Model Card
Single 2D vector per player. Five-player lineup vectors are summed, passed through a tanh nonlinearity, then interacted against the opponent lineup vector to predict segment margin. The displayed player rating is that player's neutral-context projection onto the learned scoring head, with the vector coordinates stored in metadata.
Validation visuals are only wired today for the shared team-model bakeoff path. This page still shows output coverage and site placement for this model.
