# Simulations

Runnable implementations of the models in `models/`. Each simulation names the
model version it implements.

| Directory | Model | Entry points |
|-----------|-------|--------------|
| `gadm02/` | GADM-0.2 (`models/GADM-0.2.md`) | `run_scenarios.py`, `sensitivity.py`, `gsa.py`, `test_gadm02.py` |
| `gadm02/gadm03.py` | GADM-0.3: power channels, wealth (`models/GADM-0.3.md`) | `power_channels.py`, `wealth.py`, `organism_grid.py`, `test_gadm03.py` |

Python 3.10+, standard library only. Use `python3 -B` after quick edits: a stale
bytecode cache can mask same-size changes made within the same second.

```bash
python3 -m unittest discover -s simulations/gadm02      # tests
cd simulations/gadm02 && python3 run_scenarios.py       # → results/summary.md + CSVs
cd simulations/gadm02 && python3 sensitivity.py         # → results/sensitivity.md
cd simulations/gadm02 && python3 gsa.py                 # → results/gsa.md (~5 min; --quick)
```

Results under `results/` are committed so that model documents can cite them.
Regenerate them after any change to the model or the scenarios.
