CNF Rear Geometry
Vicente Rear-Fit Certification Standard
V-RFC-02 — Multi-domain certification for Levi's cuts based on geometry, tension, cloth-body distance, and multi-pose stability.
Certification Domains
Geometry Compatibility
| Metric | Threshold |
|---|---|
| Projection mismatch | ≤ 4 mm |
| Curvature mismatch | ≤ 0.12 |
| Contour stability | ≥ 0.90 |
Tension Behavior
| Zone | Max Tension |
|---|---|
| Upper seat | 0.15 |
| Side seam | 0.18 |
| Thigh | 0.16 |
Cloth-Body Distance
| Zone | Ratio |
|---|---|
| Tight | ≤ 0.22 |
| Relaxed | ≤ 0.30 |
Multi-Pose Stability
| Metric | Threshold |
|---|---|
| Projection variance | ≤ 4 mm |
| Curvature variance | ≤ 0.10 |
| Tension variance | ≤ 0.08 |
Cohort Performance
| Metric | Threshold |
|---|---|
| Acceptance rate | ≥ 0.75 |
| Return rate | ≤ 0.12 |
| Comfort score | ≥ 0.85 |
Certification Decision
A Levi's cut is VICENTE-CERTIFIED if it passes ≥ 4 of 5 domains and has no critical fails.
Critical fails: upper-seat tension > 0.20, projection mismatch > 8 mm, curvature mismatch > 0.15, cohort acceptance < 60%.
