Unsupported system parameter

The generator cannot bind a query parameter or filter to an ECS column, resource or supported execution context. Compilation fails; the last good module keeps running.

#Common causes

• A parameter is not a component, resource, Entity, in Tick, ref Rng or ref Commands in a supported form.
• A fieldless tag component is requested as a column parameter.
• [With<T>] or [Without<T>] names a type that is not a component.

#Fixes

• Use supported query parameters, with ref for component writes and in for reads, and the correct context parameter forms.

• Replace a tag parameter with [With<Tag>]; use [Without<Tag>] to exclude it.

• Make filter types registered components and correct the type named in the diagnostic.
