origin_artifact_id`
-- references `engagement_artifacts`, and `engagement_artifacts.template_id`
-- references `motion_templates` — the promotion loop is a foreign key cycle,
-- and there is no ordering of two CREATE TABLE statements that satisfies both.
-- Drizzle emits every constraint with the table it belongs to and will not
-- order this for you, so the second half of the cycle is added below as its own
-- ALTER TABLE once both tables exist. Generated output for this schema fails on
-- `relation "engagement_artifacts" does not exist`.
