Auto stats (piece rates, pool weight vs actual, jigsaw fail rates, distributions) are always compiled — queries below additionally define failstates whose seeds get captured.

Failstate queries

Template inspector — pick an .nbt, click its jigsaw markers

No template loaded.

Pick a structure, add failstate queries (or none for pure stats), set the number of runs and press ▶ Run deep simulation. No 3D rendering happens here — thousands of generations are assembled and analyzed statistically.
