// AC-1 (FT-P-20 URL): outbound POST URL is `/api/annotations/dataset/bulk-status`.
// AC-2 (FT-P-20 body): drift today — production sends `{annotationIds, status}`,
//                      contract wants `{ids, targetStatus: 30}`. `test.fail()`.
// AC-3 (FT-P-21):     UI rows show `Validated` within 2 s of the 200 response.
//
// Requires the suite docker-compose stack with seeded dataset items. The seed
// must include at least 3 items in Created status so the bulk-validate UI
// path is exercised end-to-end.
