Core modules

QQQ 4.0 release. Final 4.0.0 is available. See QQQ 4.0 for release scope and migration guidance.

The core reactor publishes the following 18 coordinates. Import qqq-bom-pom in dependency management, then add only the modules your application uses. See installation for complete Maven syntax.

Backend modules provide storage-specific action implementations. Middleware modules provide configured HTTP, command-line, event, or other application entry points. Core has its own third-party dependencies; it is not dependency-free.

The sample is outside the root reactor. Material Dashboard 0.41.0 is a separate repository and dependency. S3 support belongs to the filesystem facilities; it is not an additional reactor coordinate. Review the actual backend implementation before assuming support for a storage vendor, operation, query feature, or transaction boundary.
