-- Logical game-alias join guidance for Select AI.

-- COMN_GAME_ALIAS_BAS intentionally has multiple alias rows per GAME_ID, so
-- GAME_ID cannot be modelled as a physical foreign key to that table.  These
-- annotations describe the safe semantic relationship without asserting a
-- false database constraint or creating fan-out aggregation errors.
