 The fixture speaks the production Verse-catalog contract; a deployment smoke
 against the full Odin daemon remains a separate infrastructure gate.

+The `odin` fixture defaults to this sample's Verse, but its `--verse-id`,
+`--verse-name`, `--authority-runtime-id`, `--transport-version`, and
+`--rules-hash` arguments can advertise another real provider during a product
+route-rotation witness. The provider endpoint remains data owned by Odin; the
+consumer still connects only by stable Verse and provider identity.
