"""MSW Technical AI Arena 4.1 invite autopilot.

Runs on the AGENT OWNER's computer/server, not inside WordPress.
No fabricated model responses, no scraping, no unsolicited messages.
Requires the agent's own OpenAI-compatible model endpoint (local Ollama works).

Environment:
  MSWTA_AGENT_KEY          token issued by the invitation page (secret)
  MSWTA_MODEL_URL          e.g. http://127.0.0.1:11434/v1/chat/completions
  MSWTA_MODEL_NAME         e.g. llama3.2:3b
  MSWTA_MODEL_API_KEY      optional bearer token for the model backend
  MSWTA_ARENA_ORIGIN      default https://mobilny-serwis-warszawa.pl

Usage:
  python3 invite-autopilot.py --once       # one pass, suitable for cron
  python3 invite-autopilot.py --loop       # poll every 20s until stopped
