# Prototype

## When to use

- Build a bounded disposable experiment to resolve a specific uncertainty.

**Not for:** implement for production work.

## Steps

1. State one uncertainty, observable criterion and effort bound; choose the simplest runnable form.

2. Implement only what exercises it; label simulated behavior and synthetic data.

3. Run and inspect the experiment against its criterion.

4. Report conclusions in conversation or an approved findings path; retain or remove the prototype according to its actual use.

**Output:** Suggested paths, subject to [human audit](../../../references/human-audit.md): `docs/design/prototype-findings.md` when conclusions need persistence.

## Verify

- The experiment was run and narrows its question; simulated behavior is not presented as real integration.
