Johnson Spectrum

If the sequence bends, where does the bend live?

Fixed-size draws live on a mathematical slice, not in an ordinary grid. This spectrum separates single-ball imbalance, pair structure left after singles, and structure needing whole draws.

The maths, in plain language

Harmonics on fixed-size subsets

A $k$ -of- $N$ draw is a vertex of the Johnson graph: two vertices are close when their sets overlap. Degree 1 measures centred single-ball indicators. Degree 2 starts with pair indicators and removes the part already explained by their two single-ball coordinates. The all-degree band uses an overlap kernel.

Fresh fair histories calibrate all three statistics. If $p_1,p_2,p_\ast$ are their raw Monte Carlo p-values, each displayed adjusted value is .

The story behind it

A prism for pattern claims

“Something is unusual” is not yet an explanation. A heavy first band points toward marginal ball frequencies. A heavy second band says some pairing remains after those margins are removed. A kernel-only signal suggests structure that neither summary captures alone.

The separation makes follow-up work narrower and more falsifiable. It does not make an unusual band predictive.
