JEV · Decision point

Jev classifies posts with Choice, rates signal, actionability and originality with Score, and assigns Noul labels; local thresholds and noise rules decide whether to fold each post.

Adds scores, labels and adjustable filtering thresholds to the X feed, with reversible folding of posts and their attached media.
