-- inbox UI's deduplicated view: notifications are grouped per issue
-- (Linear-style, one row per issue) and an issue counts as unread only when
-- its NEWEST non-archived item is unread. Opening an issue marks just that
-- newest item read, so counting raw unread rows would keep older siblings
-- alive and light the switcher dot for a workspace whose inbox the user sees
-- as empty (MUL-3695). Items without an issue group on their own id. The
-- member join keeps counts scoped to workspaces the user still belongs to,
-- so a stale item left behind in a workspace the user has since left cannot
-- light the dot.
