-- 016_update_checks.sql — WI-14 "update available" detection.
--
-- One row per instance: the result of the last manual update check
-- (installed buildid from the Steam ACF vs the latest buildid for the
-- instance's branch from steamcmd app_info). CHECK-ONLY bookkeeping —
-- nothing in the panel acts on this table automatically.
