Developer Centre

The future home for repository links, development setup, standards, testing, releases, and maintainer guidance.

1. Development foundation

  • •Public version control with reviewed changes.
  • •Documented licence and contributor expectations.
  • •Reproducible local builds and automated tests.
  • •Supported compiler, operating-system, and runtime matrix.
  • •Release signing and dependency provenance.

2. Engineering principles

  • •Prefer open protocols and interoperable formats.
  • •Keep security claims testable and narrowly stated.
  • •Separate experimental work from supported releases.
  • •Document compatibility boundaries and migration paths.
  • •Design for maintainability before expanding features.

3. Repository status

The public repository has not yet been announced. Links, setup instructions, issue templates, and contribution rules will appear here when the development foundation is ready.
