EOS-Δ-7 — Cross-code agreement — equations of state

EOS-Δ-7 contains 7 periodic structures, referenced against Cross-code Δ-gauge (Lejaeghere 2016 / Bosoni 2024), released as r2026.2. It scores Δ-gauge (meV/atom).

Reference generation: Δ-gauge on Si, Al, Cu, TiO₂, NaCl, Fe, LiF; E–V −10%…+16%, 21 points; identical structures and magnetic states for every code

Provenance: Generated in-house following the Lejaeghere/Bosoni verification protocol
