Knowledge Halo
Domain-conditioned 3D frontier of your vocabulary.
Angle (around the circle) → semantic domain (cluster). Each wedge is one of 24 domains, labels float on the perimeter.
Radius (distance from center) → log frequency rank. Inner = common words you should know; outer = rarer vocab. Rings mark rank 10 / 100 / 500 / 1000 / 2000 / 5000.
Height (vertical) → recall confidence. Mastered words rise, unknowns sit on the floor.
