VERDICT: LEAN Darderi Qualitative read (freshness + DOM vs Strong vs Vallejo's tiebreak grinds on a heavy schedule) validates the B side, but ELO already matches the 1.47 price, ML actively disagrees toward Vallejo, and the blended value edge is only 3.8%. No meaningful model-market disagreement → the fatigue story is priced. Lean Darderi, no stake.
