Round 13 v0.13 2026-07-26

The Smooth Five-Parameter Event–KKT System, Isolation, and Peak Correction

The five parameters p=(w,β,δ,c,ε) handed off from Round 12 are formally written as a 12-unknown event–KKT system: equal height across the four controlling branches (two low-phase stationary points, 120°, 270°), dual stationarity conditions, branch-pressure-weighted gradient balance, and multipliers summing to one. Solving it gives s₁₃=0.998914343297485, only about 4.2×10⁻⁹ higher than Round 8 — a fine correction to the peak's location, not a new geometric-scale breakthrough. The full 12×12 Jacobian is numerically full rank, but its condition number is as high as about 3.77×10⁷, highly ill-conditioned: this supports numerical isolation but not a robust conclusion of interval invertibility. The 120° branch carries about 73.6% of the branch pressure, the 270° branch about 20.7%. All 20 random perturbations converge back to the same scale basin.

Numerical event–KKT reconstruction; not an interval KKT certificate; not a formal proof — A stage-status self-declaration from the package's own documents, reproduced as-is. Continues Moser Skew Lab v0.12.

Relationship to other packages, stated as far as possible in the document's own words, not my interpretation.

“The most accurate description at present is: a finite-width tanh curvature layer forms a numerically isolated, but highly ill-conditioned, minimax candidate within the five-parameter family.” — from Section 15, “Conclusion,” of this package's main document.
