Module mock 

Offline answers, so the shapes can be learned without an API key.

Deterministic: the same state and question always produce the same numbers. Plausible, not predictive — nothing here reasons about anything.

Functions

answer

Simulate an answer to one question. None for question shapes the simulator cannot fake.

answer_json

One answer as it arrives on the wire — what :last shows offline, and what the cost estimate measures to say what an answer of this shape costs.

body

The body the mock answers would have arrived in — so :last teaches the same shape offline.

models

What :models shows offline.
