A many-body winding invariant based on Pancharatnam phases uniquely determines the 4^ν entanglement-spectrum degeneracy scaling in interacting generalized SSH chains, establishing symmetry-protected bulk-boundary correspondence.
Cavity-mediated interactions in an effective SSH Hamiltonian produce consistent topological phase diagrams across three markers, confirming edge states via correlations.
