Evidence and limitations

Activity source: protocolbuffers/protobuf via the GitHub API. Counts describe this repository, which may be a mirror or only part of the project.

The 200-commit author sample does not cover the full 90 days. Author counts are lower bounds; concentration describes the sample only.

Few commits can reflect mature software. Commit authors do not establish merge rights, available maintainers, organizational diversity, or knowledge distribution. Funding is unknown; donation links alone do not establish income or runway.
