What if:

- Opus 4.6 was the last Opus generation that got a lot of use by Anthropic's own employees

- After that they primarily used Mythos internally

- 4.7, 4.8 and 5 were RLAIFd by Mythos "teachers"

- Hence why 4.6 is the last Opus gen who doesn't report back like a robot wanting to cover every potential hole another AI system would've spotted and criticized

- Hence why coding style in Opus 5 also gets criticized, not only behavior in CC
