CNF Rear Geometry

CNF Multi-Pose Stability Standard

Certification thresholds for rear-geometry stability across standing, walking, seated, and hip-hinge poses.

Measurement Protocol

Each candidate is scanned in four standard poses:

  • Standing (neutral)
  • Walking (mid-stride)
  • Seated (on flat surface, pelvis neutral)
  • Hip-hinge (45° forward lean, spine extended)

Stability Thresholds

MetricThreshold
Projection variance≤ 4 mm across poses
Curvature variance≤ 0.10 across poses
Tension variance≤ 0.08 across zones

Pose-Specific Notes

  • Standing — Baseline. All targets derived from this pose.
  • Walking — Tests dynamic projection and side-seam tension.
  • Seated — Tests rise curve and upper-seat compression.
  • Hip-hinge — Tests yoke angle and rear curvature under stretch.

Vicente Baseline

Vicente Noriega's geometry defines the multi-pose stability standard:

  • Projection variance: ≤ 4 mm
  • Curvature variance: ≤ 0.10
  • Tension variance: ≤ 0.08

These thresholds are embedded in Master Mold v3.0+ and used to certify new candidates.
