P65: Tidal Deformability of CCEGA Black Stars — Λ ≠ 0 as a Surface Signature

We compute the tidal deformability Λ of CCEGA black stars. Two results: (1) Λ_BS is frequency-independent during inspiral — fISCO < fcut throughout the chirp. (2) Λ_BS ≈ 0.005–0.66 for masses 4.56–14.75 M☉, nonzero in contrast to GR black holes (Λ_BH = 0). For normal neutron stars, CCEGA predicts Λ ≈ 377–538 for M = 1.4 M☉, consistent with GW170817 (within 90% CI). A mild tension exists at the upper end, constraining k₂^CCEGA ≲ 0.07. ET stacking of ~100 mass-gap mergers could detect Λ̃ ~ 0.3 statistically.
