Finite-Width Curvature Layer, a Smooth Candidate's Surpassing Result, and Dual-Path Support Cross-Checks

Using an endpoint-normalized hyperbolic-tangent layer to smooth the internal kinks of the five-link's side wings, we originally expected ε→0 to simply converge back to the polyline event root, but numerical continuation reveals a stronger, non-monotonic phenomenon: a smooth curvature layer of intermediate width can sit slightly above the polyline event root itself. The best candidate is s*=0.998914339084632, about 1.058×10⁻⁵ above the five-link event control s₀=0.998903757132509. This corrects the simplified account from Round 7 that “curvature concentration only recovers the polyline limit” — spreading the curvature too wide lowers the pressure, concentrating it too narrowly returns to the polyline, and an intermediate width can produce a small surpassing gain. This has been cross-checked through a multi-resolution audit and an independent support-path method using a dense point cloud of about 240,000 points (the two methods agree at the 10⁻¹⁴ level), but arbitrary-precision and interval-certificate confirmation are still pending.

Exploratory numerical research; not a formal proof; not an interval certificate — Stage status as stated by the package's own documents, reproduced verbatim. Continues Moser Skew Lab v0.7.

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

“The real result is the discovery that the five-link polyline platform can be slightly surpassed by a finite-width smooth curvature layer. This result has been cross-checked through multi-resolution and dense-point-cloud support checks, but arbitrary-precision and interval-certificate confirmation are still pending.” — from Section 12, “Conclusion,” of this package's main document.

Round 8 Dense Point-Cloud Cross-Check

An independent method that does not use tangent–normal stationary-point inversion, computing directly over 240017 points, supporting that the finite-width positive gain is not an artifact of a single implementation.
