Role In The Wiki
Time-HD should be used when evaluating whether a model handles many aligned numeric channels and cross-channel dependencies. It should not be treated as evidence for action-conditioned world modeling because it is a passive forecasting benchmark.

At the entity level, Time-HD should be used when evaluating whether a model handles many aligned numeric channels and cross-channel dependencies. It should not be treated as evidence for action-conditioned world modeling because it is a passive forecasting benchmark. This page should stay as the object card; source pages carry slot-level verdicts, evidence, and missing pieces.
