Implement the server application module (ADR-048) with:
- FastAPI application factory (app.py) exposing the A2A JSON-RPC 2.0
endpoint as the sole client-facing interface. Routes: POST /a2a
(JSON-RPC dispatch), GET /.well-known/agent.json (Agent Card), and
GET /health (container orchestration).
- RemoteGraph adapter (remote_graph.py) for invoking actor graphs
via LangGraph Platform. Each actor graph deploys as a separate
RemoteGraph enabling independent scaling. Includes health tracking,
invocation counting, and a RemoteGraphRegistry for managing
multiple graph deployments.
- Database configuration (database.py) supporting PostgreSQL for
production and SQLite for development. Config-driven via
CLEVERAGENTS_DATABASE_URL and CLEVERAGENTS_SERVER_ENV environment
variables with validated Pydantic settings model.
- Docker deployment (docker/Dockerfile + docker-compose.yml) with
multi-stage build, non-root user, health checks, and PostgreSQL
service.
- FastAPI dependency added to pyproject.toml.
- 26 Behave BDD scenarios covering app factory, A2A dispatch, Agent
Card, health endpoint, RemoteGraph config/adapter/registry, and
database configuration.
- 10 Robot Framework integration tests with helper script verifying
end-to-end server functionality.
