record GL638 real soft and Cut3 channel checks Retain the full local soft/replacement and supported Cut3-channel evidence, matched leading cards, and independent audits. Single-soft real weights need explicit gluon coverage; double-soft real scaling remains unresolved. The new Cut3 channel helps the recorded real maximum locally. No new Monte Carlo winner or global boundedness claim is made. Plan the 600 GeV and matched UV-scale study. Validation: 120 soft rows/480 native evaluations, 15,050 qualified checks; 21 Cut3 rows/84 native evaluations, 2,681 checks; 113 independent spot checks; 226 original/archive hashes verified plus two retained independent-audit files. User requests: "Continue as planned, but focus on the real part here only (it's what matters fro cross-section, the imaginary part drops out because of unitarity when combined with the CP symmetric variant of that forward scattering graph)." "Continue as planned, but ok then I guess the extra soft channel is necessary; the goal is to have as few known regions with unbounded integrand (i.e. ideally none)." "Continue as planned, but which `sqrt(s)` are you running this cross-section computation for? 1000 GeV? It may be more stable and thus better to start with 600 GeV or so, i.e. closer to production threshold." "Also mu_r should be kept to the z-mass at 91.188 GeV, and m_uv can be maybe lowered to 50 GeV or so (you can see if there is sensitivity on this, the central value must be independent of it, but the error may be a bit better at slightly smaller values of m_uv; to be checked)."
