"""Unit coverage for SplitTransport path routing (is_control_plane_path).

Model-management calls (/model/new, /model/delete, /model/info) must go to the
control plane: the data-plane gateway does not serve management routes, so a
misrouted /model/new 404s and takes down every suite that registers deployments
at runtime (llm_translation, batches, access_control). /models must stay on the
data plane; it is the OpenAI-compatible list-models route, not a management
route.
