Contributing

Contributing guidelines:

• Apache 2.0 license; sign-off required (DCO)
• Conventional commits (feat:, fix:, docs:, etc.)
• Run ./tools/pre-push-check.sh before pushing
• Engine changes must keep the architectural firewall intact (no Qt UI deps)
• Tests required for all new features and bug fixes (80%+ coverage in domain layer)

The full contribution guide is in AGENTS.md in the source tree.

Polished contributor docs are part of Phase 2 documentation.
