[View canonical HTML](https://pllm.run/sdk/reference/python/pllm/protocols-masked-linear/)

Document ID: `pllm.docs.reference.python.pllm.protocols.masked-linear`  
Release: `0.1.0`

Masked-linear records configure the public-weight prepared protocol and its optional trusted-client Freivalds verification contract. Presence documents API availability, not complete model, security, or deployment coverage; check [implementation status](/sdk/reference/status/) before relying on a path.

## Research context

Relevant design inputs: [Slalom](/research/papers/r07-slalom/). PLLM's implementation and evidence claims remain independent.

## Python SDK example

The example performs a bounded offline task and checks an observable result. It does not download a checkpoint or contact a provider.

```python
import pllm.protocols.masked_linear as masked_linear

method = masked_linear.MaskedLinear()
assert method.to_spec() == {"component": "pllm/masked-linear", "params": {}}
```
