UTFANSWF v23 — FINE-STRUCTURE TECHNICAL RECORD
Release: v23 / September 1, 2026

NON-EXECUTABLE GLOBAL RESEARCH RECORD
alpha_hat^-1(MZ) = 128.11763024
alpha1^-1(MZ) ~= 59.0815
alpha2^-1(MZ) ~= 29.6486
s_hat^2(MZ) = 0.2314165965
held-out s_eff^2 ~= 0.2315066 vs comparison 0.231530; residual ~= -2.34e-5

CONDITIONAL THOMSON TRANSPORT
Data-driven HVP: Delta alpha_had^(5) = 0.027629 +/- 0.000038 +/- 0.000062
alpha^-1(0) = 137.03912504
HVP-only sigma in inverse alpha ~= 0.01025
Withheld Thomson value is about 0.305 sigma from the data-driven-HVP central prediction.
Verdict: PASS_CONDITIONAL_DATA_DRIVEN_HVP

OTHER HVP BRANCH
2025 CLS lattice+pQCD HVP = 0.027813(33)_lat(35)_pQCD -> alpha^-1(0) ~= 137.06506. This branch remains in genuine tension and is not tuned away.

HISTORICAL ROW 27 CHECKPOINTS
Blind checkpoint: 137.03735243
Verified post-mixed rung: 137.00222764
Withheld comparison after freeze: 137.035999177
Executable Row 27 reproduces these preserved checkpoint/rung values at Diagnostic PASS scope. The later HVP branch above is separate NON-EXECUTABLE RESEARCH / conditional transport. No source-complete endpoint is promoted.

BLIND CONTRACT
No measured electromagnetic alpha used as solve input; no fit to 1/137; no hidden normalization; holdout used only after freeze.
Verification-bundle SHA-256: 9ce68f81e05a438398c901488a09c8815453c5ba02395ed8fb85bb3709b3ae50
Independent verification status: requested/pending.

FAILURE CONDITION
Violation of the blind contract, failure to reproduce the frozen upstream/EW chain, or failure of the stated conditional HVP transport invalidates the corresponding claim.

OPEN BOUNDARIES
Executable Row 27: the final source-complete electroweak/GRIFFIN handoff and Jacobian remain open. Preserved endpoint-calibrated GRIFFIN diagnostics do not complete it. The separate UV/GUT route requires independently derived heavy-threshold boundary data.

Later non-executable HVP research branch: a complete first-principles no-external-hadronic-input endpoint requires a source-complete nonperturbative light-quark HVP/current-current calculation with controlled continuum/volume limits and common short-distance matching.

NO COMPLETE 1/137 DERIVATION IS CLAIMED.
