  The Blanchet link homology theory is an oriented model of Khovanov homology,
functorial over the integers with respect to link cobordisms. We formulate a
stable homotopy refinement of the Blanchet theory, based on a comparison of the
Blanchet and Khovanov chain complexes associated to link diagrams. The
construction of the stable homotopy type relies on the signed Burnside category
approach of Sarkar-Scaduto-Stoffregen.
