Figure 3 — The 1/t reveal schedule & reverse process
Expected mask fraction
Mask fraction = (t-1)/T, from 1.0 at t=20 down to 0 at t=0.
P(reveal at step t) = 1/t  ·  ~2 tokens/step
Live generation trace
t = 20 — fully masked 0 / 42

Left: mask fraction decreases by 1/T per step — exact inverse of the forward schedule. Right: 42 positions means ~2 tokens reveal per step even at t=20, so the grid is visibly active throughout. Green tokens are newly revealed; history only logs steps where something changed.
