System functional design

SoloDB is organised as Laminas modules with Doctrine entities and repositories, service-layer business logic, controller and route entry points, Twig views, Solr search documents, and route/entity authorisation assertions.

Domain modules own their records and user interface. Cross-cutting modules provide users and permissions, files, mailing, reporting, API resources, deeplinks, configuration options, search, export, and queued processing. See Architecture and Backend module reference for the maintained overview.
