Contract #826 (§6.2 Isolation: DELETE …/isolate with hide_isolation_events; §8.2 readable set, §8.8, §9.2 / the message's readable set; §6.15 card history by at). Oliver, 2026-10-31 (inbox): when lifting an isolation, readable by default, a checkbox hides the isolation's events. Why: context/members.md (entry after 66d4076f).

Hub: DELETE …/members/{id}/isolate takes {"hide_isolation_events": true}; store the window (from_seq = head at isolation, to_seq = head at lift) as isolation_windows on the membership (migration through the queue) and show it in the member view to the readers of isolated; filter every read path of that membership: GET /events (whatever its trust, as actor too, through conversations), project messages §8.8, group-chat earlier history and its attachments §9.2, card history entries by at within the window's time span. Tests for an admin-trust agent and for re-adding it to a group chat.
