If they definitely thought you belonged in CLA instead of CSE or CBS they would have offered you that slot by now. Either they don’t see you as a good fit for CLA (highly unlikely given your course rigor and stats) or they are trying to see how you’d fit into one of the more selective colleges you applied to. In this case no news may (still) be good news. I’d be preparing for a “worst case” that includes an invite to CLA and crossing my fingers hard in the meantime . . .
