games.cavu.tier-madness.lobby

Announces that a game exists and is taking players. Written by the host, from their own PDS, to their public repo (rkey = game id). Players join by giving the game server the game's 4-character code; the code itself is never published. codeHash is an HMAC of the code under the space host's secret key: unkeyed, all ~1M codes could be hashed in about a second. The server indexes lobbies by codeHash and hashes the code a player gives it.
