Classical Limit: Dissipation of Spekkens' Generalised Contextuality under Decoherence
A Spekkens contextual system of odd-dimensional stabilizer plus magic state becomes noncontextual under depolarizing decoherence past a threshold, with quasiprobability representations differing in how well they detect the shift.

Warring Contextualities -- Provably Classical vs Provably Nonclassical
Kochen-Specker contextuality generalizes nonclassicality while Spekkens' noncontextuality generalizes classicality, reconciling the two as successive stages in a hierarchy of classicality.
