Butterfly Crystal: Reproducible Growth and a Lorenz Reference Calculation

We identify two saved butterfly-labelled findings, reproduce the later growth record from its constructor, and compare the separate Lorenz reference integrator against an independent calculation. The result provides a reproducible morphology baseline and a bounded numerical audit for subsequent deterministic-sensitivity experiments. This preprint preserves the named finite computational results and their stated scope. The restricted accompanying package includes the manuscript, claim ledger, finding-specific data, source-result records and a portable archive/elementary-control verifier. Forge/ISA implementation is excluded. Copyright2026 David Glowalla; no additional reuse permission is granted.
