## Language
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119.
C4 is meant to provide a reusable optimal collaboration model for open source software projects. It has these specific goals:
- To maximize the scale and diversity of the community around a project, by reducing the friction for new Contributors and creating a scaled participation model with strong positive feedbacks;
- To relieve dependencies on key individuals by separating different skill sets so that there is a larger pool of competence in any required domain;
- To allow the project to develop faster and more accurately, by increasing the diversity of the decision making process;
- To support the natural life cycle of project versions from experimental through to stable, by allowing safe experimentation, rapid failure, and isolation of stable code;
- To reduce the internal complexity of project repositories, thus making it easier for Contributors to participate and reducing the scope for error;
- To enforce collective ownership of the project, which increases economic incentive to Contributors and reduces the risk of hijack by hostile entities.
- A patch MUST compile cleanly and pass project self-tests on at least the principle target platform.
- A patch commit message SHOULD consist of a single short (less than 50 character) line summarizing the change, optionally followed by a blank line and then a more thorough description.
- A "Correct Patch" is one that satisfies the above requirements.
- Users MUST NOT log feature requests, ideas, or suggestions unrelated to Monero code or Monero's dependency code or Monero's potential/future dependency code or research which successfully implements Monero.
- Users MUST NOT log any solutions to problems (verifiable or hypothetical) of which are not explicitly documented and/or not provable and/or cannot be reasonably proven.
- Thus, the release history of the project MUST be a list of meaningful issues logged and solved.
- To work on an issue, a Contributor MUST fork the project repository and then work on their forked repository.
- To submit a patch, a Contributor MUST create a Platform pull request back to the project.
- A Contributor MUST NOT commit changes directly to the project.
- Maintainers SHOULD NOT merge their own patches except in exceptional cases, such as non-responsiveness from other Maintainers for an extended period (more than 30 days) or unless urgent as defined by the Monero Maintainers Team.
- All Public Contracts SHOULD have space for extensibility and experimentation.
- A patch that modifies a stable Public Contract SHOULD not break existing applications unless there is overriding consensus on the value of doing this.
- A patch that introduces new features to a Public Contract SHOULD do so using new names.
- Old names SHOULD be deprecated in a systematic fashion by marking new names as "experimental" until they are stable, then marking the old names as "deprecated".
- When sufficient time has passed, old deprecated names SHOULD be marked "legacy" and eventually removed.
- Administrators MAY remove Maintainers who are inactive for an extended period of time, or who repeatedly fail to apply this process accurately.
- Administrators SHOULD block or ban "bad actors" who cause stress and pain to others in the project. This should be done after public discussion, with a chance for all parties to speak. A bad actor is someone who repeatedly ignores the rules and culture of the project, who is needlessly argumentative or hostile, or who is offensive, and who is unable to self-correct their behavior when asked to do so by others.
