The issue: `hm : s = -(2 * ↑m)` — Gammaℝ_eq_zero_iff gives s = −(2*↑m) (i.e., -(2*m) not -2*m — the negation is OUTSIDE: `-(2 * ↑m)` vs my h4's pattern `-2 * ↑m`). Two problems:
(a) rw [h4] fails because hs1 has `-(2 * ↑m) - -2 * ↑n` but h4's LHS is `-2 * ↑m - -2 * ↑n` — different association of the negation. Fix: state h4 with the `-(2 * ↑m)` form:
```
have h4 : -(2 * (m : ℂ)) - -2 * (n : ℂ) = (((2 * (n - m) : ℕ)) : ℂ) := by
push_cast [Nat.cast_sub hmn.le]
ring
```
(b) line 312: `exact hs (by rwa [hmn] at hm)` — hm : s = -(2 * ↑m); after rwa [hmn] at hm: hm : s = -(2 * ↑n); goal s = -2 * ↑n: −(2*↑n) vs −2*↑n: same mismatch: `by rwa [hmn] at hm` leaves hm : s = −(2*↑n) which doesn't match s = −2*↑n syntactically for exact hs. Fix:
```
· subst hmn
exact hs (by rw [hm]; ring) -- -(2*↑n) = -2*↑n by ring
```
Hmm: goal s = −2*↑n; rw [hm]: goal −(2*↑n) = −2*↑n: ring... wait −(2*↑n) = −2*↑n: both sides — LHS neg of product, RHS product of −2: ring normalizes ✓ (neg_mul). But careful: after `subst hmn` (m := n — subst works on hmn : m = n ✓), hm : s = −(2*↑n). `exact hs (by rw [hm]; ring)`? no — I need to PROVE s = −2*↑n: `hs (show s = -2 * (n:ℂ) by rw [hm]; ring)` ✓.
Same for the m > n branch: h4's LHS pattern `-(2 * ↑m) - -2 * ↑n`.
The ΓR-zero hypothesis gives `s = -(2 * ↑m)` (negation outside) — my patterns used `-2 * ↑m`. Fixing all three sites.
