      "The concentration is item-driven, not relationship-driven — one SKU (Phthalo Green TF-2178 Master Pigment) IS 94.7% of the spend, sourced exclusively from Vorenza's Antwerp plant. Diversification work has to start at the BOM level, not the vendor master.",
      "Per-SKU pricing discipline is excellent (weighted CV 0.057) — Vorenza honors contract pricing. Risk is continuity, not extraction.",
      "Recommended next steps: (1) qualify Krellix Color USA and Sterling Color Inc. on the TF-2178 grade for dual-source eligibility; (2) raise safety stock to 90 days; (3) re-baseline after the European phthalocyanine REACH amendment ruling expected 2026-Q3."
