"""
FastAPI application for the Meta-Optimizer Environment.
This module creates an HTTP server that exposes the MetaOptimizerEnvironment
over HTTP and WebSocket endpoints, compatible with EnvClient.
Endpoints:
- POST /reset: Reset the environment (optionally with task_id for eval)
- POST /step: Execute an action (lr_scale, momentum_coef, grad_clip_threshold, weight_decay_this_step)
- GET /state: Get current environment state
- GET /schema: Get action/observation schemas
- WS /ws: WebSocket endpoint for persistent sessions
Usage:
# Development (with auto-reload):
uvicorn server.app:app --reload --host 0.0.0.0 --port 8000
# Production:
uvicorn server.app:app --host 0.0.0.0 --port 8000 --workers 4
# Or run directly:
python -m server.app
"""

Entry point for direct execution via uv run or python -m.
This function enables running the server without Docker:
uv run --project . server

Args:
host: Host address to bind to (default: "0.0.0.0")
port: Port number to listen on (default: 8000)
For production deployments, consider using uvicorn directly with
multiple workers:
