# Third-Party Notices

The dsviper wheel statically links four third-party components. Their copyright notices and full license texts are reproduced in `THIRD-PARTY-NOTICES.txt`, shipped inside every wheel under `dsviper-<version>.dist-info/licenses/THIRD-PARTY-NOTICES.txt`.

Component | Version | License
--- | --- | ---
ANTLR 4 C++ runtime | 4.12.0 | BSD-3-Clause
Stephan Brumme’s hash-library | — | zlib-style
nlohmann/json | 3.11.2 | MIT
SQLite | 3.47.2 | Public Domain

Each component retains its own copyright. Inclusion in dsviper does not re-license these components — the Digital Substrate Commercial License applies to dsviper itself, not to the embedded third-party code.

The full attribution and license texts are reproduced below, also shipped inside every wheel under `dsviper-<version>.dist-info/licenses/THIRD-PARTY-NOTICES.txt`.

    The dsviper Product incorporates the following third-party components.
    This file reproduces their original copyright notices and license texts
    as required by their respective licenses. The Digital Substrate
    Commercial License (see LICENSE) governs the dsviper Product itself;
    the components below remain under their original licenses.

    4. SQLite — Public Domain
    ================================================================================

    Version: 3.47.2
    Embedded at: third_parties/sqlite/

    The author of SQLite has dedicated the SQLite source code to the public
    domain. From https://www.sqlite.org/copyright.html:

      All of the code and documentation in SQLite has been dedicated to the
      public domain by the authors. All code authors, and representatives of
      the companies they work for, have signed affidavits dedicating their
      contributions to the public domain and originals of those signed
      affidavits are stored in a firesafe at the main offices of Hwaci. All
      contributors are citizens of countries that allow creative works to be
      dedicated into the public domain. Anyone is free to copy, modify,
      publish, use, compile, sell, or distribute the original SQLite code,
      either in source code form or as a compiled binary, for any purpose,
      commercial or non-commercial, and by any means.

    A "blessing" appears in the SQLite source files in lieu of a legal notice:

      May you do good and not evil.
      May you find forgiveness for yourself and forgive others.
      May you share freely, never taking more than you give.
