Tests are CC0/public domain because there's no reason for them not to be. Examples are also CC0/public domain, but this may be a little bit weird because they are largely straightforward ports of examples from nats.c which carry the Apache license. However, I personally wrote them against the zig bindings and I doubt anyone will end up in a court of law due to their software containing uselessly trivial example code.
