Non-Convex Area-Exposure Tension and the First Curve–Container Alternating Adversarial Cycle

The research question formally shifts: no longer “which curve is hardest to fit inside some convex hull,” but “which curve, even exploiting the container's existing non-convex recesses, still leaves the largest exposed area.” The first complete cycle C₄→γ₅→C₅: the Fourier-12 attack curve exposes 0.00666, container reconfiguration absorbs 57.7%, leaving a net increase of only 1.47%. Held-out sample testing confirms the system has not yet converged.

Finite Fourier family, finite placement search, and non-convex container coordinate-descent candidate — Stage status as stated by the package's own documents, reproduced verbatim. “Genuine universal-container research must be an alternating contest between curvature functions and non-convex containers, not merely ranking curves against a fixed convex container.”

Relationship to other packages, stated as far as possible in the document's own words, not my interpretation. This case's theoretical foundation is in From the Original Kakeya Needle to Moser's Worm.

“This round directly quantifies, for the first time: curve attack pressure → container-reconfiguration absorption → net container increase. Result: roughly 57.7% of the initial exposure pressure can be absorbed by reconfiguration…so computing only ‘the new curve's exposure against a fixed container’ overstates the long-run area increase of a universal container; the container's response must be accounted for first.” — from Section 9 of this package's main document.
