Scores a learner's answer separately from the explanation, detects correct answers supported by incorrect reasoning, and creates a contrastive replay.

A future live path can use GPT-5.6 to classify open-ended reasoning and draft replays; the public demo is explicitly a precomputed, tested fixture.
