+No-cost cost-sourcing — SAFE first pass (Steps 2-5). READ-ONLY, NO DB WRITES.
+
+Owner: vp-dw-commerce. Plan: ~/.claude/yolo-queue/pending-approval/no-cost-vendor-cost-sourcing.md
+
+Produces, all read-only:
+  Step 2  vendor-classification.json  — auto-bucket all flagged vendors by
+          (cost_col_exists, cost_col_populated_pct, exact_join_pct, discount).
+  Step 3  exact-sku relink (dry-run)  — exact mfr_sku join flagged -> catalog cost.
+  Step 4  fuzzy pattern+color relink (dry-run) for the 4 cost-already-in-DB vendors
+          (Scalamandre, Rebel Walls, Osborne, Coordonné), DTD A+B+C confidence scheme:
+            A  tier by exactness: exact-pattern AND exact-color = HIGH;
+               pattern-exact + color-fuzzy/missing = REVIEW; pattern-fuzzy = LOW/exclude.
+            B  unique catalog cost required for HIGH; multi-cost candidate -> REVIEW.
+            C  pattern whose colorways all share ONE cost -> pattern-only match = HIGH.
+  Step 5  review diff -> out/cost-relink-diff.json + human summary.
+
+Pricing mirrors the live activation drain (final-split.js):
+  Kravet-family -> MAP as-is (kravet_price)
+  all others    -> round(catalog_cost / 0.65 / 0.85, 2)
+
+NOTHING is written to dw_unified. The relink WRITE stays gated for Steve.
