What this work contributes
Bulk strain reconstructions reveal broad tetragonal-like regions within the orthorhombic phase and fine orthorhombic-like features at low temperature.
Where the evidence stops
Direct spatial correlation with electronic response remains open. No demonstrated improvement in superconductivity, optical force, graphene performance or Alpha 1 coupling. Heterogeneity was previously known; the advance concerns bulk spatial organization.
