"""HTTP adapter for ``GET /projects/{pid}/artifact-index``.

The legacy ``GET /projects/{pid}/artifacts`` array route is unchanged: this
module answers only the new path. ``RouteSpec`` feeds the contract inventory;
the handler is tri-state so the gateway chain continues to its 404 when the
path is not ours.
