Type Alias Loader 

pub type Loader<T> = Arc<dyn for<'a> Fn(&'a dyn Executor, &'a mut Vec<T>) -> ExecFuture<'a, Result<(), ExecError>> + Send + Sync>;

The then-load payload, pinned: runs after the rows are mapped, with the caller’s executor and the decoded models, so a second query can be keyed by the first’s keys and its results attached to the rel fields.

Deliberately typed over the model rather than reusing keelson-exec’s row-level ExecLoader: a then-loader’s whole job is to mutate decoded structs (post.rel.user = …), which &[Row] cannot express. ExecLoader remains the payload for row-level extensions; model queries never use it.
