This plugin adds WebFinger support to a content management system, enabling user and resource discovery via a standard protocol. It is primarily for site administrators and developers who want their users to be discoverable on the decentralized social web and federated networks.

• User Discovery: Responds to requests at the /.well-known/webfinger endpoint, allowing other services to look up user profiles using an identifier like [email protected]. This is the foundational mechanism for federation.
• Profile Integration: Automatically generates WebFinger data for all users on the site, linking to their author pages and avatars. Administrators can customize identifiers via the user profile editor.
• Site Health Checks: Includes integration with the site's health status tool to verify the WebFinger endpoint is correctly configured and accessible, providing clear guidance for troubleshooting.
• Developer Extensibility: Offers filters like webfinger_data and actions like webfinger_render for developers to customize the JSON response or add support for alternate output formats.
• Protocol Compliance: Implements the current WebFinger standard (JRD format) and requires pretty permalinks to be enabled for the endpoint to function correctly.
