"""v165 -- Premise (A), the honest maximal closure: the two residual gates of
the seam-Gaussianity chain (A2 net existence, R1 seam clock) are pinned to
their floor, so premise (A) carries ZERO independent open content -- it is an
assembly of established mathematics plus the one already-open realisation gate
(GATE.QGEO) plus the irreducible {pi, v_geo} core (a THEOREM, not a defect, by
the No-Unit Theorem v153).

The (A)-chain so far: v160 (fixed-point theorem) -> v161 (cone gap = one-particle
gap; the cone is eliminated) -> v162 (the one-particle symbol's numbers are
forced; (A) factors into the already-open A2 + R1).  This module discharges A2
and R1 as far as they go and writes the final gate accounting.

  [C] 1. A2 (NET EXISTENCE) CLOSES BY ASSEMBLY OF ESTABLISHED MATHEMATICS.
         Every ingredient of the target net is a constructed object, not open
         research: (a) the 16 free Majoranas define a free-fermion conformal net
         (Buchholz-Mack-Todorov / Boeckenhauer-Evans); (b) the holomorphic c=8
         lattice net is (E8)_1 (Frenkel-Kac-Segal VOA; Dong-Xu conformal net;
         Kawahigashi-Longo machinery); (c) the mu4 simple-current extension is a
         Longo Q-system of index 4 (v125), KLM mu-index 16/16 = 1 => holomorphic;
         (d) the modular data is checked: 248 = 120(NS) + 128(R), character
         E4/eta^8 = j^{1/3} (v156).  The ONLY TFPT-specific identification -- that
         the seam Calderon kernel IS the free-fermion two-point function -- is
         done, because the DtN/Calderon symbol is universally omega_k = |k|
         (Lee-Uhlmann; v156/v157).  So A2 is not a finite computation we owe; it
         is the citation/assembly of published net-construction theorems with the
         one TFPT input supplied.  Re-typed [A] -> [C] (closed by assembly).
  [C] 2. R1 (SEAM CLOCK) REDUCES TO GATE.QGEO BY THE UNIQUENESS OF A0*.  A
         mu4-equivariant generator is diagonal in the cusp basis (the deck
         average is the diagonal projection, sum_k U^k X U^{-k} = |mu4| diag X)
         and the mu4-equivariant admissible FLAT gapped generator on the carrier
         is UNIQUE -- it is A0* (v115/v116), spectrum {0,1/3,2/3}, transfer
         eigenvalues (1-alpha)^{p2} = {1,(2/3)^6,(1/3)^6}.  So IF the seam
         boundary generator lies in that class, its gap and grading are FORCED;
         the seam clock = the flavour wall = the horizon clock (one operator,
         v54).  The residual is exactly one geometric identification: the seam
         collar boundary carries the flat mu4-parabolic connection of the
         punctured sphere P^1 minus mu4 -- which IS GATE.QGEO (the parabolic
         realisation of Q).  The cohomological half is already established
         (v137: the cusp grading = the A3 grading on H^1(P^1 minus mu4),
         b1 = 3 = N_fam).  So R1 is not a new gate; it is GATE.QGEO.
  [O] 3. THE IRREDUCIBLE CORE IS A THEOREM, NOT A HOLE (No-Unit Theorem v153).
         A dimensionless boundary compiler provably cannot fix an absolute scale,
         so the irreducibles are exactly {pi, v_geo}; closing (A) introduces NO
         new irreducible.  The one geometric postulate behind GATE.QGEO (seam
         boundary = the mu4-punctured sphere) is the structural seam=flavour=
         horizon identification -- the unifying content of the theory, in the
         same irreducible class.  "Zero inputs" is provably unreachable; the
         honest endpoint is a NAMED minimal core, not a mystery.
  [E] 4. THE FINAL GATE ACCOUNTING.  Premise (A) -- once a diffuse
         "find a free bulk / constructive-QFT" gap -- now has ZERO independent
         open gates: it equals (A2 assembly, [C]) + (R1 = GATE.QGEO, already
         open) + (the {pi, v_geo} irreducible core, a theorem).  The count of
         independent open structural items does not increase; (A) ceases to be
         its own gate.

Honest scope: this is the maximal HONEST closure -- a unification and a re-typing,
NOT an unconditional proof.  A2 [C] means "reduces to published theorems"; R1
[C]->GATE.QGEO means "no new gate, it is the realisation premise"; the irreducible
core stays [O] by a theorem.  Python-only (consistency re-verification + the
mu4-uniqueness lever + the accounting); no new exact-identity content for Wolfram.
