"""v279 -- QGEO.OBLIG.01: the QGEO.SYM.01 bedrock written as a single precise
constructive-QFT lemma, with a proof-tree completeness check showing exactly ONE
analytic node remains open.  This is the formal write-up of the one human math
obligation; the all-orders reduction step it relies on is now machine-proved in Lean
(FORM.QGEO.04, TfptCarrier/SeamDeckClosure.flat_all_orders_clock).

----------------------------------------------------------------------------------
LEMMA (QGEO.SYM.01, constructive-QFT form).
  Let the seam be Sigma = P^1 \\ mu_4 (the four-punctured sphere) carrying the free
  c=8 reflection-positive (OS) quasi-free boundary state omega_Sigma, with
  Dirichlet-to-Neumann / Calderon operator Lambda_Sigma and one-particle modular
  Hamiltonian H (covariance C = (1+e^H)^{-1}, v258).  Let rho be the carrier order-4
  clock (z -> i z) permuting the four mu_4 marks.

  PREMISE (the one open input, QGEO.SYM.01):
      the raw seam carries the FLAT tau=i pillowcase metric g_flat
      -- the Troyanov-unique constant-curvature representative of the conformal
      class fixed by the order-4 deck (cone angles pi at the 4 marks) --
      so that Lambda_Sigma = sqrt(-Delta_{g_flat}) is a function of the flat
      Laplacian.

  CONCLUSION (then everything downstream is [E]):
      omega_Sigma o rho = omega_Sigma   (equivalently [rho, Lambda_Sigma] = 0):
      the carrier mu_4 clock is a symmetry of the seam STATE, not just the geometry
      -> mark-locality -> the metric-sector inclusion -> E8.
----------------------------------------------------------------------------------

  [E] 1. PROOF-TREE COMPLETENESS.  the reduction from 'free RP seam' to the premise
        is a DAG with exactly ONE un-discharged leaf.  Every other node is closed:
        free RP/OS seam (v155/v175) -> 4 marks forced (v195/v216) -> conformal class
        = pillowcase, order-4 => tau=i (v214/v267) -> flat representative
        Troyanov-unique -> [given flat] [rho,H]=0 to ALL orders (v276, Lean
        FORM.QGEO.04) -> omega o rho = omega (v198/v199/v201/SeamDeckClosure) ->
        mark-locality -> E8.  The single open leaf: 'the raw seam state IS the flat
        g_flat state' (Lambda_Sigma = sqrt(-Delta_{g_flat})).
  [E] 2. THE GEOMETRIC SIDE IS FIXED (not the open part).  the flat-metric DtN
        sqrt(-Delta_{g_flat}) is determined and diagonal in the Fourier-mode basis;
        rho commutes with it (and with any spectral function of it) to all orders --
        machine-proved in Lean (flat_all_orders_clock).  So the obligation is NOT a
        geometric ambiguity but a STATE-IDENTIFICATION: is omega_Sigma the geometric
        flat-metric vacuum?
  [C] 3. TWO PROOF ROUTES for the open leaf (either closes QGEO.SYM.01):
        (i)  RP-STATE UNIQUENESS: the reflection-positive quasi-free state on the
             flat tau=i orbifold with the four pi-cone points is unique (= the
             geometric vacuum), so omega_Sigma = that state by construction;
        (ii) TROYANOV + OS: prescribed cone angles pi fix a UNIQUE flat metric in the
             conformal class (Troyanov), and OS reconstruction selects the geometric
             metric's DtN -- so Lambda_Sigma = sqrt(-Delta_{g_flat}).
  [F] 4. LEAN-BACKED.  the all-orders closure step (premise => commutator to all
        orders) is now a Lean theorem with only the standard axioms
        (propext, Classical.choice, Quot.sound), no sorry: any spectral function of
        the diagonal flat Laplacian commutes with the clock (FORM.QGEO.04).
  [O] 5. RESIDUAL.  exactly one constructive-QFT statement -- the open leaf of (1),
        proved via route (i) or (ii) -- closes QGEO.SYM.01.  Until then it is the one
        honest axiom (the role 'c = const' plays in relativity).  This script does NOT
        close it; it states it precisely and certifies the proof tree around it.

Status: [E] the precise lemma + proof-tree completeness (exactly one open leaf) + the
fixed geometric side; [C] the two proof routes; [F] the all-orders step in Lean;
[O] the one constructive-QFT residual.  The formal obligation write-up; does NOT
close QGEO.SYM.01.  Python (graph completeness over the reduction DAG).
