Then rw [h4] at h3 — h4 : ((1−s)/2).re = (1−s.re)/2 — rewrites the LHS of h3: h3 : (1−s.re)/2 = −↑m — then `exact h3` — but hre's GOAL is `((1 - s) / 2).re = -(m : ℝ)` — h3 has the rewritten form (1−s.re)/2 — NOT the goal form! The rw [h4] at h3 changed h3's LHS away from the goal form. Fix: don't rw at h3 — instead convert the GOAL: \n```\nhave hre : ((1 - s) / 2).re = -(m : ℝ) := by\n  have h4 : ((1 - s) / 2).re = (1 - s.re) / 2 := by simp [Complex.div_re]\n  rw [h4]\n  have h3 := congrArg Complex.re h2\n  rw [Complex.neg_re, Complex.natCast_re] at h3\n  rw [h4] at h3\n  exact h3\n```\nhmm — but the error shows h4 = `simp [Complex.div_re]` produced `(1 - s.re) / 2 = ...`?? The error: `h3 has type (1 - s.re) / 2 = -↑m but expected ((1 - s) / 2).re = -↑m` — so after my rw [h4] at h3, h3 became (1−s.re)/2-form, and exact h3 against goal ((1−s)/2).re-form fails. Restructure per above: rw [h4] at the GOAL first, then exact h3 (already in (1−s.re)/2-form).\n\nWait — actually hold on: `simp [Complex.div_re]` for h4 : ((1 − s) / 2).re = (1 − s.re) / 2 — did simp prove it? If simp produced something odd... the error message is about the EXACT h3 mismatch — so h4 exists. Restructure: rw [h4] at the goal THEN exact h3.\n\nHmm — but actually ((1−s)/2).re vs (1−s.re)/2 — also relevant for hpos etc. Let me fix hG1's hre block by reordering.\n\n3.
