# Capstone Reproducibility

Run:

```
python3 capstone/scripts/run_capstone.py
```

That regenerates every artefact in `capstone/design-table/`,
`capstone/modal/`, `capstone/acoustic/`, and `capstone/figures/`.
Inputs are pure code + material constants in
`capstone/scripts/fujara_design_math.py`. No external data files.

## Environment

- Python: `3.12.x` (system).
- Required packages: `numpy >= 2.0`, `scipy >= 1.17`, `matplotlib >= 3.10`.
- No FEniCS / dolfinx, no `mph` (Comsol), no Wolframscript required.
  See `capstone/capstone-deck.md` Slide 9 for the FEM substitution
  disclosure.

## SHA256 of capstone artefacts (post-run)

Recompute with:

```
find capstone -type f \( -name '*.csv' -o -name '*.png' \) | sort | xargs sha256sum
```

PNG files include matplotlib metadata that can vary across versions; CSV
files are deterministic.
