Public Attributes
MergeParticle< Packed >	source
	The proposer's own particle (full data) – always locally valid/owned by the sending rank.

ParticleID	targetID
	Global id of the particle being proposed to. Owned by the receiving (judge) rank.

Real	distanceSquared
	Squared distance between `source` and the target. Duplicated from the originating NNMergeEdge so the judge never needs to look anything up to sort/compare proposals.

Detailed Description

template<typename Packed>
struct ParticleManagement::detail::NNMergeProposal< Packed >

A cross-patch merge proposal: one particle's own nearest-neighbor query result, bundled as a self-contained, atomic pair for shipment to whichever rank owns the candidate.

Carries full data for both participants (not a bare id reference) so the judge's decision is self-contained and it can never recombine pieces across different incoming proposals. Routing rule (see generateProposals()): a proposal is always sent to the owner of the querying particle's best candidate, never by any id comparison.

Template Parameters
