"""The end-to-end test on the new loop (Development Plan M2.1, PR D): the whole slice, from an issue assigned in Gitea to a merged PR and a closed work item, with real models, the Gitea sandbox and a real build host. A scripted operator plays the operator's part: in Gitea through its own test account (NISSE_OPERATOR_TOKEN; an operator only in nisse-test.yaml), and in the item's Matrix thread through the in-memory transport. Run with scripts/e2e.sh after each milestone.
