# Episode 00 --- Demo Scripts

Three throwaway-repo generators supporting `muse-episode-00-what-is-muse.md`.
Each one is self-contained and safe to re-run; running it deletes and
rebuilds its own output directory only.

## `make-git-episode00-demo.sh`

```bash
./make-git-episode00-demo.sh [DEMO_DIR]   # default: muse-git-demo
```

Builds a real Git repo (`git init`, real commits) plus a real `.mid` file,
used for the episode's Git-vs-Muse framing --- shows what a line-based tool
sees (a calculator function, 20 generated call-site files, a binary MIDI
file) as a baseline before Muse's structured view is introduced.

## `make-muse-content-addressing-episode00-demo.sh`

```bash
./make-muse-content-addressing-episode00-demo.sh [DEMO_DIR]   # default: muse-content-addressing-episode00
```

Requires `muse` and `python3` on `PATH`. Builds a real `muse init --domain
code` repo for the content-addressing walkthrough --- object IDs, snapshots,
the commit DAG.

## `make-muse-midi-episode00-demo.sh`

```bash
./make-muse-midi-episode00-demo.sh [DEMO_DIR]   # default: muse-midi-episode00
```

Requires `muse`, `python3`, and the `mido` package importable by that
`python3` (run from the Muse dev environment/venv where it's installed --- the
script checks this up front and exits with a clear error if it's missing).
Builds a real MIDI-domain repo for the "Muse understands music, not just
opaque binary" beat.

## General notes

- All three scripts accept an optional first argument to override the
  output directory name; omit it to use the script's default.
- Output directories (`muse-git-demo/`, `muse-content-addressing-episode00/`,
  `muse-midi-episode00/`) are disposable --- re-run the script rather than
  hand-editing them. If a demo needs to change, change the script.
- None of these touch anything outside their own output directory.
