Intrinsic DiT activation probes for pre-generation granularity routing
Captured Causal-rCM diffusion-transformer (DiT) activations and probe results for SelfAware-DiT. An intrinsic pre-generation probe on the DiT's own block activations predicts coarse-unsafe temporal segments at AUROC 0.798 (block 11), versus 0.491 for hand-crafted context signals and 0.788 for the external Jev text oracle.
This supports adaptive temporal granularity routing in causal video generation and video world models without an external oracle.
