### Scope - New "Identities" tab on the segment view (peer of the rule editor). - Environment selector at the top of the tab. - Member count + `as_of` timestamp. - Paginated list with identifier search (debounced, server-side filter). - Empty / warming / error states. - E2E test covering: load tab → switch env → search. ### Acceptance criteria - Tab is visible on the segment view for users with both required permissions. - Empty state with clear copy when permissions are missing, naming the missing one. - Search uses the API filter, not client-side filtering.
