Modular Spectral Closure (v258–v261). The finite Dirac is a covariance induction of the seam KMS state, the spectral-action cutoff is that KMS weight (f₂/f₀ = 1), and seam, carrier-16 and E₈ live on one Kummer/K3 surface — so Dirac, cutoff, gauging, glue and orientability are readouts of one seam state. QGEO.SYM.01 is then a corollary (a conformal net's vacuum is rotation-invariant by axiom, v335).
Seam keystone.The keystone's residual is a composition of standard cited theorems (OS/clustering, the Kitaev free-fermion classification, the AQFT stack) over established TFPT facts — Lean-pinned to those named steps plus the derived gap Δ = 6·ln(3/2) ≈ 2.43 > 0, no undischarged TFPT-internal assumption. Its two heavy legs are literature-anchored (v336): the MMST continuum scaling limit and the Adamo–Moriwaki–Tanimoto OS reconstruction, with (E₈)₁ inside their range (c=8, rank 8, 16 Majoranas) — and the 128-spinor extension leg is now certified at net level by the peer-reviewed crossed-product package (v469, LR/Böckenhauer/KLM), with the AGT/AMT route demoted to an independent second witness; stays [O].
QG decoupling is a theorem (v337).Every readout factors through the gapped admissible spectrum (χ = 729/665, margin 1.648 > 0), so TFPT provably does not need the ambient measure.
4D-QFT fork (v265). Boundary QFT — closed modulo cited theorems; ambient QG — discharged as redundancy [C]; 4D GUT — not claimed (E₈ is the audit hull, not a 4D gauge group); optional UV branch — carrier-native Pati–Salam, falsifiable by thresholds and proton decay. The sprint-by-sprint reduction (v234 → v302) is on the changelog.
