Collision physics without the upper-right
A 3.67M-parameter transformer trained after rejecting every 24-frame world containing a player–puck collision in the upper-right arena quadrant.

| Metric | Value | Notes |
|---|---|---|
| Unseen quadrant | 1.257 px | upper-right collisions |
| Matched control | 1.247 px | same upper-right worlds |
| Holdout penalty | +0.8% | nearly complete transfer |
| Training cost | $1.72 | H100 + CPU + memory |
Collision physics transfers almost perfectly across space. The held-out model reaches 1.257 px puck error on upper-right impacts, versus 1.247 px for the matched all-location control: a difference of just 0.8%.
