Remarks

Exists for one reason: to keep ReceivedUtcTicks off the wire.

The field is server-internal. ChatSystem.OnServerChatBroadcastReceived stamps it at the network boundary and it is read only by the spam token bucket and the audit persistence, all server side — no client has ever read it. But the server re-broadcasts the same struct it received, so the generated serializer put a full DateTime.UtcNow.Ticks on every outbound message: roughly 6.4e17, which zigzags to 61 significant bits and costs NINE varint bytes. On a short line of say chat that was about half the packet, paid to every observer of the sender, on the most fanned-out message in the game.

Not written and not read, rather than zeroed at each fanout site: there are more than twenty send sites and a new one would silently reintroduce the cost. Leaving it out of the format makes the field's own documentation true in both directions — a client cannot assert a receive time it did not observe, and the server always stamps its own.

Discovered by FishNet's codegen through the Write*/Read* naming convention.
