[ \textAttention l = \textsoftmax!\left(\fracQ lK_l^\top\sqrtd_k\right)V_l, \quad l \in \textAct,\textScene,\textDialogue ] To align modalities, the loss encourages matching pairs (text‑image, text‑audio) to have higher cosine similarity than mismatched pairs:
[ R = \lambda_1 \cdot \textCoherence + \lambda_2 \cdot \textNovelty + \lambda_3 \cdot \textEngagement(a,c) ]
[ \mathcalL \textcontra = -\frac1N\sum i=1^N\log\frace^\textsim(z_i^\texttxt,z_i^\textimg)/\tau\sum_j=1^Ne^\textsim(z_i^\texttxt,z_j^\textimg)/\tau ] The ACR module defines a curriculum over story complexity (c) and player agency (a). The reward function (R) combines three terms:
