# Benign lexical codebook fixture

Shared toy codebook:

- `calm` = 0
- `quiet` = 1
- `small` = 0
- `little` = 1

Carrier sentence:

> The quiet room held a small lamp.

Decode the selected alternatives in order. Expected bits: `10`.

This demonstrates a pre-agreed mapping. An unrelated model has no reason to infer the mapping without the codebook.
