# classified_config_fields

> **Function** in `deepagents_code`

📖 [View in docs](https://reference.langchain.com/python/deepagents-code/_server_config/classified_config_fields)

Classify every `ServerConfig` field for the policy/runtime split.

Every dataclass field must land in exactly one bucket so the fingerprint
split cannot silently drop a setting. A field missing from a bucket is a
programming error and fails closed (raises) rather than being treated as
either policy or runtime by default.

## Signature

```python
classified_config_fields() -> dict[str, str]
```

## Returns

`dict[str, str]`

A mapping of field name to one of `"model"`, `"runtime"`,
