+# acaua-task-test — integration test fixture
+
+**This is not a loadable model.** It exists only to test acaua's task-metadata-routing path.
+
+acaua supports two ways of resolving a model's task:
+
+1. **Metadata read:** `config.json` contains an `acaua_task` field.
+2. **Fallback dict:** `src/acaua/_data/task_fallback.py` maps repo_id to task string.
+
+This fixture exercises path 1. Its `config.json` contains:
+
+```json
+{
+  "acaua_task": "detection",
+  "_note": "Test fixture for acaua's metadata-routing path. Not a loadable model."
+}
+```
+
+Integration test: `tests/integration/test_task_metadata_fixture.py` downloads only this `config.json` (tiny, no weight files), asserts acaua's task-routing dispatches to the detection adapter based on the metadata field.
+
+No weights. No model. No inference.
