The stress test itself was run at\n$a \\in \\{4, 8\\}$; combined with the spectral-measure picture to\n$a = 12$ (floors $\\approx 1$ at the true ordinates, plateau\n$\\to 2a$), this amounts to a numerical verification of Weil\npositivity in the $\\mathcal H(T_a)$ metric at those scales, and an\noff-line pair produces negative form directions localized at its\nheight.\n\\end{remark}\n\n\\section{Obstruction note}\n\n\\emph{The $\\lambda \\to \\lambda_a^-$ ground-state channel}\n(G-004, D-046): the feasibility windows are disjoint \u2014 ground-state\nresolution requires $a \\lesssim 1.3$ (superexponential decay of\n$\\lambda_a$) while zero resolution requires $a \\gtrsim 4$.\n\n\\appendix\n\\section{Spectral-measure numerics (E-016--E-025)}\n\nAll experiments are deterministic scripts with CSV+JSON sidecars in the\nproject archive (\\texttt{research/numerics/}); checks as stated.\n\n\\begin{itemize}\n\\item Galerkin realization of Suzuki's Weil-form operator validated\nagainst the zero-side explicit formula to $4.5\\times10^{-6}$;\nzero-location by sign-change + Brent refinement; winding-number\ndiagnostics for off-axis zeros.\n\\item Clark/de~Branges weights $1/K_a(z_k,z_k)$ via Schur-reduced\nbordered Toeplitz solves (validated to $3.6\\times10^{-14}$ against\ndense bordered solves; $h$-refinement $1.1\\times10^{-3}$).\n\\item Valley observable: $\\Delta(a) = 2.16, 2.51, 2.74, 2.87, 2.94$\nfor $a = 4,6,8,10,12$; plateau $K \\to 2a$ (measured ratio\n$0.973 \\to 0.997$); valley floors $\\approx 1$ (mass gauge\n$m_\\gamma = 1$; measured $0.90$--$1.26$ across $a = 4, \\ldots, 12$);\nmass within $\\pm0.1$ of true zeros $63\\% \\to 72.5\\%$; positional\nlocking $\\approx 0.65/a^2$; residual $\\to Z/(2\\pi)$.\n\\item $\\theta$-independence (E-024): residual spread at most\n$2.23\\%$ over $7$ boundary conditions $\\times$ $3$ values of $a$.\n\\item $\\lambda$-flow (E-025): discretization floor documented\n(pencil bottom crosses zero at $a \\approx 5.2$ for $h = 0.01$,\n$O(h)$ artifact); channel response measured at $a=4$\n($\\Delta\\colon 2.16 \\to 6.99$, residual $48 \\to 11$).\n\\item Detector stress test (E-027): a synthetic off-line zero pair\n(mid-gap heights $23.0$, $51.4$; $a \\in \\{4,8\\}$; Legendre--Galerkin\nzero-side form, $N > \\gamma^* a$) confirms the three-level detector\npicture: bare-form negativity onset immediate ($\\sim 10^{13}\\times$\ncontrol floor at the smallest $\\delta$), pencil positivity loss at\n$\\delta \\approx 0.11$ ($a=4$) / $0.038$ ($a=8$), tuned-carrier\nthreshold at $\\pi/(2a)$ to within $2.3\\%$ in the worst case\n(three of four cases within $0.5\\%$); negative directions\nlocalized at the pair (contrast $3.4$--$6.1$).\n\\end{itemize}\n\n\\bibliographystyle{plain}\n\\bibliography{references}\n\\end{document}\n"

Plateau upper bound:\n$T_a \\ge I$. Floor: single-term domination above; below, the flat\nbump for isolated zeros, and in general the projection of $e_\\gamma$\noff the span of the nearby evaluation vectors (which vanishes exactly\nat the neighboring zeros). The combinatorial input is Trudgian's\nzero-density bound.\n\\end{proof}\n\n\\begin{remark}[the detector content; D-050, E-027]\nThe detector has three levels (measured, E-027; all four cases\n$a \\in \\{4,8\\}$, two heights): (L1) the bare Weil form is indefinite\nfor \\emph{any} off-line deviation $\\delta > 0$ (strict Schwarz on the\ntwo evaluation functionals; no threshold), with tiny magnitude near\n$\\delta = 0$; (L2) the pencil $T_a = I + B_a$ loses positivity at a\nmagnitude-set onset (measured $\\delta \\approx 0.11$ at $a=4$,\n$0.038$ at $a=8$); (L3) the tuned flat-carrier quotient turns negative\nexactly at $\\delta = \\pi/(2a)$ (proved one-direction; measured\ncrossings within $0.02\\%$--$2.3\\%$ of $\\pi/(2a)$, three of four\ncases within $0.5\\%$). The stress test itself was run at\n$a \\in \\{4, 8\\}$; combined with the spectral-measure picture to\n$a = 12$ (floors $\\approx 1$ at the true ordinates, plateau\n$\\to 2a$), this amounts to a numerical verification of Weil\npositivity in the $\\mathcal H(T_a)$ metric at those scales, and an\noff-line pair produces negative form directions localized at its\nheight.\n\\end{remark}\n\n\\section{Obstruction note}\n\n\\emph{The $\\lambda \\to \\lambda_a^-$ ground-state channel}\n(G-004, D-046): the feasibility windows are disjoint — ground-state\nresolution requires $a \\lesssim 1.3$ (superexponential decay of\n$\\lambda_a$) while zero resolution requires $a \\gtrsim 4$.\n\n\\appendix\n\\section{Spectral-measure numerics (E-016--E-025)}\n\nAll experiments are deterministic scripts with CSV+JSON sidecars in the\nproject archive (\\texttt{research/numerics/}); checks as stated.\n\n\\begin{itemize}\n\\item Galerkin realization of Suzuki's Weil-form operator validated\nagainst the zero-side explicit formula to $4.5\\times10^{-6}$;\nzero-location by sign-change + Brent refinement; winding-number\ndiagnostics for off-axis zeros.\n\\item Clark/de~Branges weights $1/K_a(z_k,z_k)$ via Schur-reduced\nbordered Toeplitz solves (validated to $3.6\\times10^{-14}$ against\ndense bordered solves; $h$-refinement $1.1\\times10^{-3}$).\n\\item Valley observable: $\\Delta(a) = 2.16, 2.51, 2.74, 2.87, 2.94$\nfor $a = 4,6,8,10,12$; plateau $K \\to 2a$ (measured ratio\n$0.973 \\to 0.997$); valley floors $\\approx 1$ (mass gauge\n$m_\\gamma = 1$; measured $0.90$--$1.26$ across $a = 4, \\ldots, 12$);\nmass within $\\pm0.1$ of true zeros $63\\% \\to 72.5\\%$; positional\nlocking $\\approx 0.65/a^2$; residual $\\to Z/(2\\pi)$.\n\\item $\\theta$-independence (E-024): residual spread at most\n$2.23\\%$ over $7$ boundary conditions $\\times$ $3$ values of $a$.\n\\item $\\lambda$-flow (E-025): discretization floor documented\n(pencil bottom crosses zero at $a \\approx 5.2$ for $h = 0.01$,\n$O(h)$ artifact); channel response measured at $a=4$\n($\\Delta\\colon 2.16 \\to 6.99$, residual $48 \\to 11$).\n\\item Detector stress test (E-027): a synthetic off-line zero pair\n(mid-gap heights $23.0$, $51.4$; $a \\in \\{4,8\\}$; Legendre--Galerkin\nzero-side form, $N > \\gamma^* a$) confirms the three-level detector\npicture: bare-form negativity onset immediate ($\\sim 10^{13}\\times$\ncontrol floor at the smallest $\\delta$), pencil positivity loss at\n$\\delta \\approx 0.11$ ($a=4$) / $0.038$ ($a=8$), tuned-carrier\nthreshold at $\\pi/(2a)$ to within $2.3\\%$ in the worst case\n(three of four cases within $0.5\\%$); negative directions\nlocalized at the pair (contrast $3.4$--$6.1$).\n\\end{itemize}\n\n\\bibliographystyle{plain}\n\\bibliography{references}\n\\end{document}\n"},"extra_content":null}]
