This package derives in part from the Elastos.NET.Carrier.Native.SDK,
which itself derives from the toxcore project — both also licensed under
GPL-3.0-or-later. The protocol-level parity with those upstreams is
intentional; the wire format implementations in `compat/` reference the
toxcore C source by file:line in their top comments.
