On real Drupal 12.0-dev the module already installs and the full Unit + Kernel suite is green - what's left is deprecation cleanup.</p> <h3 id="summary-proposed-resolution">Proposed resolution</h3> <p>Land the child issues, then flag the module Drupal 12 compatible</p> <ol> <li><span class="drupalorg-gitlab-issue-link project-issue-status-info project-issue-status-7"><a href="https://www.drupal.org/project/external_entities/issues/3617254" title="Status: Closed (fixed)">#3617254: Enable next-major (Drupal 12) testing in GitLab CI</a></span> - Turn on the next-major (D12) job in GitLab CI (OPT_IN_TEST_NEXT_MAJOR + lenient allow-list for dbxschema) so we actually get D12 results on MRs.
