pub fn record_ack_within_rate(
times: &mut Vec<u64>,
now: u64,
window: u64,
max: usize,
) -> boolExpand description
Per-peer ack rate gate (RFC-004 AC-HP3 — a 100-probe flood must yield ≤ a
handful of acks, bounded responder CPU). Prunes times to the window, then:
>= max remaining → refuse the ack (false); else record now and allow
(true). Same sliding-window shape as the relay’s intro gate. Pure →
unit-tested. The daemon holds times per peer in a process-static map.
