Friendship (request/accept/decline/remove, self-request and crossing-request
handling, DB-level pair uniqueness via a hand-written expression index),
ChatRoom/ChatMessage/ChatReadState backed by Nitro's built-in websocket
(server/api/v1/community/ws.get.ts) behind a ChatTransport seam
(server/internal/community/chatTransport.ts) with a REST send fallback.
Mid-milestone product redirect: chat's primary job is coordinating the
persistent-world servers (EQEmu/WoW/DAoC), not per-title discussion --
ChatRoomKind gets a first-class `server` case and chatService.ts ships a
static KNOWN_SERVERS registry keyed the same way M4's GameServer will be,
once that lands (gameServerId reserved for that wiring-up pass).
Presence has no new table -- "online" is a live websocket registry
(presenceRuntime.ts), "playing X" reads through an isolated query module
(presenceService.ts) that degrades to an empty, clearly-labeled result if
PlaySession's shape doesn't match what it expects.
Pages: /community/friends, /community/chat, plus a friends/servers strip on
/community itself. Migration 20260803120000_m3_friends_chat.
