In the S0-54 tutoring episode, the learner reaches the correct posterior (1/6) yet the three Stage 2 evidence scopes yield different diagnoses, with full trajectory credit withheld because part of the interpretation remains tutor-owned¶

Subclaims¶

q1 i? A trace in which the learner correctly computes 1/6 and applies the reasoning after prevalence changes still receives a mixed diagnosis: the later tutor turn supplies an interpretation the learner should construct, the agency handoff is incomplete, and transfer is not tested before closure. → Zixin Chen 2026

q1 · i? · qualitative · r?

Case-study audit of the Stage 2 episode S0-54 (a statistics learner with a 1% disease prevalence and a 99%-sensitive, 5% false-positive test). The article reports the learner derives 1/6 and explains the base rate matters, while Table 7 shows local tutor quality, trajectory, and learner-change scopes yield different diagnoses; an answer-only check would record success.

"The findings are complementary: within the simulated trace, the learner repairs the inverse-conditional misconception and remains engaged, but a later tutor move supplies an interpretation the learner should construct, leaving the agency handoff partial; the dialogue also closes before changed-surface transfer."
