Interface StateChangeWithMeta<V>

Module (definition object) public API.

• Domain factories (Form / CRUD / ...) should return this object.
• .tag is the identity anchor (ModuleTag/Context.Tag), used by $.use(...) and Env injection.
• .impl is the assembly blueprint (ModuleImpl), consumed by React/Runtime entry points.
• .logic() only produces the logic value; .withLogic/withLayer(s) changes the runnable shape (immutable: returns a new object).
