This lets us show an accumulating diff across all patches in a turn. Refer to the docs for TurnDiffTracker for implementation details. There are multiple ways this could have been done and this felt like the right tradeoff between reliability and completeness: *Pros* * It will pick up all changes to files that the model touched including if they prettier or another command that updates them. * It will not pick up changes made by the user or other agents to files it didn't modify. *Cons* * It will pick up changes that the user made to a file that the model also touched * It will not pick up changes to codegen or files that were not modified with apply_patch
