# Distribution Compliance

This page records the release boundary for public Monata packages. It is a
maintainer checklist, not legal advice.

## Public Packages

Public releases publish only Monata-owned Python packages:

- `monata`
- `monata-techlib`

Do not publish this repository's internal circuit-tool packages, simulator
binaries, or locally built native toolchain artifacts as part of the public
Monata release.

## External Simulator Boundary

The `monata` package may include backend adapters for external tools, but it
must not vendor those tools.

Allowed in `monata`:

- Python code that renders ngspice-compatible netlists.
- The default `ngspice-subprocess` backend, which executes a user-installed
  `ngspice` executable.
- The `ngspice-shared` backend, which loads a user-installed `libngspice`
  shared library at runtime through Monata's default Python FFI dependency.

Not allowed in `monata` public wheels or sdists:

- `ngspice` executables.
- `libngspice.so`, `libngspice.dylib`, or `ngspice.dll`.
- XSPICE `.cm` code-model binaries.
- OpenVAF, Xyce, XDM, ADMS, or other native toolchain binaries.
- PDK files, foundry decks, PTM model-card bundles, or compiled `.osdi`
  model binaries.

Documentation may explain how users can install or build external tools from
upstream sources in their own environment. Those instructions must preserve the
tool as a user-installed runtime dependency rather than a Monata-distributed
asset.

## Monata Techlib Boundary

`monata-techlib` intentionally carries optional technology-library assets.
The package has a mixed content boundary:

- Monata-authored Python loader code, entry points, tests, and techlib metadata
  are MIT licensed.
- PTM model cards are redistributed third-party model data. Preserve PTM
  attribution and no-warranty notices.
- The bundled BSIM-CMG Verilog-A source subset is third-party source under
  ECL-2.0. Preserve the upstream `LICENSE.txt`.
- Precompiled `.osdi` files are not shipped. OSDI artifacts are local cache
  outputs created only when the user enables compilation and provides OpenVAF.

The package metadata must include `LICENSE`, `NOTICE`, and the bundled
BSIM-CMG `LICENSE.txt` in `license-files`.

## Release Checks

Before publishing, inspect the built distributions:

```bash
python -m build
twine check dist/*
python -m zipfile -l dist/*.whl
tar -tf dist/*.tar.gz
```

For `monata`, confirm that the wheel contains no simulator, model compiler,
PDK, PTM, or compiled model artifacts.

For `monata-techlib`, confirm that the wheel contains the intended PTM and
BSIM-CMG source/model files, the declared license/notice files, and no
simulator/compiler binaries or `.osdi` outputs.

If a release needs to include a new third-party asset, update `NOTICE`,
package metadata, tests, and this page before publishing.
