Fable specifically refused to harden the security of codebases. If you use misdirection to force Fable to do just that, that's the removal of a guardrail.

Anthropic specifically stated that ANY security requests should be shunted to Opus 4.8. This was bypassable.

I don't see what your confusion here is. Fable was prevented from working on any security tasks. A significant amount of people, myself included, witnessed Fable refusing to harden code as a result. Bypassing that is a bypass of guardrails.

Your assertion that working on security is not working on security because you used misdirection is of course, preposterous.

You wouldn't be making the same claim if Fable refused to work on chemical weapons research but happily proceeded to do so if you claimed it was for eradicating pests.
