`schema:name`	Nagaraja COU1 — Non-cannulated pedicle screw compression-bending credibility assessment
`schema:description`	V&V 40 credibility assessment for FEA prediction of ASTM F1717 static compression-bending performance of a non-cannulated 7.5 mm pedicle screw construct. COU1 is the validation activity itself — the FEA model ensemble (FDA, Ansys, DePuy Synthes) is compared against N=11 experimental constructs across two laboratories. All 13 V&V 40 factors assessed; one factor (Test conditions) below required level due to single test condition.
