I think he likely means "code that is hand-reviewed" and not directly controlled by the agent. He's probably meaning to differentiate it against the in-process agent writing the code. It doesn't matter too much if that fixed code was written by an LLM under guidance and review of the SWE, outside the agent.

Ahh ok - that's fair enough - hand-reviewed/not controlled by the agent seems a sensible approach (wasn't sure if it was instructive of a complete distrust of AI generated code)

Agreed, “literally written by hand” didn’t cross my mind. Not by keyboard or pen.
