Pos	1	2	3	4	5	6	7	8	9	10	11	12

Step 1: Sum of Odd Positions (1, 3, 5, 7, 9, 11) 0 + 3 + 0 + 0 + 1 + 0 = 4

Step 2: Multiply Odd Sum by 3 (GS1 Weighting) 4 × 3 = 12

Step 3: Sum of Even Positions (2, 4, 6, 8, 10) 3 + 2 + 0 + 1 + 1 = 7

Step 4: Grand Total Sum (S = Weighted Odd + Even) 12 + 7 = 19

Step 5: Check Digit = (10 - (S mod 10)) mod 10 (10 - (19 mod 10)) mod 10 = 1

True Positives (TP) MATCH

Identical sovereign retail items correctly unified.

False Positives (FP) COLLISION

Pack-size collisions falsely accepted. Hallucinates fake spreads!

False Negatives (FN) DROPPED

Legitimate matches dropped due to minor text formatting.

True Negatives (TN) REJECTED
