Companion source archive for Finite-core Volterra reductions for a Weyl-positive Riemann phase kernel

Source-only reproducibility and audit archive for Finite-core Volterra reductions for a Weyl-positive Riemann phase kernel. It contains the current Python verification scripts, theorem JSON ledgers, fail-closed audits, deterministic numerical outputs, manuscript TeX, and Lean sources frozen on 2026-08-14. Generated PDFs, images, compressed archives, caches, virtual environments, and historical release directories are excluded from the archive contents. The original Riemann-kernel application is refuted as stated; the coercive augmented replacement is proved only for its reformulated audit, while the exact augmented-to-zeta transfer and limiting spectral threshold-buffer route remain open. No proof of the Riemann hypothesis is claimed.
