		"notes": "The figure is correct and clean: the number line spans 0→1 (x=100→700), the shaded unmastered mass runs exactly from x=280 (v=0.30) to x=700 (v=1.0), dots sit at the proportional positions 280 and 364, and the single blue arrow shows the +0.16 predict shift. No overlaps, nothing clipped.\n\n**Notes for the teacher:** The figure shows one number line for belief P(mastered), with the light-gray block marking the unmastered mass (1−p) from 0.30 to 1.0, and a single blue arrow from p=0.30 to p⁻=0.44 illustrating that the predict step moves only that unmastered mass by (1−p)×T = 0.16. Dot positions are exactly proportional to 0.30 and 0.44 on the 0–1 axis; the superscript minus in \"p⁻\" is rendered via a tspan for reliable display."
