WHAT THIS PROJECT MEASURES
README
Crafter compresses open-world survival into a reproducible research environment with semantically meaningful achievements. It is inexpensive enough for frequent evaluation while still testing visual agency.
Trunchbull needs an immutable game image, pixel observations, an action adapter, seeded resets, achievement rewards, and replay capture before it can publish comparable results.
EXECUTION CONTRACT
Requires a visual sandbox with seeded resets, image observations, discrete actions, and achievement scoring.
