Content on an A/B test variant cannot be changed here. The 400 names
update_ab_test_variant so test status and live-change confirmation stay
enforced. When the key also has ab_tests:read, the error includes
abTests[] with every matching test and variant; otherwise those protected
identifiers are omitted. Get Template reports
the same collection on template.abTests before you write.⌘I
