# START HERE — V393

Active checkpoint: **V393 Hurdle Stretch natural neutral + deeper quad stretch**.

V393 changes canonical pose data only: relaxed neutral arm hang and greater quad-stretch knee flexion. Canonical hurdle IK owns the full body and both legs. Existing V50/V338/V339 generic grip is restricted to the active arm/hand/palm contact branch. No new solver.
