reference, committed verified 2026-10-23 dev c08ca81

Every message in the MatchingGame 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.
