Messages Costume - NexusTomorrow/server GitHub Wiki

reference, committed verified 2026-10-18 bootstrap 5aae370

Every message in the Costume area: its opcode, direction, how far it is verified, and its fields.

This area groups messages by the client feature they belong to; a message may sit here provisionally until its reading confirms the area. None is verified to its purpose yet, so this page claims nothing about what they do.

[!NOTE] Generated from the message declarations at bootstrap 5aae370 by Tools/NexusTomorrow.ProtocolReference. Don't edit it by hand: change the declaration's documentation and regenerate.
