pub const EVENT_CHANNEL_CAPACITY: usize = 256;Expand description
Capacity of the event channel (DW-044). Bound chosen for alert-rate
shapes: transition events are rare per upstream (a breaker flapping
once per open_ms, ejections once per eject_ms), so 256 queued
events is already a gateway in serious trouble — beyond it, drops
(counted, gauge-exported) are the right answer, not buffering.
