Decouple the displayed opponent name from the small pool of durable robot accounts: the disguised auto-match robot now gets a freshly composed name each game, stamped on a new game_players.display_name seat snapshot. The snapshot also captures humans' names, freezing what an opponent sees for the life of a game (a later rename no longer rewrites past games); readers fall back to the account's current name for pre-migration rows. Names come from a wide composed corpus (internal/robot/namevariety.go): Western locales (EN/DE/ES/IT/FR/PT), native Japanese/Chinese names, a gender-agreed Russian pool, and human-style handles. Routing keeps Pick's spirit -- a Russian game draws Cyrillic + <=20% Latin and never a CJK script; an English game the full corpus -- via robot.PickNamed. Loosen account.ValidateDisplayName (and the UI mirror) to admit a trailing run of up to five digits, so "Player2007"-style handles are valid for humans too and the disguised robot stays indistinguishable. Migration 00007 adds game_players.display_name (additive, NOT NULL DEFAULT ''); jet regenerated. Docs (ARCHITECTURE 7, FUNCTIONAL + _ru, PLAN, README) updated.
