Struct RuleType 

pub struct RuleType(/* private fields */);

Open subject-dimension vocabulary bound to access_control_rules.rule_type.

Core mints exactly two: RuleType::USER and RuleType::ROLE. Every other dimension (department, cost centre, clearance, …) is an extension concern, minted with RuleType::extension and taught to the resolver via a SubjectDimension registered by register_subject_attribute_provider!. Core never interprets an extension slug.

This mirrors AuthzContext: the column is an open vocabulary validated at the Rust boundary rather than by a SQL CHECK, so an unrecognised-but-well-formed slug is data, not an error.
