Struct ScoredPeer 

Source 
pub struct ScoredPeer {
    pub effective_score: f64,
    pub headroom: u32,
    pub exploratory: bool,
    pub tie_break: u64,
}
Expand description

A per-peer scored candidate: the effective score + the concurrency headroom + whether it is a cold exploratory pick. The engine ranks by effective_score (desc) and dispatches by headroom.

Fields§

§effective_score: f64

The peer’s registry index-free identity is carried by the engine; here we hold the score parts. The higher, the better (SPEC §4.4-A).

§headroom: u32

The recommended concurrent-range headroom for this peer (its learned saturation point minus its current in-flight, >= 0; a selected peer gets >= 1). Anti-herd (SPEC §4.4-B, §4.5).

§exploratory: bool

Whether this is a cold exploratory pick (SPEC §4.4-E).

§tie_break: u64

A stable tie-break salt (derived from the peer id) so equal scores order deterministically (SPEC §4.4-F) unless the engine’s seeded RNG chooses among cold peers.
