The prompt +below carries none of the heuristic scorer's reasoning/technical/code keywords and +stays short, so heuristic scoring lands it in SIMPLE (openai), but an LLM classifier +reads it as a decision that has to weigh tradeoffs and lands it above SIMPLE +(anthropic). The served deployment is read back from the spend log's `model`, so +anthropic proves the classifier ran and openai proves it silently fell back - the +exact failure before the fix.
