Live Measurement Sandbox

Submit events and watch the posterior update in real-time. Different scaffold contexts produce different evidential weight.

Choose a scaffold context and whether the response was correct. Watch how the weight changes the update magnitude.

What to notice: An unaided correct answer (w=0.95) moves the posterior much more than a hint-assisted one (w=0.42). An answer after direct instruction (w=0.08) barely moves it at all. Same answer — different evidence.
