Pokrovskiy-type conjecture on covering finite complete hypergraphs by monochromatic Berge-cycles

For s,kNs,k\in\mathbb{N} with k2k\geq 2, let c=c(s,k)Nc=c(s,k)\in\mathbb{N} be a constant independent of nn, and let Kn(k)\mathcal{K}_{n}^{(k)} denote the complete kk-uniform hypergraph on nn vertices. An rr-edge-colouring assigns one of rr colours to every edge, and a tt-tight Berge-cycle is a Berge-cycle in which each tt consecutive core vertices lie in a corresponding hyperedge. Pokrovskiy-type conjecture. For every s,kNs,k\in\mathbb{N} with k2k\geq 2, there is some c=c(s,k)Nc=c(s,k)\in\mathbb{N} such that, for every nNn\in\mathbb{N}, every r=s(k1)r=s(k-1)-edge-colouring of Kn(k)\mathcal{K}_{n}^{(k)} contains a collection of at most ss monochromatic tt-tight Berge-cycles whose cores are disjoint and cover all but cc vertices. This generalises the graph case and is presented as a finite analogue of the paper's infinite covering results; the supplied text gives no resolution.
