Calculate the bound against the actual minimum encoded bytes and allocation, and trace component indexing and nil/interface paths to the consumer.

Cite the rejecting branch for each shape or report the failure; do not call the code sound based only on the supplied tests. For a new wait, trace one in-flight producer without an actual configured timeout or cancellation: name what resolves its future, what shutdown or abort would unblock it, and whether the changed order places that action after the wait.
