MWE-ECL: Recoverable Long-Range Context Does Not Always Override Local Lexical Priors

We test the prediction that a distant discourse anchor can remain explicitly recoverable yet fail to change the locally preferred reading of a familiar multiword expression; such failures should concentrate when the model's no-anchor default conflicts with the anchor, while prior-correct decisions remain larg
