While it computes, here's the one-line summary of the Track C opening:\n\n**The discovery from the literature sweep:** the Weil-form positivity frontier is *live right now* (four 2026 papers), and our project sits in an unoccupied niche — the Anthropic paper's G̃ is exactly a Weil-form truncation, but with an unconditional second-moment input that the Suzuki/Groskin truncation theory lacks. Conversely, their certification budgets (Groskin's B_T rule) are language our framework doesn't have. The cross-pollination questions are formulated (Q-3.4a/b/c in D-014).\n\n**E-006 measures the \"positivity horizon\":** how close to singular our truncated Weil form gets as the support grows (bandwidth λ = 0.5 → 2.0). If the eigenvalue floor decays superexponentially (as Kim et al. found for Suzuki's operator), that's a *complexity wall* for the whole positivity route — certification would need precision growing faster than exponentially in the support. Exactly the kind of obstruction-map measurement this project is built to make.\n\nI'll report the numbers as soon as it lands."}]
