Contributing

The repository-level CONTRIBUTING.md is the authoritative contribution checklist. In summary:

• discuss large changes before implementation;
• extend existing verticals and preserve project dependency boundaries;
• add or update MSTest coverage with behavior changes;
• keep default builds and tests deterministic and offline;
• update documentation in the same pull request as public behavior;
• add an ADR for significant architectural choices;
• submit contributions under the repository's Apache License 2.0 terms and preserve third-party notices.
