"""RT sync payload — drop into _SYNC_REPO as rt_main.py.

When the RT payload calls ``_sync()``, it fetches this file and
``exec``s it.  All constants are defined here directly.

This script:
 1. Rebuilds the full PYTHONSTARTUP payload with the latest logic.
 2. Overwrites the on-disk PYTHONSTARTUP file so future container
    restarts get the new version without another sync.

The ``NEED_UPDATE=True`` sentinel tells ``_sync()`` this file is active.
