# UTFANSWF 1/137 Global Closeout — 2026-08-18

**Status:** private/scratch research checkpoint only  
**Production:** untouched; no changes to production PDF, main.tex, or protected bundles.

## Blind contract
- No measured electromagnetic alpha used to set the UV/GUT/SUSY solution.
- No inverse-137 target fitting.
- Thomson alpha is comparison-only after upstream freeze.
- alpha3(MZ)=0.1184 owns the QCD/heavy-scale closure.
- GF and MW own the remaining absolute low-SUSY spectral scale.
- s_eff^2 is a held-out electroweak check.
- HVP is explicit at the final low-energy transport layer; it is not used to tune upstream parameters.

## Frozen global upstream chain
Primitive/minimum-norm spectral normalization (PSN) is treated as a new global UTFANSWF extension candidate, not as a theorem of the old public axioms.

Heavy boundary:
- alpha_U^-1 = 8*pi
- M_HC/M_X = M_Sigma/M_X = sqrt(2)/5

Full low-SUSY gauge-visible spectrum under PSN v2:
- T = 2568.37797 GeV
- m_D = T/sqrt(2) = 1816.11748 GeV
- m_S = sqrt(2) T = 3632.23496 GeV
- mu_Higgsino = M2 = M3 = m_H(extra) = T

QCD reclosure:
- M_X = 2.0387773e16 GeV
- M_HC = M_Sigma = 5.7665330e15 GeV

Frozen electroweak outputs:
- alpha1^-1(MZ) ~ 59.0815
- alpha2^-1(MZ) ~ 29.6486
- alpha_hat^-1(MZ) = 128.11763024
- s_hat^2(MZ) = 0.2314165965

Held-out weak-angle check using the established two-loop MSbar conversion band:
- central s_eff^2 prediction ~ 0.2315066
- comparison value = 0.231530
- residual ~ -2.34e-5
- verdict: PASS_CANDIDATE within published electroweak scheme/theory spread.

## Proton cross-check
Using the previously frozen D6 normalization and tau_p(D6) proportional to M_X^4:
- tau_p(D6) ~ 7.28e36 yr
- the new global threshold strengthens rather than weakens this channel.
- exact Z6 branch separately forbids isolated DeltaB=1,2 and first allows DeltaB=3.

## Modern single-scheme MZ -> 0 transport
Use SMDR v1.3 / Degrassi-Gambino-Giardino-compatible Sommerfeld-alpha transport only. Do not mix with the older Degrassi-Vicini bookkeeping.

For frozen alpha_hat^-1(MZ)=128.11763024:
- with Delta alpha_had^(5)=0.027600: alpha^-1(0)=137.03503737
- withheld Thomson comparison: 137.035999177
- central miss = -0.00096181 (~7 ppm in inverse alpha)

Using the independent 2023 cross-section-driven HVP determination:
- Delta alpha_had^(5)=0.027629 +/- 0.000038 +/- 0.000062
- predicted alpha^-1(0)=137.03912504
- central miss = +0.00312586
- propagated HVP-only sigma in inverse alpha ~ 0.01025
- holdout displacement ~ 0.305 sigma
- verdict: PASS_CONDITIONAL_DATA_DRIVEN_HVP

Post-freeze diagnostic only (not a solve input):
- exact-closure HVP would be Delta alpha_had^(5)=0.02760682355
- this is ~0.30 sigma from the independent 2023 cross-section-driven central value.

Current lattice branch:
- 2025 CLS lattice+pQCD: Delta alpha_had^(5)=0.027813(33)_lat(35)_pQCD
- frozen UTFANSWF+SMDR transport gives alpha^-1(0) ~ 137.06506
- this branch is in genuine tension with the data-driven branch and with the frozen central UTFANSWF transport; do not hide or tune it away.

## Hadronic sealed-room attempt
The preserved UTFANSWF v0 step spectral model gives:
- C_had = 3.5138614288
- at frozen alpha_hat^-1(MZ), Delta alpha_had^(5) ~ 0.02742684
- shortfall from exact-closure diagnostic ~ 1.80e-4 (~0.65%).

A simple target-free leading pQCD continuum upgrade to the charm/bottom steps gives a correction of order +9.7e-4, overshooting the needed movement by roughly a factor of five. Therefore no threshold/resonance/QCD coefficient is tuned.

The remaining truly sealed-room task would require an independently derived nonperturbative light-quark HVP/R(s) calculation (e.g. lattice-QCD-equivalent information) from the QCD sector. That is a separate hard problem and is not solved here.

## Final research verdict
**PASS_GLOBAL_UPSTREAM_NORMALIZATION_AND_EW_CLOSURE__PASS_CONDITIONAL_THOMSON_ON_DATA_DRIVEN_HVP__OPEN_NONPERTURBATIVE_HVP_FIRST_PRINCIPLES_CLOSURE**

Meaning:
1. The previous low-energy absolute-GRIFFIN route remains closed and is not revived.
2. A new global UV->GUT->full-SUSY->EW chain fixes the absolute MSbar electromagnetic normalization upstream without using 1/137.
3. The held-out weak-angle check survives.
4. Modern single-scheme SMDR transport lands extremely close to the Thomson value and passes statistically on the independent data-driven HVP branch.
5. A complete no-external-hadronic-input derivation is NOT claimed; nonperturbative HVP remains the final open first-principles wall.
6. Production artifacts remain unchanged.
