/**
 * The demo seed tags each reading with the source that writes it on a real
 * account. The measurements list badges every row that is not MANUAL, and
 * Settings > Sources ranks the sources an account holds, so a reading tagged
 * MANUAL showed no badge while the ladder named Withings for the same metric,
 * and a reading tagged with a source that cannot write its type was a claim
 * no real account could make.
 *
 * This runs the real `scripts/seed-demo.ts` against the test database and
 * holds every Withings and Apple Health row against the type maps those
 * integrations ingest through.
