"""Part A, first half — on controller v0.267.0 (the field's version): vikunja installed, seeded (A),
backed up by the product (the update's own `backing-up` leg, then a pull that fails: nothing moves),
RESTORED from its own unit — which recreates its volumes WITHOUT compose labels (R-658) — and seeded
again (B, after the restore). Evidence only; every act is a product endpoint."""
