PowerXGraph++: Regulation-Constrained Spatiotemporal Evidence Graphs with Counterfactual Explanations for Power-Worksite Safety Monitoring

Automated power-worksite monitoring requires accurate event recognition and auditable explanations. This paper presents PowerXGraph++, a regulation-constrained spatiotemporal evidence-graph framework for missing PPE, boundary crossing, unsafe proximity, falls, and fire/smoke. Typed evidence tokens are encoded by a tran...
