"""v285 -- QGAMB.ROUTEII.01: Route (ii) (seam-net condensation) decomposed into a
lemma chain, with every dischargeable lemma discharged and the ONE irreducible lemma
isolated -- AND the key result that Route (ii)'s open lemma COINCIDES with Route (i)'s
(v284), confirming the v282 unification at the lemma level.  Executes the external-
review priority "attack Route (ii)": it does NOT prove the open premise, but it shows
the holomorphy side reduces to the SAME single seam lemma as the geometry side.

TARGET (Route (ii)).  The seam-Calderon net has no nontrivial abelian sector,
equivalently |det K| = 1 (the holomorphic side) -- then (E8)_1 and the unique bulk
follow.

The lemma chain, with status:
  M1 [E] no nontrivial abelian sector  <=>  |det K| = 1  <=>  holomorphic (mu-index 1)
        -- v234 (GATE.HOLO.01): #(1-dim irreps) = |Gamma^ab| = |H1(S^3/Gamma)| = 1
        <=> E8; v235 (GATE.HOLO.02): the Chern-Simons det K = 1 form.
  M2 [E] holomorphic c=8  <=>  (E8)_1 (the unique even unimodular rank-8 lattice);
        the c=8 counterexample SO(16)_1 has |det| = 4 -- v277 (QGAMB.TIERB.01) +
        v281 (QGAMB.MODULAR.01: #anyons = |det Gram|, E8 -> 1, SO(16) -> 4).
  M3 [E] the condensation tower D5(+)A3 (det 16) -> D8 (4) -> E8 (1) is the unique
        mu4-Lagrangian glue -- v92 (GATE.METRIC.07, glue uniqueness) + v281 (tower) +
        v235 (anyon condensation).
  M_open [O] the ONE residual: the FREE RP seam actually condenses the full
        mu4-Lagrangian glue, |det K| -> 1 (the free RP seam has no abelian sector).
        v234/v235 identify this exactly as the deck premise QGEO.SYM.01.

  [E] 1. CHAIN DISCHARGED 3/4.  M1,M2,M3 are existing [E] results; only M_open
        remains, and it is QGEO.SYM.01 (the mu4-deck condensation, v234/v235).
  [E] 2. THE DISCRIMINATOR.  |det K| = 1 (E8, holomorphic) vs |det K| = 4 (SO(16),
        non-holomorphic) -- same c=8, so holomorphy is the load-bearing bit; the
        condensation tower 16 -> 4 -> 1 shows the path, M_open is whether the free
        seam traverses it fully.
  [E] 3. ROUTES (i) AND (ii) SHARE ONE OPEN LEMMA.  Route (i)'s L_open ('the raw
        seam is the constant-curvature/geometric flat tau=i state', v284) and Route
        (ii)'s M_open ('the free RP seam condenses the mu4-Lagrangian glue', =
        QGEO.SYM.01) are the SAME lemma -- both say 'the raw seam IS the (E8)_1-at-
        tau=i object' (v282: chi_E8(i)=12, tau=i both the order-4 CM point and the
        (E8)_1 modulus).  So the two routes are two decompositions of ONE open lemma;
        proving EITHER closes BOTH.
  [O] 4. THE UNIFIED OPEN LEMMA (reviewer's exact proof demand).  construct a
        canonical equivalence between the raw seam KMS/DtN state and the holomorphic
        (E8)_1 net at tau=i.  This single statement closes both routes; it is the
        state-identification theory-selection step, still [O].

Status: [E] 3/4 lemmas discharged + the discriminator + the route-(i)/(ii)
coincidence; [O] the unified open lemma (canonical seam<->(E8)_1 equivalence).
Decomposes Route (ii), isolates its single open lemma, and shows it coincides with
Route (i)'s -- confirming v282 at the lemma level.  Does NOT close it.  Python.
