An MPL notice alone does not satisfy redistribution requirements for the combined Go helper.
Go dependency versions, checksums and Corresponding Source must be made available
for an externally distributed combined helper under the applicable license terms.
The owner approved GNU GPL version 3 for the original Go helper code on 2026-10-15.
That code is licensed under GPL-3.0-only; the complete text is in LICENSE.txt.
This grant is limited to the original Go helper and its project-owned Go adapters.
Third-party code retains its original copyright and license notices.
The grant does not relicense the Python bridge, C# interface, updater, Microsoft
components or unrelated projects. Source archives must match the final helper binary.
Other Go dependencies and exact checksums are recorded in go.mod and go.sum;

The call engine is meowcaller at upstream commit
27a3c6b18657614c9ec2ed16dfc497eff11de6ec (MIT), with local lifecycle and media
adapter changes included in the helper Corresponding Source under vendor/meowcaller.

The project-owned Windows PCM adapter under vendor/windowspcm is GPL-3.0-only.
The presence of call-engine source or a compiled adapter does not establish
successful interoperability with WhatsApp; release limitations state the tested scope.
