	The pooled particle (position/weight/ids/level/payload).

bool	exposed = false
	Whether this local valid particle's cell touches a patch boundary (has ghost targets). Always false for ghosts.

Detailed Description

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

Pooled per-round record for one particle: the particle plus its cached boundary-exposure flag.

particlesByID maps every local valid particle and every ghost to one of these. Folding the exposure flag in (it used to live in a separate id->bool map filled in the same gather loop) lets the gather do one hash insert per particle instead of two, and resolveTrivialTier() one lookup per query/candidate instead of two. exposed is meaningful only for local valid particles; ghosts always carry false (a ghost never initiates a query, and candidate-side exposure is gated on locality).

Template Parameters

Packed Caller-defined payload type (see MergeParticle).
