  "rationale": "BELOW TARGET. Authors acknowledge in §4: 'the sample size chosen for experimental testing may not meet a statistically relevant sample size' — encoded as a factor-level shortfall here. The N=11 sample size partly compensates per ASTM spinal device convention. The shortfall is documented in the decision rationale rather than blocking acceptance.",
