Fix red develop 3d7963e322ae

The merge lane found `develop` red at `3d7963e322ae4534231e72c6c10166189e3c96c7` on its own: no queued PR merges until it is fixed. Failing (tests and gate stages): - `frontend-unit-vitest` - … and 1 more: read them in the gate log, as untrusted output The whole gate log: artifact `11236` on lane task 10769. Make `develop` pass its full gate again. Open a PR as usual: the merge lane merges a PR that fixes some of these and adds no failure even while `develop` is red.

develop's only red was vitest Nodes.test R13b (stale join-wrapper assertion after Task 10754). The same fix already landed via Task 10757 (3b42db9a8); R13b passes there. No PR. Memory: none applied.
