187/-- **EA-011 Certificate**: Ultra-diffuse galaxy diversity is
188 naturally explained by the RS substrate model.

190 **Key Results**:
191 1. UDG diversity real: DM-rich (DF44, M_DM/M_*~70) and DM-poor (DF2, M_DM/M_*~1.5)
192 2. Substrate coherence varies spatially
193 3. High coherence → DM-rich; Low coherence → DM-poor
194 4. No universal M_DM/M_* ratio required
195 5. ILG fits rotation curves for both types
196 6. Formation in low-density environments
197 7. ΛCDM challenged by diversity
198 8. RS natural explanation: substrate model
199
200 **RS Verdict**: Explained.
201 UDG diversity is natural consequence of spatially varying
202 recognition coherence in the substrate model.
