Rarity Explanation

Strongest signal: Power of two. It appears in 20 supported numbers and contributes +312 after correlation decay.

Why is 16 unusual? Only <0.01% of the 1,000,001 supported numbers receive an equal or higher rarity score. This number falls in the Singular tier. Scoring is grounded in the exact frequency of each detected trait — rarer traits carry more information and contribute more to the score.
