Editor’s Note

Today’s signal is highly concentrated: agent ‘reliability and governability’ is replacing ‘is the model strong enough’ as the main contradiction. Research-wise, EFCA, Tree-of-Experience, RADEG and SHE attack the long-horizon ‘can’t stay stable’ problem from four angles: credit assignment, experience trees, execution gating and safety harnesses.
