Learn moreHow to contribute
Bug fixes
Open a PR against main. DCO sign-off required (git commit -s). Tests required for anything non-trivial.
New engine adapter
~300 LOC per adapter. Protocol is public + stable. The existing adapters are the reference.
New scheduler adapter
~200 LOC per adapter. Read + lifecycle operations (v1.0), create/update in v1.1.
Documentation
docs live in /docs on the main branch. Markdown. z4j.dev is auto-built from that content.
Triage
Helping new contributors land their first PR, labeling incoming issues, verifying bug reports.
Security
Find a bug, email security@z4j.com, get credit in the advisory. We welcome adversarial reviews.
