The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

The presence of the chiral (C4H9FN)+ organic cation induces formation of chiral magnetic order, even though the inorganic sublattice itself is structurally centrosymmetric.

C2weakest assumption

That the observed second-order magnetoelectric effect arises specifically from field-induced magnetic chirality transferred from the organic cations rather than from defects, impurities, or other structural asymmetries not fully ruled out by the racemic control.

C3one line summary

Chiral organic cations induce chiral magnetic order in a centrosymmetric Cu-Cl inorganic sublattice, shown by a second-order magnetoelectric effect present only in the enantiopure (R/S) variants and absent in the racemic control.
