if i make a little test file like:

```python
# test_read.py
import hashlib
import sys
import pathlib

HASH_BLOCK_SIZE = 1024 * 1024

def inspect_hash(path):
    """"""Calculate the hash of a database, efficiently.""""""
    m = hashlib.sha256()
    with path.open(""rb"") as fp:
        while True:
            data = fp.read(HASH_BLOCK_SIZE)
            if not data:
                break
            m.update(data)

    return m.hexdigest()

inspect_hash(pathlib.Path(sys.argv[1]))
```

then a line in the Dockerfile like

```docker
RUN python test_read.py nlrb.db && echo ""[]"" > /etc/inspect.json
```

just produes a layer of `3B`
