Reading 808 Claude Code issues looking for one bug shape is the kind of work nobody asks for and everyone benefits from. The thing that hits me reading this: most of the bug shapes that matter aren't in the model. They're in the harness — how tools get called, how state is held, how errors propagate back. The model behaves; the loop around it doesn't.
Curious what your filter ended up being for "this is harness, that's model." That's the line I keep trying to draw.
