Proposed SafeGraphAgent-RAN

Appendix / extended temporal baselines

Scientific wording note

Dataset/source summary

Prediction plots

+

The main benchmark focuses on time-aware tabular, residual, graph-agentic, and safe-control models. Older temporal baselines are moved to the appendix because they underperform in the current dataset and should not drive the main scientific claim.

+

Pseudo-label action metrics are not sufficient to prove real control quality. Control quality is assessed through offline reward, slice-specific KPIs, action-switch behavior, safe fallback rate, and safety-constraint behavior.
