We present a refined effective framework in which matter inside black holes undergoes a sequence of phases — quark–gluon plasma (QGP), color–flavor–locked (CFL) / Bose–Einstein condensation (BEC), and a loop quantum cosmology (LQC)–type bounce — culminating in nonsingular “Siamese” universes. The model includes explicit guardrails: mesoscopic validity (R ≫ ξ ~ 1/Δ), curved-GL perturbative treatment of σ(R), compact Israel–Darmois junctions, flat-prior parameter scans (≈10% bands), and a holographically guided dissipation proxy with C ∈ [0.5, 2]. Synthetic estimates include Tolman corrections O(1–5%) in Δt/H, ~3% reduction of σ at R/ξ=20, and ~15% damping in

This is an effective scoped toy model. Proxies (Tolman, curved-GL O(λ), dissipation C) are used to quantify trends, not to claim ab initio microphysics near black hole horizons.
All numerical values in the figures are synthetic illustrations only; they should be replaced by calibrated ETK outputs in future simulations.
