Description

Is it possible to make a prompt that updates dynamically based on an asynchronous callback? This seems like it should be doable, but I'm not sure because it looks like the layout code might assume that the prompt is fixed once it is computed. For example, I might want to make a shell prompt that includes the git branch name that automatically updates when the branch is changed, even if it is changed in another terminal window.

Research direction

Start by tracing the layout code and prompt computation to determine whether prompts are fixed after creation and how asynchronous callbacks could trigger updates. Define the expected refresh behavior, including a shell prompt that reflects a git branch changed in another terminal, then verify that the prompt updates without disrupting the active layout.
