from every calculated output.

The exact query, encoded request URL, HTTP headers, timestamp, and checksum are in
`data/raw/download_metadata.json`.

## Layout

- `data/raw/`: unmodified NASA response and download metadata
- `data/derived/`: calculated full table, top rankings, tie audit, run summary
- `figures/`: generated PNG figures
- `docs/full_report.md`: results, methods, and limitations
- `code/analyze_rankings.py`: standalone analysis
- `requirements.txt`: Python dependencies

## Run

```sh
python -m pip install -r requirements.txt
python code/analyze_rankings.py
```

Running the script never modifies the raw download.
