# Prototype

A playable build that validates whether the core loop is fun. Disposable by design — do not expect prototype code to survive into production.

## Content Guide

- **Playable build** — installable and runnable without the dev team present
- **Playtest notes** — accumulated across sessions, linked from this artifact
- **Fun verdict** — explicit pass/fail on whether the loop landed

## Completion

Complete when a prototype build is playable end-to-end by a new player and playtest data supports a confident "fun / not fun" verdict.

## Quality Signals

- Multiple playtest sessions with non-team players
- Fun verdict is supported by specific observations, not vibes
- The prototype exists in a state where another player can install and play it
