Materials for "Beyond Prediction Accuracy: Operational Tests for Physical Understanding in World Models"

Materials accompanying the paper "Beyond Prediction Accuracy: Operational Tests for Physical Understanding in World Models" (NeurIPS 2026 Workshop on Physical Understanding for Decision-Making, PhysUnderstand). The archive contains the preregistration (frozen on 20 August 2026), run log and CR0 adjudication of the E2c-CR co-representation campaign, as Japanese originals with English translations; the E2c-CR code; the code, result files and checkpoints that remain from the earlier campaigns of the gate program; and a script that reproduces the reference estimators used in the paper. The raw CR0 measurement files and the E2c-CR checkpoints are not included. README.md describes the contents, the provenance of the records and how to run the code.
