# `assist`: The Assist Seam (opt-in, degrade-only LM suggestions)

```{py:currentmodule} myform.assist
```

The deterministic degradation path always runs and always produces a result; an `Assist` can only
*improve* a lowering the rules flagged as a judgment call. `NullAssist` is the default and the only
path when assists are disabled -- that mode makes zero network attempts. The gateway-backed assist
posts tiny schema-constrained prompts to the local OpenAI-compatible gateway and memoizes results
on disk by node content hash.

`get_assist` is the one seam callers need: it resolves `enabled`/config precedence and returns
either `NullAssist` (disabled), `GatewayAssist` (enabled without caching), or `CachedAssist`
wrapping a gateway (enabled with caching), importing network-facing modules only when enabled.
