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

The WAs in NGC 3783 have undergone significant structural and dynamical evolution over the past 24 years.

C2weakest assumption

That the eight absorption components identified in 2024 data correspond to physically comparable structures in the 2000-2001 epoch and that differences arise from real changes rather than variations in data quality, calibration, or unaccounted modeling degeneracies between components.

C3one line summary

New 2024 observations of NGC 3783 show the warm absorbers have 1.5 times higher total column density, with structural changes including a tripling in the dominant component, indicating significant evolution over 24 years.
