Initial data for a time machine from dust: an explicit composite construction with a certified ordinary-density scaling regime

Preprint. An explicit composite initial-data construction: vacuum pp-wave core, umbilical slice, dust envelope, and a verified hand-off to Ori outer layers. The full-layer retune makes both gates positive; ordinary density is a certified scaling extrapolation at depth. Published on LibertAI Labs: https://labs.libertai.io/papers/hybrid-construction/.

Abstract

Preprint. An explicit composite initial-data construction: vacuum pp-wave core, umbilical slice, dust envelope, and a verified hand-off to Ori outer layers. The full-layer retune makes both gates positive; ordinary density is a certified scaling extrapolation at depth. Published on LibertAI Labs: https://labs.libertai.io/papers/hybrid-construction/. First public timestamp: 2026-10-27T16:15:00Z (UTC). SHA-256 of the PDF: 6b6844a17539016302b1a2c26b2b05d0399975bee47092004267f4243443b866.
