Namespaces
namespace	data
namespace	particle
	Collection of methods and data related to particle object.

Functions
bool	particle::isLocallyOwned (const BaseParticle &p)
	True if this rank updates / assembles forces for the particle. Walls are replicated on every rank. With one MPI rank, everything is local.
std::string	particle::resolvedMpiStrategy (const data::ModelData &data)
	Resolved MPI strategy: none|particle|dof (auto expanded).
void	particle::assignMpiOwners (data::ModelData &data)
	Assign grain owners by spatial 2D brick decomposition of centers. Walls get owner -1 (all ranks). Honors Model.MPI_Strategy.
void	particle::exchangeGhostKinematics (data::ModelData &data)
	Distance-limited ghosts + kinematics exchange. Rebuilds the ghost plan on a Verlet-skin cadence (tied to contact neigh interval when available); between rebuilds only exchanges kinematics for the cached ghost set via Alltoallv.
