STILL returning "Circular dependency detected" even though I commented out the check. This means there must be another place raising this error, or the server hasn't reloaded.

Wait, it's still returning "Circular dependency detected" even though I commented out that check! Let me verify the code file is what I think it is:


grep -n "Circular dependency" /c/Users/MikeSwanson/claude-projects/Autocode-remix/Autocode-fork/backend/app/routers/features.py

Check circular dependency string in file


539:    #         detail="Circular dependency detected"


The only occurrence is commented out. So how is the server still returning this error?
