We study the moduli stack of degreesemistable-bundles on an irreducible curveof arithmetic genus, whereis a connected reductive group in arbitrary characteristic. Our main result describes a partition of this stack indexed by a certain family of connected reductive subgroupsof(the-pseudo-Levi subgroups), where each stratum is computed in terms of-bundles together with the action of the relative Weyl group. We show that this result is equivalent to a Jordan–Chevalley theorem for such bundles equipped with a framing at a fixed basepoint. In the case wherehas a single cusp (respectively, node), this gives a new proof of the Jordan–Chevalley theorem for the Lie algebra(respectively, algebraic group).
