Legal document redaction requires verifying that blacked-out confidential text is permanently stripped from underlying PDF vector content streams, rather than merely covered by superficial visual black rectangles that can be copied or deleted. In this document security sizing utility, redaction sanitization is modeled with three inputs: a document vector content complexity factor ($V_1$), a visual redaction layer multiplier ($V_2$), and a text stream parsing divisor ($V_3$).

The utility evaluates the primary sanitization verification index ($[V_1 imes V_2] / max(0.01, V_3)$), the intermediate structural security factor ($sqrt{max(0, V_1 imes V_2)}$), and the relative redaction coverage confidence share ($[V_1 / (V_1 + V_2)] imes 100$).

### Distinct Worked Calculation Evaluating a multi-page legal brief with extensive vector redaction boxes: - Vector Complexity Factor ($V_1$): 142 - Visual Redaction Multiplier ($V_2$): 34 - Stream Parsing Divisor ($V_3$): 4

Step-by-step results: - Primary Sanitization Metric: $(142 imes 34) / 4 = 1207.00$ - Structural Security Root: $sqrt{142 imes 34} = sqrt{4828} approx 69.48$ - Redaction Confidence Share: $[142 / (142 + 34)] imes 100 = (142 / 176) imes 100 approx 80.68%$
