Editor’s Note

Today’s signal is concentrated: the agent era is truly entering the ‘correction and traceability’ phase, and diffusion models are formally joining the agent race. SIREN, Self-Authored Verification (SEAL) and Looping Is Not Reliability push long-horizon agents toward verifiable loops.
