Architecture

• Core orchestrator: src/DocumentRepository.php
• Configuration: src/RepositoryConfig.php
• Post type and taxonomies: src/DocumentPostType.php
• Uploads and attachment handling: src/DocumentUploader.php
• REST endpoints: src/RestApiController.php
• Metadata fields and caching: src/DocumentMetadataManager.php
• Admin assets and bootstrapping: src/AdminUIManager.php
• Settings toggle (enable/disable feature): src/Settings.php

Front-end/document behavior (search permalink override, title augmentation, publish after untrash) lives in /bcew-document-repository.php.
