q2 i? When engagement is disabled, the adaptive judge score drops from 4.80 to 3.40, which the authors interpret as the adaptive style controller alone being insufficient to realize persona-conditioned choices in narration. → Md Zabirul Islam 2026

q2 · i? · design · r2

Same five-topic ablation (n=5 topics); the adaptive-dimension judge median falls from 4.80 to 3.40 when the engagement module is disabled. The quoted interpretation is the authors' own; no effect size is printed.

"The adaptive score drops from 4.80 to 3.40 when engagement is disabled. This indicates that the adaptive style controller alone is not sufficient: it specifies persona-conditioned depth, vocabulary, abstraction, and example density, but the engagement generator is the module that realizes those choices in the narration"
