Trivium: Temporal Regret as a First-Class Objective for Causal-Memory Controllers

In three linesTrivium proposes optimizing three regret objectives for agentic systems: outcome regret, epistemic regret, and temporal regret. Temporal regret captures how long miscalibrated causal models persist. On CausalBench-Seq, Trivium achieves O(log E) temporal regret versus linear growth for outcome-only baselines.
