This addendum extends the Elevated Complex Zero-Gap Core (ECZC) model by introducing a discrete, quantized growth mechanism for mass accretion. Rather than continuous assimilation, the core boundary expands through surface-energy-minimizing coalescence events mathematically analogous to merging soap films governed by Plateau's laws. Each discrete accretion event deposits a single Planck-bounded membrane shell onto the absolute-zero core, mimicking the flux quantization observed in Type II superconductors. This mechanism predicts that mass absorption emits a distinct sequence of individually resolved gravitational wave ringdown pulses rather than a smooth decay curve, providing a clear observational signature for next-generation interferometers like LISA and the Einstein Telescope. This work is an operational supplement to the parent paper (DOI: 10.5281/zenodo.20534658).
