It looks like a game.
It measures like an instrument.

A behavioral sensor the child wants to play.

The Choice · risk under reward

Two gates. The reward just tripled.
What the player does next is the measurement.

We don't ask the child. We watch what they do when the reward rises — the choice itself is the signal.

The Capture

Every choice, every hesitation,
every return — logged.

Session after session, multiplier after multiplier — how much does reward bend behavior? Raw, it's just numbers.
