Diagnosis for the linked job only: run 29965852605, job 89077771006, unity-testsuite, attempt 1. The failure happened before Unity playmode tests produced results. game-ci/unity-test-runner@v4 launched unityci/editor:ubuntu-2022.3.32f1-linux-il2cpp-3, Unity connected to the licensing client, then reported License is not active (com.unity.editor.headless) / No valid Unity Editor license found. The cleanup path then also logged Seat id does not belong to user while returning entitlement license. Root cause looks like Unity license/seat activation state for the runner/container, not a SpacetimeDB test failure.
