UTFANSWF v23 — HEAVY-THRESHOLD TECHNICAL RECORD
Release: v23 / September 1, 2026

AUTHORITATIVE STATUS
Corrected pinned-input heavy-threshold closure: consistency diagnostic.
Target-free heavy-ratio sector retains a continuous modulus and does NOT uniquely select sqrt(2)/5.
No blind heavy-boundary claim is promoted.

ACTIVE CORRECTED PINNED-INPUT CLOSURE DIAGNOSTIC
M_HC = 1.8700319286833188e16 GeV
M_X = 1.0831613303122448e16 GeV
M_Sigma = 1.0831613303122448e16 GeV
alpha_U^-1 = 25.79100322800608
closure spread in inverse coupling = 3.552713678800501e-15
blind prediction = false

FROZEN PSN RESEARCH BRANCH
alpha_U^-1 = 8*pi
M_HC/M_X = M_Sigma/M_X = sqrt(2)/5
This ratio is a self-consistent PASS_CANDIDATE boundary for that branch, not a uniquely forced UTFANSWF prediction. The global heavy-ratio/projector closeout leaves a continuous one-parameter modulus. Exact-Z6 proton stability is independent of the numerical r value.

OPEN BOUNDARY
Derive a source-complete boundary equation that uniquely fixes the heavy/family orientation without importing desired observables, then globally re-close.
