David decided: Rejected proposed lecture-notes UX state machine for adding unnecessary complexity

When the agent proposed extending the lecture-notes state machine with new states including generating_notes and generating_test, David pushed back directly:

this doesnt sound coherent. what are the current states and why are you adding more? eg what is the difference in preparing and generating? what else have you added? why are you adding generating_notes and generating_test? anything you add to the current production implementation needs to earn its place. adding unnecessary complexity creates bugs. take this philosophy with everything

The pushback was philosophical, not just tactical: David was asserting a general principle about system complexity that the agent should apply across the whole design. He required the agent to justify each new state rather than accepting an expanded model by default.
