Firstly, we elaborate on what we exactly imply by a $\\Lambda$CDM-like evolution or kinematic/cosmographic degeneracy with the $\\Lambda$CDM model, using the lessons from the statefinder diagnostic. Then, we consider two models with interaction in the dark sector: coupled fluid-fluid model and coupled quintessence model. We enforce the \\emph{ki","authors_text":"B.
