# V346 rebuilt from V345

Reproduced 2026-08-21 from `NEXT11_V345_HURDLE_MESH_PROXY_REGRESSION_PASS.zip` using only the documented V346 patch from the active conversation.

Changes reproduced:
- generic lower-leg proxy resolution accepts Foot/Calf and Calf/Thigh receiver descriptions;
- Calf/Thigh with receiver band touching Calf boundary maps to the proximal-shin region of the central lower-leg collision proxy;
- longitudinal distance is preserved from the Calf/knee boundary;
- no exercise-name branch or new grip solver is introduced.
