Engine: multi-player drop-out-and-continue with a per-game tile disposition (remove default / return), resigned seats skipped and excluded from the win, leaver rack never revealed; 2-player behaviour unchanged. New domains (service/store, no HTTP yet): internal/social (friend request/accept graph, per-user blocks, per-game chat with nudge as a message kind, content filter via mvdan.cc/xurls/v2 + leet/separator normaliser + phone heuristic) and internal/lobby (in-memory variant-keyed matchmaking pool, friend-game invitations invite->accept with lazy 7-day expiry). account gains profile editing and the email confirm-code flow (Mailer seam: SMTP or log mailer). Migration 00003_social.sql + regenerated jet. main wires the new services into the server (accessors for the Stage 6 handlers); robot substitution stays in Stage 5, REST/stream/push in Stage 6/8. Docs (PLAN, ARCHITECTURE, FUNCTIONAL+ru, TESTING, README) updated.

// Package lobby forms games: an in-memory matchmaking pool that pairs two humans
|
|
// for an auto-match, and friend-game invitations (invite -> accept) that start a
|
|
// 2-4 player game once every invitee has accepted. Both produce a game through the
|
|
// game domain (a GameCreator); neither imports the engine. The matchmaking pool
|
|
// is in-memory and lost on restart (players re-queue); the robot that substitutes
|
|
// for a missing human after a short wait is added in a later stage.
