What changed

MIT, ISC, and the Boost Software License each require that the copyright and permission notice accompany redistributed copies. The incorporated components were correctly named in LICENSE and README.md, but several of the notices themselves were not shipped.

  • THIRD-PARTY-NOTICES.md (new): verbatim notices for liblsl (MIT), asio (BSL 1.0), Catch2 (BSL 1.0), pugixml (MIT), Loguru (public domain), and libsodium (ISC, external dependency, noted for binary distributions). Texts were assembled from the actual files in the tree and from upstream liblsl, not transcribed by hand.
  • liblsl/LICENSE: previously stated only the Secure LSL proprietary terms and asserted they governed "all code in this directory, including both modifications and original components". It now reproduces the original MIT notice (Copyright (C) 2012 Christian A. Kothe) and scopes the proprietary grant to the Secure LSL additions and the integrated work, without purporting to alter the terms under which the upstream code was released.
  • liblsl/thirdparty/asio/LICENSE_1_0.txt (new): asio's source headers say "See accompanying file LICENSE_1_0.txt", but no such file existed in the vendored copy, so the reference was broken.
  • LICENSE: adds a carve-out stating incorporated components remain under their own licenses, and points to the notices file.
  • README.md: links the notices file.

What did not change

The licensing model itself. Academic non-profit use, the commercial license requirement, and the patent position are untouched. This is a notice-compliance and scoping change.

Why it matters beyond compliance

This is a prerequisite for bringing LabRecorder, SigVisualizer, and other client applications into this repository as component directories. With per-component notices preserved and the root carve-out in place, vendoring code that carries its own upstream license no longer places it inside a scope that reads as wholly proprietary.

Note

Wording here is legal-adjacent. Recommend confirming the final text with UCSD OIC before merge.

MIT, ISC, and the Boost Software License require the copyright and
permission notice to accompany redistributed copies. The components
were named in LICENSE and README but several notices were not shipped.

- Add THIRD-PARTY-NOTICES.md with verbatim texts (liblsl MIT, asio BSL,
  Catch2 BSL, pugixml MIT, Loguru, libsodium ISC), assembled from the
  upstream files rather than transcribed
- liblsl/LICENSE stated the proprietary terms over MIT-derived code and
  omitted the upstream notice; it now reproduces the original MIT
  license and scopes the proprietary grant to the additions and the
  integrated work
- asio headers referenced an accompanying LICENSE_1_0.txt that was not
  present; added it
- LICENSE: state that incorporated components remain under their own
  terms and point to the notices file
- README: link the notices file

Wording is legal-adjacent and should be confirmed with UCSD OIC.
