Struct PeerCtx 

pub struct PeerCtx<'a> {
    pub gate: &'a mut PeerGate,
    pub backoff: &'a mut BackoffTable,
    pub governor: &'a mut PeerGovernor,
    pub addresses: &'a mut AddressBook,
    pub backpressure: &'a mut BackpressureTracker,
}

Per-peer state borrowed mutably during dispatch.

Fields

gate: &'a mut PeerGate

Per-peer concurrency limiter.

backoff: &'a mut BackoffTable

Per-peer exponential backoff state.

governor: &'a mut PeerGovernor

Peer policy + health source-of-truth.

addresses: &'a mut AddressBook

PeerId → (Vec<Address>, ref_count) registry.

backpressure: &'a mut BackpressureTracker

Receiver-side back-pressure tracker. RX gates + ingress detection sites consult this to record overload and decide between emitting a typed BackoffNotice envelope or silently dropping.
