A full send buffer dropped the oldest event and then the new one too while
reporting one drop. Subscribe accepted routeTypes and observerIds but never
applied them.
Warn at startup when limits are on without trusted_proxies, and once when a
request carries forwarding headers Beacon ignores. Reject short or whitespace
admin keys and negative durations. Key default-window stats by hour, return
500 for scope lookup failures, and validate IATA path params.
Duplicate observations are dropped before the hub today, so a live map only sees each packet's first hearing per observer. Clients that configure includeRepeats also get later hearings whose path is new; nothing is stored, repeats skip the count query, and they are dropped first when the broadcast channel is half full.
