# Java Rules

## Apply Order

1. start with `rules/common/`
2. layer `rules/java/` for package layout, API, testing, and runtime behavior guidance
3. consult `knowledge-bases/seeded/java/rules/java/` when the seeded pack has deeper framework or review cues

## Focus Areas

- package boundaries, API shape, and build-safe changes
- testing, dependency management, and runtime configuration
- service and library concerns when framework behavior matters
