We are finally getting our fable back. I built a repo that runs two opus 4.8 on the same question in parallel, blind to each other base on the OpenRouter Fusion. Then a third opus reads both and writes the final answer from where they agree, where they split, and what they both missed. One run can be confidently wrong. Two, cross-examined, can't hide it. Put the real fable system prompt on top of the claude.md and the judgment comes back. It sounds like fable again because it's doing what fable did. Link's in the comments.
