This is an experiment to determine what the wall time of a (minimal) "upload a JSON file describing files changed". We are looking for this to take (low) single digit minutes, because if we use this file (and expand it to become a build plan), it will block almost _all_ other actions, and will likely get longer as we add more complex logic and checks. Here's hoping!
