A policy team is reviewing operator permissions for a new Claude deployment on an adult fiction platform. The platform wants to enable Claude to write sexually explicit content between adult characters. According to the Constitutional AI operator permission model, what is the correct characterization of this permission?

B is correct because Claude's behavior model distinguishes between default behaviors, non-default behaviors that operators can enable, and absolute restrictions. Sexually explicit content between adults is a documented example of a non-default behavior that operators may enable for appropriate platforms (adult content sites, romance fiction platforms) through their system prompt, subject to Anthropic's operator agreement which requires age verification and other platform controls. A is wrong because explicit adult content is not an absolute restriction — it is a non-default behavior with operator-gated enablement. The absolute restrictions are things like CSAM, CBRN synthesis, and content designed to facilitate real-world violence. C is wrong because users cannot enable non-default behaviors that operators have not already enabled; the permission hierarchy is Anthropic > Operator > User, and users cannot grant themselves permissions above the operator ceiling. D is wrong because explicit sexual content is not a default behavior; Claude's defaults are conservative, and this content type requires explicit operator enablement.
