Document ID: `pllm.docs.reference.python.pllm.nonlinear`  
Release: `0.1.0`

Nonlinear components identify approximation or protected-evaluation methods separately from their scheduling strategy and executable coverage. 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: [Garbling Gadgets](/research/papers/r03-garbling-gadgets/), [Compact](/research/papers/r18-compact/). 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.nonlinear as nonlinear

methods = [nonlinear.BinaryTableGatedMultiplyQ7(), nonlinear.R03CrtGatedMultiplyQ7()]
assert [method.component for method in methods] == ["pllm/binary-table/v1", "pllm/r03-crt/v1"]
```
