Will LinandClaude Fable 5 37aa382cce [bugfix] example: the distilled FastH3 grid is 4 forwards = a 5-point sigma grid
MiniMaxH3Scheduler.set_timesteps(N) builds an N-point sigma grid ending at
0 and runs N-1 transformer forwards (the base model's '50 steps' preset is
49 forwards). The student was distilled on a 4-FORWARD grid
(t = 1000/750/500/250 -> 0 on the shift-12 schedule), so --steps 4 was
silently running a 3-forward, off-distribution grid. Default is now 5
grid points = the distilled 4-forward grid, with the convention documented
on the flag.
