# Experiment 008 — Catalyst Ecology

Build four-catalyst emitters for three different populations. All catalysts and expeditions are available immediately. After the four choices, each complete build continues through four additional fields.

Run from the repository root:

```bash
./experiments/008_catalyst_ecology/run.sh
```

Then open <http://127.0.0.1:8000>.

Controls:

- Move with `WASD` or the arrow keys.
- Aim with the mouse.
- Hold the left mouse button to fire.
- Choose one catalyst after each of the first four fields.

Play expeditions in any order, replay anything you want, and stop whenever you feel ready. Click **Save JSONL** at the end.

Please play before reading [`hypothesis.md`](hypothesis.md).
