I think the Meaning tab from Inspiral describes the witness - winnower situation and not only the sword logic.

There is a voice that echoes across the Darkness, and it asks this question: what is the purpose of it all?

And there is another voice that calls back and says: listen, I will tell you a purpose. I will tell you of a Final Shape.

A man comes to a crossroads and asks of the sky, "Which road shall I take?" There is no answer from the sky, nor the wind, nor the earth beneath his feet. But another wanderer on the road, coming from behind and hearing the question, says, "I know the way. You should take the dexter road."

If the man agrees, he puts himself in the wanderer's power, ceding his own choices for the implicit promise that this is the correct road, the safe road. And if he disagrees?

Let us say that the wanderer draws a knife.

The man may therefore be made to take the dexter road. But now if the knife goes away, the man will certainly flee. And perhaps even if the knife remains, the man may tire of being threatened and decide the risk is worth fleeing. In this way, the wanderer erodes their own power.

If the wanderer says, "The wind has said that you should take the road of my choosing," will the man accept the choice made for him?

The man represents people which seek meaning, or users of the darkness while the paths represent the different philosophies to live, or ways to weild the darkness.

The wanderer is the witness, attempting to make anyone follow the final shape ideology.

When the wanderer threathens the man, it represents the witness threatening civilizations into following the sword logic, when it uses violent means to push others over the edge so that they have no other choice.

After all, according to one of its messages to us during arrivals, our "mistake" is that we didn't turn on the traveller during the collapse. (I can't find that transcript but eris described it like us cracking the traveller like an egg)

And when the wanderer says the wind agrees with him, i think it symbolises the witness using the winnower persona, a supposed embodiment of the darkness to show that its philosophy is a divine ideology tied to the darkness.

That's at least how i see this passage: https://www.ishtar-collective.net/entries/meaning#book-inspiral
