What does this research mean for the field?

A single 8-bit decision token can forecast continuous embeddings via a linear reader, anticipate state changes using a simple transition model, fuse complementary modalities at the posterior level, and provide greater adversarial robustness than full-feature models. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

To establish the predictive capabilities and limitations of an 8-bit class-discriminant decision token across continuous forecasting, state anticipation, and multi-sensor fusion.
Evaluated five pre-registered experimental protocols using real-world public datasets covering industrial degradation, robotics, and clinical electrocardiography.
Tested forecasting architectures including vector autoregression (VAR) and logarithmic spirals, token-transition anticipation models, and single-token posterior fusion strategies.
Benchmarked trustworthiness via adversarial perturbation distances to Voronoi decision boundaries and calibration evaluation using expected calibration error (ECE) before and after temperature scaling.
Continuous embedding forecasting using linear VAR achieved skill vs. persistence up to +0.30 at 12 steps across three of four streams, whereas spiral models proved redundant and unstable.
State-change anticipation reached an AUC of 0.972 on industrial turbofan run-to-failure with a correlation of -0.64 against remaining useful life, though sudden-onset events yielded lower performance (AUC ~0.65).
Posterior-level sensor fusion improved macro-AUC by +0.033 on 12-lead ECG and +0.035 on robot force-torque data (bootstrap CIs excluding zero), while providing a 1.25x to 1.9x higher adversarial robustness ratio compared to full-feature models.
