Disjoint-union conjecture for oriented cycles

Let $C_1,\ldots,C_t$ be orientations of undirected cycles, and let $C_1\mathbin{\dot\cup}\cdots\mathbin{\dot\cup}C_t$ be their disjoint union.

Disjoint-union conjecture for oriented cycles. Any disjoint union of orientations of cycles is $\delta^+$-maderian.

This would generalize the known result for disjoint unions of digons and the paper's result for a single oriented cycle; its resolution is not stated in the supplied text.
