#!/usr/bin/env python3 """v651 -- QGEO.ORBASM.01: the FULL Z3-ORBIFOLD ASSEMBLY of the seam on the lattice -- the projection sum Z_orb = sum_{sectors} eps * Z[sector] with every admissible phase wiring, the discrete-torsion question settled by machine cohomology, the GSO-like spin wirings built explicitly, and the seam assembly identified against the independent seam data. THE H^2 QUESTION (settled up front, machine-checked in H2): H^2(Z3, U(1)) = 0 -- for cyclic groups the Schur multiplier is trivial: every U(1)-valued 2-cocycle on Z3 is symmetric, so the discrete-torsion phase eps(g,h) = omega(g,h)/omega(h,g) is IDENTICALLY 1, and the three mu3-valued cocycle classes all trivialize over mu9 in U(1). There is NO discrete torsion for a pure Z3 orbifold. The residual U(1)-trivial phase tables omega^{a g h + b h} act as exact CHARGE-CLASS RELABELINGS of the projection (H2.2) -- the real freedom of the assembly sits in the SPIN structure: deck^3 = (-1)^F (v623, exact Z6 trace arithmetic in orbifold_modular_probe.py M4) makes the orbifold a Z6 quotient of the fermionic seam double, and the physical choice is the GSO-like parity wiring per twist sector. CONVENTIONS (inherited read-only from orbifold_modular_probe.py): seam double = one complex free fermion, N-site chain, eps(k) = -cos k, half filling, NS base. The FULL Z6 sector grid: spatial boundary condition psi(x+N) = -e^{i pi gt/3} psi(x), momenta k = 2 pi (m + 1/2 + gt/6)/N (gt = 2g reproduces the Z3 twist g; gt = 3 is the Ramond sector with two exact zero modes for 4 | N); temporal insertion V_ht = exp(i pi ht (Nhat - N/2)/3) (V_2h = U_h of the modular probe; V_3 = (-1)^F for even N/2). Exact free product: Z6[gt,ht] = prod_k 2 cosh((L eps_k - i pi ht/3)/2), real and >= 0 for all 36 sectors (k -> k+pi pairs eps -> -eps; the two R zero modes give (2 cos(pi ht/6))^2 >= 0, exactly 0 at (3,3) -- the R,(-1)^F zero). tau = i L/N. T is the discrete Dehn twist (translation by N sites): per mode e^{i k N} = e^{i pi (3+gt)/3} uniformly, so EXACTLY Z6_T[gt,ht] = Z6[gt, ht+gt+3] for 12 | N (c-number = 1): the Z6 spin-structure shift of the modular probe, now on the full grid. Continuum target: Z6_cft[gt,ht] = |theta[gt/6, ht/6](0|tau)/eta|^2 with Casimir C(gt) = (6 nu^2 - 6 nu + 1)/3, nu = frac(1/2 + gt/6) (= 4 x the v628 per-class coefficient; C = -1/6, -1/9, 1/18, 1/3, 1/18, -1/9 for gt = 0..5). THE CANDIDATE ASSEMBLIES (all as weight tables w(gt,ht) on the Z6 grid; Z_cand = sum w(gt,ht) Z6[gt,ht]): A naive bosonic Z3: (1/3) sum_{g,h in Z3} Z[g,h] = sum_g P_{Q = 0 mod 3}[g] (no R sectors) A' "torsion" omega^{gh}: the U(1)-trivial relabeling, keeps Q = -g mod 3 per twist sector B the Z6 deck assembly: (1/6) sum_{gt,ht in Z6} Z6[gt,ht] = sum_{gt} P_{c=0 mod 6}[gt] -- the deck-invariant projection with the exact deck^3 = (-1)^F structure (all six spatial deck powers, Z6 charge projection of the modular probe M4.3) C1 GSO without R: Z6 charge projection c = 0 but only the three NS-type spatial sectors (gt even) C2 anti-GSO: c = 3 mod 6 on the NS-type sectors C3 Arf/GSO twin: (1/6) sum (-1)^{gt ht} Z6[gt,ht] = P_{c = 3 gt mod 6}[gt] (= B on even gt, opposite parity class on odd gt) W1/W2 must-fail weights: i^{gh} (an inadmissible mu4 "torsion") and (1/3)(Z[g,0] - Z[g,1] - Z[g,2]) -- NOT projectors; they exist to prove the integrality test has teeth. Checks: (H2.1) [machine] cohomology enumeration: exactly 27 mu3-valued 2-cocycles on Z3 = 9 coboundaries x 3 classes; EVERY cocycle is symmetric, so the discrete-torsion phase omega(g,h)/omega(h,g) == 1 identically; every class becomes a coboundary over mu9 subset U(1): H^2(Z3, U(1)) = 0 -- no discrete torsion exists for the Z3 orbifold. (H2.2) [machine] the U(1)-trivial phase tables omega^{a g h + b h} are EXACT charge-class relabelings: their temporal weight is the projector onto Q = -(a g + b) mod 3, nothing else. (M1.1) [machine] the Z6 sector grid: all 36 Z6[gt,ht] real >= 0, exact degeneracies Z6[gt,ht] = Z6[-gt,ht] = Z6[gt,-ht], Z6[3,3] = 0 exactly (the R,(-1)^F zero), and the even subgrid reproduces the modular-probe Z[g,h] convention (independent numpy crosscheck vs mpmath pipeline). (M1.2) [E] all 35 nonvanishing sectors match the continuum |theta[gt/6, ht/6]/eta|^2 at < 1 % on ln Z after removing the exact bulk N L/pi (N = 48; tau = i/2, i, 2i) -- NEW measured content beyond the modular probe: the R line and the half-twisted (odd deck power) lines; the continuum reference is itself exactly S-covariant (machine). (M1.3) [E] the assembly table: Z_cand at tau = i/2, i, 2i for N = 48, 96 (all six candidates); the O(1) candidates match their continuum assemblies at < 1 %; C2 has NO O(1) content: its leading exponent is Delta = 41/18 = 1/9 + 13/6 (the lightest Q = 3 states live in the TWISTED sectors, below the untwisted 5/2), fitted at < 2 %. (M2.1) [central] THE SPECTRAL TEST: the six candidate weight tables are exact per-sector charge projectors (temporal weight phi in {0,1} machine-exact) => every extracted degeneracy is a NONNEGATIVE INTEGER by exact arithmetic on the enumerated Fock spectrum (first levels tabulated); the (level, sector, charge, count) data at N = 48 and N = 96 are IDENTICAL with level residuals shrinking ~ N^{-2}; the must-fail weights W1/W2 produce complex / negative "degeneracies" -- the test has teeth. (M2.2) [machine] trace <-> spectrum consistency: for all 8 weight tables the assembled trace at L = 3N equals the enumerated spectral sum within the exp(-2 pi L/N * 1.34) tail bound (mpmath, 40 digits -- the C2 cancellations are 20 orders below double precision). (M2.3) [central] modular S MEASURED per candidate (tau = i/2 <-> 2i, N = 24/48/96): A, A', B, C3 converge monotonically with the stable ~N^{-4} rate (A' converges TOO: charge conjugation of the seam double identifies the omega^{gh} and omega^{-gh} relabelings -- the H2-trivial phases are S-consistent, an honest measured surprise); C1 and C2 are S-BROKEN: their deviations do not decrease (C1 lacks the R-type sectors that S generates; C2's charge-3 tower has no S-image). (M2.4) [central] T EXACT on the lattice (the deck^3 = -1 content): B, C1, C3 are machine-exactly T-invariant; A violates T EXACTLY by twice its Q = 3 mod 6 content (the operator identity Z_T(A) = Z(A) - 2 Z(C2), machine); C2 is exactly T-ANTI-invariant (Z_T = -Z); the per-sector Dehn identity Z6_T[gt,ht] = Z6[gt,ht+gt+3] holds machine-exactly on odd (half-twisted) sectors too. (M2.5) [E] vacuum: unique (multiplicity 1) for A, A', B, C1, C3; C2 has NO vacuum (dead as a theory). (M3.1) [E] the untwisted sector of the surviving assemblies is the charge-projected NS seam: neutral degeneracies {1, 4, 9} at Delta = 0, 1, 2 -- independent continuum q-series vs lattice enumeration (v623: untwisted = base, verbatim). (M3.2) [E] the twisted characters: Delta_sigma = 1/9 with assembly multiplicity 2 (the v639 sigma/sigma-bar pair, h_sigma = 1/36 per deck class); the charged {1/6, 5/6} parafermion pair at 1/9 + 1/6 is projected OUT exactly as the omega^{k q} charge bookkeeping demands; the next neutral twisted level is 1/9 + 1/3 (x2); independent q-series {1, 1, 2} matches. (M3.3) [E] the ground charge class is c = 0 in ALL SIX gt-sectors (extends modular-probe M4.3 to the odd deck powers: the Delta = 1/36 and Delta = 1/4 grounds are charge-0) -- the deck-invariant class carries every sector ground. (M3.4) [E/C] THE VERDICT: the survivors of {integer spectrum, unique vacuum, S measured clean, T exact} are exactly {B, C3}; the seam data discriminate: B keeps every measured sector ground (the c = 0 deck-invariant class, M3.3) and the trivial Klein phase eta = (1,1) of the RP probe; C3 (the Arf/GSO twin) excises ALL odd-sector grounds -- modular- consistent as an abstract fermionic orbifold but seam-alien. The seam orbifold is B. HONEST: A and A' die by the EXACT lattice T (deck^3 = -1) plus, for A', the v639 twisted exponent; C1 dies by S; C2 by vacuum + T-anti; the B-vs-C3 kill is the measured c = 0 ground bookkeeping plus the Klein triviality -- a data-backed [C] reading, not a modularity theorem. (M4.x) [E] CHIRAL PHASES: the half-band trace Z_chir[g,h] = prod_{k in (0,pi)} 2cosh((L eps_k - i lam_h)/2) is genuinely COMPLEX in the twisted sectors (the eps -> -eps pairing breaks for gt not = 0 mod 3); its phase against the chiral theta[g/3,h/3]/eta is measured over tau = i/2, i, 2i at N = 48, 96: CONSTANT in tau (drift ~1e-4 at N = 48, ~N^{-2}) with value e^{-2 pi i a~ b}, a~ = the symmetric-interval representative of a = g/3 (spectral-flow-reduced branch; for g = 2 the measured phase is +2 pi/9 = -2 pi (a-1) b, not -4 pi/9) -- the lattice trace is the theta quotient WITHOUT the characteristic phase e^{2 pi i ab}, measured. (M5.1) [C] typing: what stands, what is missing. Verdict enums (frozen): ORB-ASSEMBLY-SEAM (all pass; exactly one seam assembly), ORB-ASSEMBLY-DEGENERATE (consistency tests pass but the seam data cannot discriminate), ORB-ASSEMBLY-FAILS (grid or control level fails), MIXED (anything else). FIREWALL: GATE.QGEO does not move; no marker changes; the B-vs-C3 kill is data-backed [C] (measured ground classes + Klein triviality), not a modularity theorem -- v652 hardens it structurally.
