Reliability not validity
Repeatable score ≠ Correct construct
GTO not spindle
Tension sensor ≠ Length sensor
Waiver not immunity
Risk transfer attempt ≠ Negligence shield
Visuals not trivia
Spot technique errors ≠ Recall definitions only
Protein not fuel
Repair priority ≠ High-intensity fuel
Plyos not conditioning
Quality contacts ≠ Fatigue volume
