Object-safe metadata access for one dynamic scalar-assignment group.

Implementors are bound to a concrete group at model compilation time. They must not select a group indirectly from thread-local state, a runtime name lookup, or the active phase. Typed Rust groups retain their direct function-pointer metadata and never use this dynamic boundary.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
