STSD →
One connected structure that yields two T-spin Doubles. Often recognized through a three-by-three empty region with J/L construction. It is a distinct geometry from Fractal, not a name for any two consecutive TSDs.
T-spin Triple →
A recognized T-spin clearing three rows. Its deep slot needs a suitable overhang and rotation entry; building a tall T-shaped hole alone does not ensure the T can get inside.
