pr list --json and pr view --json now carry source_branch and target_branch; pr view prints both, and every table row gains a target: field. The legacy targetBranch spelling is read as the same fact.
A pull aimed at a feature branch behaves differently when it merges, and until now no listing or view said so. pr create already printed its target; this is the read side catching up, and it applies to PDS, Bobbin and web-sourced rows alike.
