CANONICAL GOOD ENDING: KEEP IT LOST
===================================

You assign the key:

    NODE 19
    STATUS: MAINTENANCE ISOLATION

The severed relay remains severed. Node 19 stays present but silent.
You send only the station identification inward and open a temporary,
one-way field return. No Node 19 hardware crosses with you.

Before leaving, the system asks:

    NODE 19 STATUS?

You enter:

    LOST

The response:

    CONFIRMED
    SYNCHRONIZATION GAP PRESERVED
