-- Per-game friend requests sent to a disguised-robot opponent. A disguised robot is a
-- shared pool account reused across games under different per-game names, so such a
-- request must never go into `friendships` (that would befriend/await the shared robot
-- account, leak that it is a bot across the requester's other games under other names,
-- and pin the in-game "request sent" state to the shared account instead of this seat).
-- Each request is recorded here against the specific game + seat, snapshotting the name
-- the player saw, so the in-game scoreboard can re-mark that one seat as already
-- requested. The robot ignores it (it never becomes a friendship); a background reaper
-- deletes a row once its game has been finished for more than the retention window.
