3//! Generated by metaphor-schema. Do not edit manually.
4//!
5//! Type alias over `GenericCrudService` — all CRUD logic lives in backbone-core.
6//! For custom behaviour, create `issue_service_custom.rs` (preserved on regen).

16/// All 12 standard CRUD operations (list, create, get, update, patch,

21///
22/// ```rust,ignore

25///     // add domain-specific dependencies here
