use gts_macros::struct_to_gts_schema;

/// GTS base type schema for Resource Group types.
///
/// Defines the `x-gts-traits-schema` contract: `can_be_root`,
/// `allowed_parent_types`, `allowed_membership_types`.
///
/// "Is this type a tenant?" is **not** a trait — it is derived from the type
/// code: any type whose GTS chain starts with [`TENANT_RG_TYPE_PATH`] is a
/// tenant type.
///
/// All chained RG types (tenant, department, branch, etc.) inherit from this
/// base contract via `allOf` + `$ref`.
///
/// # TODO: replace manual DTOs when `gts-macros` supports `x-gts-traits-schema`
///
/// Currently `gts-macros` (`struct_to_gts_schema`) does not generate
/// `x-gts-traits-schema` in the output JSON Schema. Once it does, this struct
/// should replace:
/// - `models::ResourceGroupType` (response DTO)
/// - `models::CreateTypeRequest` (create request DTO)
/// - `models::UpdateTypeRequest` (update request DTO)
///
/// Blockers: `gts-macros` needs camelCase serde support, `x-gts-traits-schema`
/// generation, `metadata_schema` field support, and `Clone`/`Debug`/`Default`
/// derives.
///
/// # Schema ID
///
/// ```text
/// gts.cf.core.rg.type.v1~

/// prefix is the single source of truth.
///

/// `can_be_root: true` so root tenants are valid placements.
