Overview
Abstract
The leading Weyl profile of a rapidly twisted tube with a fixed connected step section annihilates every odd logarithmic harmonic of inverse twist speed. A preceding heat-trace result detects the fundamental harmonic. This paper gives a computer-assisted resolution for the original third harmonic without changing the section or adding a lower-order perturbation. A half-strip resolvent formula and complete residual estimates enclose a complex Mellin invariant of the connected junction. Sectorial trace bounds reduce the certified quadrature to 27 complex nodes while retaining infinite tails, arithmetic error, node conversion and aliasing. The resulting Mellin modulus is below 5.653 × 10⁻⁶, whereas cancellation requires a modulus above 1.13 × 10⁻⁵; the third heat coefficient therefore has modulus greater than 5.08 × 10⁻⁵. The source certificate states its arithmetic assumptions and regenerates its inputs. Higher odd modes and finite-spectrum stability are outside this paper’s scope.

Scope of the work
Computer-assisted detection of the original third Weyl-blind harmonic in the fixed connected polar-strip geometry. Includes the complete infinite-aperture and arithmetic error bounds under the stated implementation contract. Ideal asymptotic audibility only; no stable finite-spectrum inversion, all-odd theorem, arbitrary independent two-end recovery or unsmoothed second counting term.
Reproduction notes
The complete package contains the manuscript, editable source, certificate code, reader instructions, citation metadata and checksums. Its source regenerates the 27 connected-aperture node disks and scalar acceptance tests. The reference implementation uses CPython 3.12, NumPy 2.3.5 and the explicit IEEE binary64 contract described in the paper and README.
