This is a short human-readable description of the current step in this specific Image object's own finite-state-machine workflow, kept as a flattened summary directly on the Image object. Unlike the Downloader's FSM, which tracks a network transfer, this Image-level FSM tracks what UCS Manager is doing with the file itself once it has already arrived, for instance extracting it from a bundle or validating its checksum, and this field gives an admin a plain-text look at that specific step. While a newly arrived bundle is being unpacked into its individual component images, this might read something like 'Extracting image' until each component file is confirmed present.
