arXiv:2602.17656 - Exotic critical states as fractional Fermi seas
in the one-dimensional Bose gas.

Key insight: GHD occupancy ϑ(λ) ∈ [0,1] with bound 1/(2W+1) maps to
manifold witness scalar. The discrete scale-band progression matches
ncDerived scale-band logic.

+    notes: "Fractional Fermi seas (FFS) via interaction cycles in Lieb-Liniger model. Key math: GHD equation ∂_t ϑ(λ) + a_eff(λ) ∂_λ ϑ(λ) = 0 with occupancy ϑ(λ) ≤ 1/(2W+1). Potential model for manifold scaling: ϑ(λ) ∈ [0,1] provides witness-like scalar; 1/(2W+1) gives discrete scale-band progression matching ncDerived scale-band logic."
