Abstract
This study focuses on addressing distributed Byzantine-resilient output containment issues for heterogeneous continuous-time multi-agent systems. Inspired by the digital twin technology which creates a virtual replica of a physical object or system, a virtual layer named twin layer is introduced in this work, which is parallel to the conventional cyber-physical layer. The twin layer is more secure than the cyber-physical layer, which generates the secure reference trajectory of each agent via real-time data processing and simulation. Moreover, it decouples the resilient output containment against Byzantine attacks (BA) into two defense sub-schemes: One on the twin layer against Byzantine edge attacks (sending wrong and different messages to neighbors) and the other on the cyber-physical layer against Byzantine node attacks (falsifying input signals). On the twin layer, we develop a topology-assignable distributed resilient estimator by utilizing a novel secure centroid approach, which enhances the resilience of the twin layer by adding a minimal fraction of trusted edges. It is proved that achieving strong <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex-math notation="LaTeX">$[({n+1})f+1]$</tex-math></inline-formula>-robustness towards the leader set is adequate for ensuring the resilience of the twin layer. On the cyber-physical layer, we design a decentralized adaptive controller against Byzantine node attacks and can also handle potential inter-layered controller faults. This novel adaptive controller has the merit of converging exponentially at an adjustable rate, whose error bound can be explicitly stated. Consequently, we manage to address the resilient containment problem against BAs, in which the agents subject to Byzantine node attacks can also achieve output containment instead of just the normal agents. The simulation examples confirm the efficacy of this newly developed hierarchical protocol, where both normal and Byzantine followers converge within the dynamic convex hull formed by the normal leaders.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
