The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

We propose that changing-look AGN transitions arise from variations in the size of the inner ADAF disk.

C2weakest assumption

The size variations of the ADAF are governed by a parameter η, which represents the turbulence strength within the accretion flow and also determines the accretion rate onto the central black hole and controls jet formation and outflow rate.

C3one line summary

Variations in the size of the inner ADAF disk, governed by turbulence strength η, explain changing-look AGN transitions by modulating accretion rate, jet formation, and line-of-sight absorption.
