Detailed Description

Hertz–Mindlin force-law policy (the first force law; see file comment).

Owns the law-specific parts: pair-list/history rebuild semantics, wall candidates, and the force kernels. Per-pair state: Mindlin shear history xi (+ lagged patch stiffness snPair, reset at rebuild); per- (particle, wall) state: xiWall/snWall.
