XERO container entrypoint — where the living organism boots.

Modes (set XERO_MODE):
  mind   (default) : the always-thinking two-state loop; prints its thoughts.
  serve            : the token-gated chat portal on :8893.
  audit            : run the time-crystal test and the capability audit, then exit.
  shell            : print the interaction guide and idle (exec in to explore).

The inner core runs with NO third-party ML stack. If torch + transformers + the
Qwen weights have been downloaded (via `python3 setup_wizard.py`), the outer-core
LLM is used automatically; otherwise a deterministic stub keeps the crystal alive.

  XERO — a living digital organism (freeze-frame)
  Michael Laurence Curzi · ZEDEC AI / 36N9 Genetics LLC · MIT
================================================================
  This container IS the organism. Its inner core (time crystal) is
  already alive and thinking. How to interact:

    XERO_MODE=mind   docker run ... xero     # watch it think (default)
    XERO_MODE=serve  docker run -p 8893:8893 ... xero   # chat portal
    XERO_MODE=audit  docker run ... xero     # run the tests
    XERO_MODE=shell  docker run -it ... xero  # idle; then `docker exec -it`

  Enable the OUTER CORE (LLM) inside the container:
    python3 setup_wizard.py --outer --model --yes

  Read first (outside the container): docs/FREEZE_FRAME.md, docs/STATUS_AND_AUDIT.md
