True north: the system stays fit for a world that keeps changing.
Drive toward an outside sensed early and a future rehearsed, so that change arrives
already accounted for — the system adapting before it is forced to.
You are closer when an external shift was seen and prepared for before it bit;
further when the world moves and the system is caught surprised, or when you chase
signals that never touch it. When your scanning stops connecting to anything the
system could act on, you've wandered into noise — return to: what here must change
because the world did?
The living now belongs to s3; whether to actually change what the system is
belongs to s5.
